PB protected against oxidative stress in hippocampus of CUMS mice a PB inhibited ROS production, which was measured using the DCFH-DA fluorescent probe under a fluorescence microscope at a magnification of × 400. b The fluorescence intensity was calculated and was correlated with the ROS level. c The concentration of MDA was measured, suggesting that PB decreased MDA concentration in CUMS mice. d The activity of SOD was measured, indicating that PB promoted SOD activity in CUMS mice. **p < 0.01 vs. Control. ##p < 0.01 vs. CUMS
