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

Figure 5

PNS increased GSH and reduced GSSG contents in rat RCECs exposed to high glucose. Rat RCECs were incubated with PNS (100 μg/mL) in 30 mM of glucose for 72 h; then cells were collected and GSH and GSSG were quantified. The results showed that PNS increased GSH content and reduced GSSG content after incubation with 30 mM of glucose. Data are expressed as the mean ± SD (). versus 5.5 mM glucose; versus 30 mM glucose.
