Figure 1: Inhibitory effect of H2O2 on HUVECs proliferation. HUVECs, human umbilical vein endothelial cells; LZDMS, long-zhi decoction medicated serum. (a) Proliferation inhibition of HUVECs with different concentrations of H2O2 for 4 h. (b) Proliferation inhibition of HUVECs with 400 μmolL−1 of H2O2 at a series of time points. (c) The effect of each experimental group on HUVECs proliferation. Values are expressed as the mean ± standard error of the mean (). and , compared with the control group; , compared with the control group and blank serum group; , compared with the H2O2 group. LZDMS, long-zhi decoction medicated serum.
