ABSTRACT
Objective To investigate the protective effects of 1-hydroxy-2, 3, 5-trimethoxyxanthone (QGS) on acute lung injury of mice induced by ip lipopolysaccharide (LPS). Methods Mice were pretreated with QGS for 7 d. Murine models of acute lung injury were duplicated by injection of LPS 20 mg/kg intraperitoneally. In 12 h, the lung weight index was observed and the NO level in the bronchoalveolar lavage fluid (BALF) was measured with kits. The lung was also assessd for the expression of I-?B, inducible nitric oxide synthase (iNOS), and cyclooxygenase-Ⅱ (COX-2) using Western blotting analysis. Lung pathological changes were also observed by HE in each group. Results The lung weight index of injury lung in mice induced by LPS was decreased in 500 mg/kg QGS group (P
