1 Introduction

Acute pancreatitis (AP) is a disease that leads to pancreaticinflammation related to the premature activation of digestiveenzymesThe incidence of this disease has increased in recentyears [1] which has contributed to a significant increase inmortality mainly caused by complications of this conditionsuch as the systemic inflammatory response [2]

The treatment of AP is primarily symptomatic and basedon the initial evaluation of disease severity It is directed to

control pain promote supportive therapy meet the nutri-tional needs treat complications and prevent pancreaticinfection and spread of the inflammatory process to remoteorgans [3] The lack of specific therapy for AP along withthe high mortality rates observed in severe cases makesexperimental studies to find new treatment alternatives ofgreat interest

Among the sources of new medicinal active principlesnatural products with proven antioxidant potential are ofinterest for the treatment of AP since the local release

of reactive oxygen species (ROS) and inflammatory cellinfiltration in the pancreas play a key role in the developmentof AP and complications associated with this condition [4]

The fruit ofVacciniummacrocarpon Aiton (Ericaceae) ispopularly known as cranberry and is used to make juices andsauces throughout North America Due to promising resultsthe medicinal use of this plant has spread throughout tothe Western world [5] It contains anthocyanins flavonoidsproanthocyanidins condensed tannins and phenolic acidsRecent studies have shown that an extract of fruits of Vmacrocarpon containing approximately 182 anthocyaninscan attenuate hepatic inflammation in obese mice [6] andinhibit the adhesion of pathogenic E coli in patients withrecurrent urinary tract infection [7] In addition treatmentwith this extract led to decreased intestinal inflammation inobese mice [5] Clinically cranberry preparations have beenused in the treatment of urinary tract diseases and vascularinflammation demonstrating high therapeutic potential [8]which may still be underestimated

The need for new therapeutic options to treat AP alongwith the potential anti-inflammatory and antioxidant effectpresented by cranberry makes it a viable alternative for thetreatment pancreatitis Thus we investigated the possibleeffect of a hydroethanolic extract of fruits of Vacciniummacrocarpon (HEVm) in experimental AP in mice

2 Material and Methods

21 Plant Material The hydroethanolic extract of fruits ofVacciniummacrocarpon (HEVm)was purchased fromFagronBV lot number 14083757D with certificate of quality controlanalysis (HHHC140402)

22 Characterization of Hydroethanolic Extract of Fruitsof Vaccinium macrocarpon Samples were dissolved withmethanol water (70 30 v v) acidified with 5 acetic acidusing an ultrasound bath (Ultrasonic Cleaner 8892E-DTHCole-Parmer Illinois USA) After 10min at room temper-ature the dissolved extract was centrifuged at 3500timesg for10min at 4∘C This procedure was repeated 3 times and thesupernatants were combinedThe supernatants were reducedunder vacuum at 40∘C in a rotary evaporator (RotavaporRE 120 Buchi Flawil Switzerland) prior to passage througha C-18 extraction column (1 g) (Supelclean LC-18 SupelcoPennsylvania USA) previously conditioned with methanoland ultrapure water The sample was loaded into the columnand washed with ultrapure water The phenolic compoundswere eluted with methanol acidified with 03 HCl Theeluateswere completely dried using a rotary evaporator undervacuum at 40∘C resuspended in methanol acidified with5 acetic acid and filtered through a 045 120583m PVDF filter(Millipore Ltd) for the quantification of flavonoids by high-performance liquid chromatography-diode array detection(HPLC-DAD) analysis

Quantification of flavonoidswas carried out using anAgi-lent 1260 Infinity Quaternary LC System (Agilent Technolo-gies USA) coupled to a diode array detector (DAD)The col-umnusedwas a 5 120583mProdigyODS3 column (460times 250mm)(Phenomenex Ltd UK) with a flow rate of 1mLmin at 25∘C

The mobile phase consisted of waterformic acidacetonitrile(96 1 3 solvent A and 58 1 51 solvent B) The solventgradient was 10 B at the beginning 25 at 10 minutes31 at 15 minutes 40 at 20 minutes 50 at 30 minutes100 at 40 minutes 10 at 45 minutes and 10 at 50minutes Chromatograms were acquired at 270 370 and525 nm The flavonoids were identified by comparing theirretention times diode array spectral characteristics andmassspectra analyzed using LC-ESI-MSMS with the standardsand the data available in the literature The quantificationwas done using a calibration curve of the commercial stan-dards (catechin epicatechin from Sigma-Aldrich (St LouisMO USA) and cyanidin-3-O-glucoside from ExtrasyntheseGenay France)

The identification of the flavonoids was performed usinga Prominence Liquid Chromatograph (Shimadzu Japan)linked to an AmaZon SL ion trap mass spectrometer (BrukerDaltonics BremenGermany)with an electrospray ionization(ESI) interfaceThe solvent gradient conditionswere the sameas those used for the HPLC-DAD analysis After the samplewas passed through the DAD the flow rate was changedto 08mLmin for examination by the mass spectrometerThe ESI was used in the positive and negative mode Themass spectrometer operating condition was collision energyof 4500V for positive and negative mode The analysiswas carried out using a full scan from 119898119911 100 to 1500The compounds were identified according to mass spectralcharacteristics and comparison with literature data

23 Animals Male adult Swiss mice (30ndash35 g) were obtainedfrom the Animal Center of Federal University of SergipeThe animals were maintained at 21 plusmn 2∘C with free access tofood (Nuvilab) and filtered water under a 12 12 h lightdarkcycle All experimental procedures were approved by theEthics Committee for Animal Use in Research of FederalUniversity of Sergipe (protocol number 0916) and wereconducted in compliance with the Guide for Care and Use ofLaboratory Animals (National Institutes of Health) Duringthe experiments animals were randomly distributed amongthe experimental groups and the experimenter was unawareof each grouprsquos identification

24 Experimental Procedure Pancreatitis induction was per-formed by two intraperitoneal (ip) injections 1 h apartof L- arginine at the dose of 4 gkg [9] The solution forinjection contained 8 L-arginine in sterile saline with pHadjusted to 70 The control group received sterile saline(NaCl 09) Seventy-two hours after the last injectionthe animals were anesthetized (80mgkg of ketamine plus10mgkg of xylazine) euthanized by exsanguination andtranscardially perfused with saline plus heparin (5 IUL) andtissue samples (pancreas and lung) were collected Blood wascentrifuged at 1000timesg for 15min at room temperature toseparate serum samples Aliquots of serum and tissues werestored at minus80∘C for proper analysis

25 Experimental Design Animals were randomly dis-tributed into five groups (119899 = 5-6 each) In the saline +vehicle group animals were injected with sterile saline (09

5mLkg ip administration for 2 times) and treated with thevehicle (sterile saline ip) at 1 25 and 49 hours after the lastinjection of saline In the L-arginine + vehicle group animalswere injected with L-arginine (4 gkg ip administration for2 times) and treated with the vehicle (ip) at 1 25 and 49hours after the last injection of L-arginine In the three AP +HEVmgroups animals were injectedwith L-arginine (4 gkgip administration for 2 times) and treated with HEVm (50100 or 200mgkg po) at 1 25 and 49 hours after the lastinjection of L-arginine

Additional control groups were treated with dexametha-sone (5mgkg sc) at 1 25 and 49 hours after the last injec-tion of L-arginine (control for inflammatory parameters) ormorphine (5mgkg ip 30min before each measurementperformed at 24 48 and 72 h control for abdominal hyper-algesia) [10]

26Measurement of AbdominalHyperalgesia To evaluate themechanical hyperalgesia in the abdominal region of micewe used an electronic von Frey apparatus (Insight RibeiraoPreto Sao Paulo Brazil) according to Abreu et al [11] withminor adaptations On the day of testing mechanical stimuliwere applied to the anterior lateral region of the abdomenof the animals in triplicate prior to any manipulation and24 48 or 72 h after AP induction At each time point anincreasing stimulus (in g) was applied to the abdominalregion of themice with an interval of at least 1min apart untilany withdrawal behavior was observed and the thresholdforce (01 to 1000 g) value was registered by the equipment

This test was performed off-stage so that the examinerdid not know the identity of the groups Data were expressedas variation (Δ) by subtracting the mean value obtained fromthe three measurements taken at the time point referred toafter AP induction from the mean basal value recorded foreach animal (prior to pancreatitis)

27 Evaluation of Locomotor Activity The locomotor activityof mice was investigated in a circular open field apparatus(60 cm diameter Insight Ribeirao Preto Sao Paulo Brazil)as previously described [12] The animals (119899 = 5) werepretreated with HEVm (200mgkg) or vehicle (1 h before)or diazepan (1mgkg 30min before) and were individuallyplaced in the apparatus After 1min the distance traveled (m)mobility time (s) and number of lines crossedwere registeredover a period of 5min

28 Determination of Inflammatory Markers The edemaindex was calculated as the ratio of wet weight and dry weightof the samples of pancreatic tissue as previously described[10]

To determine myeloperoxidase (MPO) activity pancreasand lung samples were collected and homogenized withpotassium phosphate buffer (50mM pH 60 containing05 hexadecyltrimethylammonium bromide) Aliquots ofthe homogenates were centrifuged (2min 8000timesg 4∘C)and aliquots of the supernatants were incubated with a solu-tion of o-dianisidine hydrochloride (0167mgmL containing0005H2O2)TheMPOactivity wasmeasured kinetically inamicroliter plate scanner (Biotek) at 460 nmover a period of

5min Results were expressed as units of MPO per mg tissue(UMPOmg tissue) UMPOwas considered as the amount ofenzyme that degrades 1mmol of hydrogen peroxidemin [13]

Enzyme-linked immunosorbent assay (ELISA) forinterleukin- (IL-) 6 IL-1120573 and tumor necrosis factor-(TNF-) 120572was carried out in homogenate samples of pancreasand lung according to the manufacturerrsquos instructions (RampDSystems) The results were corrected by the amount oftissue protein and expressed as pg of each cytokinemg ofproteinThe protein content of tissues was determined by theBradford method using the Bio-Rad protein assay reagent

29 Determination of Biochemical Parameters in SerumBiochemical parameters in serum were assessed for eachexperimental group by using specific commercial kits foramylase (Katal Biotechnology Belo Horizonte MG Brazil)lipase (Human do Brasil Sao Paulo SP Brazil) aspar-tate aminotransferase (AST) and alanine aminotransferase(ALT) (Liquiform Labtest Lagoa Santa MG Brazil) accord-ing to each manufacturerrsquos instructions

210 Determination of Antioxidant Activity Samples of pan-creas and lungwere homogenized in phosphate buffer 50mMpH 70 centrifuged at 10000timesg and the supernatant wasused for all antioxidant assays

Lipid peroxidation was determined by the presence ofthiobarbituric acid reactive substances in samples of pancreasand lung homogenates by the method previously describedby Bose et al [14] with minor modifications [10] The resultswere expressed as pmol of malondialdehyde (MDA) formedper mg of protein

Pancreatic and lung nonprotein sulfhydryl groups (NP-SH) were determined by Ellmanrsquos reaction using 5101584051015840-dithio-bis-2-nitrobenzoic acid as previously described [15] Resultswere expressed as 120583g of NP-SHmg of protein

The determination of oxidized protein content (carbonylgroups) was performed [16] by the reaction of carbonylgroups and 24-dinitrophenylhydrazine The concentrationof carbonyl groups was calculated by using 215mMminus1 cmminus1as the extinction coefficient for aliphatic hydrazones and theresults were expressed as nmol of carbonylsmg of protein

Tissue antioxidant status was evaluated in the homoge-nate of pancreas and lung tissues using the ferric reducingantioxidant power (FRAP) assay [17] Results were plottedagainst a standard curve of ferrous sulphate (500ndash1500120583molL) and were expressed as 120583mol of ferrous sulphatemg ofprotein

Catalase (CAT) activity was appraised by the decrease inabsorption of H2O2 at 240 nm due to H2O2 consumptionby CAT as previously described [18] Specific activity wasexpressed as units of CATmg of protein

The activity of CuZn SODwas assayed by the adrenalinemethod based on the capacity of SOD to inhibit autoxidationof adrenaline to adrenochrome One unit of SOD activity wasdefined as the amount of protein causing 50 inhibition ofthe autoxidation of adrenaline at 26∘C [19]

Glutathione peroxidase (GSH-Px) activity was deter-mined as described previously [20] Enzyme activity was

32 Effect of HEVm on Inflammatory Parameters Pancreaticinflammation induced by L-arginine was characterized by amarked increase of pancreatic MPO activity after 72 h Thetreatment with HEVm at 200mgkg prevented this effect(119901 lt 0001) (Figure 2(a)) In addition the inductionof pancreatitis significantly increased MPO activity in thelung tissue compared with the saline group This effect wasalso reduced by the treatment with HEVm at 200mgkg(119901 lt 0001 Figure 2(b)) L-arginine administration enhancedpancreatic edema index after injection (515 plusmn 005 119901 lt0001) compared with the saline group (439 plusmn 008) and thetreatment with HEVm at 200mgkg produced a significantinhibition of this effect (438 plusmn 008 119901 lt 0001) as diddexamethasone (438 plusmn 009 119901 lt 0001) However thetreatment with HEVm at 50 or 100mgkg did not alter edema(514 plusmn 014 492 plusmn 014 resp)

In addition to the increase of the above-mentionedinflammatory parameters the levels of TNF-120572 IL-1120573 andIL-6 were significantly increased in pancreas and lung afterAP induction by L-arginine (Figures 3(a)ndash3(f)) comparedwith animals injected with saline The treatment with HEVmstrongly modulated the levels of these cytokines Levels ofTNF-120572 were significantly decreased by the treatment withHEVm in the pancreatic (119901 lt 001 and 119901 lt 005 respat 100 and 200mgkg Figure 3(a)) and lung tissue (119901 lt0001 at 50 100 and 200mgkg Figure 3(b)) compared

33 Effect of HEVm on Mechanical Abdominal Hyperalge-sia L-arginine-induced AP was accompanied by a markedreduction of the intensity of stimulus needed to causewithdrawal behavior in mice after 48 or 72 h denoting thatmice developed abdominal hyperalgesia as a consequence ofthe pancreatic inflammation Two-way ANOVA indicated asignificant interaction between the time and treatment in thisexperiment (119901 lt 0001 F = 3712) The injection of salineinstead of L-arginine did not alter the micersquos withdrawalbehavior (Figure 4) in comparison to basal evaluation

Figure 4 also demonstrates that the treatmentwithHEVmclearly reduced the abdominal hyperalgesia of mice submit-ted to AP after 48 h (119901 lt 001 at 50mgkg and 119901 lt 005at 100mgkg) or 72 h (119901 lt 0001 at 50mgkg 119901 lt 001 at100mgkg and 119901 lt 005 at 200mgkg)

As an experimental control treatment with morphineinhibited abdominal hyperalgesia stimulus at 24 (97 plusmn 1 g119901 lt 0001) 48 (83 plusmn 2 g 119901 lt 0001) and 72 h (58 plusmn 2 g119901 lt 0001) after induction of pancreatitis compared withanimals treated with the vehicle (minus37 plusmn 1 minus81 plusmn 1 andminus101 plusmn 1 g resp at 24 48 and 72 h after AP)

In addition pancreatic and lung nonprotein sulfhydrylgroups (NP-SH) were decreased by AP induction (Figures5(e) and 5(f)) Treatment with HEVm at the doses of 100and 200mgkg maintained the NP-SH content in pancreas(119901 lt 005 Figure 5(e)) and lung (119901 lt 0001 Figure 5(f))compared with animals treated with the vehicle

Additionally tissue antioxidant status was measured inthe pancreas and lung through the determination of thetotal antioxidant activity by the reduction of iron (FRAP)Figures 5(g) and 5(h) demonstrate that tissue antioxidantcapacity was significantly reduced in pancreas and lung afterAP induction and the treatment with 200mgkg of HEVmmaintained this capacity near the levels observed in animals

from the vehicle + saline group in both pancreas (119901 lt 005Figure 5(g)) and lung (119901 lt 0001 Figure 5(h))

Since the treatment with HEVm produced a markedantioxidant effect in pancreas and lung tissue of animals withpancreatitis the contribution of some antioxidant enzymesto this action was studied The induction of AP reducedthe activity of CAT SOD and GSH-Px enzymes in pancreasand CAT and SOD activities in lung (Figure 6) Figure 6(a)shows the increase in pancreatic CAT activity of mice treatedwith HEVm at doses of 50mgkg (119901 lt 001) 100mgkg(119901 lt 0001) and 200mgkg (119901 lt 001) A similar effectwas observed in lungs (Figure 6(b)) of animals treated withHEVm at doses of 50 (119901 lt 005) 100 (119901 lt 001) and

4 Discussion

The need for new experimental alternatives to treat AP isstill a challenge since there are no specific treatments forclinical management of this disease [3] In this study wepresent data that demonstrates that HEVm can modulatethe inflammatory response in pancreas and lung (with theparticipation of oxidative stress) and abdominal hyperalgesiaduring L-arginine-induced AP The finding that HEVm hasbeneficial effect in experimental pancreatitis is novel forthis extract which is frequently used by people to treatinflammatory conditions of the urinary system [8] Howeverthe presence of flavonoids in this extract supports the pos-sibility of a beneficial effect on AP For this reason we usedthe hydroethanolic extract of cranberry Our current datareinforce this hypothesis in themodel of pancreatitis inducedby L-arginine

