Figure 2:Effect of ES intake on plasma GSH-Px, SOD and MDA levels in D-Gal-induced mice. Glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and malondialdehyde (MDA) levels in the serum were determined using ELISA kits as described in the manufacturer’s manual. The Con group was considered as reference 1, the other three groups were compared with the Con group; for MDA, the D-GH group was considered as reference 1, and the other three groups were compared with the D-GH group. Data are exhibited as mean ± standard error (SE) (n=15 mice). *P<0.05 versus the Con group; #P<0.05 versus the D-Gal group.
