Myocardial infarction is a major public health concern and the leading cause of death throughout the world. The present study investigates the ability of Aegle marmelos fruit extract to prevent pathological changes and oxidative stress after isoproterenol induced myocardial infarction in rats. In vitro studies showed that Aegle marmelos fruit extract possesses antioxidant activity. Administration of isoproterenol (85 mg/kg body weight) to rats resulted in significantly elevated plasma transaminases, lactate dehydrogenase and creatine kinase, however, cardiac tissue analyses showed decreased activity of the above enzymes compared to experimental control rats. Further, isoproterenol administration significantlyincreased plasma and cardiac tissue thiobarbituric acid reactive substances and lowered the activities of cardiac tissue superoxide dismutase, catalase, reduced glutathione, glutathione peroxidase and glutathione-S-transferase when compared to control groups. Pretreatment with Aegle marmelos fruit extract at a dose of 150 mg/kg body weight for a period of 45 days significantly prevented the observed alterations. Our data suggest that Aegle marmelos fruit extract exerts its protective effect by decreasing thiobarbituric acid reactive substances and elevating antioxidants status in isoproterenol treated rats. Both biochemical and histopathological results in the isoproterenol-induced myocardial infarction model emphasize the beneficial action of Aegle marmelos fruit extract as a cardioprotective agent.
