月经前后足部原穴反射光谱特性比较

观察了足部三个原穴在月经前后人体气血盈亏变化过程中的反射光谱特征及其差异性,探讨了穴位在反映人体气血方面的特异性。采用线阵CCD探测器的光纤光谱仪获取太冲(LV3)、太白(SP3)、冲阳(ST42)三个穴位在月经前后400~700 nm范围内的反射光谱,并对特定波长处的反射率进行统计学分析。结果表明,不同个体、不同时期的同名穴位反射率有差异,但光谱轮廓相似,波谷均出现在423.16,544.06和577.47 nm处。太白月经中较月经前、后变化明显高于太冲、冲阳(P0.05),太白、冲阳月经中的反射率高于月经前和月经后,具有统计学意义。月经前后穴位反射特性变化与机体气血由盛而衰变化规律有关。

Comparative study of reflectance spectroscopy of women's acupoints around menstruation

Acupoint was reaction of viscera and its optical parameter was an important characteristic of tissue. In the present work, in order to discuss specificity of acupuncture on the response of qi and blood in human body, we compared the diffuse reflectance of Taichong (LV3), Taibai (SP3), and Chongyang (ST42) before, during and after menstruation. All the acupoints had the same shape of the spectrum and troughs were all at 423.16, 544.06 and 577.47 nm. The values of reflectance during menstruation were greater than before and after menstruation, especially for SP3 and ST42 (P < 0.05). SP3 and ST42 were more sensitive to the changes of qi and blood than LV3, and it was asymmetric and we found no evidence for the imbalance of the left side and right. These results indicated that acupoint diffuse reflectance changed with qi and blood, and that SP3 and ST42 had close relationship with menstruation. Diffuse reflectance may be possibly used in the quantitative analysis of qi and blood.
