经脉线与非经脉线相关组织导热性的比较

Comparison of the thermal conductivity of the related tissues along the meridian and the non-meridian

目的:比较与经脉线和非经脉线相关组织的导热性有无不同。方法:应用红外热像仪系统,对40名健康成年志愿者进行观察。结果:在经脉线上的穴位或非穴位处加热,皮温反应可沿经双向扩展,长者几乎可以通达该经脉的全程;而在非经对照部位加热,皮温的反应仅限于局部,没有明显的扩散,更没有确定的方向。对前臂内侧经脉线和非经脉线的皮肤同时加热,皮温的反应沿经扩展的速度明显快于非经部位,随着加热时间的延长,逐渐形成了三条与古典手三阴经路线基本一致的红外辐射轨迹。结论:经脉线上相关组织的导热性较非经对照部位好,而且有明确的方向性,两者的物理学特性确有不同。

Objective To compare the thermal conductivity ot the related tmsues along meridian hne anti non-me-ridian area. Methods Forty healthy volunteers were observed with a infrared thermal imaging system. Results During heating the acupoint or the non-acupoint along the meridian line, the velocity of spreading of the temperature- increasing response along the meridian line was more easy and rapid, with a definite direction. However, during heating the non-meridian spots, the change of temperature was confined to the local area, with no definite direction. The spreading of skin temperature response along the meridian line was more rapid than the non-meridian area during both the two were heated simultaneously, and finally, 3 infrared radiant tracks along the meridian courses conformed basically with that of the classical three yin- meridians of the hand appeared. Conclusion The thermal conductivity of the related tissues along the meridian line is better than that of non-meridian area and has definite direction, with differences in physical characteristics between them.