The phytochemical analysis of HEVm showed that cat-echins and epicatechins are its major components It waspossible to identify three flavan-3-ols one flavonol andthree anthocyanins Catechin epicatechins and cyanidinderivatives were previously described in cranberry prepara-tions [21 22] as was quercetin-3-O-rutinoside (rutin) [23]These compounds exert various biological effects includingantioxidant and anti-inflammatory effects [11 21]

Treatment with HEVm induced protective effects againstpancreatic inflammation The activity of MPO edema indexand production of cytokines (TNF-120572 IL-1120573 and IL-6) werereduced by this extract Along with the lower pancreaticdamage in animals treated with HEVm the levels of serumamylase and lipase were lower which corroborates thereduction of pancreatic damage Neutrophil infiltration isa hallmark of AP [24] and our data show that HEVm caninterfere with the presence of these cells in the pancreasThisagrees with previous findings that cranberry extract reducesthe MPO activity in mice paws injected with carrageenan[23] Similarly treatment with 15 dried whole cranberrypowder (incorporated in the diet) reduced MPO activity inthe colon of mice submitted to dextran sulphate sodium-induced colitis [25] Altogether these results highlight theanti-inflammatory effect of the extract of fruits of V macro-carpon In accordance with this effect treatment with HEVmproduced antiedematogenic effect Corroborating this find-ing [23] showed that the extract of V macrocarpon fruitsreduces the production of prostaglandins in vitro possessesantioxidant activity and inhibits carrageenan-induced micepaw edema The reduction of neutrophil migration to thepancreas and edema formation induced by HEVm certainlyare dependent on the inhibitory activity of proinflammatorycytokines Our results demonstrate that pancreatic contentsof TNF-120572 IL-1120573 and IL-6were reduced by the treatmentwithHEVmOther studies have also demonstrated that the extractof cranberry inhibited IL-6 IL-8 and prostaglandin E2 pro-duction by gingival fibroblasts stimulated with lipopolysac-charide in vitro [26] and that serum IL-1120573 and interferon-120574 concentrations and TNF-120572 and IL-1120573 mRNA expressionin colon were reduced by treatment with cranberry inmice submitted to dextran sulphate sodium-induced colitis[25]

Besides pancreatic inflammation abdominal hyperalge-sia was observed 48 and 72 hours after pancreatitis inductionSimilar results were described by Abreu et al [11] in themodel of L-arginine-induced pancreatitis and we believethat this mimics the abdominal pain observed in humansafter an AP attack The reduction of AP-induced abdom-inal hyperalgesia by the treatment with HEVm may be aconsequence of the decrease of pancreatic inflammatorymediators such as TNF-120572 IL-1120573 and IL-6 However wecannot discard the possibility that substances present inHEVm blocked the stimulation of nociceptive pathwaysSince HEVm administration did not alter the locomotoractivity of mice we can exclude the possibility of muscularrelaxation or central nervous system depression that couldbias the nociceptive measurement Few studies have focusedon the possible analgesic effect of V macrocarpon fruits Arandomized clinical study demonstrated that men receivingradiation therapy for prostate cancer and taking cranberrycapsules presented lower incidence of pain and burning[27] The presence of flavonoids could also contribute tothis antihyperalgesic effect A previous study showed thatthe extract of grapefruit rich in proanthocyanidin (a classof flavonoids) reduced nociception caused by sciatic nerveligation-induced neuropathic pain in rats [28] In additionthe grapefruit extract reduced the nociception induced byformalin in mice by mechanisms involving the participationof opioid receptor activation [29] Concordantly a previousstudy by our group showed that rutin reduced abdominalhyperalgesia in L-arginine-induced pancreatitis in mice [11]

Following AP induction many extrapancreatic responseswere observed in animals injected with L-arginine such asthe increased MPO activity in lung and increased markersof hepatic injury Although the mechanisms underlyingthese alterations are not well understood in this modelof pancreatitis the beneficial effect of HEVm is supportedby these results Serum ALT and AST levels were used asmarkers of extrapancreatic alterations in the present studyThe increase in ALT but not AST is usually predictiveof biliary pancreatitis [30] However in the model of L-arginine-induced AP in rats other authors have shown thatboth AST and ALT are increased [31] but no study haspreviously measured these enzymes in mice Interestinglythis increase in hepatic enzymes was partially reduced by theadministration of HEVm which may in part be due to thereduction of pancreatic lesions as observed by the decreaseof pancreatic inflammatory markers and enzymes (amylaseand lipase)

Lung injury is the secondary effect of pancreatitismost related to mortality in patients [32] In the modelof L-arginine-induced pancreatitis lung MPO activity wasincreased 72 h after induction corroborating previous find-ings [9] The fact that the treatment with HEVm reducedlungMPOactivity is complementary to the above-mentionedextrapancreatic protective effects which might be a conse-quence of the reduction of pancreatic damage Pancreatitis-related lung injury is multifactorial and is associated withmany factors such as the presence of activated enzymesdestruction of the lung surfactant low lung perfusion ratesand increased cytokine in lung tissue [33] Interestingly

Evidence-Based Complementary and Alternative Medicine 11

in agreement with the decrease in lung MPO activity wedetected lower TNF-120572 IL-1120573 and IL-6 levels in lungs ofanimals treated with HEVm in comparison to the vehicle-treated group

Since theHEVm is rich in flavanols and other polyphenolsand these compounds have antioxidant effects [11 34 35] wespeculated that the beneficial actions observed in pancreaticand extrapancreatic parameters could take place with theinvolvement of antioxidant activity In fact increased TBARSand carbonyl groups in parallel with decreased NP-SH andtotal antioxidant capacity (FRAP) in both pancreas and lungindicated that oxidative stress plays a significant role inthis model as previously shown [11 36] Treatment withHEVm maintained antioxidant capacity of the tissue (NP-SH and FRAP) and consequently reduced the oxidationmarkers (MDA and carbonyl) which can be attributedto the direct antioxidant effect of polyphenols found inHEVm [11 22 23 34 37] Another reasonable possibility ofexplaining the antioxidant effect of HEVm is modulation ofthe activity of endogenous antioxidant enzymes Pancreatitisinduction was characterized by reduction of the activity ofCAT SOD and GPx in pancreas and lung corroboratingprevious findings [11] The CAT and SOD activities weremarkedly altered by the treatment with HEVm indicatingthat HEVm strongly modulates oxidative stress InterestinglyCAT and SOD activities seemed to be more susceptible toreversion in pancreas than in lung which agrees with theidea that the reduction of pancreatic damage was importantto the modulation of extrapancreatic effects The beneficialmodulation of CAT and SOD activities in animals treatedwith HEVm was more evident than GPx activity whichwas not altered by treatment with HEVm Indeed HEVmcountered the L-arginine-induced increase in oxidation anddecrease in antioxidative capacity

The antioxidant effects observed in the treatment withHEVm can be caused by the compounds present in thisextract The phenolic compounds found in HEVm likeanthocyanins rutin catechin and epicatechins and otherphenolic compounds (eg quercetin kaempferol ellagicacid and p-coumaric acid) are present in cranberries (forreview see [21 22]) and certainly contributed to the reductionof oxidative stress which in turn decreased the pancreaticlesions and resulted in less severe extrapancreatic alterationsin mice

An important concern about cranberry extracts is regard-ing their safety Many studies have found no toxicity aftertreatment with cranberry extracts for 6ndash10 weeks in exper-imental animals [5 6 38] or in humans [39 40] but arecent study found small differences in the spleen and kidneyfunction of the progeny ofmice treatedwith cranberry extractduring pregnancy [41]Thusmore specific studies are neededto assure the safety of cranberry extracts

Altogether our results indicate a protective role of HEVmin the model of AP induced by L-arginine by reducing pan-creatic damage hyperalgesia and remote alterations throughthe key participation of the antioxidant capacity of thisextract These findings provide insights into the possible useof this extract in the treatment of this disease

of reactive oxygen species (ROS) and inflammatory cellinfiltration in the pancreas play a key role in the developmentof AP and complications associated with this condition [4]

The fruit ofVacciniummacrocarpon Aiton (Ericaceae) ispopularly known as cranberry and is used to make juices andsauces throughout North America Due to promising resultsthe medicinal use of this plant has spread throughout tothe Western world [5] It contains anthocyanins flavonoidsproanthocyanidins condensed tannins and phenolic acidsRecent studies have shown that an extract of fruits of Vmacrocarpon containing approximately 182 anthocyaninscan attenuate hepatic inflammation in obese mice [6] andinhibit the adhesion of pathogenic E coli in patients withrecurrent urinary tract infection [7] In addition treatmentwith this extract led to decreased intestinal inflammation inobese mice [5] Clinically cranberry preparations have beenused in the treatment of urinary tract diseases and vascularinflammation demonstrating high therapeutic potential [8]which may still be underestimated

The need for new therapeutic options to treat AP alongwith the potential anti-inflammatory and antioxidant effectpresented by cranberry makes it a viable alternative for thetreatment pancreatitis Thus we investigated the possibleeffect of a hydroethanolic extract of fruits of Vacciniummacrocarpon (HEVm) in experimental AP in mice

2 Material and Methods

21 Plant Material The hydroethanolic extract of fruits ofVacciniummacrocarpon (HEVm)was purchased fromFagronBV lot number 14083757D with certificate of quality controlanalysis (HHHC140402)

22 Characterization of Hydroethanolic Extract of Fruitsof Vaccinium macrocarpon Samples were dissolved withmethanol water (70 30 v v) acidified with 5 acetic acidusing an ultrasound bath (Ultrasonic Cleaner 8892E-DTHCole-Parmer Illinois USA) After 10min at room temper-ature the dissolved extract was centrifuged at 3500timesg for10min at 4∘C This procedure was repeated 3 times and thesupernatants were combinedThe supernatants were reducedunder vacuum at 40∘C in a rotary evaporator (RotavaporRE 120 Buchi Flawil Switzerland) prior to passage througha C-18 extraction column (1 g) (Supelclean LC-18 SupelcoPennsylvania USA) previously conditioned with methanoland ultrapure water The sample was loaded into the columnand washed with ultrapure water The phenolic compoundswere eluted with methanol acidified with 03 HCl Theeluateswere completely dried using a rotary evaporator undervacuum at 40∘C resuspended in methanol acidified with5 acetic acid and filtered through a 045 120583m PVDF filter(Millipore Ltd) for the quantification of flavonoids by high-performance liquid chromatography-diode array detection(HPLC-DAD) analysis

Quantification of flavonoidswas carried out using anAgi-lent 1260 Infinity Quaternary LC System (Agilent Technolo-gies USA) coupled to a diode array detector (DAD)The col-umnusedwas a 5 120583mProdigyODS3 column (460times 250mm)(Phenomenex Ltd UK) with a flow rate of 1mLmin at 25∘C

The mobile phase consisted of waterformic acidacetonitrile(96 1 3 solvent A and 58 1 51 solvent B) The solventgradient was 10 B at the beginning 25 at 10 minutes31 at 15 minutes 40 at 20 minutes 50 at 30 minutes100 at 40 minutes 10 at 45 minutes and 10 at 50minutes Chromatograms were acquired at 270 370 and525 nm The flavonoids were identified by comparing theirretention times diode array spectral characteristics andmassspectra analyzed using LC-ESI-MSMS with the standardsand the data available in the literature The quantificationwas done using a calibration curve of the commercial stan-dards (catechin epicatechin from Sigma-Aldrich (St LouisMO USA) and cyanidin-3-O-glucoside from ExtrasyntheseGenay France)

The identification of the flavonoids was performed usinga Prominence Liquid Chromatograph (Shimadzu Japan)linked to an AmaZon SL ion trap mass spectrometer (BrukerDaltonics BremenGermany)with an electrospray ionization(ESI) interfaceThe solvent gradient conditionswere the sameas those used for the HPLC-DAD analysis After the samplewas passed through the DAD the flow rate was changedto 08mLmin for examination by the mass spectrometerThe ESI was used in the positive and negative mode Themass spectrometer operating condition was collision energyof 4500V for positive and negative mode The analysiswas carried out using a full scan from 119898119911 100 to 1500The compounds were identified according to mass spectralcharacteristics and comparison with literature data

23 Animals Male adult Swiss mice (30ndash35 g) were obtainedfrom the Animal Center of Federal University of SergipeThe animals were maintained at 21 plusmn 2∘C with free access tofood (Nuvilab) and filtered water under a 12 12 h lightdarkcycle All experimental procedures were approved by theEthics Committee for Animal Use in Research of FederalUniversity of Sergipe (protocol number 0916) and wereconducted in compliance with the Guide for Care and Use ofLaboratory Animals (National Institutes of Health) Duringthe experiments animals were randomly distributed amongthe experimental groups and the experimenter was unawareof each grouprsquos identification

24 Experimental Procedure Pancreatitis induction was per-formed by two intraperitoneal (ip) injections 1 h apartof L- arginine at the dose of 4 gkg [9] The solution forinjection contained 8 L-arginine in sterile saline with pHadjusted to 70 The control group received sterile saline(NaCl 09) Seventy-two hours after the last injectionthe animals were anesthetized (80mgkg of ketamine plus10mgkg of xylazine) euthanized by exsanguination andtranscardially perfused with saline plus heparin (5 IUL) andtissue samples (pancreas and lung) were collected Blood wascentrifuged at 1000timesg for 15min at room temperature toseparate serum samples Aliquots of serum and tissues werestored at minus80∘C for proper analysis

25 Experimental Design Animals were randomly dis-tributed into five groups (119899 = 5-6 each) In the saline +vehicle group animals were injected with sterile saline (09

5mLkg ip administration for 2 times) and treated with thevehicle (sterile saline ip) at 1 25 and 49 hours after the lastinjection of saline In the L-arginine + vehicle group animalswere injected with L-arginine (4 gkg ip administration for2 times) and treated with the vehicle (ip) at 1 25 and 49hours after the last injection of L-arginine In the three AP +HEVmgroups animals were injectedwith L-arginine (4 gkgip administration for 2 times) and treated with HEVm (50100 or 200mgkg po) at 1 25 and 49 hours after the lastinjection of L-arginine

Additional control groups were treated with dexametha-sone (5mgkg sc) at 1 25 and 49 hours after the last injec-tion of L-arginine (control for inflammatory parameters) ormorphine (5mgkg ip 30min before each measurementperformed at 24 48 and 72 h control for abdominal hyper-algesia) [10]

26Measurement of AbdominalHyperalgesia To evaluate themechanical hyperalgesia in the abdominal region of micewe used an electronic von Frey apparatus (Insight RibeiraoPreto Sao Paulo Brazil) according to Abreu et al [11] withminor adaptations On the day of testing mechanical stimuliwere applied to the anterior lateral region of the abdomenof the animals in triplicate prior to any manipulation and24 48 or 72 h after AP induction At each time point anincreasing stimulus (in g) was applied to the abdominalregion of themice with an interval of at least 1min apart untilany withdrawal behavior was observed and the thresholdforce (01 to 1000 g) value was registered by the equipment

This test was performed off-stage so that the examinerdid not know the identity of the groups Data were expressedas variation (Δ) by subtracting the mean value obtained fromthe three measurements taken at the time point referred toafter AP induction from the mean basal value recorded foreach animal (prior to pancreatitis)

27 Evaluation of Locomotor Activity The locomotor activityof mice was investigated in a circular open field apparatus(60 cm diameter Insight Ribeirao Preto Sao Paulo Brazil)as previously described [12] The animals (119899 = 5) werepretreated with HEVm (200mgkg) or vehicle (1 h before)or diazepan (1mgkg 30min before) and were individuallyplaced in the apparatus After 1min the distance traveled (m)mobility time (s) and number of lines crossedwere registeredover a period of 5min

28 Determination of Inflammatory Markers The edemaindex was calculated as the ratio of wet weight and dry weightof the samples of pancreatic tissue as previously described[10]

To determine myeloperoxidase (MPO) activity pancreasand lung samples were collected and homogenized withpotassium phosphate buffer (50mM pH 60 containing05 hexadecyltrimethylammonium bromide) Aliquots ofthe homogenates were centrifuged (2min 8000timesg 4∘C)and aliquots of the supernatants were incubated with a solu-tion of o-dianisidine hydrochloride (0167mgmL containing0005H2O2)TheMPOactivity wasmeasured kinetically inamicroliter plate scanner (Biotek) at 460 nmover a period of

5min Results were expressed as units of MPO per mg tissue(UMPOmg tissue) UMPOwas considered as the amount ofenzyme that degrades 1mmol of hydrogen peroxidemin [13]

Enzyme-linked immunosorbent assay (ELISA) forinterleukin- (IL-) 6 IL-1120573 and tumor necrosis factor-(TNF-) 120572was carried out in homogenate samples of pancreasand lung according to the manufacturerrsquos instructions (RampDSystems) The results were corrected by the amount oftissue protein and expressed as pg of each cytokinemg ofproteinThe protein content of tissues was determined by theBradford method using the Bio-Rad protein assay reagent

29 Determination of Biochemical Parameters in SerumBiochemical parameters in serum were assessed for eachexperimental group by using specific commercial kits foramylase (Katal Biotechnology Belo Horizonte MG Brazil)lipase (Human do Brasil Sao Paulo SP Brazil) aspar-tate aminotransferase (AST) and alanine aminotransferase(ALT) (Liquiform Labtest Lagoa Santa MG Brazil) accord-ing to each manufacturerrsquos instructions

