摘要 目的探讨白细胞介素10(IL-10)对失血性休克大鼠肺的保护作用。方法24只雄性SD大鼠随机分为3个组,每组8只:假失血性休克对照(Control)组,休克(Shock)组,IL-10+Shock(IL-10)组。测定各组动脉血氧分压(PaO2),pH值,二氧化碳分压(PaCO2),肺湿/干重比值,测定血清丙二醛(MDA)含量以及超氧化物歧化酶(SOD)活性;检测支气管肺泡灌洗液(BALF)中性粒细胞比例及肺通透性指数,采用ELISA法测定灌洗液上清液及血清中IL-1I、L-6、TNF-α含量。结果与Shock组相比,IL-10组PaO2和pH值升高、PaCO2降低(P<0.01),IL-10组大鼠肺湿/干重(W/D)、支气管肺泡灌洗液中上清及血清中IL-1I、L-6、TNF-α含量均低于Shock组(P<0.01)。结论给于IL-10能够抑制IL-1I、L-6、TNF-α激增并减轻失血性休克大鼠的肺部炎症反应。
