[摘要]目的 探讨大鼠内毒素性急性肺损伤(acute lung injury,ALI)时应用丙泊酚后处理对肺组织磷酸化c-Jun氨基末端激酶(phospho-c-Jun terninal kinnase,p-JNK)的影响。 方法 96只雄性SD大鼠按数字随机表法分为4组(每组24只):生理盐水对照组(A组);内毒素[有效成分为脂多糖(lipopolysaccharides,LPS)]致伤组5 mg/kg尾静脉注射,B组);丙泊酚低剂量治疗组(丙泊酚2 mg/kg诱导后,4 mg・ kg-1・h-1维持,C组);丙泊酚高剂量治疗组(丙泊酚4 mg/kg诱导后,8 mg・ kg-1・h-1维持,D
组)。每组大鼠均在诱导后1、2、3、4 h时经放血处死大鼠(采用放血法随机活杀6只大鼠并留取肺组织标本),用免疫蛋白印迹
法(western -blot)和免疫组织化学法(immunocytoche-mical,IHC)检测肺组织c-Jun氨基末端激酶(c-Jun terninal kinase,JNK)磷
酸化的水平。 结果 western-blot和IHC显示B、C、D3组各时点肺组织JNK磷酸化水平较A组均显著升高(P=0.02~0.03<0.05或P=0.006~0.008<0.01),3h时western-blot达到了322±32,比A组相同时点有显著升高(P=0.002<0.01);IHC显示p-JNK为21.7±4.4,比A组也有明显的增多(P=0.003<0.01)。C组和D组大鼠的肺组织p-JNK与B组各时点相比有显著的降低(P=0.03 ~0.04<0.05或P=0.007~0.008<0.01),western-blot显示3 h p-JNK时分别下降到了235±26和179±21,而IHC则降低至15.1±3.1
和12.3±1.7。D组p-JNK与C组相比,在诱导后3h也有显著地下降,其余各时点相比无统计学意义。结论 丙泊酚可以显著抑制内毒索性ALI大鼠肺组织中p-JNK的表达。

Objective To investigate the effects of c -Jun terninal kinase (JNK) activation post -trested by propofol on
lipopolysaccharide-induced acute lung injury. Methods Ninety six male SD rats were randomly divided into 4 equal groups (n=24) :the control group(0.9% sodium chloride group); Lipopolysaccharides (LPS) group (intravenous injection of LPS 5 mg/kg); low dose of propofol group (2 mg/kg induced and 4 mg・kg1・h-1 maintained); large dose of propofol group (4 mg/kg induced and 8 mg・kg-1 ・h-1
maintained). Six rats were killed at each time point after LPS intravenous administration (saline in group A)and the lungs were harved and the activation of Phospho c-Jun terninal kinase (p-JNK) was recorded in the lung tissues by the method of western-blot
and Immunocytoche-mical (IHC). Results Western-blot and IHC shown that the activation of JNK in the lung tissues increased
significantly after LPS administration (P=0.02-0.03<0.05 or P=0.006-0.008<0.01 ) . The number ofp-JNK was 322±32 and 21.7±4.4 shown by western-blot and IHC at the time point of 3 h after LPS administration. The p -JNK at all time points declined significantly
after treatment with propofol in group C and group D and the p-JNK declined to 235±26 and 179±21(western-blot) and 15.1±3.1 and 12.3±1.7(IHC) at the time point of 3 h. Compared with group C, p-JNK declined more than those in group D at the time point of 3 h after after LPS administration. Conclusion Treatment with propofol can significantly attenuate the p -JNK expression in LPS-
induced acute lung injury in rats.
