Regulation of Dendrobium Polysaccharides on Proliferation and Oxidative Stress of Human Umbilical Vein Endothelial Cells in the High Glucose Environment

Figure 3

(a) Effect of PDC on SOD activity in HUVECs cells cultured in high glucose. (b) Effect of PDC on NO secretion from HUVECs cells cultured in high glucose. Both D-glucose (33.3 mmol/L) and PDC (100, 200, and 400 μg/mL) were incubated with HUVECs for 48 hours. Detection of SOD activity and NO secretion. C: control group; HG: high D-glucose group; PDC: Dendrobium candidum polysaccharide group. All data are expressed as (). , compared with the control group; #, compared with the high glucose group; ▲, compared with the high glucose + PDC (100 μg/mL) group; ◆, compared with the high glucose + PDC (200 μg/mL) group.
