Figure 1. The effects of As2O3 and baicalin on viability of human umbilical vein endothelial cells (HUVECs). A: The effects of 24-h treatment of HUVECs with 0-20 μM As2O3. HUVECs were photographed under a microscope at ×40, representative images are shown. B: The quantification of the effect of 0-20 μM As2O3 treatment for 24 h in HUVECs. C: The effect on HUVEC viability after pretreatment with baicalin for 1 h, and cotreatment of baicalin with 20 μM (◆), 10 μM (▲) or 0 μM (●) As2O3 for 24 h. Data are the mean±SD for three independent experiments. *Significantly different at p<0.05 compared with untreated control cells.
