Two hundred male mice, weighing 18-24g, were randomized into four groups. A model of lung injury was established in mice by intratracheal administration of a single dose of domestic pingyangmycinum (Bleomycin A5). The dose-effect relationship for different doses of pingyangmycinum (0.05, 0.1, 0.2 mg) on the lung injury, and the change of hydroxyprolin (Hyp), ceruloplasmin (CP), angiotensin converting enzyme (ACE), superoxide dismutase (SOD) in mice were investigated. The results showed that the pathological changes of alveolitis and pulmonary interstitial fibrosis were more severe, and mortality of the mice was increased when pingyangmycinum dose was increased. During 2-6 weeks of this experiment, Hyp, CP, ACE and SOD in serum and Hyp in lung tissue were increased in different degrees. However, the activity of SOD in lung tissue was decreased. The possible mechanism of this lung injury is also discussed.
