Objective:To observe the volt-ampere characteristics of the acupoints by devascularization.And then we can study the relationship among functional specificity of acupoints,qi and blood in human body and volt-ampere characteristics.Methods:23 healthy volunteers are randomly divided into two groups of left forearm blood line blocking and right forearm blood line blocking.Their brachial arteries are pressed by the cuff of a sphygmomanometer,which causing forearm devascularization.Detect the volt-ampere curves ...
