OBJECTIVE: Previous work showed that bleomycin (BLMA5) induces early pulmonary fibrosis in rats, increases lung NO, and increases endogenous NO with an increase in pulmonary collagen. Lung fibroblasts are the major cells that synthesize and secrete collagen in the interstitium. In order to explore the mechanism of NO promoting collagen increase, this experiment observed NO donor sodium nitroprusside (sodiumnit
