Background: The major aim of this work was to study the protective effects of fish oil (FO), allopurinol, and verapamil on hepatic ischemia-reperfusion (IR)-induced injury in experimental rats. Materials and Methods: Sixty male Wistar albino rats were randomly assigned to six groups of 10 rats each. Group 1 served as a negative control. Group 2 served as hepatic IR control injury. Groups 3, 4, 5, and 6 received N-acetylcysteine (standard), FO, allopurinol, and verapamil, respectively, for 3 consecutive days prior to ischemia. All animals were fasted for 12 h, anesthetized and underwent midline laparotomy. The portal triads were clamped by mini-artery clamp for 30 min followed by reperfusion for 30 min. Blood samples were withdrawn for estimation of serum alanine transaminase (ALT) and aspartate transaminase (AST) activities as well as hepatic thiobarbituric acid reactive substances, reduced glutathione, myeloperoxidase, and total nitrate/nitrite levels, in addition to histopathological examination. Results: Fish oil, allopurinol, and verapamil reduced hepatic IR injury as evidenced by significant reduction in serum ALT and AST enzyme activities. FO and verapamil markedly reduced oxidative stress as compared to control IR injury. Levels of inflammatory biomarkers in liver were also reduced after treatment with FO, allopurinol, or verapamil. In accordance, a marked improvement of histopathological findings was observed with all of the three treatments. Conclusion: The findings of this study prove the benefits of FO, allopurinol, and verapamil on hepatic IR-induced liver injury and are promising for further clinical trials.

Keywords: Allopurinol, fish oil, ischemia-reperfusion, verapamil.
