Acupuncture inhibited hippocampal oxidative stress and neuronal loss in 2VO‐operated rats. Representative images and quantitative graph of Nissl staining (A,B) and DHE staining (C,D) in hippocampal CA1 region in sham, 2VO, 2VO + Acu, and 2VO + Non‐acu groups. Immunohistochemical staining was used to show the 8‐OHdG expression in CA1 region in sham, 2VO, 2VO + Acu, and 2VO + Non‐acu groups (200 × , scale bar= 100 μm) (E,F). Quantitative analysis of hippocampal SOD activity in these four groups (G). Values are means ± SEM (n = 10 for each group). *P < 0.05, 2VO vs Sham. ^# P < 0.05, 2VO+Acu vs 2VO. ^& P < 0.05, 2VO+Acu vs 2VO+Non‐acu
