Effects of CUMS five antioxidant indices in hippocampus of mice. a GSH-Px. b MDA. c SOD. d T-AOC. e CAT concentrations in the hippocampus were measured using an oxidative stress-related enzyme test. Each value represents the mean ± SEM. *p < 0.05, **p < 0.01 and ***p < 0.001 means difference of WT Control vs. WT CUMS, TPH2 KO vs. TPH2 KO CUMS, TPH2 KO vs. WT CUMS + FLX at the same point
