The aim of this study was to investigate the effects of hydroxycamptothecin (HCPT) on the expression of matrix metalloproteinase-1 (MMP-1), tissue inhibitor of MMP-1 (TIMP-1), and type I collagen in the lung tissue of rats with pulmonary fibrosis induced by bleomycin A5. We used hematoxylin eosin staining to observe the degree of pulmonary fibrosis in rats; Masson staining, reverse transcription polymerase chain reaction, and immunohistochemistry were used to observe the expression of collagen, MMP-1, and TIMP-1, and type I collagen.
