Tribrat N. Modulation of microcirculation processes with the help of low millimeter radiation

Using the method of laser Doppler flowmetry it was shown that low-intensity EHF EMR has a gross effect on the processes of microcirculation in human skin, wich expressed in a change of nonoscillatory and oscillatory characteristics of basal blood flow and indices of microvascular tone. Momentary influence of EHF EMR leads to a local decrease in peripheral resistance and domination of nutritional blood flow in the shunt one against depression in favor of which indicate an increase in the amplitudes of myogenic and endothelial tissue blood flow oscillations indicate the against background of a decrease myogenic tone and indicator shunt only in the localization of EHF exposure. Repeated exposure EHF EMR has a shiking effect on the change of nonoscillatory and oscillatory indicators of passive and active regulation factors of microcirculatory processes resulting in an increase in the production of vasodilators, decrease in peripheral resistance in the arterioles and precapillares, increase blood flow in the microvascular against the background improved venular outflow. In the mechanisms of action of low-intensity EHF EMR on microcirculatory processes the main role belongs to endothelium-dependent, endothelium-independent myogenic and neurogenic components of the regulation of tissue blood flow.
