Effects of dihydroartemisinin on bleomycin-induced pulmonary fibrosis. Lung morphology of saline-treated control rats (A), bleomycin-treated rats (B), and bleomycin-treated rats after treatment with high dose dihydroartemisinin (C) or DXM (D) was evaluated by hematoxylin-eosin staining. Collagen fibers deposition in pulmonary interstitium was evaluated by Masson’s staining in lungs in bleomycin-treated rats (E), and bleomycin-treated rats after treatment with high dose dihydroartemisinin (F).
