Abstract： 目的观察急性肺损伤小鼠T辅助淋巴细胞(TH)1/TH2的功能变化,探讨其在急性肺损损伤发生中的作用.方法小鼠腹腔注射脂多糖复制急性肺损伤模型.ELISA测定脾细胞培养上清液中干扰素(1FN)-γ、白细胞介素(IL)-4浓度,RT-PCR测定细胞因子mRNA表达.伊文思蓝荧光法测定肺血管蛋白渗出量.结果与正常对照组比较,急性肺损伤组动物肺组织中伊文思蓝渗出量、肺湿重/干重比均明显升高.在刀豆素A刺激的脾细胞上清液中,急性肺损伤组IFN-γ浓度显著下降(P＜0.01),IL-4明显升高(P＜0.01).RT-PCR显示急性肺损伤组动物脾细胞IFN-γ mRNA表达明显下降.结论急性肺损伤时,THl向TH2漂移,以抗炎症反应为主,调控抗炎反应是急性肺损伤治疗的关键.
