以压迫阻滞针效定位的方法检测针刺时体表出现的经络轨迹

本文以视网膜电图(ERG)为指标:机械压迫为手段,观察针刺时体表出现的经络轨迹。针刺穴为合谷。压迫穴分别为温溜、手三里、曲池、臂臑和肩髃,并以压迫上述穴位的两侧旁开部位作为对照。观察对象为5例感传显著者和5例无感传者。结果表明:当机械压迫施加在经线上,各平面的 ERG 振幅变化不明显,而压迫非经线时,则ERG 反应都明显大于压迫经线时,二者对比有非常显著的差异。从而成功地检测出针刺合谷时体表出现的经络轨迹,其路线与大肠经的循行路线基本一致。经络轨迹的测定为经络循行路线的客观检测开辟了一个新的途径。

LOCALIZATION OF THE MERIDIAN TRACK OVER BODY SURFACE BY THE METHOD OF BLOCKING THE ACUPUNCTURE EFFECT WITH MECHANICAL PRESSURE

Plotting out the meridian course with objective methods is one of the import- ant projects in the research of meridian at present,Therefore,selecting a proper indication to plot out the m(?)ridian track over the body surface during acupuncture is significant for elucidating the essence of meridian.The purpose of this paper was to plot out the Large Intestine Meridian track by blocking the acupuncture effect with mechanical pressure,when electroretinogram (ERG) was taken as a responsive indication.The plotting out the track was carried out on 5 subjects with marked propagated sensation along meridians (PSM) and 5 without PSM.The pressure was applied on Wenliu (LI 7),Shou- shanli (LI 10),Quchi (LI 11),Binao (LI 11) and Jianyu (LI 15) respectively, when Hegu (LI 4) was punctured.Under such condition the variation of ERG amplitude decreased markedly or even disappeared.But the variation rate of ERG amplitude was still distinctly increased when the pressure was applied on both sides of any above points.The difference is highly significant (P<0.01). The results revealed that the meridian track over the body surface during acupuncture could be plotted out not only in the subjects with marked PSM, but also in those without PSM,when the proper objective indication was used. Its course basically coincided with that of the meridian described in the books of traditional Chinese medicine.Now it is safe to say the meridian track over the body surface is existed in human in common.It provides a new approach to plot out the meridian course with objective methods and opens up broad prospects for further application.
