Abstract
OBJECTIVES: This study is designed to evaluate the cardioprotective effect of fenugreek on isoproterenol- induced myocardial infarction and is investigated by an in vivo method in rats. MATERIALS AND METHODS: Male Wistar albino rats were divided into four groups (n=10). Group I received 0.5% CMC treated as normal control group. Group II received isoproterenol (85 mg/kg body weight) intraperitoneal (i.p.) for two consecutive days (14(th) and 15(th) days). Group III received fenugreek (250 mg/kg body weight) intragastric intubation for 15 days. Group IV rats received fenugreek as in Group III and additionally isoproterenol was given for two consecutive days (14(th) and 15(th) days). RESULTS: The results described the cardioprotective effect that observed in Group IV showed significantly (P< 0.05) decreased levels of TBARS and enhanced the activities of both enzymatic and non-enzymatic antioxidants (SOD, CAT, GPx and GSH) in myocardial infarcted rats when compared to Groups II and III. Histopathological studies were also co-relating with the above biochemical parameters. CONCLUSION: These findings concluded the cardioprotective effect of fenugreek on lipid peroxidation and antioxidant defense system during isoproterenol-induced myocardial infarction in rats.
