1 Means ± S.D. (N = 12) with superscript * indicates that there are significant differences (p < 0.05) compared with the control group in the same row. 2 T-AOC: total antioxidant capacity; T-SOD: total superoxide dismutase; GSH-PX: glutathione peroxidase; MDA: malonaldehyde; ROS: reactive oxygen species; CORT: corticosterone.
