Effects of lithium on enzyme activity from CuZn superoxide dismutase (SOD1) (a), Mn superoxide dismutase (SOD2) (b), catalase (CAT) (c), glutathione peroxidase (GPx) (d), and glutathione reductase (GR) (e) in the hippocampus of animals exposed to CRS. The values are means ± S.E.M. of 10 rats. Statistical significance: ^∗p < 0.05, ^∗∗p < 0.01, and ^∗∗∗p < 0.001 animals exposed to CRS+Li vs. CRS animals (t-test). The final result for enzyme activity was expressed as units per milligram of protein (U/mg).
