Protective Effects of Panax notoginseng Saponins against High Glucose-Induced Oxidative Injury in Rat Retinal Capillary Endothelial Cells

Figure 4

PNS increased the activities of total SOD, Mn-SOD, CAT, and GSH-PX in rat RCECs exposed to high glucose. Rat RCECs were incubated with concentration of PNS (100 μg/mL) in 30 mM glucose for 72 h; cells were collected and subjected for total SOD, MnSOD, CAT, and GSH-PX determination. The results showed that PNS increased the activities of total SOD, MnSOD, CAT, and GSH-PX in rat RCECs incubated with 30 mM glucose. Data are expressed as the mean ± SD (). versus 5.5 mM glucose; versus 30 mM glucose.
