作者对25名活动性、15名非活动性系统性红斑狼疮(SLE)、5名血清阳性的风湿性关节炎患者,并以26名健康人作对照,以自然花瓣形成和补体结合花瓣形成试验作为指标,观察其加胸腺素(从小牛胸腺制备)、不加胸腺素以及加脾注射液F_5,对花瓣形成作用的影响。实验结果表明,活动性与非活动性SLE与正常对照组比较,活动性SLE患者自然花瓣形成率明显下降(P<0.01),其补体结合花瓣形成率下降也较明显(P<0.05),而其“无效”细胞(Nullcells)百分率则明显增加(P<0.01),非活动性SLE患者的“无效”细胞数虽亦增加,但与正常对照组相比无 The author of 25 active, 15 patients with inactive systemic lupus erythematosus (SLE), 5 seropositive patients with rheumatoid arthritis, and 26 healthy controls, with natural petal formation and complement fixation with petal formation test As an indicator to observe the effects of adding thymosin (prepared from calf thymus), without thymosin, and adding spleen injection F_5 on petal formation. The experimental results showed that the rate of natural petal formation in active SLE patients was significantly lower than that in normal controls (P <0.01), and the rate of complement fixation and petal formation decreased significantly (P <0.05) The percentage of “null” cells increased significantly (P <0.01), while the number of “inactive” cells in inactive SLE patients increased, but compared with the normal control group