210 Determination of Antioxidant Activity Samples of pan-creas and lungwere homogenized in phosphate buffer 50mMpH 70 centrifuged at 10000timesg and the supernatant wasused for all antioxidant assays

Lipid peroxidation was determined by the presence ofthiobarbituric acid reactive substances in samples of pancreasand lung homogenates by the method previously describedby Bose et al [14] with minor modifications [10] The resultswere expressed as pmol of malondialdehyde (MDA) formedper mg of protein

Pancreatic and lung nonprotein sulfhydryl groups (NP-SH) were determined by Ellmanrsquos reaction using 5101584051015840-dithio-bis-2-nitrobenzoic acid as previously described [15] Resultswere expressed as 120583g of NP-SHmg of protein

The determination of oxidized protein content (carbonylgroups) was performed [16] by the reaction of carbonylgroups and 24-dinitrophenylhydrazine The concentrationof carbonyl groups was calculated by using 215mMminus1 cmminus1as the extinction coefficient for aliphatic hydrazones and theresults were expressed as nmol of carbonylsmg of protein

Tissue antioxidant status was evaluated in the homoge-nate of pancreas and lung tissues using the ferric reducingantioxidant power (FRAP) assay [17] Results were plottedagainst a standard curve of ferrous sulphate (500ndash1500120583molL) and were expressed as 120583mol of ferrous sulphatemg ofprotein

Catalase (CAT) activity was appraised by the decrease inabsorption of H2O2 at 240 nm due to H2O2 consumptionby CAT as previously described [18] Specific activity wasexpressed as units of CATmg of protein

The activity of CuZn SODwas assayed by the adrenalinemethod based on the capacity of SOD to inhibit autoxidationof adrenaline to adrenochrome One unit of SOD activity wasdefined as the amount of protein causing 50 inhibition ofthe autoxidation of adrenaline at 26∘C [19]

Glutathione peroxidase (GSH-Px) activity was deter-mined as described previously [20] Enzyme activity was

31 Phytochemical Analysis of HEVm Figure 1 shows theHPLC-DAD chromatograms of the HEVm extract andthe respective identification of the compounds by LC-ESI-MSMS is shown in Table 1 Seven compoundswere identified(three flavan-3-ols one flavonol and three anthocyanins)The major compounds were catechin and epicatechin (Fig-ure 1(a) peaks 1 and 2 119898119911 291) The main anthocyaninswere cyanidin-3-O-glucoside (119898119911 449 peak 6 Figure 1(b))followed by cyanidin-coumaroyl-hexoside (119898119911 595 peak7 Figure 1(b)) both with characteristic molecular ions ofcyanidin (119898119911 287) The total flavonoids content in pow-dered cranberry was 87565mg100 g where flavan-3-ol con-tributed 933 followed by flavonol (43) and anthocyanins(24)

32 Effect of HEVm on Inflammatory Parameters Pancreaticinflammation induced by L-arginine was characterized by amarked increase of pancreatic MPO activity after 72 h Thetreatment with HEVm at 200mgkg prevented this effect(119901 lt 0001) (Figure 2(a)) In addition the inductionof pancreatitis significantly increased MPO activity in thelung tissue compared with the saline group This effect wasalso reduced by the treatment with HEVm at 200mgkg(119901 lt 0001 Figure 2(b)) L-arginine administration enhancedpancreatic edema index after injection (515 plusmn 005 119901 lt0001) compared with the saline group (439 plusmn 008) and thetreatment with HEVm at 200mgkg produced a significantinhibition of this effect (438 plusmn 008 119901 lt 0001) as diddexamethasone (438 plusmn 009 119901 lt 0001) However thetreatment with HEVm at 50 or 100mgkg did not alter edema(514 plusmn 014 492 plusmn 014 resp)

In addition to the increase of the above-mentionedinflammatory parameters the levels of TNF-120572 IL-1120573 andIL-6 were significantly increased in pancreas and lung afterAP induction by L-arginine (Figures 3(a)ndash3(f)) comparedwith animals injected with saline The treatment with HEVmstrongly modulated the levels of these cytokines Levels ofTNF-120572 were significantly decreased by the treatment withHEVm in the pancreatic (119901 lt 001 and 119901 lt 005 respat 100 and 200mgkg Figure 3(a)) and lung tissue (119901 lt0001 at 50 100 and 200mgkg Figure 3(b)) compared

33 Effect of HEVm on Mechanical Abdominal Hyperalge-sia L-arginine-induced AP was accompanied by a markedreduction of the intensity of stimulus needed to causewithdrawal behavior in mice after 48 or 72 h denoting thatmice developed abdominal hyperalgesia as a consequence ofthe pancreatic inflammation Two-way ANOVA indicated asignificant interaction between the time and treatment in thisexperiment (119901 lt 0001 F = 3712) The injection of salineinstead of L-arginine did not alter the micersquos withdrawalbehavior (Figure 4) in comparison to basal evaluation

Figure 4 also demonstrates that the treatmentwithHEVmclearly reduced the abdominal hyperalgesia of mice submit-ted to AP after 48 h (119901 lt 001 at 50mgkg and 119901 lt 005at 100mgkg) or 72 h (119901 lt 0001 at 50mgkg 119901 lt 001 at100mgkg and 119901 lt 005 at 200mgkg)

In addition pancreatic and lung nonprotein sulfhydrylgroups (NP-SH) were decreased by AP induction (Figures5(e) and 5(f)) Treatment with HEVm at the doses of 100and 200mgkg maintained the NP-SH content in pancreas(119901 lt 005 Figure 5(e)) and lung (119901 lt 0001 Figure 5(f))compared with animals treated with the vehicle

Additionally tissue antioxidant status was measured inthe pancreas and lung through the determination of thetotal antioxidant activity by the reduction of iron (FRAP)Figures 5(g) and 5(h) demonstrate that tissue antioxidantcapacity was significantly reduced in pancreas and lung afterAP induction and the treatment with 200mgkg of HEVmmaintained this capacity near the levels observed in animals

from the vehicle + saline group in both pancreas (119901 lt 005Figure 5(g)) and lung (119901 lt 0001 Figure 5(h))

Since the treatment with HEVm produced a markedantioxidant effect in pancreas and lung tissue of animals withpancreatitis the contribution of some antioxidant enzymesto this action was studied The induction of AP reducedthe activity of CAT SOD and GSH-Px enzymes in pancreasand CAT and SOD activities in lung (Figure 6) Figure 6(a)shows the increase in pancreatic CAT activity of mice treatedwith HEVm at doses of 50mgkg (119901 lt 001) 100mgkg(119901 lt 0001) and 200mgkg (119901 lt 001) A similar effectwas observed in lungs (Figure 6(b)) of animals treated withHEVm at doses of 50 (119901 lt 005) 100 (119901 lt 001) and

4 Discussion

The need for new experimental alternatives to treat AP isstill a challenge since there are no specific treatments forclinical management of this disease [3] In this study wepresent data that demonstrates that HEVm can modulatethe inflammatory response in pancreas and lung (with theparticipation of oxidative stress) and abdominal hyperalgesiaduring L-arginine-induced AP The finding that HEVm hasbeneficial effect in experimental pancreatitis is novel forthis extract which is frequently used by people to treatinflammatory conditions of the urinary system [8] Howeverthe presence of flavonoids in this extract supports the pos-sibility of a beneficial effect on AP For this reason we usedthe hydroethanolic extract of cranberry Our current datareinforce this hypothesis in themodel of pancreatitis inducedby L-arginine

The phytochemical analysis of HEVm showed that cat-echins and epicatechins are its major components It waspossible to identify three flavan-3-ols one flavonol andthree anthocyanins Catechin epicatechins and cyanidinderivatives were previously described in cranberry prepara-tions [21 22] as was quercetin-3-O-rutinoside (rutin) [23]These compounds exert various biological effects includingantioxidant and anti-inflammatory effects [11 21]

Treatment with HEVm induced protective effects againstpancreatic inflammation The activity of MPO edema indexand production of cytokines (TNF-120572 IL-1120573 and IL-6) werereduced by this extract Along with the lower pancreaticdamage in animals treated with HEVm the levels of serumamylase and lipase were lower which corroborates thereduction of pancreatic damage Neutrophil infiltration isa hallmark of AP [24] and our data show that HEVm caninterfere with the presence of these cells in the pancreasThisagrees with previous findings that cranberry extract reducesthe MPO activity in mice paws injected with carrageenan[23] Similarly treatment with 15 dried whole cranberrypowder (incorporated in the diet) reduced MPO activity inthe colon of mice submitted to dextran sulphate sodium-induced colitis [25] Altogether these results highlight theanti-inflammatory effect of the extract of fruits of V macro-carpon In accordance with this effect treatment with HEVmproduced antiedematogenic effect Corroborating this find-ing [23] showed that the extract of V macrocarpon fruitsreduces the production of prostaglandins in vitro possessesantioxidant activity and inhibits carrageenan-induced micepaw edema The reduction of neutrophil migration to thepancreas and edema formation induced by HEVm certainlyare dependent on the inhibitory activity of proinflammatorycytokines Our results demonstrate that pancreatic contentsof TNF-120572 IL-1120573 and IL-6were reduced by the treatmentwithHEVmOther studies have also demonstrated that the extractof cranberry inhibited IL-6 IL-8 and prostaglandin E2 pro-duction by gingival fibroblasts stimulated with lipopolysac-charide in vitro [26] and that serum IL-1120573 and interferon-120574 concentrations and TNF-120572 and IL-1120573 mRNA expressionin colon were reduced by treatment with cranberry inmice submitted to dextran sulphate sodium-induced colitis[25]

Besides pancreatic inflammation abdominal hyperalge-sia was observed 48 and 72 hours after pancreatitis inductionSimilar results were described by Abreu et al [11] in themodel of L-arginine-induced pancreatitis and we believethat this mimics the abdominal pain observed in humansafter an AP attack The reduction of AP-induced abdom-inal hyperalgesia by the treatment with HEVm may be aconsequence of the decrease of pancreatic inflammatorymediators such as TNF-120572 IL-1120573 and IL-6 However wecannot discard the possibility that substances present inHEVm blocked the stimulation of nociceptive pathwaysSince HEVm administration did not alter the locomotoractivity of mice we can exclude the possibility of muscularrelaxation or central nervous system depression that couldbias the nociceptive measurement Few studies have focusedon the possible analgesic effect of V macrocarpon fruits Arandomized clinical study demonstrated that men receivingradiation therapy for prostate cancer and taking cranberrycapsules presented lower incidence of pain and burning[27] The presence of flavonoids could also contribute tothis antihyperalgesic effect A previous study showed thatthe extract of grapefruit rich in proanthocyanidin (a classof flavonoids) reduced nociception caused by sciatic nerveligation-induced neuropathic pain in rats [28] In additionthe grapefruit extract reduced the nociception induced byformalin in mice by mechanisms involving the participationof opioid receptor activation [29] Concordantly a previousstudy by our group showed that rutin reduced abdominalhyperalgesia in L-arginine-induced pancreatitis in mice [11]

Following AP induction many extrapancreatic responseswere observed in animals injected with L-arginine such asthe increased MPO activity in lung and increased markersof hepatic injury Although the mechanisms underlyingthese alterations are not well understood in this modelof pancreatitis the beneficial effect of HEVm is supportedby these results Serum ALT and AST levels were used asmarkers of extrapancreatic alterations in the present studyThe increase in ALT but not AST is usually predictiveof biliary pancreatitis [30] However in the model of L-arginine-induced AP in rats other authors have shown thatboth AST and ALT are increased [31] but no study haspreviously measured these enzymes in mice Interestinglythis increase in hepatic enzymes was partially reduced by theadministration of HEVm which may in part be due to thereduction of pancreatic lesions as observed by the decreaseof pancreatic inflammatory markers and enzymes (amylaseand lipase)

Lung injury is the secondary effect of pancreatitismost related to mortality in patients [32] In the modelof L-arginine-induced pancreatitis lung MPO activity wasincreased 72 h after induction corroborating previous find-ings [9] The fact that the treatment with HEVm reducedlungMPOactivity is complementary to the above-mentionedextrapancreatic protective effects which might be a conse-quence of the reduction of pancreatic damage Pancreatitis-related lung injury is multifactorial and is associated withmany factors such as the presence of activated enzymesdestruction of the lung surfactant low lung perfusion ratesand increased cytokine in lung tissue [33] Interestingly

Evidence-Based Complementary and Alternative Medicine 11

in agreement with the decrease in lung MPO activity wedetected lower TNF-120572 IL-1120573 and IL-6 levels in lungs ofanimals treated with HEVm in comparison to the vehicle-treated group

Since theHEVm is rich in flavanols and other polyphenolsand these compounds have antioxidant effects [11 34 35] wespeculated that the beneficial actions observed in pancreaticand extrapancreatic parameters could take place with theinvolvement of antioxidant activity In fact increased TBARSand carbonyl groups in parallel with decreased NP-SH andtotal antioxidant capacity (FRAP) in both pancreas and lungindicated that oxidative stress plays a significant role inthis model as previously shown [11 36] Treatment withHEVm maintained antioxidant capacity of the tissue (NP-SH and FRAP) and consequently reduced the oxidationmarkers (MDA and carbonyl) which can be attributedto the direct antioxidant effect of polyphenols found inHEVm [11 22 23 34 37] Another reasonable possibility ofexplaining the antioxidant effect of HEVm is modulation ofthe activity of endogenous antioxidant enzymes Pancreatitisinduction was characterized by reduction of the activity ofCAT SOD and GPx in pancreas and lung corroboratingprevious findings [11] The CAT and SOD activities weremarkedly altered by the treatment with HEVm indicatingthat HEVm strongly modulates oxidative stress InterestinglyCAT and SOD activities seemed to be more susceptible toreversion in pancreas than in lung which agrees with theidea that the reduction of pancreatic damage was importantto the modulation of extrapancreatic effects The beneficialmodulation of CAT and SOD activities in animals treatedwith HEVm was more evident than GPx activity whichwas not altered by treatment with HEVm Indeed HEVmcountered the L-arginine-induced increase in oxidation anddecrease in antioxidative capacity

The antioxidant effects observed in the treatment withHEVm can be caused by the compounds present in thisextract The phenolic compounds found in HEVm likeanthocyanins rutin catechin and epicatechins and otherphenolic compounds (eg quercetin kaempferol ellagicacid and p-coumaric acid) are present in cranberries (forreview see [21 22]) and certainly contributed to the reductionof oxidative stress which in turn decreased the pancreaticlesions and resulted in less severe extrapancreatic alterationsin mice

An important concern about cranberry extracts is regard-ing their safety Many studies have found no toxicity aftertreatment with cranberry extracts for 6ndash10 weeks in exper-imental animals [5 6 38] or in humans [39 40] but arecent study found small differences in the spleen and kidneyfunction of the progeny ofmice treatedwith cranberry extractduring pregnancy [41]Thusmore specific studies are neededto assure the safety of cranberry extracts

Altogether our results indicate a protective role of HEVmin the model of AP induced by L-arginine by reducing pan-creatic damage hyperalgesia and remote alterations throughthe key participation of the antioxidant capacity of thisextract These findings provide insights into the possible useof this extract in the treatment of this disease

5mLkg ip administration for 2 times) and treated with thevehicle (sterile saline ip) at 1 25 and 49 hours after the lastinjection of saline In the L-arginine + vehicle group animalswere injected with L-arginine (4 gkg ip administration for2 times) and treated with the vehicle (ip) at 1 25 and 49hours after the last injection of L-arginine In the three AP +HEVmgroups animals were injectedwith L-arginine (4 gkgip administration for 2 times) and treated with HEVm (50100 or 200mgkg po) at 1 25 and 49 hours after the lastinjection of L-arginine

Additional control groups were treated with dexametha-sone (5mgkg sc) at 1 25 and 49 hours after the last injec-tion of L-arginine (control for inflammatory parameters) ormorphine (5mgkg ip 30min before each measurementperformed at 24 48 and 72 h control for abdominal hyper-algesia) [10]

26Measurement of AbdominalHyperalgesia To evaluate themechanical hyperalgesia in the abdominal region of micewe used an electronic von Frey apparatus (Insight RibeiraoPreto Sao Paulo Brazil) according to Abreu et al [11] withminor adaptations On the day of testing mechanical stimuliwere applied to the anterior lateral region of the abdomenof the animals in triplicate prior to any manipulation and24 48 or 72 h after AP induction At each time point anincreasing stimulus (in g) was applied to the abdominalregion of themice with an interval of at least 1min apart untilany withdrawal behavior was observed and the thresholdforce (01 to 1000 g) value was registered by the equipment

This test was performed off-stage so that the examinerdid not know the identity of the groups Data were expressedas variation (Δ) by subtracting the mean value obtained fromthe three measurements taken at the time point referred toafter AP induction from the mean basal value recorded foreach animal (prior to pancreatitis)

27 Evaluation of Locomotor Activity The locomotor activityof mice was investigated in a circular open field apparatus(60 cm diameter Insight Ribeirao Preto Sao Paulo Brazil)as previously described [12] The animals (119899 = 5) werepretreated with HEVm (200mgkg) or vehicle (1 h before)or diazepan (1mgkg 30min before) and were individuallyplaced in the apparatus After 1min the distance traveled (m)mobility time (s) and number of lines crossedwere registeredover a period of 5min

