Effects of COE on MDA (a), SOD (b), GSH-Px (c), CAT (d), and T-AOC (e) in the serum (□) and liver (■) in diabetic model mice. MDA: the content of malondialdehyde; T-AOC: total antioxidant capacity; SOD: activity of superoxide dismutase; GSH-Px: activity of glutathione peroxidase; CAT: activity of catalase. Mice were supplemented with COE at 50 (COE-L) or 200 (COE-H) mg/kg body weight and rosiglitazone at 4 mg/kg body weight (ROS) for 4 weeks. In the y-coordinate of graphs (b), (c), (d), and (e), where two units are present, one unit was U/mL or linked with U/mL represented the unit of serum indexes and another unit was U/mgprot or linked with U/mgprot represented the unit of liver indexes. Data were presented as mean ± standard deviation (n = 8). ∗P < 0.05 and ∗∗P < 0.01 compared to group DM; ΔP < 0.05 and ΔΔP < 0.01 compared to group NC.
