Effect of paeoniflorin on the proliferative ability of HUVECs. (A) The cells were incubated with the different concentrations of paeoniflorin for 24 h. (B) HUVECs were incubated with 0.5 μmol/l paeoniflorin and the viability was measured at 0, 24, 48, 72 and 96 h. The proliferative ability of HUVECs was improved compared with control HUVECs. Values are expressed as the mean ± standard deviation. *P<0.05 vs. (A) the control group and (B) the HUVECs. OD, optical density; HUVEC, human umbilical vein endothelial cell; MTT, 3-(4,5dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide.
