SchA Treatment Reduces Oxidative Stress in CS-induced COPD Model Mice. The activity of A CAT and B SOD and the levels of C MDA in the right lung tissue. D The relative DHE fluorescence intensity in lung tissues in the different groups. E Representative images of lung sections stained with DHE (rad) and DAPI (blue) (scale bar = 50 μm). n = 6 mice per group. Data are shown as the mean ± SEM (B–D) and median ± IQR (A). To test for group differences, Games–Howell (B–D) and Kruskal‒Wallis (A) tests were used. *p < 0.05, **p < 0.01, ***p < 0.001 versus control group, ^#p < 0.05, ^##p < 0.01, ^###p < 0.001 versus CS group, ⁺p < 0.05, ⁺⁺p < 0.01, ⁺⁺p < 0.001 versus CS + DEX group, ^§p < 0.05, ^§§p < 0.01, ^§§§p < 0.001 versus CS + SchA group
