本文以单克隆抗体间接免疫荧光法检测20例活动性患者外周血T细胞及其亚群,15 例正常人作为对照。结果是Leu2a~+、Leu3a~+和 Leu4~+细胞绝对数和百分率均明显低于正常人,而Leu3a~+、Leu2a~+比值正常。结合文献及我们以往资料提示本病免疫功能异常在细胞免疫,而其中T_H 细胞降低为其主要方面。不同组织部位损害与T细胞亚群之间虽分别有一定联系,但无规律性。 In this paper, monoclonal antibody indirect immunofluorescence assay of 20 patients with active T cells and their peripheral blood subsets, 15 normal subjects as a control. The results showed that the absolute number and percentage of Leu2a ~ +, Leu3a ~ + and Leu4 ~ + cells were significantly lower than normal, while the Leu3a ~ +, Leu2a ~ + ratio was normal. Combined with the literature and our previous data suggest that the abnormal immune function of this disease in cellular immunity, in which T_H cells decreased as its main aspect. Different tissue parts and T cell subsets, although there is a certain relationship between the damage, but no regularity.
