艾灸命门对督脉循行线上皮肤温度的影响

目的:观察艾灸命门对督脉主要经穴皮肤温度的影响。方法:对36例健康志愿者艾灸命门穴,应用红外热像仪采集背部热像图,观察自然状态下和艾灸命门穴30min命门左右旁开及腰阳关、命门、中枢、至阳、身柱及大椎的皮肤温度变化。结果:艾灸命门时,督脉的循经红外辐射轨迹(IRRTM)在原有基础上显示更为清晰规整,督脉的整体温度升高。艾灸命门后,命门穴温度高于左右旁开对照点(P0.001)。艾灸命门穴30min后,督脉循行线上的至阳、中枢、命门、腰阳关穴位温度明显升高(P0.01)。艾灸命门时,督脉线上穴位升温幅度从高到低依次为命门、腰阳关、中枢、至阳、大椎、身柱。结论:督脉作为阳脉之海,灸之对督脉IRRTM有良好激发作用,可以有效提高督脉整体皮肤温度。

Changes of Skin Temperature of Acupoint Regions of the Governor Meridian after Moxibustion Stimulation

Objective To observe changes of skin temperature along the Governor Vessel(GV)after moxibustion stimulation.Methods A total of 36 healthy volunteer subjects were recruited in the present study.The skin temperature of Mingmen(GV 4),Dazhui(GV 14),Shenzhu(GV 12),Zhiyang(GV 9),Zhongshu(GV 7),Yaoyangguan(GV 3)regions and their bilateral control sites(1.5 cunlateral to GV 4)was detected by using a Thermo Tracer TH 9100.Results Following moxibustion stimulation of GV 4region,a marked infrared radiant track along the central part of the back covering the GV was observed in the healthy volunteer subjects,and the skin temperature levels of both GV 4and its bilateral control points were significantly increased(P<0.001).The skin temperature of GV 4was remarkably higher than those of both left and right control points(P<0.001).After moxibustion stimulation,the average skin temperature levels of GV 9,GV 7,GV 4and GV 3were all up-regulated in comparison with pre-moxibustion(P<0.01).Conclusion Moxibustion stimulation of Mingmen(GV 4)can induce an infrared radiant track along the central part of the back covering the GV and raise skin temperature of acupoint areas of the GV.
