Abstract

Background & Objective : Idiopathic Lung Fibrosis(IPF) is chronic fibrotic interstitial pneumonia. The pathogenesis is unclear. Fritillariae Rhizoma is the most commonly used antitussive and expectorant Oriental medicinal herb. The effects of Fritillariae Rhizoma on bleomycin-induced lung fibrosis is here evaluated. Material and Methods : Fritillariae Rhizoma extract was daily given to the normal rats, control(bleomycin) rats and treated(bleomycin and Fritillariae Rhizoma) rats at 9.0 mg per body weight 10g for 14 days. 14 days later, the change in Leukocyte count and percentages were observed, as well as IFN-gamma and 1L-4 in BALF, and the change in Semiqualitative histological index(SHI). Results : Compared to control rats, Fritillariae Rhizoma treated rats showed a lower leukocyte count(P<0.05) lymphocyte, neutrophil percentage, SHI(p<0.05), IFN-gamma and IL-4(p<0.05) in treated rats. Conversely, macrophage percentages went higher(p<0.05) in treated rats. Conclusion : This study supports a role for Fritillariae Rhizoma in reducing the maintaining inflammatory cells and cytokines in rats with bleomycin-induced lung fibrosis and in the reduction of fibrosis tissues. Further research is needed in order to develop an effective treatment for lung fibrosis.
