Figure 4.
Effects of Dox and myricitrin on apoptosis in vivo and in vitro. Internucleosomal DNA fragmentation of H9c2 cardiomyocytes and heart tissues was determined using the TUNEL assay ((a) and (b)). The TUNEL apoptotic index was determined by calculating the ratio of TUNEL-positive cells to total cells ((c) and (d)). All data are expressed as the means ± SD (n = 3 per group). # P < 0.05 versus Cont; ∗ P < 0.05 versus Dox.
