针刺对经脉穴位微循环血流量的影响

目的:探讨针刺对经穴及非经穴微循环血流量的影响及其机制。方法:应用激光多普勒血流仪(LaserDopplerFlowmeter,LDF)检测30例健康人针刺前后十二经脉循经经穴、经穴旁开和在经非穴微循环血流量的变化。结果:人体穴位血流量高于经穴旁开和在经非穴(P<0.05);针刺时,十二经脉循经线上经穴的微循环血流量明显增加,经穴旁开的血流量增减不明显,两者相比有显著性差异(P<0.05);针刺时,十二经脉在经非穴的血流量虽有增加,但无统计学意义,经穴的血流量与在经非穴的血流量相比,具有显著性差异(P<0.05)。结论:经络的循经感传现象是可以客观检测的,微循环检测可以为经络的生理机制研究提供更多信息。

Effects of Acupuncture on Blood Flow of Meridional Point

Objective: To explore the effects and mechanisms of microcirculation blood flow(MBF) by manual acupuncture stimulation on meridional point and non-meridional point.Method: The Changes of MBF of Twelve Classical Channels' meridional point, para-meridian point and non-meridional point were measured in 30 healthy subjects by laser Doppler Flowmeter before and after acupuncture. Results: MBF of meridional point was much higher than that of para-meridian point and non-meridional point (P<0.05). After acupuncture, MBF of meridional point obviously increased in the Twelve Classical Channels,however, MBF of para-meridian point did not produce significant response.The difference of variation of MBF between meridional point and control was significant (P<0.05). After acupuncture, MBF of non-meridional point in the Twelve Channels increased, but it showed no significant difference(P>0.05).There was an evident difference between MBF of meridional point and that of non-meridional point.Conclusion: Our results proved that the phenomenon of Propagated Sensation along Meridian could be objectively detected, moreover, the detection of microcirculation could provide more information for studying the physiological mechanism of Meridians.
