利用酶联免疫吸附测定(ELISA)方法检测了65例弥漫性结缔组织病患者血清可溶性白细胞介素2受体(SIL-2R)水平。系统性红斑狼疮(SLE)、类风湿关节炎(RA)、皮肌炎活动期血清SIL-2R平均水平分别为0.46 U/L、0.53 U/L、0.46 U/L,较健康人0.25 U/L明显增高。1例混合性结缔组织病和1例硬皮病分 Serum soluble interleukin 2 receptor (SIL-2R) levels were measured in 65 patients with diffuse connective tissue disease by enzyme-linked immunosorbent assay (ELISA). The average serum levels of SIL-2R in patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and dermatomyositis were 0.46 U / L, 0.53 U / L and 0.46 U / L respectively, L was significantly higher. 1 case of mixed connective tissue disease and 1 case of scleroderma
