| Abstract | Despite considerable advances in diagnosis and management over the last three decades, acute myocardial infarction continues to be a major public health problem. It is predicted that ischemic heart diseases will constitute the major disease-burden worldwide in the year 2020. In the present study, an attempt has been made to examine the effects of dietary chitosan supplementation on lipid peroxidation and cardiac antioxidant defense system in isoprenaline-induced myocardial infarction in rats, an animal model of myocardial infarction in man. Dietary chitosan intake significantly attenuated the isoprenaline-induced lipid peroxidation and maintained the level of reduced glutathione at near normal. Its administration demonstrated an antioxidant effect by maintaining the activities of myocardial glutathione dependent antioxidant enzymes (glutathione peroxidase and glutathione-S-transferase) and antiperoxidative enzymes (superoxide dismutase and catalase) at levels comparable to that of controls. The results of the present study indicate that the salubrious effects of dietary supplementation of chitosan is probably related to a counteraction of free radicals and/or to normal maintenance of the activities of free radical enzymes and the level of GSH, which protect myocardial membrane against oxidative damage by decreasing lipid peroxidation |
