(a) Hematoxylin and eosin staining was used to observe lung injury in mice. (b) Masson’s trichrome staining was used to observe pulmonary fibrosis in mice. (c) Sirius red staining was used to observe collagen deposition in the lungs of mice. (d) Collagen distribution volume statistics using Masson’s trichrome staining images; and (e) collagen distribution volume statistics for Sirius red staining images (calculated by Image Pro Plus) (, , vs. the PF group; #### vs. the Sham group). (f, g) The wet-to-dry ratio and hydroxyproline content for each group ( vs. the PF group; #, ## vs. the Sham group).
