OBJECTIVE: This study was aimed to evaluate the cardioprotective potential of combination of T. arjuna andα-tocopherol in isoproterenol induced myocardial injury.
METHODS: Wistar albino rats were pre-treated with hydroalcoholic extract of T. arjuna (HETA) andα-tocopherol (100 mg/kg b. w) daily for 30 days. Isoproterenol (ISP, 85 mg/kg b.w) was administered on 28th and 29th days at an interval of 24 hr.
RESULTS: ISP treated rats showed significant increase in lipid peroxidation (MDA), cardiac markers (CK-MB, SGOT, Trop I and LDH), pro-inflammatory cytokine (IL-6, CRP, TNF-α) levels and apoptotic markers (Bcl-2/Bax) as compared to healthy group. Pre-treatment with HETA 100 mg/kg b. w, reduced the elevated levels of these markers and significant effect (p<0.05) were observed with the combination of HETA andα-tocopherol at a dose of 100 mg/kg b. w, which was further confirmed by histopathological studies.
CONCLUSION: The present study concluded that the combination ofα-tocopherol (100 mg/kg b. w) and hydroalcoholic extract of T. arjuna (100 mg/kg b. w) augments endogenous antioxidant compounds of rat heart and also prevents the myocardium from ISP-induced myocardial injury and it may have therapeutic and prophylactic value in the treatment of ischemic heart disease.
