EA intervention ameliorates excessive oxidative stress in local hindpaw tissues of CPIP rats. Results showing SOD activity (a), GSH-Px activity (b), MDA content (c), and H₂O₂ content (d) determined in ipsilateral hindpaw tissues of the control, CPIP, CPIP+EA, and CPIP+sham EA groups 7 d after model establishment. (e) Representative pictures showing 8-OHG immunostaining in ipsilateral hindpaw tissues of each group. (f) Summarized data of normalized fluorescence intensity of 8-OHG per observation field of each group. (g) 4-HNE expression determined by Western blot in ipsilateral hindpaw tissues of each group. n = 6 rats/group. ^∗p < 0.05 and ^∗∗p < 0.01 vs. the control group. ^#p < 0.05 and ^##p < 0.01 vs. the CPIP+sham EA group.
