STS attenuates CS-induced emphysema, inflammation, remodeling of the airway and goblet cell hypertrophy and hyperplasia of the airway epithelium. Comparison of H&E or Masson or PAS staining of lung sections from CTL, CS, CS plus STS (CS + STS) and STS-treated mice was performed. Software IPP6.0 was used to assess the average linear intercept (Lm) of alveoli (A), small airway remodeling (B) and goblet cell hyperplasia (C) in at least three fields of lung section per mouse. *P < 0.05 and **P < 0.01 (n = 5 mice per group). STS, Sodium tanshinone IIA sulfonate; CS, cigarette smoke.
