[Comparison between governor meridian and its bilateral control points in microcirculatory blood perfusion in 53 volunteer subjects].
OBJECTIVE
To observe the difference of the microcirculation blood perfusion volume between the Governor Vessel (GV) running course and its bilateral control points in healthy volunteers.


METHODS
A total of 53 healthy volunteers were recruited in the present study. Cutaneous and muscular microvascular blood perfusion units (BPU) of Mingmen (GV 4), Jizhong (GV 6), Zhiyang (GV 9), Shenzhu (GV 12) and non-acupoint (at the 12th thoracic vertebra level) of GV and their bilateral non-meridian points (1 cm lateral to the above mentioned GV-acupoints and non-acupoint on both sides) were measured by using a Laser Doppler Flowmetry (PeriFlux 5000).


RESULTS
1) In comparison with bilateral control points, the cutaneous microvascular BPU values of Mingmen (GV 4), Jizhong (GV 6), Zhiyang (GV 9), Shenzhu (GV 12) and non-acupoint of GV Meridian were significantly higher (P < 0.01). 2) Compared with bilateral control points, BPU values of GV4, GV6, GV9, GV12 and non-acupoint of GV Meridian 1 cm, 1.5 cm and 2 cm beneath the skin were significantly higher (P < 0.05). No significant differences were found between the bilateral corresponding control points of GV4, GV6, GV9, GV12 and non-acupoint of GV in cutaneous BPU values, and between bilateral control points and GV4 in BPU values of deep (2.5 cm beneath the skin) tissues (P > 0.05).


CONCLUSIONS
Blood flow perfusion volumes in the skin and deeper tissues along GV are significantly higher than those of their bilateral corresponding control points, indicating that cutaneous microvascular blood flow and shallower muscular blood flow may be the heat source for forming infrared radiation trace along meridian (IRRTM) in our past studies.