28 Determination of Inflammatory Markers The edemaindex was calculated as the ratio of wet weight and dry weightof the samples of pancreatic tissue as previously described[10]

To determine myeloperoxidase (MPO) activity pancreasand lung samples were collected and homogenized withpotassium phosphate buffer (50mM pH 60 containing05 hexadecyltrimethylammonium bromide) Aliquots ofthe homogenates were centrifuged (2min 8000timesg 4∘C)and aliquots of the supernatants were incubated with a solu-tion of o-dianisidine hydrochloride (0167mgmL containing0005H2O2)TheMPOactivity wasmeasured kinetically inamicroliter plate scanner (Biotek) at 460 nmover a period of

5min Results were expressed as units of MPO per mg tissue(UMPOmg tissue) UMPOwas considered as the amount ofenzyme that degrades 1mmol of hydrogen peroxidemin [13]

Enzyme-linked immunosorbent assay (ELISA) forinterleukin- (IL-) 6 IL-1120573 and tumor necrosis factor-(TNF-) 120572was carried out in homogenate samples of pancreasand lung according to the manufacturerrsquos instructions (RampDSystems) The results were corrected by the amount oftissue protein and expressed as pg of each cytokinemg ofproteinThe protein content of tissues was determined by theBradford method using the Bio-Rad protein assay reagent

29 Determination of Biochemical Parameters in SerumBiochemical parameters in serum were assessed for eachexperimental group by using specific commercial kits foramylase (Katal Biotechnology Belo Horizonte MG Brazil)lipase (Human do Brasil Sao Paulo SP Brazil) aspar-tate aminotransferase (AST) and alanine aminotransferase(ALT) (Liquiform Labtest Lagoa Santa MG Brazil) accord-ing to each manufacturerrsquos instructions

210 Determination of Antioxidant Activity Samples of pan-creas and lungwere homogenized in phosphate buffer 50mMpH 70 centrifuged at 10000timesg and the supernatant wasused for all antioxidant assays

Lipid peroxidation was determined by the presence ofthiobarbituric acid reactive substances in samples of pancreasand lung homogenates by the method previously describedby Bose et al [14] with minor modifications [10] The resultswere expressed as pmol of malondialdehyde (MDA) formedper mg of protein

Pancreatic and lung nonprotein sulfhydryl groups (NP-SH) were determined by Ellmanrsquos reaction using 5101584051015840-dithio-bis-2-nitrobenzoic acid as previously described [15] Resultswere expressed as 120583g of NP-SHmg of protein

The determination of oxidized protein content (carbonylgroups) was performed [16] by the reaction of carbonylgroups and 24-dinitrophenylhydrazine The concentrationof carbonyl groups was calculated by using 215mMminus1 cmminus1as the extinction coefficient for aliphatic hydrazones and theresults were expressed as nmol of carbonylsmg of protein

Tissue antioxidant status was evaluated in the homoge-nate of pancreas and lung tissues using the ferric reducingantioxidant power (FRAP) assay [17] Results were plottedagainst a standard curve of ferrous sulphate (500ndash1500120583molL) and were expressed as 120583mol of ferrous sulphatemg ofprotein

Catalase (CAT) activity was appraised by the decrease inabsorption of H2O2 at 240 nm due to H2O2 consumptionby CAT as previously described [18] Specific activity wasexpressed as units of CATmg of protein

The activity of CuZn SODwas assayed by the adrenalinemethod based on the capacity of SOD to inhibit autoxidationof adrenaline to adrenochrome One unit of SOD activity wasdefined as the amount of protein causing 50 inhibition ofthe autoxidation of adrenaline at 26∘C [19]

Glutathione peroxidase (GSH-Px) activity was deter-mined as described previously [20] Enzyme activity was

31 Phytochemical Analysis of HEVm Figure 1 shows theHPLC-DAD chromatograms of the HEVm extract andthe respective identification of the compounds by LC-ESI-MSMS is shown in Table 1 Seven compoundswere identified(three flavan-3-ols one flavonol and three anthocyanins)The major compounds were catechin and epicatechin (Fig-ure 1(a) peaks 1 and 2 119898119911 291) The main anthocyaninswere cyanidin-3-O-glucoside (119898119911 449 peak 6 Figure 1(b))followed by cyanidin-coumaroyl-hexoside (119898119911 595 peak7 Figure 1(b)) both with characteristic molecular ions ofcyanidin (119898119911 287) The total flavonoids content in pow-dered cranberry was 87565mg100 g where flavan-3-ol con-tributed 933 followed by flavonol (43) and anthocyanins(24)

32 Effect of HEVm on Inflammatory Parameters Pancreaticinflammation induced by L-arginine was characterized by amarked increase of pancreatic MPO activity after 72 h Thetreatment with HEVm at 200mgkg prevented this effect(119901 lt 0001) (Figure 2(a)) In addition the inductionof pancreatitis significantly increased MPO activity in thelung tissue compared with the saline group This effect wasalso reduced by the treatment with HEVm at 200mgkg(119901 lt 0001 Figure 2(b)) L-arginine administration enhancedpancreatic edema index after injection (515 plusmn 005 119901 lt0001) compared with the saline group (439 plusmn 008) and thetreatment with HEVm at 200mgkg produced a significantinhibition of this effect (438 plusmn 008 119901 lt 0001) as diddexamethasone (438 plusmn 009 119901 lt 0001) However thetreatment with HEVm at 50 or 100mgkg did not alter edema(514 plusmn 014 492 plusmn 014 resp)

In addition to the increase of the above-mentionedinflammatory parameters the levels of TNF-120572 IL-1120573 andIL-6 were significantly increased in pancreas and lung afterAP induction by L-arginine (Figures 3(a)ndash3(f)) comparedwith animals injected with saline The treatment with HEVmstrongly modulated the levels of these cytokines Levels ofTNF-120572 were significantly decreased by the treatment withHEVm in the pancreatic (119901 lt 001 and 119901 lt 005 respat 100 and 200mgkg Figure 3(a)) and lung tissue (119901 lt0001 at 50 100 and 200mgkg Figure 3(b)) compared

Figure 2 Effect of the hydroethanolic extract of fruits of Vaccinium macrocarpon (HEVm) on pancreatic and lung myeloperoxidase (MPO)activityMicewere submitted to injection of L-arginine or saline treatedwithHEVm (50 100 or 200mgkg) dexamethasone (Dexa 5mgkg)or vehicle (saline) and euthanized after pancreatitis induction MPO activity was measured in pancreas (a) and lung (b) tissues (119899 = 5-6)119901 lt 0001 versus vehicle + saline and lowast119901 lt 005 or lowastlowastlowast119901 lt 0001 versus vehicle + L-arginine One-way ANOVA followed by Bonferronirsquostest

with vehicle-treated animals The amount of IL-1120573 was alsolower in pancreas (119901 lt 001 at 50 and 200mgkg and119901 lt 0001 at 100mgkg Figure 3(c)) and lung tissues(119901 lt 0001 Figure 3(d)) in the group treated with HEVmcompared to the vehicle-treated animals A similar effect wasobserved for IL-6 levels for which the groups treated withHEVm presented significantly lower levels of this cytokinein pancreas (119901 lt 0001 Figure 3(e)) and lung (119901 lt0001 Figure 3(f)) compared with vehicle-treated animalsAs a control treatment with dexamethasone decreased thelevels of these cytokines in both pancreas and lungs tissues(Figure 3)

33 Effect of HEVm on Mechanical Abdominal Hyperalge-sia L-arginine-induced AP was accompanied by a markedreduction of the intensity of stimulus needed to causewithdrawal behavior in mice after 48 or 72 h denoting thatmice developed abdominal hyperalgesia as a consequence ofthe pancreatic inflammation Two-way ANOVA indicated asignificant interaction between the time and treatment in thisexperiment (119901 lt 0001 F = 3712) The injection of salineinstead of L-arginine did not alter the micersquos withdrawalbehavior (Figure 4) in comparison to basal evaluation

Figure 4 also demonstrates that the treatmentwithHEVmclearly reduced the abdominal hyperalgesia of mice submit-ted to AP after 48 h (119901 lt 001 at 50mgkg and 119901 lt 005at 100mgkg) or 72 h (119901 lt 0001 at 50mgkg 119901 lt 001 at100mgkg and 119901 lt 005 at 200mgkg)

As an experimental control treatment with morphineinhibited abdominal hyperalgesia stimulus at 24 (97 plusmn 1 g119901 lt 0001) 48 (83 plusmn 2 g 119901 lt 0001) and 72 h (58 plusmn 2 g119901 lt 0001) after induction of pancreatitis compared withanimals treated with the vehicle (minus37 plusmn 1 minus81 plusmn 1 andminus101 plusmn 1 g resp at 24 48 and 72 h after AP)

34 Lack of Effect of HEVm on the Locomotor ActivityPretreatment of mice (119899 = 5) with HEVm (200mgkg) didnot modify the distance traveled (343plusmn31m) mobility time(258 plusmn 17 s) or the number of lines crossed (238 plusmn 17) whencompared to the vehicle group (363 plusmn 41m 275 plusmn 9 s and245 plusmn 20 resp) As a control pretreatment with diazepandecreased these parameters significantly (84plusmn36m 17plusmn5 sand 13 plusmn 3 119901 lt 0001 each) in comparison to the vehicle-treated group

35 Effect of HEVm on Serum Biochemical Parameters L-arginine-induced AP significantly increased the serum levelsof amylase and lipase This effect was accompanied byincrease of the serum concentrations of ALT and AST afterthe induction of AP compared with saline-injected animalsTreatment with HEVm reduced the serum levels of amylase(200mgkg 119901 lt 0001) lipase (200mgkg 119901 lt 001) ALT(100mgkg 119901 lt 005 200mgkg 119901 lt 005) and AST(100mgkg 119901 lt 005 200mgkg 119901 lt 001) Treatment withdexamethasone (5mgkg) decreased the levels of amylase(119901 lt 001) and lipase (119901 lt 005) in serum (Table 2)

In addition pancreatic and lung nonprotein sulfhydrylgroups (NP-SH) were decreased by AP induction (Figures5(e) and 5(f)) Treatment with HEVm at the doses of 100and 200mgkg maintained the NP-SH content in pancreas(119901 lt 005 Figure 5(e)) and lung (119901 lt 0001 Figure 5(f))compared with animals treated with the vehicle

Additionally tissue antioxidant status was measured inthe pancreas and lung through the determination of thetotal antioxidant activity by the reduction of iron (FRAP)Figures 5(g) and 5(h) demonstrate that tissue antioxidantcapacity was significantly reduced in pancreas and lung afterAP induction and the treatment with 200mgkg of HEVmmaintained this capacity near the levels observed in animals

from the vehicle + saline group in both pancreas (119901 lt 005Figure 5(g)) and lung (119901 lt 0001 Figure 5(h))

Since the treatment with HEVm produced a markedantioxidant effect in pancreas and lung tissue of animals withpancreatitis the contribution of some antioxidant enzymesto this action was studied The induction of AP reducedthe activity of CAT SOD and GSH-Px enzymes in pancreasand CAT and SOD activities in lung (Figure 6) Figure 6(a)shows the increase in pancreatic CAT activity of mice treatedwith HEVm at doses of 50mgkg (119901 lt 001) 100mgkg(119901 lt 0001) and 200mgkg (119901 lt 001) A similar effectwas observed in lungs (Figure 6(b)) of animals treated withHEVm at doses of 50 (119901 lt 005) 100 (119901 lt 001) and

4 Discussion

The need for new experimental alternatives to treat AP isstill a challenge since there are no specific treatments forclinical management of this disease [3] In this study wepresent data that demonstrates that HEVm can modulatethe inflammatory response in pancreas and lung (with theparticipation of oxidative stress) and abdominal hyperalgesiaduring L-arginine-induced AP The finding that HEVm hasbeneficial effect in experimental pancreatitis is novel forthis extract which is frequently used by people to treatinflammatory conditions of the urinary system [8] Howeverthe presence of flavonoids in this extract supports the pos-sibility of a beneficial effect on AP For this reason we usedthe hydroethanolic extract of cranberry Our current datareinforce this hypothesis in themodel of pancreatitis inducedby L-arginine

The phytochemical analysis of HEVm showed that cat-echins and epicatechins are its major components It waspossible to identify three flavan-3-ols one flavonol andthree anthocyanins Catechin epicatechins and cyanidinderivatives were previously described in cranberry prepara-tions [21 22] as was quercetin-3-O-rutinoside (rutin) [23]These compounds exert various biological effects includingantioxidant and anti-inflammatory effects [11 21]

Treatment with HEVm induced protective effects againstpancreatic inflammation The activity of MPO edema indexand production of cytokines (TNF-120572 IL-1120573 and IL-6) werereduced by this extract Along with the lower pancreaticdamage in animals treated with HEVm the levels of serumamylase and lipase were lower which corroborates thereduction of pancreatic damage Neutrophil infiltration isa hallmark of AP [24] and our data show that HEVm caninterfere with the presence of these cells in the pancreasThisagrees with previous findings that cranberry extract reducesthe MPO activity in mice paws injected with carrageenan[23] Similarly treatment with 15 dried whole cranberrypowder (incorporated in the diet) reduced MPO activity inthe colon of mice submitted to dextran sulphate sodium-induced colitis [25] Altogether these results highlight theanti-inflammatory effect of the extract of fruits of V macro-carpon In accordance with this effect treatment with HEVmproduced antiedematogenic effect Corroborating this find-ing [23] showed that the extract of V macrocarpon fruitsreduces the production of prostaglandins in vitro possessesantioxidant activity and inhibits carrageenan-induced micepaw edema The reduction of neutrophil migration to thepancreas and edema formation induced by HEVm certainlyare dependent on the inhibitory activity of proinflammatorycytokines Our results demonstrate that pancreatic contentsof TNF-120572 IL-1120573 and IL-6were reduced by the treatmentwithHEVmOther studies have also demonstrated that the extractof cranberry inhibited IL-6 IL-8 and prostaglandin E2 pro-duction by gingival fibroblasts stimulated with lipopolysac-charide in vitro [26] and that serum IL-1120573 and interferon-120574 concentrations and TNF-120572 and IL-1120573 mRNA expressionin colon were reduced by treatment with cranberry inmice submitted to dextran sulphate sodium-induced colitis[25]

Besides pancreatic inflammation abdominal hyperalge-sia was observed 48 and 72 hours after pancreatitis inductionSimilar results were described by Abreu et al [11] in themodel of L-arginine-induced pancreatitis and we believethat this mimics the abdominal pain observed in humansafter an AP attack The reduction of AP-induced abdom-inal hyperalgesia by the treatment with HEVm may be aconsequence of the decrease of pancreatic inflammatorymediators such as TNF-120572 IL-1120573 and IL-6 However wecannot discard the possibility that substances present inHEVm blocked the stimulation of nociceptive pathwaysSince HEVm administration did not alter the locomotoractivity of mice we can exclude the possibility of muscularrelaxation or central nervous system depression that couldbias the nociceptive measurement Few studies have focusedon the possible analgesic effect of V macrocarpon fruits Arandomized clinical study demonstrated that men receivingradiation therapy for prostate cancer and taking cranberrycapsules presented lower incidence of pain and burning[27] The presence of flavonoids could also contribute tothis antihyperalgesic effect A previous study showed thatthe extract of grapefruit rich in proanthocyanidin (a classof flavonoids) reduced nociception caused by sciatic nerveligation-induced neuropathic pain in rats [28] In additionthe grapefruit extract reduced the nociception induced byformalin in mice by mechanisms involving the participationof opioid receptor activation [29] Concordantly a previousstudy by our group showed that rutin reduced abdominalhyperalgesia in L-arginine-induced pancreatitis in mice [11]

Following AP induction many extrapancreatic responseswere observed in animals injected with L-arginine such asthe increased MPO activity in lung and increased markersof hepatic injury Although the mechanisms underlyingthese alterations are not well understood in this modelof pancreatitis the beneficial effect of HEVm is supportedby these results Serum ALT and AST levels were used asmarkers of extrapancreatic alterations in the present studyThe increase in ALT but not AST is usually predictiveof biliary pancreatitis [30] However in the model of L-arginine-induced AP in rats other authors have shown thatboth AST and ALT are increased [31] but no study haspreviously measured these enzymes in mice Interestinglythis increase in hepatic enzymes was partially reduced by theadministration of HEVm which may in part be due to thereduction of pancreatic lesions as observed by the decreaseof pancreatic inflammatory markers and enzymes (amylaseand lipase)

Lung injury is the secondary effect of pancreatitismost related to mortality in patients [32] In the modelof L-arginine-induced pancreatitis lung MPO activity wasincreased 72 h after induction corroborating previous find-ings [9] The fact that the treatment with HEVm reducedlungMPOactivity is complementary to the above-mentionedextrapancreatic protective effects which might be a conse-quence of the reduction of pancreatic damage Pancreatitis-related lung injury is multifactorial and is associated withmany factors such as the presence of activated enzymesdestruction of the lung surfactant low lung perfusion ratesand increased cytokine in lung tissue [33] Interestingly

