目的 :应用红外辐射成像技术显示人体体表循经分布的红外辐射轨迹 (IRRTM )

并对其形成机理进行初步探讨。方法 :观察对象为 3 0 0名健康成年志愿者

以红外辐射示踪仪显示人体体表的IRRTM

并对与其相关组织的温度、氧分压和微循环状态进行了检测

分析其产生的原因。结果 :①IRRTM是在人群之中普遍存在的一种正常生命现象

可见之于十四经的每一条经脉 ;②IRRTM的皮肤微循环的灌注量高于其两侧对照区

它的形成与皮肤微循环状态密切相关 ;③冷负荷实验的结果提示

IRRTM的热源位于皮下一定深度的组织之中 ;④经脉线下深部组织的温度高于其两侧对照区 ;⑤经脉线下深部组织的氧分压也明显高于其两侧对照区 ;⑥针刺时经脉线上的能量代谢进一步增强

这种效应还可被压迫经脉线所阻断。结论 :①IRRTM的形成与皮肤微循环密切相关

但其主要热源位于皮下一定深度的组织之中

该处能量代谢活跃

组织温度较高 ;②经脉线下的相关组织可能是一条具有多元结构的物质、能量和信息转换和传递的通道

这一通道的实体包括了多种已知的组织

可能还有一些未知的因素参与

它的热学特性与其周围的组织有明显的不同 ;③上述实验结果为进一步弄清与经脉循行路线相关的物质基础、阐明经络的实质提供了一方面的依据Objective: To display the infrared radiant track along meridian course(IRRTM) over the human body surface and to explore the mechanism of its formation. Methods:Three hundreds healthy volunteer subjects were observed. IRRTM was displayed by a thermal tracer. At the same time

the microcirculation of the skin

the temperature and PO 2 in deep tissues along the meridian course were determined. Results: ①IRRTM was really a normal biological phenomenon of human body and exists in each of the 14 meridians. ②The results of cooling test demonstrated that the thermal source of IRRTM was located in the deep tissues underneath the skin. ③The perfusion volume of the microcirculation in the skin along IRRTM was higher than its bilateral non meridian areas. ④The temperature and PO 2 in the deep tissues along IRRTM were also higher than those of its bilateral non meridian areas. ⑤ Metabolism of oxygen in the related tissues along IRRTM increased during acupuncture stimulation

and such response could be blocked by pressing the corresponding meridian course. Conclusion: ①The formation of IRRTM was closely related to the microcirculation of the skin

but its main thermal source was located in a certain deeper tissues underneath the skin where the temperature was higher and the oxygen metabolism was more active. ②The meridian course may be a channel with poly structures for the transformation and transmission of materials

energy and bio signals. This channel consists of several kinds of known tissues

and some unknown factors may also be involved. ③The above results may provide a basis for further clarifying the materials involving meridian running course and the essence of meridian from one aspect.
