Research Abstract

Idiopathic pulmonary fibrosis(IPF) is thought to involve inflammatory infiltration of leukocytes, lung injury induced by reactive oxygen species(ROS), in particular superoxide anion, and fibrosis(collagen deposition). Intravenous administration of PC-SOD suppressed the bleomycin-induced increase in the number of leukocytes in bronchoalveolar lavage fluid. Bleomycin-induced collagen deposition and increased hydroxyproline levels in the lung were also suppressed in animals treated with PC-SOD, suggesting that PC-SOD suppresses bleomycin-induced pulmonary fibrosis.
