Changes in effector function of sensory peptidergic pervascular fibers after multiple exposures to low-intensity millimeter radiation

Abstract

The effector function of sensory peptidergic perivascular fibers was examined upon multiple exposures to low-intensity millimeter electromagnetic waves by means of laser Doppler flowmetry. Low-intensity millimeter waves (wavelength, 7.1 mm; power density, 0.1 mW/cm2) were shown to increase the microcirculation index, which characterized the change in perfusion upon electrical stimulation, and to decrease the latency from the start of stimulation to the onset of vasodilation, pointing to an increase in the effector function of sensory peptidergic fibers and micruvascular reactivity.
