| 1 | Stable gastric pentadecapeptide BPC 157 in the treatment of colitis and ischemia and reperfusion in rats: New insights显示文摘AIM To provide new insights in treatment of colitis and ischemia and reperfusion in rats using stable gastric pentadecapeptide BPC 157. METHODS Medication [BPC 157,L-NAME,L-arginine(alone/combined),saline] was bath at the blood deprived colon segment. During reperfusion,medication was BPC 157 or saline. We recorded(USB microscope camera) vessel presentation through next 15 min of ischemic colitis(ICrats) or reperfusion(removed ligations)(IC + RL-rats);oxidative stress as MDA(increased(IC-and IC + RLrats)) and NO levels(decreased(IC-rats);increased(IC + RL-rats)) in colon tissue. IC + OB-rats [IC-rats had additional colon obstruction(OB)] for 3 d(IC + OBrats),then received BPC 157 bath. RESULTS Commonly,in colon segment(25 mm,2 ligations on left colic artery and vein,3 arcade vessels within ligated segment),in IC-,IC + RL-,IC + OB-rats,BPC 157(10 μg/kg) bath(1 m L/rat) increased vessel presentation,inside/outside arcade interconnections quickly reappeared,mucosal folds were preserved and the pale areas were small and markedly reduced. BPC 157 counteracted worsening effects induced by L-NAME(5 mg) and L-arginine(100 mg). MDA-and NO-levels were normal in BPC 157 treated IC-rats and IC + RLrats. In addition,on day 10,BPC 157-treated IC + OBrats presented almost completely spared mucosa with very small pale areas and no gross mucosal defects;the treated colon segment was of normal diameter,and only small adhesions were present.CONCLUSION BPC 157 is a fundamental treatment that quickly restores blood supply to the ischemically injured area and rapidly activates collaterals. This effect involves the NO system. | Antonija Duzel Josipa Vlainic Marko Antunovic Dominik Malekinusic Borna Vrdoljak Mariam Samara Slaven Gojkovic Ivan Krezic Tinka Vidovic Zdenko Bilic Mario Knezevic Marko Sever Nermin Lojo Antonio Kokot Marijan Kolovrat Domagoj Drmic Jaksa Vukojevic Tamara Kralj Katarina Kasnik Marko Siroglavic Sven Seiwerth Predrag Sikiric | 2017 | World Journal of Gastroenterology2017,23,48: | 2 |

| 4 | Counteraction of perforated cecum lesions in rats: Effects of pentadecapeptide BPC 157,L-NAME and L-arginine显示文摘AIM To study the counteraction of perforated cecum lesion using BPC 157 and nitric oxide(NO) system agents.METHODS Alongside with the agents' application(after 1 min, medication(/kg, 10 ml/2 min bath/rat) includes: BPC 157(10 μg), L-NAME(5 mg), L-arginine(100mg) alone or combined, and saline baths(controls)) on the rat perforate cecum injury, we continuously assessed the gross reappearance of the vessels(USB microcamera) quickly propagating toward the defect at the cecum surface, defect contraction, bleeding attenuation, MDA-and NO-levels in cecum tissue at 15 min, and severity of cecum lesions and adhesions at 1 and 7 d. RESULTS Post-injury, during/after a saline bath, the number of vessels was significantly reduced, the defect was slightly narrowed, bleeding was significant and MDA-levels increased and NO-levels decreased. BPC 157 bath: the vessel presentation was markedly increased, the defect was noticeably narrowed, the bleeding time was shortened and MDA-and NO-levels remained normal. L-NAME: reduced vessel presentation but not more than the control, did not change defect and shortened bleeding. L-arginine: exhibited less vessel reduction, did not change the defect and prolonged bleeding. In combination, mutual counteraction occurred(L-NAME + L-arginine) or the presentation was similar to that of BPC 157 rats(BPC 157 + L-NAME; BPC 157 + L-arginine; BPC 157 + L-NAME + L-arginine), except the defect did not change. Thereby at day 1 and 7, saline, L-NAME, L-arginine and L-NAME + L-arginine failed(defect was still open and large adhesions present). CONCLUSION The therapeutic effect was achieved with BPC 157 alone or in combination with L-NAME and L-arginine as it was able to consolidate the stimulating and inhibiting effects of the NO-system towards more effective healing recruiting vessels. | Domagoj Drmic Mariam Samara Tinka Vidovic Dominik Malekinusic Marko Antunovic Borna Vrdoljak Jelena Ruzman Marija Milkovic Perisa Katarina Horvat Pavlov Jerusha Jeyakumar Sven Seiwerth Predrag Sikiric | 2018 | World Journal of Gastroenterology2018,24,48: | 1 |

| 6 | Bypassing major venous occlusion and duodenal lesions in rats, and therapy with the stable gastric pentadecapeptide BPC 157, L-NAME and L-arginine显示文摘AIM To investigate whether duodenal lesions induced by major venous occlusions can be attenuated by BPC 157 regardless nitric oxide(NO) system involvement.METHODS Male Wistar rats underwent superior anterior pancreaticoduodenal vein(SAPDV)-ligation and were treated with a bath at the ligated SAPDV site(BPC 157 10 μg, 10 ng/kg per 1 mL bath/rat; L-NAME 5 mg/kg per 1 m L bath/rat; L-arginine 100 mg/kg per 1 mL bath/rat, alone and/or together; or BPC 157 10 μg/kg instilled into the rat stomach, at 1 min ligation-time). We recorded the vessel presentation(filled/appearance or emptied/disappearance) between the 5 arcade vessels arising from the SAPDV on the ventral duodenum side, the inferior anterior pancreaticoduodenal vein(IAPDV) and superior mesenteric vein(SMV) as bypassing vascular pathway to document the duodenal lesions presentation; increased NO-and oxidative stress [malondialdehyde(MDA)]-levels in duodenum.RESULTS Unlike the severe course in the SAPDV-ligated controls, after BPC 157 application, the rats exhibited strong attenuation of the mucosal lesions and serosal congestion, improved vessel presentation, increased interconnections, increased branching by more than 60% from the initial value, the IAPDV and SMV were not congested. Interestingly, after 5 min and 30 min of L-NAME and L-arginine treatment alone, decreased mucosal and serosal duodenal lesions were observed; their effect was worsened at 24 h, and no effect on the collateral vessels and branching was seen. Together, L-NAME+L-arginine antagonized each other's response, and thus, there was an NO-related effect. With BPC 157, all SAPDV-ligated rats receiving L-NAME and/or L-arginine appeared similar to the rats treated with BPC 157 alone. Also, BPC 157 in SAPDV-ligated rats normalized levels of NO and MDA, two oxidative stress markers, in duodenal tissues.CONCLUSION BPC 157, rapidly bypassing occlusion, rescued the original duodenal flow through IAPDV to SMV flow, aneffect related to the NO system and reduction of free radical formation. | Fedor Amic Domagoj Drmic Zdenko Bilic Ivan Krezic Helena Zizek Marina Peklic Robert Klicek Alen Pajtak Enio Amic Tinka Vidovic Mislav Rakic Marija Milkovic Perisa Katarina Horvat Pavlov Antonio Kokot Ante Tvrdeic Alenka Boban Blagaic Mario Zovak Sven Seiwerth Predrag Sikiric | 2018 | World Journal of Gastroenterology2018,24,47: | 1 |
