针刺时大肠经线下深部组织中氧分压与温度的实验观察

目的:观察常态下大肠经线下深部组织氧分压与温度及其在针刺过程中的变化,探讨与大肠经线相关组织的能量代谢特点。方法:沿大肠经循行线上取6个测试点并分为3组,并在各测试点内外1.5cm～2cm处各取1个非经对照点。测试深度为皮下1.5cm。连续同步记录氧分压与温度60min,观察其在电针前、电针合谷穴时及电针后的变化情况。结果:正常情况下沿大肠经循行线上测试点深部组织氧分压与温度均显著高于两侧非经对照点。电针合谷穴时,大肠经线上测试点氧分压显著降低;温度降低(统计学无显著差异)。电针后,氧分压非常显著降低;温度显著降低。而两侧非经对照点无显著的变化。结论:常态下大肠经循行线下深部组织中的能量代谢及温度都较其两侧非经对照部位旺盛,电针可以使沿经组织的氧利用率提高,能量代谢进一步增强,提示经脉可能是物质、能量与信息转换和传递通道。

Effect of Acupuncture on Partial Oxygen Pressure and Temperature of deep tissues along Large Intestine Channel in 30 Normal Volunteer Subfects

To observe the partial oxygen pressure and temperature of deep tissues along Lagre Intestine Channel under normal state and their variation during acupuncture,so as to probe the characteristics of energy metabolism in the deep tissues along Large Intestine track.Methods:Select 6 testing spots along Large Intestine Channel and group into 3 units,1.5cm beneath skin.Meanwhile two contrasting non-meridian points were adopted on the bilateral sides of each testing spot,1.5-2cm apart.The partial oxygen pressure a...
