Intestinal lymph drainage reduces lung tissue cell apoptosis of hemorrhagic shock rats / 中国基层医药

ABSTRACT

ObjectiveTo explore the effect of the intestinal lymph drainage on lung tissue cell apoptosis in rats with hemorrhagic shock after resuscitation,rich ALI intestinal lymphatic pathway theory.MethodsTUNEL method was used to determine the apoptosis of lung tissue cells,the brown nuclei were apoptotic cells.SABC was used to determine Bcl-2 and Bax protein expression.ResultsThe shock group and shock + drainage group lung tissue cell apoptosis rate were significantly higher than those in the sham operation group,but the shock + drainage group,the apoptosis of lung tissue cells was significantly lower than the shock group.Sham operation group showed Bcl-2,Bax protein of expression; In shock group,lung tissue cell Bcl-2 expression was significantly lower than the sham operation group,the Bax expression was significantly higher than that in the sham operation group; In shock + drainage group,lung tissue cells shored enhanced expression of Bcl-2,Bax expression was reduced,and the shock + drainage group lung tissue cell Bcl-2 expression was significantly higher than that in the shock group,the expression of Bax was significantly lower than the shock group.ConclusionThe excessive apoptosis of lung tissue cells was one of the mechanisms of lung injury after shock.Intestinal lymph drainage could reduce lung tissue cell apoptosis,the mechanism invdved the regulation of Bcl-2/Bax protein expression.