Evidence-Based Complementary and Alternative Medicine 11

in agreement with the decrease in lung MPO activity wedetected lower TNF-120572 IL-1120573 and IL-6 levels in lungs ofanimals treated with HEVm in comparison to the vehicle-treated group

Since theHEVm is rich in flavanols and other polyphenolsand these compounds have antioxidant effects [11 34 35] wespeculated that the beneficial actions observed in pancreaticand extrapancreatic parameters could take place with theinvolvement of antioxidant activity In fact increased TBARSand carbonyl groups in parallel with decreased NP-SH andtotal antioxidant capacity (FRAP) in both pancreas and lungindicated that oxidative stress plays a significant role inthis model as previously shown [11 36] Treatment withHEVm maintained antioxidant capacity of the tissue (NP-SH and FRAP) and consequently reduced the oxidationmarkers (MDA and carbonyl) which can be attributedto the direct antioxidant effect of polyphenols found inHEVm [11 22 23 34 37] Another reasonable possibility ofexplaining the antioxidant effect of HEVm is modulation ofthe activity of endogenous antioxidant enzymes Pancreatitisinduction was characterized by reduction of the activity ofCAT SOD and GPx in pancreas and lung corroboratingprevious findings [11] The CAT and SOD activities weremarkedly altered by the treatment with HEVm indicatingthat HEVm strongly modulates oxidative stress InterestinglyCAT and SOD activities seemed to be more susceptible toreversion in pancreas than in lung which agrees with theidea that the reduction of pancreatic damage was importantto the modulation of extrapancreatic effects The beneficialmodulation of CAT and SOD activities in animals treatedwith HEVm was more evident than GPx activity whichwas not altered by treatment with HEVm Indeed HEVmcountered the L-arginine-induced increase in oxidation anddecrease in antioxidative capacity

The antioxidant effects observed in the treatment withHEVm can be caused by the compounds present in thisextract The phenolic compounds found in HEVm likeanthocyanins rutin catechin and epicatechins and otherphenolic compounds (eg quercetin kaempferol ellagicacid and p-coumaric acid) are present in cranberries (forreview see [21 22]) and certainly contributed to the reductionof oxidative stress which in turn decreased the pancreaticlesions and resulted in less severe extrapancreatic alterationsin mice

An important concern about cranberry extracts is regard-ing their safety Many studies have found no toxicity aftertreatment with cranberry extracts for 6ndash10 weeks in exper-imental animals [5 6 38] or in humans [39 40] but arecent study found small differences in the spleen and kidneyfunction of the progeny ofmice treatedwith cranberry extractduring pregnancy [41]Thusmore specific studies are neededto assure the safety of cranberry extracts

Altogether our results indicate a protective role of HEVmin the model of AP induced by L-arginine by reducing pan-creatic damage hyperalgesia and remote alterations throughthe key participation of the antioxidant capacity of thisextract These findings provide insights into the possible useof this extract in the treatment of this disease

31 Phytochemical Analysis of HEVm Figure 1 shows theHPLC-DAD chromatograms of the HEVm extract andthe respective identification of the compounds by LC-ESI-MSMS is shown in Table 1 Seven compoundswere identified(three flavan-3-ols one flavonol and three anthocyanins)The major compounds were catechin and epicatechin (Fig-ure 1(a) peaks 1 and 2 119898119911 291) The main anthocyaninswere cyanidin-3-O-glucoside (119898119911 449 peak 6 Figure 1(b))followed by cyanidin-coumaroyl-hexoside (119898119911 595 peak7 Figure 1(b)) both with characteristic molecular ions ofcyanidin (119898119911 287) The total flavonoids content in pow-dered cranberry was 87565mg100 g where flavan-3-ol con-tributed 933 followed by flavonol (43) and anthocyanins(24)

32 Effect of HEVm on Inflammatory Parameters Pancreaticinflammation induced by L-arginine was characterized by amarked increase of pancreatic MPO activity after 72 h Thetreatment with HEVm at 200mgkg prevented this effect(119901 lt 0001) (Figure 2(a)) In addition the inductionof pancreatitis significantly increased MPO activity in thelung tissue compared with the saline group This effect wasalso reduced by the treatment with HEVm at 200mgkg(119901 lt 0001 Figure 2(b)) L-arginine administration enhancedpancreatic edema index after injection (515 plusmn 005 119901 lt0001) compared with the saline group (439 plusmn 008) and thetreatment with HEVm at 200mgkg produced a significantinhibition of this effect (438 plusmn 008 119901 lt 0001) as diddexamethasone (438 plusmn 009 119901 lt 0001) However thetreatment with HEVm at 50 or 100mgkg did not alter edema(514 plusmn 014 492 plusmn 014 resp)

In addition to the increase of the above-mentionedinflammatory parameters the levels of TNF-120572 IL-1120573 andIL-6 were significantly increased in pancreas and lung afterAP induction by L-arginine (Figures 3(a)ndash3(f)) comparedwith animals injected with saline The treatment with HEVmstrongly modulated the levels of these cytokines Levels ofTNF-120572 were significantly decreased by the treatment withHEVm in the pancreatic (119901 lt 001 and 119901 lt 005 respat 100 and 200mgkg Figure 3(a)) and lung tissue (119901 lt0001 at 50 100 and 200mgkg Figure 3(b)) compared

Figure 2 Effect of the hydroethanolic extract of fruits of Vaccinium macrocarpon (HEVm) on pancreatic and lung myeloperoxidase (MPO)activityMicewere submitted to injection of L-arginine or saline treatedwithHEVm (50 100 or 200mgkg) dexamethasone (Dexa 5mgkg)or vehicle (saline) and euthanized after pancreatitis induction MPO activity was measured in pancreas (a) and lung (b) tissues (119899 = 5-6)119901 lt 0001 versus vehicle + saline and lowast119901 lt 005 or lowastlowastlowast119901 lt 0001 versus vehicle + L-arginine One-way ANOVA followed by Bonferronirsquostest

with vehicle-treated animals The amount of IL-1120573 was alsolower in pancreas (119901 lt 001 at 50 and 200mgkg and119901 lt 0001 at 100mgkg Figure 3(c)) and lung tissues(119901 lt 0001 Figure 3(d)) in the group treated with HEVmcompared to the vehicle-treated animals A similar effect wasobserved for IL-6 levels for which the groups treated withHEVm presented significantly lower levels of this cytokinein pancreas (119901 lt 0001 Figure 3(e)) and lung (119901 lt0001 Figure 3(f)) compared with vehicle-treated animalsAs a control treatment with dexamethasone decreased thelevels of these cytokines in both pancreas and lungs tissues(Figure 3)

33 Effect of HEVm on Mechanical Abdominal Hyperalge-sia L-arginine-induced AP was accompanied by a markedreduction of the intensity of stimulus needed to causewithdrawal behavior in mice after 48 or 72 h denoting thatmice developed abdominal hyperalgesia as a consequence ofthe pancreatic inflammation Two-way ANOVA indicated asignificant interaction between the time and treatment in thisexperiment (119901 lt 0001 F = 3712) The injection of salineinstead of L-arginine did not alter the micersquos withdrawalbehavior (Figure 4) in comparison to basal evaluation

Figure 4 also demonstrates that the treatmentwithHEVmclearly reduced the abdominal hyperalgesia of mice submit-ted to AP after 48 h (119901 lt 001 at 50mgkg and 119901 lt 005at 100mgkg) or 72 h (119901 lt 0001 at 50mgkg 119901 lt 001 at100mgkg and 119901 lt 005 at 200mgkg)

As an experimental control treatment with morphineinhibited abdominal hyperalgesia stimulus at 24 (97 plusmn 1 g119901 lt 0001) 48 (83 plusmn 2 g 119901 lt 0001) and 72 h (58 plusmn 2 g119901 lt 0001) after induction of pancreatitis compared withanimals treated with the vehicle (minus37 plusmn 1 minus81 plusmn 1 andminus101 plusmn 1 g resp at 24 48 and 72 h after AP)

Of interest no difference was observed in the mean basalvalues of intensity of stimulus needed to induce withdrawalbehavior among the groups (saline + vehicle 259 plusmn 20 gL-arginine + vehicle 282 plusmn 07 g L-arginine + HEVm[50mgkg] 265 plusmn 10 g L-arginine + HEVm [100mgkg]261 plusmn 03 g L-arginine + HEVm [200mgkg] 280 plusmn 08 gand L-arginine + morphine 271 plusmn 06 g)

34 Lack of Effect of HEVm on the Locomotor ActivityPretreatment of mice (119899 = 5) with HEVm (200mgkg) didnot modify the distance traveled (343plusmn31m) mobility time(258 plusmn 17 s) or the number of lines crossed (238 plusmn 17) whencompared to the vehicle group (363 plusmn 41m 275 plusmn 9 s and245 plusmn 20 resp) As a control pretreatment with diazepandecreased these parameters significantly (84plusmn36m 17plusmn5 sand 13 plusmn 3 119901 lt 0001 each) in comparison to the vehicle-treated group

35 Effect of HEVm on Serum Biochemical Parameters L-arginine-induced AP significantly increased the serum levelsof amylase and lipase This effect was accompanied byincrease of the serum concentrations of ALT and AST afterthe induction of AP compared with saline-injected animalsTreatment with HEVm reduced the serum levels of amylase(200mgkg 119901 lt 0001) lipase (200mgkg 119901 lt 001) ALT(100mgkg 119901 lt 005 200mgkg 119901 lt 005) and AST(100mgkg 119901 lt 005 200mgkg 119901 lt 001) Treatment withdexamethasone (5mgkg) decreased the levels of amylase(119901 lt 001) and lipase (119901 lt 005) in serum (Table 2)

In addition pancreatic and lung nonprotein sulfhydrylgroups (NP-SH) were decreased by AP induction (Figures5(e) and 5(f)) Treatment with HEVm at the doses of 100and 200mgkg maintained the NP-SH content in pancreas(119901 lt 005 Figure 5(e)) and lung (119901 lt 0001 Figure 5(f))compared with animals treated with the vehicle

Additionally tissue antioxidant status was measured inthe pancreas and lung through the determination of thetotal antioxidant activity by the reduction of iron (FRAP)Figures 5(g) and 5(h) demonstrate that tissue antioxidantcapacity was significantly reduced in pancreas and lung afterAP induction and the treatment with 200mgkg of HEVmmaintained this capacity near the levels observed in animals

from the vehicle + saline group in both pancreas (119901 lt 005Figure 5(g)) and lung (119901 lt 0001 Figure 5(h))

Since the treatment with HEVm produced a markedantioxidant effect in pancreas and lung tissue of animals withpancreatitis the contribution of some antioxidant enzymesto this action was studied The induction of AP reducedthe activity of CAT SOD and GSH-Px enzymes in pancreasand CAT and SOD activities in lung (Figure 6) Figure 6(a)shows the increase in pancreatic CAT activity of mice treatedwith HEVm at doses of 50mgkg (119901 lt 001) 100mgkg(119901 lt 0001) and 200mgkg (119901 lt 001) A similar effectwas observed in lungs (Figure 6(b)) of animals treated withHEVm at doses of 50 (119901 lt 005) 100 (119901 lt 001) and

4 Discussion

The need for new experimental alternatives to treat AP isstill a challenge since there are no specific treatments forclinical management of this disease [3] In this study wepresent data that demonstrates that HEVm can modulatethe inflammatory response in pancreas and lung (with theparticipation of oxidative stress) and abdominal hyperalgesiaduring L-arginine-induced AP The finding that HEVm hasbeneficial effect in experimental pancreatitis is novel forthis extract which is frequently used by people to treatinflammatory conditions of the urinary system [8] Howeverthe presence of flavonoids in this extract supports the pos-sibility of a beneficial effect on AP For this reason we usedthe hydroethanolic extract of cranberry Our current datareinforce this hypothesis in themodel of pancreatitis inducedby L-arginine

The phytochemical analysis of HEVm showed that cat-echins and epicatechins are its major components It waspossible to identify three flavan-3-ols one flavonol andthree anthocyanins Catechin epicatechins and cyanidinderivatives were previously described in cranberry prepara-tions [21 22] as was quercetin-3-O-rutinoside (rutin) [23]These compounds exert various biological effects includingantioxidant and anti-inflammatory effects [11 21]

Treatment with HEVm induced protective effects againstpancreatic inflammation The activity of MPO edema indexand production of cytokines (TNF-120572 IL-1120573 and IL-6) werereduced by this extract Along with the lower pancreaticdamage in animals treated with HEVm the levels of serumamylase and lipase were lower which corroborates thereduction of pancreatic damage Neutrophil infiltration isa hallmark of AP [24] and our data show that HEVm caninterfere with the presence of these cells in the pancreasThisagrees with previous findings that cranberry extract reducesthe MPO activity in mice paws injected with carrageenan[23] Similarly treatment with 15 dried whole cranberrypowder (incorporated in the diet) reduced MPO activity inthe colon of mice submitted to dextran sulphate sodium-induced colitis [25] Altogether these results highlight theanti-inflammatory effect of the extract of fruits of V macro-carpon In accordance with this effect treatment with HEVmproduced antiedematogenic effect Corroborating this find-ing [23] showed that the extract of V macrocarpon fruitsreduces the production of prostaglandins in vitro possessesantioxidant activity and inhibits carrageenan-induced micepaw edema The reduction of neutrophil migration to thepancreas and edema formation induced by HEVm certainlyare dependent on the inhibitory activity of proinflammatorycytokines Our results demonstrate that pancreatic contentsof TNF-120572 IL-1120573 and IL-6were reduced by the treatmentwithHEVmOther studies have also demonstrated that the extractof cranberry inhibited IL-6 IL-8 and prostaglandin E2 pro-duction by gingival fibroblasts stimulated with lipopolysac-charide in vitro [26] and that serum IL-1120573 and interferon-120574 concentrations and TNF-120572 and IL-1120573 mRNA expressionin colon were reduced by treatment with cranberry inmice submitted to dextran sulphate sodium-induced colitis[25]

Besides pancreatic inflammation abdominal hyperalge-sia was observed 48 and 72 hours after pancreatitis inductionSimilar results were described by Abreu et al [11] in themodel of L-arginine-induced pancreatitis and we believethat this mimics the abdominal pain observed in humansafter an AP attack The reduction of AP-induced abdom-inal hyperalgesia by the treatment with HEVm may be aconsequence of the decrease of pancreatic inflammatorymediators such as TNF-120572 IL-1120573 and IL-6 However wecannot discard the possibility that substances present inHEVm blocked the stimulation of nociceptive pathwaysSince HEVm administration did not alter the locomotoractivity of mice we can exclude the possibility of muscularrelaxation or central nervous system depression that couldbias the nociceptive measurement Few studies have focusedon the possible analgesic effect of V macrocarpon fruits Arandomized clinical study demonstrated that men receivingradiation therapy for prostate cancer and taking cranberrycapsules presented lower incidence of pain and burning[27] The presence of flavonoids could also contribute tothis antihyperalgesic effect A previous study showed thatthe extract of grapefruit rich in proanthocyanidin (a classof flavonoids) reduced nociception caused by sciatic nerveligation-induced neuropathic pain in rats [28] In additionthe grapefruit extract reduced the nociception induced byformalin in mice by mechanisms involving the participationof opioid receptor activation [29] Concordantly a previousstudy by our group showed that rutin reduced abdominalhyperalgesia in L-arginine-induced pancreatitis in mice [11]

Following AP induction many extrapancreatic responseswere observed in animals injected with L-arginine such asthe increased MPO activity in lung and increased markersof hepatic injury Although the mechanisms underlyingthese alterations are not well understood in this modelof pancreatitis the beneficial effect of HEVm is supportedby these results Serum ALT and AST levels were used asmarkers of extrapancreatic alterations in the present studyThe increase in ALT but not AST is usually predictiveof biliary pancreatitis [30] However in the model of L-arginine-induced AP in rats other authors have shown thatboth AST and ALT are increased [31] but no study haspreviously measured these enzymes in mice Interestinglythis increase in hepatic enzymes was partially reduced by theadministration of HEVm which may in part be due to thereduction of pancreatic lesions as observed by the decreaseof pancreatic inflammatory markers and enzymes (amylaseand lipase)

Lung injury is the secondary effect of pancreatitismost related to mortality in patients [32] In the modelof L-arginine-induced pancreatitis lung MPO activity wasincreased 72 h after induction corroborating previous find-ings [9] The fact that the treatment with HEVm reducedlungMPOactivity is complementary to the above-mentionedextrapancreatic protective effects which might be a conse-quence of the reduction of pancreatic damage Pancreatitis-related lung injury is multifactorial and is associated withmany factors such as the presence of activated enzymesdestruction of the lung surfactant low lung perfusion ratesand increased cytokine in lung tissue [33] Interestingly

in agreement with the decrease in lung MPO activity wedetected lower TNF-120572 IL-1120573 and IL-6 levels in lungs ofanimals treated with HEVm in comparison to the vehicle-treated group

