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<0.01) at 4h
8h
16h.In the middle and high dosage groups and DXM group
Th1/Th2 was getting higher at 8h and 16h compared with that of the model group with a significant difference(P<0.05 or P<0.01).Conclusion Lianggesan Decoction corrects the Th1/Th2 imbalance
which might be one of the mechanisms in protecting the acute lung injury.
