Background: Ischemia and reperfusion (I/R) is a pathological condition characterized by an initial restriction of blood supply to an organ followed by the subsequent restoration of perfusion and concomitant reoxygenation. Objective: The aim of the study is to assess the possible cardio protective potential effect of berberine in myocardial ischemia reperfusion injury induced by ligation of coronary artery in a male rat model. Methods: Total amount of 28 adult male albino rats were randomized into 4 equal groups: 1) Sham group, rats underwent the same anesthetic and surgical procedure as the control group except for LAD ligation; 2), Active control group, rats subjected to regional ischemia for 30 min by ligation of LAD coronary artery and reperfusion for 2 hours, 3), Control vehicle group, rats received dimethyl sulphoxide (DMSO) (vehicle of berberine) via IP route and subjected to ischemia for 30 minutes before ligation of LAD coronary artery & reperfusion for 2 hr; 4), Berberine treated group, rats pretreated with berberine10 mg/kg via IP injection 30minutes before ligation of LAD coronary artery & then subjected to reperfusion for 2 hr. Results: In control group, as compared with sham, tissue TNF-α, IL-6, IL-10, caspase-3 and BAX, plasma cTn-T and serum MDA significantly increased (P
