SOD: superoxide dismutase; GSH-Px: glutathione peroxidase. *P < 0.05, , , and (#: compared with normal control group; *: compared with model control group).
aOne unit of SOD activity is defined as amount of SOD when SOD inhibition ratio reaches 50% in 1 mL reaction solution.
bOne unit of GSH-Px activity is defined as amount of enzyme required to degrade 1 μmol/L of GSH per min subtracting nonenzymatic reaction at 37°C.
