中文摘要：

目的：进一步了解经脉线下深部组织温度的分布是否具有共同的规律，为探讨循经红外辐射轨迹的形成机理提供实验依据。方法：应用“组织温度测试仪”，对25名健康受试者心包经前臂段经线上郄门穴、郄门穴上2寸、郄门穴上4寸三点及其两侧旁开非经对照部位皮下1cm处深部组织温度进行检测，并进一步观察激光照射内关穴对它的影响。结果：心包经前臂段经脉循行线下深部组织温度多数高于两侧旁开非经对照部位，但也有低于两侧旁开非经对照部位者，有循经的表现；激光照射内关穴时经脉线上的温度上升较非经线快，停止照射后还可持续一段时间。结论：经脉循行线下深部组织温度与两侧旁开的非经对照部位显著不同，有循经分布的特点；激光照射穴位，温度反应有沿经传导的趋势，说明经脉组织可能具有较好的导热性。本实验结果为阐明循经红外辐射轨迹的形成机理提供一方面的实验根据。

英文摘要：

Authors want to understand if there is a common pattern for the distribution of temperature in the deep tissues underneath the meridian courses, in an attempt to work out some experimental evidences for elaborating the mechanism of Infrared radiant tracks along the meridian （IRRTM）. In the investigation, temperatures of deep tissues underneath the Pericardium Meridian course of forearm were taken. The effects of irradiating Neiguan （PC6） on the deep tissue temperature were also observed. In the study, 25 healthy volunteers were observed. The temperatures of deep tissues of 3 points along the pericardium meridian forearm, namely Ximen （PC4） , 2 Cun above Ximen, and 4 Cun above Ximen were measured using an apparatus with 3 needlike temperature transducers. The effects of irradiating Neiguan （PC6） were further observed. It is found that in most cases, the temperatures of deep tissue of above 3 points along the Pericardium meridian course were higher than the bilateral controls, though the temperatures of deep tissue along the meridian course could be lower than the bilateral controls in some other cases. The meridian - like distribution of deep tissue temperatures is basically significant. The deep tissue temperature along the meridian rose more rapidly than the non - meridian controls during laser irradiation, and could be sustained for some time. It is concluded that the deep tissue temperature along the Pericardium meridian course is noticeably different from the bilateral non - meridian area, showing a meridian - like pattern in most subjects observed. The thermal conductivity of the tissues along the meridian course is better than that of the non - meridian area. It is obvious that the thermal energy in deep tissues can teransmit along the meridian course. This can be an important part of IRRTM formation.
