Abstract

Background: Myocardial infarction affects a large population in the world. Lipid peroxide metabolism plays an important role in the pathology of myocardial infarction. Objective: The present study was designed to investigate the antioxidant potential of morin, a flavonoid in isoproterenol (ISO)-induced myocardial infarction (MI), in rats. Materials and Methods: Male albino Wistar rats were pre-treated with morin (40 mg/kg), daily for a period of 30 days. After the treatment period, ISO (85 mg/kg), was subcutaneously injected in rats at an interval of 24 h for 2 days. Results: ISO-administered rats showed elevated levels of thiobarbituric acid reactive substances (TBARS), and lipid hydro-peroxide (LOOH), in plasma and heart. Pretreatment with morin, the above changes were significantly reduced to near normal level. ISO-administered rats showed decrease in the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione-S-transferase (GST) in heart. In addition, decrease the levels non enzymatic antioxidants such as reduced glutathione (GSH), vitamin C and vitamin E in plasma and heart while ceruloplasmin in plasma. Conclusion: Pretreatment with morin, reversed these above biochemical changes towards normalcy. These findings revealed that, the morin possess antioxidant activity in experimentally induced cardiac toxicity.