Since theHEVm is rich in flavanols and other polyphenolsand these compounds have antioxidant effects [11 34 35] wespeculated that the beneficial actions observed in pancreaticand extrapancreatic parameters could take place with theinvolvement of antioxidant activity In fact increased TBARSand carbonyl groups in parallel with decreased NP-SH andtotal antioxidant capacity (FRAP) in both pancreas and lungindicated that oxidative stress plays a significant role inthis model as previously shown [11 36] Treatment withHEVm maintained antioxidant capacity of the tissue (NP-SH and FRAP) and consequently reduced the oxidationmarkers (MDA and carbonyl) which can be attributedto the direct antioxidant effect of polyphenols found inHEVm [11 22 23 34 37] Another reasonable possibility ofexplaining the antioxidant effect of HEVm is modulation ofthe activity of endogenous antioxidant enzymes Pancreatitisinduction was characterized by reduction of the activity ofCAT SOD and GPx in pancreas and lung corroboratingprevious findings [11] The CAT and SOD activities weremarkedly altered by the treatment with HEVm indicatingthat HEVm strongly modulates oxidative stress InterestinglyCAT and SOD activities seemed to be more susceptible toreversion in pancreas than in lung which agrees with theidea that the reduction of pancreatic damage was importantto the modulation of extrapancreatic effects The beneficialmodulation of CAT and SOD activities in animals treatedwith HEVm was more evident than GPx activity whichwas not altered by treatment with HEVm Indeed HEVmcountered the L-arginine-induced increase in oxidation anddecrease in antioxidative capacity

The antioxidant effects observed in the treatment withHEVm can be caused by the compounds present in thisextract The phenolic compounds found in HEVm likeanthocyanins rutin catechin and epicatechins and otherphenolic compounds (eg quercetin kaempferol ellagicacid and p-coumaric acid) are present in cranberries (forreview see [21 22]) and certainly contributed to the reductionof oxidative stress which in turn decreased the pancreaticlesions and resulted in less severe extrapancreatic alterationsin mice

An important concern about cranberry extracts is regard-ing their safety Many studies have found no toxicity aftertreatment with cranberry extracts for 6ndash10 weeks in exper-imental animals [5 6 38] or in humans [39 40] but arecent study found small differences in the spleen and kidneyfunction of the progeny ofmice treatedwith cranberry extractduring pregnancy [41]Thusmore specific studies are neededto assure the safety of cranberry extracts

Altogether our results indicate a protective role of HEVmin the model of AP induced by L-arginine by reducing pan-creatic damage hyperalgesia and remote alterations throughthe key participation of the antioxidant capacity of thisextract These findings provide insights into the possible useof this extract in the treatment of this disease

with vehicle-treated animals The amount of IL-1120573 was alsolower in pancreas (119901 lt 001 at 50 and 200mgkg and119901 lt 0001 at 100mgkg Figure 3(c)) and lung tissues(119901 lt 0001 Figure 3(d)) in the group treated with HEVmcompared to the vehicle-treated animals A similar effect wasobserved for IL-6 levels for which the groups treated withHEVm presented significantly lower levels of this cytokinein pancreas (119901 lt 0001 Figure 3(e)) and lung (119901 lt0001 Figure 3(f)) compared with vehicle-treated animalsAs a control treatment with dexamethasone decreased thelevels of these cytokines in both pancreas and lungs tissues(Figure 3)

33 Effect of HEVm on Mechanical Abdominal Hyperalge-sia L-arginine-induced AP was accompanied by a markedreduction of the intensity of stimulus needed to causewithdrawal behavior in mice after 48 or 72 h denoting thatmice developed abdominal hyperalgesia as a consequence ofthe pancreatic inflammation Two-way ANOVA indicated asignificant interaction between the time and treatment in thisexperiment (119901 lt 0001 F = 3712) The injection of salineinstead of L-arginine did not alter the micersquos withdrawalbehavior (Figure 4) in comparison to basal evaluation

Figure 4 also demonstrates that the treatmentwithHEVmclearly reduced the abdominal hyperalgesia of mice submit-ted to AP after 48 h (119901 lt 001 at 50mgkg and 119901 lt 005at 100mgkg) or 72 h (119901 lt 0001 at 50mgkg 119901 lt 001 at100mgkg and 119901 lt 005 at 200mgkg)

In addition pancreatic and lung nonprotein sulfhydrylgroups (NP-SH) were decreased by AP induction (Figures5(e) and 5(f)) Treatment with HEVm at the doses of 100and 200mgkg maintained the NP-SH content in pancreas(119901 lt 005 Figure 5(e)) and lung (119901 lt 0001 Figure 5(f))compared with animals treated with the vehicle

Additionally tissue antioxidant status was measured inthe pancreas and lung through the determination of thetotal antioxidant activity by the reduction of iron (FRAP)Figures 5(g) and 5(h) demonstrate that tissue antioxidantcapacity was significantly reduced in pancreas and lung afterAP induction and the treatment with 200mgkg of HEVmmaintained this capacity near the levels observed in animals

from the vehicle + saline group in both pancreas (119901 lt 005Figure 5(g)) and lung (119901 lt 0001 Figure 5(h))

Since the treatment with HEVm produced a markedantioxidant effect in pancreas and lung tissue of animals withpancreatitis the contribution of some antioxidant enzymesto this action was studied The induction of AP reducedthe activity of CAT SOD and GSH-Px enzymes in pancreasand CAT and SOD activities in lung (Figure 6) Figure 6(a)shows the increase in pancreatic CAT activity of mice treatedwith HEVm at doses of 50mgkg (119901 lt 001) 100mgkg(119901 lt 0001) and 200mgkg (119901 lt 001) A similar effectwas observed in lungs (Figure 6(b)) of animals treated withHEVm at doses of 50 (119901 lt 005) 100 (119901 lt 001) and

4 Discussion

The need for new experimental alternatives to treat AP isstill a challenge since there are no specific treatments forclinical management of this disease [3] In this study wepresent data that demonstrates that HEVm can modulatethe inflammatory response in pancreas and lung (with theparticipation of oxidative stress) and abdominal hyperalgesiaduring L-arginine-induced AP The finding that HEVm hasbeneficial effect in experimental pancreatitis is novel forthis extract which is frequently used by people to treatinflammatory conditions of the urinary system [8] Howeverthe presence of flavonoids in this extract supports the pos-sibility of a beneficial effect on AP For this reason we usedthe hydroethanolic extract of cranberry Our current datareinforce this hypothesis in themodel of pancreatitis inducedby L-arginine

The phytochemical analysis of HEVm showed that cat-echins and epicatechins are its major components It waspossible to identify three flavan-3-ols one flavonol andthree anthocyanins Catechin epicatechins and cyanidinderivatives were previously described in cranberry prepara-tions [21 22] as was quercetin-3-O-rutinoside (rutin) [23]These compounds exert various biological effects includingantioxidant and anti-inflammatory effects [11 21]

Treatment with HEVm induced protective effects againstpancreatic inflammation The activity of MPO edema indexand production of cytokines (TNF-120572 IL-1120573 and IL-6) werereduced by this extract Along with the lower pancreaticdamage in animals treated with HEVm the levels of serumamylase and lipase were lower which corroborates thereduction of pancreatic damage Neutrophil infiltration isa hallmark of AP [24] and our data show that HEVm caninterfere with the presence of these cells in the pancreasThisagrees with previous findings that cranberry extract reducesthe MPO activity in mice paws injected with carrageenan[23] Similarly treatment with 15 dried whole cranberrypowder (incorporated in the diet) reduced MPO activity inthe colon of mice submitted to dextran sulphate sodium-induced colitis [25] Altogether these results highlight theanti-inflammatory effect of the extract of fruits of V macro-carpon In accordance with this effect treatment with HEVmproduced antiedematogenic effect Corroborating this find-ing [23] showed that the extract of V macrocarpon fruitsreduces the production of prostaglandins in vitro possessesantioxidant activity and inhibits carrageenan-induced micepaw edema The reduction of neutrophil migration to thepancreas and edema formation induced by HEVm certainlyare dependent on the inhibitory activity of proinflammatorycytokines Our results demonstrate that pancreatic contentsof TNF-120572 IL-1120573 and IL-6were reduced by the treatmentwithHEVmOther studies have also demonstrated that the extractof cranberry inhibited IL-6 IL-8 and prostaglandin E2 pro-duction by gingival fibroblasts stimulated with lipopolysac-charide in vitro [26] and that serum IL-1120573 and interferon-120574 concentrations and TNF-120572 and IL-1120573 mRNA expressionin colon were reduced by treatment with cranberry inmice submitted to dextran sulphate sodium-induced colitis[25]

Besides pancreatic inflammation abdominal hyperalge-sia was observed 48 and 72 hours after pancreatitis inductionSimilar results were described by Abreu et al [11] in themodel of L-arginine-induced pancreatitis and we believethat this mimics the abdominal pain observed in humansafter an AP attack The reduction of AP-induced abdom-inal hyperalgesia by the treatment with HEVm may be aconsequence of the decrease of pancreatic inflammatorymediators such as TNF-120572 IL-1120573 and IL-6 However wecannot discard the possibility that substances present inHEVm blocked the stimulation of nociceptive pathwaysSince HEVm administration did not alter the locomotoractivity of mice we can exclude the possibility of muscularrelaxation or central nervous system depression that couldbias the nociceptive measurement Few studies have focusedon the possible analgesic effect of V macrocarpon fruits Arandomized clinical study demonstrated that men receivingradiation therapy for prostate cancer and taking cranberrycapsules presented lower incidence of pain and burning[27] The presence of flavonoids could also contribute tothis antihyperalgesic effect A previous study showed thatthe extract of grapefruit rich in proanthocyanidin (a classof flavonoids) reduced nociception caused by sciatic nerveligation-induced neuropathic pain in rats [28] In additionthe grapefruit extract reduced the nociception induced byformalin in mice by mechanisms involving the participationof opioid receptor activation [29] Concordantly a previousstudy by our group showed that rutin reduced abdominalhyperalgesia in L-arginine-induced pancreatitis in mice [11]

Following AP induction many extrapancreatic responseswere observed in animals injected with L-arginine such asthe increased MPO activity in lung and increased markersof hepatic injury Although the mechanisms underlyingthese alterations are not well understood in this modelof pancreatitis the beneficial effect of HEVm is supportedby these results Serum ALT and AST levels were used asmarkers of extrapancreatic alterations in the present studyThe increase in ALT but not AST is usually predictiveof biliary pancreatitis [30] However in the model of L-arginine-induced AP in rats other authors have shown thatboth AST and ALT are increased [31] but no study haspreviously measured these enzymes in mice Interestinglythis increase in hepatic enzymes was partially reduced by theadministration of HEVm which may in part be due to thereduction of pancreatic lesions as observed by the decreaseof pancreatic inflammatory markers and enzymes (amylaseand lipase)

Lung injury is the secondary effect of pancreatitismost related to mortality in patients [32] In the modelof L-arginine-induced pancreatitis lung MPO activity wasincreased 72 h after induction corroborating previous find-ings [9] The fact that the treatment with HEVm reducedlungMPOactivity is complementary to the above-mentionedextrapancreatic protective effects which might be a conse-quence of the reduction of pancreatic damage Pancreatitis-related lung injury is multifactorial and is associated withmany factors such as the presence of activated enzymesdestruction of the lung surfactant low lung perfusion ratesand increased cytokine in lung tissue [33] Interestingly

Evidence-Based Complementary and Alternative Medicine 11

in agreement with the decrease in lung MPO activity wedetected lower TNF-120572 IL-1120573 and IL-6 levels in lungs ofanimals treated with HEVm in comparison to the vehicle-treated group

Since theHEVm is rich in flavanols and other polyphenolsand these compounds have antioxidant effects [11 34 35] wespeculated that the beneficial actions observed in pancreaticand extrapancreatic parameters could take place with theinvolvement of antioxidant activity In fact increased TBARSand carbonyl groups in parallel with decreased NP-SH andtotal antioxidant capacity (FRAP) in both pancreas and lungindicated that oxidative stress plays a significant role inthis model as previously shown [11 36] Treatment withHEVm maintained antioxidant capacity of the tissue (NP-SH and FRAP) and consequently reduced the oxidationmarkers (MDA and carbonyl) which can be attributedto the direct antioxidant effect of polyphenols found inHEVm [11 22 23 34 37] Another reasonable possibility ofexplaining the antioxidant effect of HEVm is modulation ofthe activity of endogenous antioxidant enzymes Pancreatitisinduction was characterized by reduction of the activity ofCAT SOD and GPx in pancreas and lung corroboratingprevious findings [11] The CAT and SOD activities weremarkedly altered by the treatment with HEVm indicatingthat HEVm strongly modulates oxidative stress InterestinglyCAT and SOD activities seemed to be more susceptible toreversion in pancreas than in lung which agrees with theidea that the reduction of pancreatic damage was importantto the modulation of extrapancreatic effects The beneficialmodulation of CAT and SOD activities in animals treatedwith HEVm was more evident than GPx activity whichwas not altered by treatment with HEVm Indeed HEVmcountered the L-arginine-induced increase in oxidation anddecrease in antioxidative capacity

The antioxidant effects observed in the treatment withHEVm can be caused by the compounds present in thisextract The phenolic compounds found in HEVm likeanthocyanins rutin catechin and epicatechins and otherphenolic compounds (eg quercetin kaempferol ellagicacid and p-coumaric acid) are present in cranberries (forreview see [21 22]) and certainly contributed to the reductionof oxidative stress which in turn decreased the pancreaticlesions and resulted in less severe extrapancreatic alterationsin mice

An important concern about cranberry extracts is regard-ing their safety Many studies have found no toxicity aftertreatment with cranberry extracts for 6ndash10 weeks in exper-imental animals [5 6 38] or in humans [39 40] but arecent study found small differences in the spleen and kidneyfunction of the progeny ofmice treatedwith cranberry extractduring pregnancy [41]Thusmore specific studies are neededto assure the safety of cranberry extracts

Altogether our results indicate a protective role of HEVmin the model of AP induced by L-arginine by reducing pan-creatic damage hyperalgesia and remote alterations throughthe key participation of the antioxidant capacity of thisextract These findings provide insights into the possible useof this extract in the treatment of this disease

In addition pancreatic and lung nonprotein sulfhydrylgroups (NP-SH) were decreased by AP induction (Figures5(e) and 5(f)) Treatment with HEVm at the doses of 100and 200mgkg maintained the NP-SH content in pancreas(119901 lt 005 Figure 5(e)) and lung (119901 lt 0001 Figure 5(f))compared with animals treated with the vehicle

Additionally tissue antioxidant status was measured inthe pancreas and lung through the determination of thetotal antioxidant activity by the reduction of iron (FRAP)Figures 5(g) and 5(h) demonstrate that tissue antioxidantcapacity was significantly reduced in pancreas and lung afterAP induction and the treatment with 200mgkg of HEVmmaintained this capacity near the levels observed in animals

from the vehicle + saline group in both pancreas (119901 lt 005Figure 5(g)) and lung (119901 lt 0001 Figure 5(h))

Since the treatment with HEVm produced a markedantioxidant effect in pancreas and lung tissue of animals withpancreatitis the contribution of some antioxidant enzymesto this action was studied The induction of AP reducedthe activity of CAT SOD and GSH-Px enzymes in pancreasand CAT and SOD activities in lung (Figure 6) Figure 6(a)shows the increase in pancreatic CAT activity of mice treatedwith HEVm at doses of 50mgkg (119901 lt 001) 100mgkg(119901 lt 0001) and 200mgkg (119901 lt 001) A similar effectwas observed in lungs (Figure 6(b)) of animals treated withHEVm at doses of 50 (119901 lt 005) 100 (119901 lt 001) and

4 Discussion

The need for new experimental alternatives to treat AP isstill a challenge since there are no specific treatments forclinical management of this disease [3] In this study wepresent data that demonstrates that HEVm can modulatethe inflammatory response in pancreas and lung (with theparticipation of oxidative stress) and abdominal hyperalgesiaduring L-arginine-induced AP The finding that HEVm hasbeneficial effect in experimental pancreatitis is novel forthis extract which is frequently used by people to treatinflammatory conditions of the urinary system [8] Howeverthe presence of flavonoids in this extract supports the pos-sibility of a beneficial effect on AP For this reason we usedthe hydroethanolic extract of cranberry Our current datareinforce this hypothesis in themodel of pancreatitis inducedby L-arginine

The phytochemical analysis of HEVm showed that cat-echins and epicatechins are its major components It waspossible to identify three flavan-3-ols one flavonol andthree anthocyanins Catechin epicatechins and cyanidinderivatives were previously described in cranberry prepara-tions [21 22] as was quercetin-3-O-rutinoside (rutin) [23]These compounds exert various biological effects includingantioxidant and anti-inflammatory effects [11 21]

Treatment with HEVm induced protective effects againstpancreatic inflammation The activity of MPO edema indexand production of cytokines (TNF-120572 IL-1120573 and IL-6) werereduced by this extract Along with the lower pancreaticdamage in animals treated with HEVm the levels of serumamylase and lipase were lower which corroborates thereduction of pancreatic damage Neutrophil infiltration isa hallmark of AP [24] and our data show that HEVm caninterfere with the presence of these cells in the pancreasThisagrees with previous findings that cranberry extract reducesthe MPO activity in mice paws injected with carrageenan[23] Similarly treatment with 15 dried whole cranberrypowder (incorporated in the diet) reduced MPO activity inthe colon of mice submitted to dextran sulphate sodium-induced colitis [25] Altogether these results highlight theanti-inflammatory effect of the extract of fruits of V macro-carpon In accordance with this effect treatment with HEVmproduced antiedematogenic effect Corroborating this find-ing [23] showed that the extract of V macrocarpon fruitsreduces the production of prostaglandins in vitro possessesantioxidant activity and inhibits carrageenan-induced micepaw edema The reduction of neutrophil migration to thepancreas and edema formation induced by HEVm certainlyare dependent on the inhibitory activity of proinflammatorycytokines Our results demonstrate that pancreatic contentsof TNF-120572 IL-1120573 and IL-6were reduced by the treatmentwithHEVmOther studies have also demonstrated that the extractof cranberry inhibited IL-6 IL-8 and prostaglandin E2 pro-duction by gingival fibroblasts stimulated with lipopolysac-charide in vitro [26] and that serum IL-1120573 and interferon-120574 concentrations and TNF-120572 and IL-1120573 mRNA expressionin colon were reduced by treatment with cranberry inmice submitted to dextran sulphate sodium-induced colitis[25]

