Progression of lung fibrosis induced in rabbits by intratracheal bleomycin (BLM, 10 mg/kg) was monitored by biochemical and morphological measurements. These indicated that the evolution of fibrosis in the rabbit was slower than in other experimental animals. Histology revealed cellular and fibrocellular lesions 4 weeks after BLM. At 8 weeks these lesions still predominated, indicating continuing active disease accompanied by a progression to fibrosis. The gradual progression of the response was reflected in alterations in lung composition. Changes in lung content of collagen, protein and DNA were evident at 8 weeks after BLM, at which time concentration (micrograms/mg dry weight) of collagen and protein were also elevated (P less than 0.05). Plasma angiotensin converting enzyme (ACE), a marker of endothelial injury, decreased 1 week after BLM (P less than 0.01) and then returned to normal, indicating that endothelial injury does not parallel the fibrotic response. In summary, the continuing active inflammation and slow progress of fibrosis induced by i.t. BLM in the rabbit suggests that this model has advantages over others for the serial study of the cellular and biochemical evolution of lung fibrosis.
