Ginsenoside Rb1 Reduces Isoproterenol-Induced Cardiomyocytes Apoptosis In Vitro and In Vivo

Figure 5

The apoptotic index of cardiomyocytes in rat. By TUNEL assay, 10 fields with myocytes cut in cross section from each LV tissue were examined to count TUNEL-positive cardiomyocytes. The apoptotic index was measured by TUNEL-positive cardiomyocytes to the total of cardiomyocytes, and results are expressed as means ± SD, ^b𝑃<0.01 versus control; ^d𝑃<0.01 versus ISO.
