Figure Lengend Snippet: Injury of mucus hypersecretion and oxidative damage in all groups. (A) AB-PAS staining images of the airway in all groups (AB-PAS; ×200 magnification and ×400 magnification). Arrows indicate goblet cells. (B) The expression level of MUC5AC and MUC5B in the airway tested using immunohistochemistry (×200 magnification). (C) The expression of IL-6, IL-10, TNF-α, T-SOD, MDA, MMP-9 and TIMP-1 in lung tissue and serum of rats in all groups. The values are expressed as mean ± SE; (n=8). *P<0.05 and **P<0.01 vs. normal group. AB-PAS, Alcian blue-periodic acid-schiff; MUC5AC, mucoprotein-5AC; MUC5B, mucoprotein-5B; T-SOD, total superoxide dismutase; MDA, malondialdehyde; MMP-9, matrix metalloproteinase 9; TIMP-1, tissue inhibitor of metalloproteinases 2; IOD, integrated optical density.
