月经前后手三阴经原穴伏安特性

目的:观察健康女性月经前后穴位伏安特性的变化规律,研究穴位伏安特性与人体气血变化的关系,创建气血变化定量研究新方法。方法:应用自制的穴位伏安特性计算机检测系统对健康女性月经前、月经时及月经后手三阴经原穴太渊、大陵、神门进行伏安特性检测。结果:月经前后太渊、大陵、神门穴均有部分扫描点电阻发生了明显的变化,以大陵最为明显、太渊次之、神门最不明显,差异均有统计学意义。在三个穴位所有电阻发生明显变化的扫描点中,穴位电阻随月经进程变大的比率为70.6%。结论:穴位伏安特性随月经的进程而变化,这种变化具有穴位特异性。穴位电阻随月经进程而变大,这可能与月经后机体血量减少有关。穴位伏安特性有可能作为研究气血变化的定量指标。

Volt-ampere characteristics of Yuan points of three yin channels of hand in women before, during and after menstruation

Objective: To observe the changes of volt-ampere characteristics of Yuan-Primary acupoints in women(before,) during and after menstruation, and to find out the relationships between Qi-blood in human body and volt-ampere characteristics of acupoints,so as to develop a new method for quantitative analysis on changes of Qi-blood.Methods: A high-sensitive detection system of volt-ampere characteristics of acupoint was applied to detecting the volt-ampere characteristics of Taiyuan(LU 9),Daling(PC 7) and Shenmen(HT 7) in healthy women before,during and after menstruation.Results: The resistances on LU 9,PC 7 and HT 7 with some(certain) scan currents were quite different among the women before,during and after menstruation.For such changes,PC 7 was of the most obvious change,LU 9 was of the less and HT 7 was of the least.The total ratio of the scanning spots with significantly increasing changes of resistances on these three acupoints(along) with the menstrual process was 70.6%.Conclusion: The volt-ampere characteristics of acupoints vary with the menstrual process,which is of the acupoint specificity. The resistances on the acupoints increase with the menstrual process,and such results may be due to the blood loss during menstruation.The volt-(ampere) characteristics can be used as a quantitative index to study on the change of Qi and blood.
