摘要:Lung fibrosis was induced in rats by exposing them to fractionated irradiation, bleomycin instillation into the lung, or paraquat treatment. Lung lipid peroxides, serum lipid peroxides, and lung collagen hydroxyproline were found to be significantly elevated (>100%) in rats after exposure to these agents over a period ranging from 25 days to 60 days. Antioxidants curcumin, ellagic acid, bixin, and α-tocopherol reduced significantly the serum and lung lipid peroxides. Consequent to the decrease in peroxides, lung collagen hydroxyproline was reduced to almost the normal level in these animals. These results indicate the usefulness of the above non-toxic antioxidants in conditions of lung fibrosis produced by various xenobiotic agents.
