Acupuncture points require detailed study because they are the main and well known component of the meridian system of the traditional Chinese medicine that participate in the acupuncture treatment mechanisms, the therapeutic effect of which is unclear today.

The aim of the investigation was the study of both: electrical conductivity and temperature (contact and radiant) of the skin in acupuncture points. They are P9, MC7, C7, iG5, TR4, Gi5, RP3, F3, R3, V64, VB40 and E42 points, which also named representative acupoints of the meridians (by Nakatani).

Results of the study show that parameters of the skin electrical conductivity in acupuncture points were characterized by high variability. They could be above or below temperature of nearby skin sites and correlate with functional activity of correspondent organs and systems. Changes of the skin electric conductivity of acupuncture points in reply to their irritation specifies in high reactance of point tissues. Stimulation of acupuncture points by superhigh-frequency electromagnetic field (54-75 GHz), chosen according to canons of east medicine, was accompanied by increase initially low and decrease in initially overestimated parameters of the skin electric conductivity in representative points to average physiological level. Some findings confirming existence of the meridian system and functional ties between the meridians were noted. The contact skin temperature in acupuncture points was differ in comparison with beside acupoint one. The radiant skin temperature as a rule was above contact temperature and could change quickly on 2-3 degrees during the short time interval. Certain interdependence between skin electrical conductivity and temperature parameters was noted.

The hypothesis of acupuncture mechanisms was offered. It assumes that meridians and acupoints are important components of the whole regulatory system that phylogenetically take priority of the nervous and endocrine systems and can induce the genetically fixed adaptive and compensatory mechanisms for realization its therapeutic effect by specific bioactive substances.

Results of the present study show that skin electric conductivity and skin temperature in area of acupuncture point differed variability, and their parameters are caused by a functional condition of organs and systems. Level and dynamics of the changes of radiant temperature in acupuncture points assume presence in them of the generators of infra-red radiation.
