作者研究98例风湿性舞蹈病(年龄5～14岁)和同龄健康儿童40人(对照组)的T-和B-免疫系统。舞蹈病的严重性与风湿病变的活动性相一致,其中轻型47例、中型34例和重型17例。结果如下:1.在对照组中T-花环形成细胞(T-POK)相对数为30.5±1.7%,绝对数为60.2±39.6/mm~3。神经风湿病患者中出现T-POK 相对与绝对数量减少,相应为23.5±1.7%与46.0±36.0/mm~3(P<0.01)。2.通过刺激植物血凝素时的成淋巴细胞转化 The authors studied T- and B-immune systems in 98 rheumatic chorea (aged 5-14 years) and 40 healthy children of the same age (control group). The severity of chorea was consistent with the activity of rheumatoid lesions, of which 47 were light, 34 were medium and 17 were heavy. The results were as follows: 1. The relative number of T-POK in control group was 30.5 ± 1.7% and the absolute number was 60.2 ± 39.6 / mm ~ 3. The relative and absolute numbers of T-POK in patients with neuro-rheumatism decreased by 23.5 ± 1.7% and 46.0 ± 36.0 / mm 3, respectively (P <0.01). 2.
