Pathological changes detected using H&E staining in lung tissue after 7 d of OVA excitation and 7 or 28 d of treatment. a, H&E stained lung tissues in CON/MDL/DEX/PCF groups after 7 d of excitation with 5 % OVA nebulization (distilled water for CON group) and the daily subsequent treatment by gavage with distilled water for CON and MDL group, 20 ml/Kg of DEX (0.075 mg/ml) for DEX group and 20 ml/Kg of PCF (5.33 g/ml) for PCF group, respectively (n = 10 for each group); b, H&E stained lung tissues in CON/MDL/DEX/PCF groups after 7 d of excitation with 5 % OVA nebulization (distilled water for mice CON group) and 28 d treatment by gavage the same as in panel A (n = 10 for each group)
