《内经》中关于刺法之论述很多

并进行了分类

有九刺、十二刺、五刺等。《灵枢、官针》篇中更有巨刺法(九刺中之一种)。“巨刺者

左取右、右取左”

是指在病取右

右病取左。我们的工作曾初步观察到当刺激穴位时

同侧穴位灌流液中乙酰胆硷(ACh)含量增加。巨刺时到底对非针刺侧之组织有些什么影响

对非针刺侧之神经末梢之递质产生哪些变化

是值得探索的。本试验系前文工作之一部分

观察了巨刺对于对侧相应部位的穴位灌流液Ach含The present investigation was intended to ascertain whether the method of selecting acupunctur.points will exert infIuence over the ACh content of acupuncture point. The effect of Ju Ci on ACh cont-ent of the fluid perfused from the acupuncture point of the opposite side was observed and comparedwith that from the acupuncture point of the same side. It was revealed that the mean value of AChreleased from the acupuncture point of opposite side was lower than that from the same side. Their dif-ference bad highly statistical significance (t=3.192

P<0.01). Results showed that the ACh content ofacupuncture points may be influenced by different methods of selection and suggested that the methodsof selecting points for needling may be important for the purpose of getting better analgesic or therape-utic effect of acupunture.
