ABSTRACT
Objective To observe the change of Bax/Bcl-2 of pulmonary epithelium on endotoxin-induced acute lung injury.Methods 60 rats were randomly divided into two groupscontrol group,LPS group.After giving LPS 5mg/kg or NS 4 hours,the respiratory rates and partial pressure of arterial oxygen were measured.Then the rats were killed and the ratios of W/D of lung tissue were detected.The Bcl-2-positive cells and Bax-positive cells were measured by using immunocytochemistry.Results After giving LPS,the respiratory rates and the ratios of W/D of lung tissue were higher than those in control group.Partial pressure of arterial oxygen was lower than that in control group.Bcl-2-positive cells had no significant difference between two groups,and Bax-positive cells were higher than those in control group.Conclusion The increasing of Bax-positive cells induced the apoptosis might be the mechanism of ALI.