Besides pancreatic inflammation abdominal hyperalge-sia was observed 48 and 72 hours after pancreatitis inductionSimilar results were described by Abreu et al [11] in themodel of L-arginine-induced pancreatitis and we believethat this mimics the abdominal pain observed in humansafter an AP attack The reduction of AP-induced abdom-inal hyperalgesia by the treatment with HEVm may be aconsequence of the decrease of pancreatic inflammatorymediators such as TNF-120572 IL-1120573 and IL-6 However wecannot discard the possibility that substances present inHEVm blocked the stimulation of nociceptive pathwaysSince HEVm administration did not alter the locomotoractivity of mice we can exclude the possibility of muscularrelaxation or central nervous system depression that couldbias the nociceptive measurement Few studies have focusedon the possible analgesic effect of V macrocarpon fruits Arandomized clinical study demonstrated that men receivingradiation therapy for prostate cancer and taking cranberrycapsules presented lower incidence of pain and burning[27] The presence of flavonoids could also contribute tothis antihyperalgesic effect A previous study showed thatthe extract of grapefruit rich in proanthocyanidin (a classof flavonoids) reduced nociception caused by sciatic nerveligation-induced neuropathic pain in rats [28] In additionthe grapefruit extract reduced the nociception induced byformalin in mice by mechanisms involving the participationof opioid receptor activation [29] Concordantly a previousstudy by our group showed that rutin reduced abdominalhyperalgesia in L-arginine-induced pancreatitis in mice [11]

Following AP induction many extrapancreatic responseswere observed in animals injected with L-arginine such asthe increased MPO activity in lung and increased markersof hepatic injury Although the mechanisms underlyingthese alterations are not well understood in this modelof pancreatitis the beneficial effect of HEVm is supportedby these results Serum ALT and AST levels were used asmarkers of extrapancreatic alterations in the present studyThe increase in ALT but not AST is usually predictiveof biliary pancreatitis [30] However in the model of L-arginine-induced AP in rats other authors have shown thatboth AST and ALT are increased [31] but no study haspreviously measured these enzymes in mice Interestinglythis increase in hepatic enzymes was partially reduced by theadministration of HEVm which may in part be due to thereduction of pancreatic lesions as observed by the decreaseof pancreatic inflammatory markers and enzymes (amylaseand lipase)

Lung injury is the secondary effect of pancreatitismost related to mortality in patients [32] In the modelof L-arginine-induced pancreatitis lung MPO activity wasincreased 72 h after induction corroborating previous find-ings [9] The fact that the treatment with HEVm reducedlungMPOactivity is complementary to the above-mentionedextrapancreatic protective effects which might be a conse-quence of the reduction of pancreatic damage Pancreatitis-related lung injury is multifactorial and is associated withmany factors such as the presence of activated enzymesdestruction of the lung surfactant low lung perfusion ratesand increased cytokine in lung tissue [33] Interestingly

in agreement with the decrease in lung MPO activity wedetected lower TNF-120572 IL-1120573 and IL-6 levels in lungs ofanimals treated with HEVm in comparison to the vehicle-treated group

Since theHEVm is rich in flavanols and other polyphenolsand these compounds have antioxidant effects [11 34 35] wespeculated that the beneficial actions observed in pancreaticand extrapancreatic parameters could take place with theinvolvement of antioxidant activity In fact increased TBARSand carbonyl groups in parallel with decreased NP-SH andtotal antioxidant capacity (FRAP) in both pancreas and lungindicated that oxidative stress plays a significant role inthis model as previously shown [11 36] Treatment withHEVm maintained antioxidant capacity of the tissue (NP-SH and FRAP) and consequently reduced the oxidationmarkers (MDA and carbonyl) which can be attributedto the direct antioxidant effect of polyphenols found inHEVm [11 22 23 34 37] Another reasonable possibility ofexplaining the antioxidant effect of HEVm is modulation ofthe activity of endogenous antioxidant enzymes Pancreatitisinduction was characterized by reduction of the activity ofCAT SOD and GPx in pancreas and lung corroboratingprevious findings [11] The CAT and SOD activities weremarkedly altered by the treatment with HEVm indicatingthat HEVm strongly modulates oxidative stress InterestinglyCAT and SOD activities seemed to be more susceptible toreversion in pancreas than in lung which agrees with theidea that the reduction of pancreatic damage was importantto the modulation of extrapancreatic effects The beneficialmodulation of CAT and SOD activities in animals treatedwith HEVm was more evident than GPx activity whichwas not altered by treatment with HEVm Indeed HEVmcountered the L-arginine-induced increase in oxidation anddecrease in antioxidative capacity

The antioxidant effects observed in the treatment withHEVm can be caused by the compounds present in thisextract The phenolic compounds found in HEVm likeanthocyanins rutin catechin and epicatechins and otherphenolic compounds (eg quercetin kaempferol ellagicacid and p-coumaric acid) are present in cranberries (forreview see [21 22]) and certainly contributed to the reductionof oxidative stress which in turn decreased the pancreaticlesions and resulted in less severe extrapancreatic alterationsin mice

An important concern about cranberry extracts is regard-ing their safety Many studies have found no toxicity aftertreatment with cranberry extracts for 6ndash10 weeks in exper-imental animals [5 6 38] or in humans [39 40] but arecent study found small differences in the spleen and kidneyfunction of the progeny ofmice treatedwith cranberry extractduring pregnancy [41]Thusmore specific studies are neededto assure the safety of cranberry extracts

Altogether our results indicate a protective role of HEVmin the model of AP induced by L-arginine by reducing pan-creatic damage hyperalgesia and remote alterations throughthe key participation of the antioxidant capacity of thisextract These findings provide insights into the possible useof this extract in the treatment of this disease

In addition pancreatic and lung nonprotein sulfhydrylgroups (NP-SH) were decreased by AP induction (Figures5(e) and 5(f)) Treatment with HEVm at the doses of 100and 200mgkg maintained the NP-SH content in pancreas(119901 lt 005 Figure 5(e)) and lung (119901 lt 0001 Figure 5(f))compared with animals treated with the vehicle

Additionally tissue antioxidant status was measured inthe pancreas and lung through the determination of thetotal antioxidant activity by the reduction of iron (FRAP)Figures 5(g) and 5(h) demonstrate that tissue antioxidantcapacity was significantly reduced in pancreas and lung afterAP induction and the treatment with 200mgkg of HEVmmaintained this capacity near the levels observed in animals

from the vehicle + saline group in both pancreas (119901 lt 005Figure 5(g)) and lung (119901 lt 0001 Figure 5(h))

Since the treatment with HEVm produced a markedantioxidant effect in pancreas and lung tissue of animals withpancreatitis the contribution of some antioxidant enzymesto this action was studied The induction of AP reducedthe activity of CAT SOD and GSH-Px enzymes in pancreasand CAT and SOD activities in lung (Figure 6) Figure 6(a)shows the increase in pancreatic CAT activity of mice treatedwith HEVm at doses of 50mgkg (119901 lt 001) 100mgkg(119901 lt 0001) and 200mgkg (119901 lt 001) A similar effectwas observed in lungs (Figure 6(b)) of animals treated withHEVm at doses of 50 (119901 lt 005) 100 (119901 lt 001) and

4 Discussion

The need for new experimental alternatives to treat AP isstill a challenge since there are no specific treatments forclinical management of this disease [3] In this study wepresent data that demonstrates that HEVm can modulatethe inflammatory response in pancreas and lung (with theparticipation of oxidative stress) and abdominal hyperalgesiaduring L-arginine-induced AP The finding that HEVm hasbeneficial effect in experimental pancreatitis is novel forthis extract which is frequently used by people to treatinflammatory conditions of the urinary system [8] Howeverthe presence of flavonoids in this extract supports the pos-sibility of a beneficial effect on AP For this reason we usedthe hydroethanolic extract of cranberry Our current datareinforce this hypothesis in themodel of pancreatitis inducedby L-arginine

The phytochemical analysis of HEVm showed that cat-echins and epicatechins are its major components It waspossible to identify three flavan-3-ols one flavonol andthree anthocyanins Catechin epicatechins and cyanidinderivatives were previously described in cranberry prepara-tions [21 22] as was quercetin-3-O-rutinoside (rutin) [23]These compounds exert various biological effects includingantioxidant and anti-inflammatory effects [11 21]

Treatment with HEVm induced protective effects againstpancreatic inflammation The activity of MPO edema indexand production of cytokines (TNF-120572 IL-1120573 and IL-6) werereduced by this extract Along with the lower pancreaticdamage in animals treated with HEVm the levels of serumamylase and lipase were lower which corroborates thereduction of pancreatic damage Neutrophil infiltration isa hallmark of AP [24] and our data show that HEVm caninterfere with the presence of these cells in the pancreasThisagrees with previous findings that cranberry extract reducesthe MPO activity in mice paws injected with carrageenan[23] Similarly treatment with 15 dried whole cranberrypowder (incorporated in the diet) reduced MPO activity inthe colon of mice submitted to dextran sulphate sodium-induced colitis [25] Altogether these results highlight theanti-inflammatory effect of the extract of fruits of V macro-carpon In accordance with this effect treatment with HEVmproduced antiedematogenic effect Corroborating this find-ing [23] showed that the extract of V macrocarpon fruitsreduces the production of prostaglandins in vitro possessesantioxidant activity and inhibits carrageenan-induced micepaw edema The reduction of neutrophil migration to thepancreas and edema formation induced by HEVm certainlyare dependent on the inhibitory activity of proinflammatorycytokines Our results demonstrate that pancreatic contentsof TNF-120572 IL-1120573 and IL-6were reduced by the treatmentwithHEVmOther studies have also demonstrated that the extractof cranberry inhibited IL-6 IL-8 and prostaglandin E2 pro-duction by gingival fibroblasts stimulated with lipopolysac-charide in vitro [26] and that serum IL-1120573 and interferon-120574 concentrations and TNF-120572 and IL-1120573 mRNA expressionin colon were reduced by treatment with cranberry inmice submitted to dextran sulphate sodium-induced colitis[25]

Besides pancreatic inflammation abdominal hyperalge-sia was observed 48 and 72 hours after pancreatitis inductionSimilar results were described by Abreu et al [11] in themodel of L-arginine-induced pancreatitis and we believethat this mimics the abdominal pain observed in humansafter an AP attack The reduction of AP-induced abdom-inal hyperalgesia by the treatment with HEVm may be aconsequence of the decrease of pancreatic inflammatorymediators such as TNF-120572 IL-1120573 and IL-6 However wecannot discard the possibility that substances present inHEVm blocked the stimulation of nociceptive pathwaysSince HEVm administration did not alter the locomotoractivity of mice we can exclude the possibility of muscularrelaxation or central nervous system depression that couldbias the nociceptive measurement Few studies have focusedon the possible analgesic effect of V macrocarpon fruits Arandomized clinical study demonstrated that men receivingradiation therapy for prostate cancer and taking cranberrycapsules presented lower incidence of pain and burning[27] The presence of flavonoids could also contribute tothis antihyperalgesic effect A previous study showed thatthe extract of grapefruit rich in proanthocyanidin (a classof flavonoids) reduced nociception caused by sciatic nerveligation-induced neuropathic pain in rats [28] In additionthe grapefruit extract reduced the nociception induced byformalin in mice by mechanisms involving the participationof opioid receptor activation [29] Concordantly a previousstudy by our group showed that rutin reduced abdominalhyperalgesia in L-arginine-induced pancreatitis in mice [11]

Following AP induction many extrapancreatic responseswere observed in animals injected with L-arginine such asthe increased MPO activity in lung and increased markersof hepatic injury Although the mechanisms underlyingthese alterations are not well understood in this modelof pancreatitis the beneficial effect of HEVm is supportedby these results Serum ALT and AST levels were used asmarkers of extrapancreatic alterations in the present studyThe increase in ALT but not AST is usually predictiveof biliary pancreatitis [30] However in the model of L-arginine-induced AP in rats other authors have shown thatboth AST and ALT are increased [31] but no study haspreviously measured these enzymes in mice Interestinglythis increase in hepatic enzymes was partially reduced by theadministration of HEVm which may in part be due to thereduction of pancreatic lesions as observed by the decreaseof pancreatic inflammatory markers and enzymes (amylaseand lipase)

Lung injury is the secondary effect of pancreatitismost related to mortality in patients [32] In the modelof L-arginine-induced pancreatitis lung MPO activity wasincreased 72 h after induction corroborating previous find-ings [9] The fact that the treatment with HEVm reducedlungMPOactivity is complementary to the above-mentionedextrapancreatic protective effects which might be a conse-quence of the reduction of pancreatic damage Pancreatitis-related lung injury is multifactorial and is associated withmany factors such as the presence of activated enzymesdestruction of the lung surfactant low lung perfusion ratesand increased cytokine in lung tissue [33] Interestingly

in agreement with the decrease in lung MPO activity wedetected lower TNF-120572 IL-1120573 and IL-6 levels in lungs ofanimals treated with HEVm in comparison to the vehicle-treated group

Since theHEVm is rich in flavanols and other polyphenolsand these compounds have antioxidant effects [11 34 35] wespeculated that the beneficial actions observed in pancreaticand extrapancreatic parameters could take place with theinvolvement of antioxidant activity In fact increased TBARSand carbonyl groups in parallel with decreased NP-SH andtotal antioxidant capacity (FRAP) in both pancreas and lungindicated that oxidative stress plays a significant role inthis model as previously shown [11 36] Treatment withHEVm maintained antioxidant capacity of the tissue (NP-SH and FRAP) and consequently reduced the oxidationmarkers (MDA and carbonyl) which can be attributedto the direct antioxidant effect of polyphenols found inHEVm [11 22 23 34 37] Another reasonable possibility ofexplaining the antioxidant effect of HEVm is modulation ofthe activity of endogenous antioxidant enzymes Pancreatitisinduction was characterized by reduction of the activity ofCAT SOD and GPx in pancreas and lung corroboratingprevious findings [11] The CAT and SOD activities weremarkedly altered by the treatment with HEVm indicatingthat HEVm strongly modulates oxidative stress InterestinglyCAT and SOD activities seemed to be more susceptible toreversion in pancreas than in lung which agrees with theidea that the reduction of pancreatic damage was importantto the modulation of extrapancreatic effects The beneficialmodulation of CAT and SOD activities in animals treatedwith HEVm was more evident than GPx activity whichwas not altered by treatment with HEVm Indeed HEVmcountered the L-arginine-induced increase in oxidation anddecrease in antioxidative capacity

The antioxidant effects observed in the treatment withHEVm can be caused by the compounds present in thisextract The phenolic compounds found in HEVm likeanthocyanins rutin catechin and epicatechins and otherphenolic compounds (eg quercetin kaempferol ellagicacid and p-coumaric acid) are present in cranberries (forreview see [21 22]) and certainly contributed to the reductionof oxidative stress which in turn decreased the pancreaticlesions and resulted in less severe extrapancreatic alterationsin mice

An important concern about cranberry extracts is regard-ing their safety Many studies have found no toxicity aftertreatment with cranberry extracts for 6ndash10 weeks in exper-imental animals [5 6 38] or in humans [39 40] but arecent study found small differences in the spleen and kidneyfunction of the progeny ofmice treatedwith cranberry extractduring pregnancy [41]Thusmore specific studies are neededto assure the safety of cranberry extracts

Altogether our results indicate a protective role of HEVmin the model of AP induced by L-arginine by reducing pan-creatic damage hyperalgesia and remote alterations throughthe key participation of the antioxidant capacity of thisextract These findings provide insights into the possible useof this extract in the treatment of this disease

4 Discussion

The need for new experimental alternatives to treat AP isstill a challenge since there are no specific treatments forclinical management of this disease [3] In this study wepresent data that demonstrates that HEVm can modulatethe inflammatory response in pancreas and lung (with theparticipation of oxidative stress) and abdominal hyperalgesiaduring L-arginine-induced AP The finding that HEVm hasbeneficial effect in experimental pancreatitis is novel forthis extract which is frequently used by people to treatinflammatory conditions of the urinary system [8] Howeverthe presence of flavonoids in this extract supports the pos-sibility of a beneficial effect on AP For this reason we usedthe hydroethanolic extract of cranberry Our current datareinforce this hypothesis in themodel of pancreatitis inducedby L-arginine

The phytochemical analysis of HEVm showed that cat-echins and epicatechins are its major components It waspossible to identify three flavan-3-ols one flavonol andthree anthocyanins Catechin epicatechins and cyanidinderivatives were previously described in cranberry prepara-tions [21 22] as was quercetin-3-O-rutinoside (rutin) [23]These compounds exert various biological effects includingantioxidant and anti-inflammatory effects [11 21]

