循经低流阻通道组织液压的初步观察

Preliminary observation on the interstitial fluid pressure of low hydraulic resistance channel along meridians

目的测量循经低流阻通道与周围的组织液压,观察其差异及变化情况。方法在麻醉的小型猪上,使用连续流阻测量仪测出低流阻点和非低流阻点,然后采取针中芯方法测量组织液压。结果统计结果表明,小型猪胃经、肾经和任脉的低流阻通道平均压力均显著低于旁开的高流阻区域,其压力差分别为1.06、0.70、3.69 mmHg(1 mmHg=0.133 kPa),总压力差为1.44 mmHg,压力梯度为1.44～2.88 mmHg/cm。在一些低流阻点上发现了与呼吸频率一致的压力波。结论外周皮下组织中存在着指向经脉低流阻通道的压力差,可能构成组织液向经脉流动的动力。

Objective To measure the interstitial fluid pressure（IFP） on low hydraulic resistance channel along meridians and observe the difference and fluctuation.Method Low hydraulic resistance points（LHRP） and non-LHRP were measured on anesthetized mini-pigs by a scanning hydraulic resistance measuring device.The IFP was then measured by wick-in-needle method on these two regions.Results The stomach meridian,kid-ney meridian and conceptual vessel meridian on mini-pigs were measured.The IFP were significantly lower than non-LHRP region on the above three meridians（P 0.05）,the differences of which were 1.06,0.70,3.69 mmHg respectively with the total pressure difference of 1.44 mmHg and pressure gradient of 1.44 ～ 2.88 mmHg/cm（1 mmHg =0.133 kPa）.Conclusions Among the peripheral subcutaneous tissues,there exists a difference of IFP toward the meridian which may drive the flow of interstitial fluid toward the meridians.
