近年来

已有大量工作探讨中医中药在临床治疗中“扶正固本”的本质与免疫系统的关系。针灸对机体免疫功能的调整作用也有过一些研究

在细胞免疫方面以往多从对非特异性的细胞防护作用的影响进行观察

近年来

针灸对具有免疫活性的T

针灸疗法能促进或调整患病机体的免疫功能

增强机体抗病能力

说明针灸疗法在治疗医学中起到了积极的作The aim of this study was to observe effects of EA on cellular im- mune function in normal man further analyse the significance of acupunc- ture therapy in preventive medicine. The observations were carried out in health subjects divided into three groups: the first EA group

18 cases

both "Zusanli" and "Yanglingquan" acupoints stimulated by EA; The second EA group

8 cases

"Zusanli" and "Fenglong" acupoints were stimulated by EA; control group

9 cases were not stimulated by EA. The two EA groups received EA for 15 min- utes

once every other day

totalled 3 times. It was taken as the limit of strength of EA that the subjects felt local sense of numbness and fullness or conductible needling sensation. The percentages of T lymphocytes from peripheral blood of the sub- jects which ANAE reaction was belong to spot granular pattern and the change of activity of esterase within this kind of T cell were examined. The results were as follows: T lymphocytes with spot granular pattern were significantly increased after EA; the first EA group

p<0. 001; the second EA group

p<0. 01; but control group

p>0. 4. There were significant differences between EA groups and control group

p<0. 01; but there was no significant differen- ce between the two EA groups

p>0. 05. The esterase activity of T lymphocytes significantly increased in the two EA groups

p<0. 05

But had no significant change in control group. It was indicated that the T lymphocyte which ANAE reaction was spot granular pattern belonged to helped immune cell to bring immune function into play. So these results suggested that the function of physical immune active cell was increased by EA and could play an active role in increasing physical resistance.
