Abstract: 目的:观察环孢菌素A(CSA)对哮喘气道炎症的影响.方法:将健康豚鼠随机分为健康组、哮喘组与CSA组,分别收集肺泡灌洗液计数细胞总数及分类,应用酶联免疫法(EUSA)检测血清sIL-2R和IL-5水平,透射电镜观察气道上皮细胞损伤及粘膜内嗜酸粒细胞浸润程度,将3组结果进行比较.结果:哮喘组豚鼠BALF细胞总数及分类、血清sIL-2R、IL-5水平明显高于健康组,CAS组比哮喘组明显降低.透射电镜见健康组豚鼠气管与支气管粘膜上皮正常,哮喘组有明显炎性改变,CSA组改变轻微.结论:CSA对哮喘气道炎症具有明显抑制作用,其机理可能与抑制淋巴细胞活化,减少IL-4、IL-5的合成有关.
