摘要:目的 观察艾灸新西兰家兔命门穴对督脉主要经穴皮肤温度的影响。 方法 使用红外热像仪分别采集10只家兔背部热像图,观察自然状态下、艾灸命门穴30 min时命门、大椎、身柱、至阳、中枢、腰阳关及命门左右旁开皮肤温度变化情况。结果 艾灸命门30 min时,督脉的整体温度升高,有显著性差异(P<0.05);命门穴温度高于左右旁开对照点(P<0.05);督脉循行线上的中枢、命门、腰阳关穴位温度明显升高(P<0.05),而大椎、身柱的温度略有下降,但无显著性差异。结论 命门作为原气发动之机,生命活动的动力,灸之可以有效提高督脉整体皮肤温度,促进督脉气血运行。

【Abstract】Objective: To observe the effect of moxibustion at the Mingmen point on the skin temperature of New Zealand rabbits on the line of governor meridian. Methods: The thermal images of the backs of 10 rabbits were respectively collected with an infrared thermal imaging camera. The skin temperature changes of the rabbits at points of Mingmen, Dazhui, Shenzhu, Zhiyang, Zhongshu, Yaoyangguan and the left and right sides of Mingmen at 30 minutes of moxibustion were observed in the natural state. Results: At 30 minutes of moxibustion at the Mingmen acupoint, the overall temperature of the Governor Meridian increased, with a significant difference(P<0.05) and the temperature of Mingmen acupoint was higher than that of the left and right side control points(P<0.05). The temperature of Zhongshu, Mingmen, Yaoyangguan on the line of the Governor Meridian points increased significantly(P<0.05), while the temperature of Dazhui and Shenzhu decreased slightly, but there was no significant difference. Conclusion: Mingmen is the engine of the original qi and the driving force of life activities and moxibustion at it can effectively increase the overall skin temperature of Governor Meridian and promote the circulation of qi and blood in the Governor Meridian.

红外成像技术目前已广泛应用于经络现代研究。魏海燕等[1-2]用红外辐射观察到家兔在不同生命状态有不同温度,张栋等[3]发现胆囊炎家兔体表有循经高温线显示,窦思东等[4]发现腧穴区具有高温特性,经脉线上穴区的ATP能量代谢及导热性高于非穴区。本课题组以往研究发现[5-7],采用红外热像仪可观察到自然状态下十四经脉的循经红外辐射轨迹,其中督脉循行轨迹最为典型,而且加热也易于诱发其显现。本课题在以往工作基础上,通过观察艾灸新西蘭家兔命门穴后督脉皮肤温度变化,并比较督脉线上各主要穴位皮肤温度变化,为进一步深入研究动物经脉能量代谢提供依据。
