Effects of atorvastatin on histopathogical changes of bleomycin-induced lung with Masson’s trichrome stain (×400). (A,D) Lung tissue sections of control and atorvastatin alone administrated animals with normal lung morphologies: scarcely deposited collagen in the lung parenchyma; (B) Lung tissue sections of bleomycin-induced animals showing dense collagen accumulations: collagen accumulations in lung parenchyma; and (C) Lung sections of atorvastatin treated animals showing reduced collagen depositions: reduced alveolar thickening with meager collagen.
