采用单克隆抗体、间接致敏红细胞花环试验法对复发性口疮(Recurrentaphthous ulcer,RAU)、胃癌及系统性红斑狼疮(System ic lupus erythem atosus,SLE)患者外周血WuT3、WuT4、WuT8 及T4/T8 比值进行检测。结果:胃癌患者WuT3、WuT4 低于对照组( P< 0.05),WuT8 高于对照组,T4/T8 比值明显低于对照组( P< 0.001)。SLE组患者WuT8 较对照组低下,T4/T8 比值增高( P< 0.05)。RAU组患者WuT3 低于对照组,WuT8 高于对照组,T4/T8 比值下降( P< 0.05)。认为:①胃癌的发生是机体总的细胞免疫处于低下无能状态,不能对肿瘤进行正常的免疫监视及免疫应答。②SLE的发病与WuT8 功能降低有关,其导致自身反应细胞发生脱抑制而功能亢进。③RAU 的发生是因WuT8 细胞功能增强,致使Tc细胞的作用增强,其直接攻击粘膜靶细胞造成粘膜坏死、溃疡  相似文献
