SOD1 and type 2 diabetes mellitus: Ginsenoside Re significantly increased the activities of SOD (p < 0.05) and decreased the level of MDA (p < 0.05) in T2DM rats, and the activities of CAT also tended to increase, but the difference was not statistically significant, indicating that ginsenoside Re could mitigate the oxidative stress in T2DM rats.
