DMXBA treatment alleviates chronic restraint stress (CRS)-induced neuronal damage in the CA1 region of hippocampus. a Neuronal damage indicated by Nissl staining in the hippocampus of control (Con) and CRS mice treated with vehicle (Veh), DMXBA, or DMXBA plus α-bungarotoxin (α-BGT); scale bar, 30 μm. b Dendrite segments are revealed by Golgi staining in the CA1 region of hippocampus in the different groups; scale bar, 10 μm. Dendritic spines were counted on a 50-μm segment length in 10 neurons from each section. Con, control group. Data are presented as mean ± SEM. n = 6 per group; *P < 0.05 vs. control group; ^# P < 0.05 vs. CRS 21d + Veh group; ⁺ P < 0.05 vs. CRS 21d + DMXBA group
