[Objective] To observe the protective effect of swertiamarin on H2O2-induced apoptosis of rat's cardiomyocyte and to explore its protective mechanism.[Methods] Cultured with differential attachment methods,the cell viability and content of Superoxide dismutase(SOD) and Malondia ldehyde MDA of SD rat's cardiomyocyte of were determined;the expression of bcl-2 and Bax of cardiomyocyte was detected with immunocytochemical staining and the cell apoptosis was detected using acridine orange staining.[Results] The ...
