皮肤中儿茶酚胺类体液物质及毛囊与针刺效应的关系

通过对针刺穴位两端经络线上施加各种因素，观察了运动对针刺效尖的影响，进一步对其影响国素进行化分析和形态定位，结果表明，拔除经经毛囊和切断经线皮肤都可以明显地阻断针刺效应，而向皮肤经线切口滴加液体则能明显的改变再针刺效应，用高压液相色谱法检测到针刺可以使经线皮肤循经释放去甲肾上腺素，肾上腺素等儿茶酚胺类物质，其含量明显高于没有针刺的经线，用放射自显影技术观察到儿茶酚胺类物质的分布有明显的纵形线性特征

THE CATECHOLAMINE IN SKIN AND HAIR FOLLICLES ARERELATED TO THE EFFECTOF ACUPUNCTURE AND THE NATURE OF MERIDIAN

Comparing the influence on acupuncture effect (AE) by adding varuios factors to both sides of acupunctured point of meridian line,and then analyzing the positive factors by biochemical and morphological methods. The results indicate that AE can be depressed significantly by extracting out hair follicles or cutting down skin transversely at meridian line,but AE can reappear markedly while the sections of skin fill with tyriod's liquid.Analyzing liquid components in the sation of meridian after acupuncture by HPLC,and such kinds of noradrenaline and adrenaline were checked out,which are higher remarkably than that in blood or in non-acupunctured section of meridian besides,Observing the distribution of catecholamine in skin by autoradiography,and which locate as vertical zones or concentrated masses. and related to meridian line,More over,acupuncture can make the skin of extracted hair follicle to release catecholamine yet,but AE show an adverted change. The past workshave pointed out AE and PSC (the propagated sensation alone meridian or channels) can be blocked by subcutaneous injection of blocker of receptor a at meridian line,From all,conclude the releasings of catecholamine of skin after acupuncture and its action with some hair follicles is an important material foundation of AE,and an important natural feature of meridian line
