Figure 7. Effects of ZG on oxidative stress markers in testicular tissue of CP-treated mice. SOD activity, CAT activity, and MDA levels. CP administration significantly reduced SOD and CAT activities (p<0.001 vs. control) while increasing MDA content (p<0.001). ZG pretreatment at 20 and 40 mg/kg (CP +ZG20 and CP +ZG40 groups) significantly restored SOD (^#p<0.05) and CAT activity (^##p<0.01), and dose-dependently reduced MDA levels (^#p<0.05, ^##p<0.01) compared to CP group. ZG alone showed no significant effects on antioxidant indices versus controls. Data represent mean±SD (n=6 groups). *p<0.05, **p<0.01, ***p<0.001 vs. control group; ^#p<0.05, ^##p<0.01 vs. CP group (one-way ANOVA with Tukey’s post-hoc test).
