Abstract

|
A phytoformula containing the root barks of Morus alba, the fructus of Schizandra sinensis and the roots of Asparagus cochinchinensis (MSA) was prepared as a potential new herbal remedy, and its therapeutic potential for alleviating inflammatory lung conditions was examined. For in vivo evaluation, an animal model of lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice was used. With oral administration of 6 - 60 mg/kg, MSA potently and dose-dependently inhibited bronchitis-like symptoms in acute lung injury induced by intranasal treatment of LPS as judged by the number of cells in the bronchoalveolar lavage fluid (BALF) and histological observation. The inhibitory potency was comparable with that of dexamethasone. For in vitro assay, the effects on the production of proinflammatory molecules in lung epithelial cells and alveolar macrophages were examined. Although MSA inhibited IL-6 production in IL-1β-treated lung epithelial cells (A549) only at a high concentration (300 μg/ml), the formula strongly and concentration-dependently inhibited NO production in LPStreated alveolar macrophages (MH-S) at 20 - 300 μg/ml. Based on all of these findings, the new phytoformula MSA is suggested to have the potential to control inflammatory lung diseases including bronchitis, at least in part, by inhibiting inducible nitric oxide synthase-catalyzed NO production.
