Alteration of indicators of airway remodeling. (A) Smooth muscle thickness of lung tissues. (B) Collagen deposition in the lungs. Blank control group, non-sensitized and nontreated; model group, sensitized and vehicle-treated; DEX group, sensitized and DEX-treated; SIN groups, sensitized and SIN-treated (25, 50 and 75 mg/kg). All results are presented as the mean ± standard deviation. ^##P<0.01 vs. the control group; ^**P<0.01 or ^*P<0.05 vs. the model group; ^ΔΔP<0.01 or ^ΔP<0.05 vs. the DEX group. DEX, dexamethasone; SIN, sinomenine.
