Abstract
A ltered mitochondrial function and free radical-mediated tissue damage have been suggested as important pathological events in isoproterenol (ISO)-induced cardiotoxicity. This study was undertaken to know the preventive effect of morin on mitochondrial damage in ISO-induced cardiotoxicity in male Wistar rats. Myocardial infarction in rats was induced by isoproterenol (85 mg/kg) at an interval of 24 h for 2 days. Morin was given to rats as pretreatment for 30 days orally using an intragastric tube. Isoproterenol caused a significant increase in the activity of cardiac injury marker enzymes like CK and LDH. Morin pretreatment significantly reduced the concentration of CK and LDH. ISO-treated rats had showed a significant elevation of mitochondrial TBARS and HP level and pre-treatment with morin significantly prevented the increase of TBARS and HP level to near normality. The level of enzymic and non-enzymic antioxidants was decreased significantly in ISO-treated rats and pre-treatment with morin significantly increased the levels of SOD, CAT, GPX, GST and GSH to normality. The activities of mitochondrial enzymes such as isocitrate dehydrogenase (ICDH), α -ketoglutarate dehydrogenase ( α -KGDH), succinate dehydrogenase (SDH) and malate dehydrogenase (MDH) were decreased significantly in ISO treated myocardial ischemic rats and upon pre-treatment with morin restored these enzymes activity to normality. In addition, the decreased activities of cytochrome c oxidase and NADH-dehydrogenases were observed in ISO-treated rats and pre-treatment with morin prevented the activities of cytochrome c oxidase and NADH-dehydrogenase to normality. Pre-treatment with Morin favorably restored the biochemical and functional parameters to near normal indicating morin to be a significant protective effect on cardiac mitochondrial function against ISO induced myocardial infarction in rats
