Introduction: We aimed to investigate the possible protective effects of ellagic acid (EA) on the liver and remote organs against the hepatic ischemia-reperfusion injury. Methods: Forty Wistar-Albino rats were divided into four groups each containing 10 rats. Group I with laparotomy only, Group II with laparatomy and ellagic acid application, Group III with hepatic ischemia-reperfusion and Group IV with hepatic ischemia-reperfusion and ellagic acid application. Hepatic ischemia was induced by pringle's manoeuvre for 30 minutes followed by 30 minutes reperfusion period. After induction of ischemia, EA was applied via oral gavage at a dose of 85 mg/kg. Blood samples were taken from the animals for biochemical analysis at 60th minute of the experiment in all groups. Simultaneously, liver, lung and kidney tissues were sampled for biochemical analyses and histopathological examinations. Results: The administration of EA reduced serum malonyldialdehid levels (p<0.05) and liver's oxidative stress index compared with the non-use EA groups (p<0.05). Although, ameliorated liver histopathological changes were seen in EA groups, these changes were not statistically significant (p>0.05). The use of EA did not exert significant protective effects against the effects of liver ischemia-reperfusion injury on the kidney and lung. Conclusion: In our experiments ellagic acid reduced the liver oxidative stress induced by ischemia-reperfusion injury. However, no significant histological improvement was found with EA. There were no significant protective effects on the remote organ injuries induced by ischemia-reperfusion (Tab. 3, Fig. 7, Ref. 37). Full Text in PDF www.elis.sk.
