Objective To investigate the molecular mechanism of inflamation development and anti-inflamation response of Lianggesan Decoction(Decoction for cooling the chest) on endotoxin-induced acute lung injury rats. Methods The rat models with acute lung injury were made by lipopolysaccharide(LPS) through intravenous injection.The high,middle and low dosage of Lianggesan Decoction were given by gastric perfusion and compared with dexamethasone(DXM).The contents of Th1 and Th2 in peripheral blood and bronchoalveolar lavage fluid(BALF) were measured at different time points to observe the changes in Th1/Th2.Results In the model group,Th1/Th2 in peripheral blood and BALF was gradually lowering,the difference was significant compared with those of the blank group(P

Objective:To search the effects and possible mechanisms of Lianggesan on the acute lung injury(ALI) rat induced by endotoxin. Methods: Endotoxemia was induced by intravenous lipopolysaccharide (LPS,5 mg/kg), then treated with Lianggesan. The levels of TNF-?, IL-1?and IL-10 in serum and wet-to-dry weight ratio of lung were detected. Results:In LPS group the levels of TNF-? began to increase at 1h, which reached the peaks at 2h(P
