Background: The present study establishes the cardioprotective role of Thraatchathi Chooranam (TC), a polyherbal traditional Siddha medicine, in terms of membrane stabilizing and antioxidant properties in isoproterenol (ISO) induced myocardial necrosis model in rats. Methods: Animals were divided into six groups (n = 6), normal (received vehicle 0.5% CMC, p.o.), ISO control (received 0.5% CMC + ISO 120 mg/kg, b.w. s.c. twice at an interval of 48 h), standard control (received Vit-E 100 mg/kg, p.o.) + ISO, TC low and high dose (50 and 100 mg/kg p.o., respectively) + ISO, and drug control (received TC at 100 mg/kg, p.o.). At the end of experimental period, blood samples collected and plasma cardiac troponin-I (CTn-I) was measured by ELISA. Cardiac tissues were isolated, levels of membrane stabilizing enzymes, antioxidants and inflammatory markers were estimated. Gene expression of Bax, Bcl2, Caspase 3, HIF-α, TNF-α, iNOS, TRX1 and TrxR were performed by RT-PCR. Histopathological studies on cardiac tissues were conducted using hematoxylin and eosin (H&E) stain. Statistical analyses were performed by one-way ANOVA followed by Tukey’s multiple comparison as post-hoc test. Results: Administration of ISO resulted in a significant increase in plasma CTn-I, decrease in superoxide dismutase, glutathione and glutathione peroxidase; it also significantly altered membrane stabilizing enzymes like Na+/K+-ATPase, Mg2+-ATPase Ca2+-ATPase and Cathepsin D. Pretreatment with TC (50 mg/kg and 100 mg/kg) decreased CTn-I, and improved membrane stabilizing and endogenous antioxidant enzymes and decreased cathespin D level in a dose dependent manner. Histopathological examination revealed that TC improves cellular membrane integrity and decreases inflammatory cell infiltration and necrotic death. Conclusion: The present study provided a strong evidence on the protective effects of TC against ISO-induced myocardial necrosis in rats.
