Fig. 4From: Buyang Huanwu Decoction attenuates H2O2-induced apoptosis by inhibiting reactive oxygen species-mediated mitochondrial dysfunction pathway in human umbilical vein endothelial cellsEffects of BYHWD on H2O2-induced apoptosis in HUVECs. a Apoptotic cells were observed using a fluorescence microscope by Hoechst 33342 and PI staining in HUVECs. b Quantitative data showed the percentage of apoptotic cells according to treatment in HUVECs. Values are shown as means ± SD (n = 10). **P < 0.01, compared to sham group. ##P < 0.01, compared to H2O2 group (320 μmol/l)Back to article page
