【摘要】 目的探讨休克时肺组织内核转录因子-кB(NF-кB)、细胞间粘附分子-1(ICAM-1)和白细胞介素-6(IL-6)水平的变化及参附注射液对三者的影响。方法健康SD大鼠33只分成3组:手术对照组(C组)、休克组(S组)和参附治疗组(SF组),每组11只。采用股动脉放血复制大鼠休克模型。复苏18h后活杀取肺组织,免疫组织化学法检测肺组织NF-кB活性和ICAM-1水平,ELISA检测大鼠肺组织IL-6水平。结果S组NF-кB活性、ICAM-1和IL-6水平显著高于C组和SF组(P<0.01),且SF组NF-кB活性和IL-6水平高于C组(P<0.05)。结论参附注射液能抑制休克相关性肺损伤NF-кB活性和降低ICAM-1和IL-6水平,减轻休克导致的肺组织损伤。更多还原

【Abstract】 Objective To study NF-кB activity,ICAM-1 and IL-6 level following shock-associated lung injury and the effect of Shenfu injection on them in rats.Methods 33 SD rats were randomized into three groups each consisting of 11 rats:Sham-operated control group(C group),shock group(S group),Shenfu injection group(SF group),shock models were induced by hemorrhaged from the femoral artery to the mean arterial pressure of 35 mmHg,1 hour later,S group were resuscitated with twofold volume lactated Ringer′s solution,whereas SF group with Shenfu injection.The activity of NFкB and the level of ICAM-1 in lung were detected by immunohistochemical technique,and the level of IL-6 in lung were measured by ELISA method.Results The activity of NF-кB,the level of ICAM-1 and IL-6 in S group were significantly higher than those in C and SF group(P<0.01),and the activity of NF-кB,the level of IL-6 of lung tissue in SF group were higher than those in C group(P<0.05).Conclusion Shenfu injection can inhibit the activity of NFкB,decrease ICAM-1 and IL-6 level,alleviate shock-associated lung injury.更多还原