Treatment with HEVm induced protective effects againstpancreatic inflammation The activity of MPO edema indexand production of cytokines (TNF-120572 IL-1120573 and IL-6) werereduced by this extract Along with the lower pancreaticdamage in animals treated with HEVm the levels of serumamylase and lipase were lower which corroborates thereduction of pancreatic damage Neutrophil infiltration isa hallmark of AP [24] and our data show that HEVm caninterfere with the presence of these cells in the pancreasThisagrees with previous findings that cranberry extract reducesthe MPO activity in mice paws injected with carrageenan[23] Similarly treatment with 15 dried whole cranberrypowder (incorporated in the diet) reduced MPO activity inthe colon of mice submitted to dextran sulphate sodium-induced colitis [25] Altogether these results highlight theanti-inflammatory effect of the extract of fruits of V macro-carpon In accordance with this effect treatment with HEVmproduced antiedematogenic effect Corroborating this find-ing [23] showed that the extract of V macrocarpon fruitsreduces the production of prostaglandins in vitro possessesantioxidant activity and inhibits carrageenan-induced micepaw edema The reduction of neutrophil migration to thepancreas and edema formation induced by HEVm certainlyare dependent on the inhibitory activity of proinflammatorycytokines Our results demonstrate that pancreatic contentsof TNF-120572 IL-1120573 and IL-6were reduced by the treatmentwithHEVmOther studies have also demonstrated that the extractof cranberry inhibited IL-6 IL-8 and prostaglandin E2 pro-duction by gingival fibroblasts stimulated with lipopolysac-charide in vitro [26] and that serum IL-1120573 and interferon-120574 concentrations and TNF-120572 and IL-1120573 mRNA expressionin colon were reduced by treatment with cranberry inmice submitted to dextran sulphate sodium-induced colitis[25]

Besides pancreatic inflammation abdominal hyperalge-sia was observed 48 and 72 hours after pancreatitis inductionSimilar results were described by Abreu et al [11] in themodel of L-arginine-induced pancreatitis and we believethat this mimics the abdominal pain observed in humansafter an AP attack The reduction of AP-induced abdom-inal hyperalgesia by the treatment with HEVm may be aconsequence of the decrease of pancreatic inflammatorymediators such as TNF-120572 IL-1120573 and IL-6 However wecannot discard the possibility that substances present inHEVm blocked the stimulation of nociceptive pathwaysSince HEVm administration did not alter the locomotoractivity of mice we can exclude the possibility of muscularrelaxation or central nervous system depression that couldbias the nociceptive measurement Few studies have focusedon the possible analgesic effect of V macrocarpon fruits Arandomized clinical study demonstrated that men receivingradiation therapy for prostate cancer and taking cranberrycapsules presented lower incidence of pain and burning[27] The presence of flavonoids could also contribute tothis antihyperalgesic effect A previous study showed thatthe extract of grapefruit rich in proanthocyanidin (a classof flavonoids) reduced nociception caused by sciatic nerveligation-induced neuropathic pain in rats [28] In additionthe grapefruit extract reduced the nociception induced byformalin in mice by mechanisms involving the participationof opioid receptor activation [29] Concordantly a previousstudy by our group showed that rutin reduced abdominalhyperalgesia in L-arginine-induced pancreatitis in mice [11]

Following AP induction many extrapancreatic responseswere observed in animals injected with L-arginine such asthe increased MPO activity in lung and increased markersof hepatic injury Although the mechanisms underlyingthese alterations are not well understood in this modelof pancreatitis the beneficial effect of HEVm is supportedby these results Serum ALT and AST levels were used asmarkers of extrapancreatic alterations in the present studyThe increase in ALT but not AST is usually predictiveof biliary pancreatitis [30] However in the model of L-arginine-induced AP in rats other authors have shown thatboth AST and ALT are increased [31] but no study haspreviously measured these enzymes in mice Interestinglythis increase in hepatic enzymes was partially reduced by theadministration of HEVm which may in part be due to thereduction of pancreatic lesions as observed by the decreaseof pancreatic inflammatory markers and enzymes (amylaseand lipase)

Lung injury is the secondary effect of pancreatitismost related to mortality in patients [32] In the modelof L-arginine-induced pancreatitis lung MPO activity wasincreased 72 h after induction corroborating previous find-ings [9] The fact that the treatment with HEVm reducedlungMPOactivity is complementary to the above-mentionedextrapancreatic protective effects which might be a conse-quence of the reduction of pancreatic damage Pancreatitis-related lung injury is multifactorial and is associated withmany factors such as the presence of activated enzymesdestruction of the lung surfactant low lung perfusion ratesand increased cytokine in lung tissue [33] Interestingly

in agreement with the decrease in lung MPO activity wedetected lower TNF-120572 IL-1120573 and IL-6 levels in lungs ofanimals treated with HEVm in comparison to the vehicle-treated group

Since theHEVm is rich in flavanols and other polyphenolsand these compounds have antioxidant effects [11 34 35] wespeculated that the beneficial actions observed in pancreaticand extrapancreatic parameters could take place with theinvolvement of antioxidant activity In fact increased TBARSand carbonyl groups in parallel with decreased NP-SH andtotal antioxidant capacity (FRAP) in both pancreas and lungindicated that oxidative stress plays a significant role inthis model as previously shown [11 36] Treatment withHEVm maintained antioxidant capacity of the tissue (NP-SH and FRAP) and consequently reduced the oxidationmarkers (MDA and carbonyl) which can be attributedto the direct antioxidant effect of polyphenols found inHEVm [11 22 23 34 37] Another reasonable possibility ofexplaining the antioxidant effect of HEVm is modulation ofthe activity of endogenous antioxidant enzymes Pancreatitisinduction was characterized by reduction of the activity ofCAT SOD and GPx in pancreas and lung corroboratingprevious findings [11] The CAT and SOD activities weremarkedly altered by the treatment with HEVm indicatingthat HEVm strongly modulates oxidative stress InterestinglyCAT and SOD activities seemed to be more susceptible toreversion in pancreas than in lung which agrees with theidea that the reduction of pancreatic damage was importantto the modulation of extrapancreatic effects The beneficialmodulation of CAT and SOD activities in animals treatedwith HEVm was more evident than GPx activity whichwas not altered by treatment with HEVm Indeed HEVmcountered the L-arginine-induced increase in oxidation anddecrease in antioxidative capacity

The antioxidant effects observed in the treatment withHEVm can be caused by the compounds present in thisextract The phenolic compounds found in HEVm likeanthocyanins rutin catechin and epicatechins and otherphenolic compounds (eg quercetin kaempferol ellagicacid and p-coumaric acid) are present in cranberries (forreview see [21 22]) and certainly contributed to the reductionof oxidative stress which in turn decreased the pancreaticlesions and resulted in less severe extrapancreatic alterationsin mice

An important concern about cranberry extracts is regard-ing their safety Many studies have found no toxicity aftertreatment with cranberry extracts for 6ndash10 weeks in exper-imental animals [5 6 38] or in humans [39 40] but arecent study found small differences in the spleen and kidneyfunction of the progeny ofmice treatedwith cranberry extractduring pregnancy [41]Thusmore specific studies are neededto assure the safety of cranberry extracts

Altogether our results indicate a protective role of HEVmin the model of AP induced by L-arginine by reducing pan-creatic damage hyperalgesia and remote alterations throughthe key participation of the antioxidant capacity of thisextract These findings provide insights into the possible useof this extract in the treatment of this disease

Following AP induction many extrapancreatic responseswere observed in animals injected with L-arginine such asthe increased MPO activity in lung and increased markersof hepatic injury Although the mechanisms underlyingthese alterations are not well understood in this modelof pancreatitis the beneficial effect of HEVm is supportedby these results Serum ALT and AST levels were used asmarkers of extrapancreatic alterations in the present studyThe increase in ALT but not AST is usually predictiveof biliary pancreatitis [30] However in the model of L-arginine-induced AP in rats other authors have shown thatboth AST and ALT are increased [31] but no study haspreviously measured these enzymes in mice Interestinglythis increase in hepatic enzymes was partially reduced by theadministration of HEVm which may in part be due to thereduction of pancreatic lesions as observed by the decreaseof pancreatic inflammatory markers and enzymes (amylaseand lipase)

Lung injury is the secondary effect of pancreatitismost related to mortality in patients [32] In the modelof L-arginine-induced pancreatitis lung MPO activity wasincreased 72 h after induction corroborating previous find-ings [9] The fact that the treatment with HEVm reducedlungMPOactivity is complementary to the above-mentionedextrapancreatic protective effects which might be a conse-quence of the reduction of pancreatic damage Pancreatitis-related lung injury is multifactorial and is associated withmany factors such as the presence of activated enzymesdestruction of the lung surfactant low lung perfusion ratesand increased cytokine in lung tissue [33] Interestingly

in agreement with the decrease in lung MPO activity wedetected lower TNF-120572 IL-1120573 and IL-6 levels in lungs ofanimals treated with HEVm in comparison to the vehicle-treated group

Since theHEVm is rich in flavanols and other polyphenolsand these compounds have antioxidant effects [11 34 35] wespeculated that the beneficial actions observed in pancreaticand extrapancreatic parameters could take place with theinvolvement of antioxidant activity In fact increased TBARSand carbonyl groups in parallel with decreased NP-SH andtotal antioxidant capacity (FRAP) in both pancreas and lungindicated that oxidative stress plays a significant role inthis model as previously shown [11 36] Treatment withHEVm maintained antioxidant capacity of the tissue (NP-SH and FRAP) and consequently reduced the oxidationmarkers (MDA and carbonyl) which can be attributedto the direct antioxidant effect of polyphenols found inHEVm [11 22 23 34 37] Another reasonable possibility ofexplaining the antioxidant effect of HEVm is modulation ofthe activity of endogenous antioxidant enzymes Pancreatitisinduction was characterized by reduction of the activity ofCAT SOD and GPx in pancreas and lung corroboratingprevious findings [11] The CAT and SOD activities weremarkedly altered by the treatment with HEVm indicatingthat HEVm strongly modulates oxidative stress InterestinglyCAT and SOD activities seemed to be more susceptible toreversion in pancreas than in lung which agrees with theidea that the reduction of pancreatic damage was importantto the modulation of extrapancreatic effects The beneficialmodulation of CAT and SOD activities in animals treatedwith HEVm was more evident than GPx activity whichwas not altered by treatment with HEVm Indeed HEVmcountered the L-arginine-induced increase in oxidation anddecrease in antioxidative capacity

The antioxidant effects observed in the treatment withHEVm can be caused by the compounds present in thisextract The phenolic compounds found in HEVm likeanthocyanins rutin catechin and epicatechins and otherphenolic compounds (eg quercetin kaempferol ellagicacid and p-coumaric acid) are present in cranberries (forreview see [21 22]) and certainly contributed to the reductionof oxidative stress which in turn decreased the pancreaticlesions and resulted in less severe extrapancreatic alterationsin mice

An important concern about cranberry extracts is regard-ing their safety Many studies have found no toxicity aftertreatment with cranberry extracts for 6ndash10 weeks in exper-imental animals [5 6 38] or in humans [39 40] but arecent study found small differences in the spleen and kidneyfunction of the progeny ofmice treatedwith cranberry extractduring pregnancy [41]Thusmore specific studies are neededto assure the safety of cranberry extracts

Altogether our results indicate a protective role of HEVmin the model of AP induced by L-arginine by reducing pan-creatic damage hyperalgesia and remote alterations throughthe key participation of the antioxidant capacity of thisextract These findings provide insights into the possible useof this extract in the treatment of this disease

4 Discussion

The need for new experimental alternatives to treat AP isstill a challenge since there are no specific treatments forclinical management of this disease [3] In this study wepresent data that demonstrates that HEVm can modulatethe inflammatory response in pancreas and lung (with theparticipation of oxidative stress) and abdominal hyperalgesiaduring L-arginine-induced AP The finding that HEVm hasbeneficial effect in experimental pancreatitis is novel forthis extract which is frequently used by people to treatinflammatory conditions of the urinary system [8] Howeverthe presence of flavonoids in this extract supports the pos-sibility of a beneficial effect on AP For this reason we usedthe hydroethanolic extract of cranberry Our current datareinforce this hypothesis in themodel of pancreatitis inducedby L-arginine

The phytochemical analysis of HEVm showed that cat-echins and epicatechins are its major components It waspossible to identify three flavan-3-ols one flavonol andthree anthocyanins Catechin epicatechins and cyanidinderivatives were previously described in cranberry prepara-tions [21 22] as was quercetin-3-O-rutinoside (rutin) [23]These compounds exert various biological effects includingantioxidant and anti-inflammatory effects [11 21]

Treatment with HEVm induced protective effects againstpancreatic inflammation The activity of MPO edema indexand production of cytokines (TNF-120572 IL-1120573 and IL-6) werereduced by this extract Along with the lower pancreaticdamage in animals treated with HEVm the levels of serumamylase and lipase were lower which corroborates thereduction of pancreatic damage Neutrophil infiltration isa hallmark of AP [24] and our data show that HEVm caninterfere with the presence of these cells in the pancreasThisagrees with previous findings that cranberry extract reducesthe MPO activity in mice paws injected with carrageenan[23] Similarly treatment with 15 dried whole cranberrypowder (incorporated in the diet) reduced MPO activity inthe colon of mice submitted to dextran sulphate sodium-induced colitis [25] Altogether these results highlight theanti-inflammatory effect of the extract of fruits of V macro-carpon In accordance with this effect treatment with HEVmproduced antiedematogenic effect Corroborating this find-ing [23] showed that the extract of V macrocarpon fruitsreduces the production of prostaglandins in vitro possessesantioxidant activity and inhibits carrageenan-induced micepaw edema The reduction of neutrophil migration to thepancreas and edema formation induced by HEVm certainlyare dependent on the inhibitory activity of proinflammatorycytokines Our results demonstrate that pancreatic contentsof TNF-120572 IL-1120573 and IL-6were reduced by the treatmentwithHEVmOther studies have also demonstrated that the extractof cranberry inhibited IL-6 IL-8 and prostaglandin E2 pro-duction by gingival fibroblasts stimulated with lipopolysac-charide in vitro [26] and that serum IL-1120573 and interferon-120574 concentrations and TNF-120572 and IL-1120573 mRNA expressionin colon were reduced by treatment with cranberry inmice submitted to dextran sulphate sodium-induced colitis[25]

in agreement with the decrease in lung MPO activity wedetected lower TNF-120572 IL-1120573 and IL-6 levels in lungs ofanimals treated with HEVm in comparison to the vehicle-treated group

Since theHEVm is rich in flavanols and other polyphenolsand these compounds have antioxidant effects [11 34 35] wespeculated that the beneficial actions observed in pancreaticand extrapancreatic parameters could take place with theinvolvement of antioxidant activity In fact increased TBARSand carbonyl groups in parallel with decreased NP-SH andtotal antioxidant capacity (FRAP) in both pancreas and lungindicated that oxidative stress plays a significant role inthis model as previously shown [11 36] Treatment withHEVm maintained antioxidant capacity of the tissue (NP-SH and FRAP) and consequently reduced the oxidationmarkers (MDA and carbonyl) which can be attributedto the direct antioxidant effect of polyphenols found inHEVm [11 22 23 34 37] Another reasonable possibility ofexplaining the antioxidant effect of HEVm is modulation ofthe activity of endogenous antioxidant enzymes Pancreatitisinduction was characterized by reduction of the activity ofCAT SOD and GPx in pancreas and lung corroboratingprevious findings [11] The CAT and SOD activities weremarkedly altered by the treatment with HEVm indicatingthat HEVm strongly modulates oxidative stress InterestinglyCAT and SOD activities seemed to be more susceptible toreversion in pancreas than in lung which agrees with theidea that the reduction of pancreatic damage was importantto the modulation of extrapancreatic effects The beneficialmodulation of CAT and SOD activities in animals treatedwith HEVm was more evident than GPx activity whichwas not altered by treatment with HEVm Indeed HEVmcountered the L-arginine-induced increase in oxidation anddecrease in antioxidative capacity

The antioxidant effects observed in the treatment withHEVm can be caused by the compounds present in thisextract The phenolic compounds found in HEVm likeanthocyanins rutin catechin and epicatechins and otherphenolic compounds (eg quercetin kaempferol ellagicacid and p-coumaric acid) are present in cranberries (forreview see [21 22]) and certainly contributed to the reductionof oxidative stress which in turn decreased the pancreaticlesions and resulted in less severe extrapancreatic alterationsin mice

An important concern about cranberry extracts is regard-ing their safety Many studies have found no toxicity aftertreatment with cranberry extracts for 6ndash10 weeks in exper-imental animals [5 6 38] or in humans [39 40] but arecent study found small differences in the spleen and kidneyfunction of the progeny ofmice treatedwith cranberry extractduring pregnancy [41]Thusmore specific studies are neededto assure the safety of cranberry extracts

Altogether our results indicate a protective role of HEVmin the model of AP induced by L-arginine by reducing pan-creatic damage hyperalgesia and remote alterations throughthe key participation of the antioxidant capacity of thisextract These findings provide insights into the possible useof this extract in the treatment of this disease
