Antilipoperoxidative and antioxidant effects of S-allyl cysteine sulfoxide on isoproterenol-induced myocardial infarction in Wistar rats.
Our study evaluates the preventive effect of S-allyl cysteine sulfoxide (SACS) on lipid peroxidative products and enzymic and nonenzymic antioxidants in isoproterenol (ISO) induced myocardial infarction in rats. The male Wistar rats were rendered myocardial infarction by ISO (150 mg kg(-1), once a day for two days). The concentrations of thiobarbituric acid reactive substances and lipid hydroperoxides were increased in hearts from ISO-treated rats, whereas the content of enzymic and nonenzymic antioxidants were declined in rats administered ISO. Oral pretreatment with SACS (40 mg kg(-1) and 80 mg kg(-1) daily for a period of 35 days) significantly (p < 0.05) decreased the lipid peroxidative products and significantly (p < 0.05) increased antioxidants in ISO-induced rats. Oral administration of SACS (40 mg kg(-1) and 80 mg kg(-1)) did not show any significant effect in normal rats. Thus, the present study shows that SACS exhibits antilipoperoxidative and antioxidant effects in experimental myocardial infarction.
