SchA Ameliorates Inflammatory Cells and Factors in the BALF of CS-induced COPD Model Mice. A Representative images of leukocytes in BALF from each group (scale bar = 100 μm). B The numbers of total cells, macrophages and neutrophils in BALF. C The levels of IL-6, IL-1β and TNF-α in BALF were measured. n = 6 mice per group. Data are shown as the mean ± SEM (B Neutrophils and Macrophages in BALF, C) and median ± IQR (B Total cell counts in BALF). To test for group differences, Games–Howell (B Neutrophils and Macrophages in BALF, C IL-6 and TNF-α), Tukey (C IL-1β) and Kruskal‒Wallis (B Total cell counts in BALF) 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
