Abstract

The effect of low-intensity extremely high-frequency electromagnetic radiation (EHF EMR, 42.0 GHz, 0.1 mW/cm2, 20 min daily) on cell-mediated immunity and nonspecific inflammatory response in mice was studied. The intensity of cell-mediated immune response in the reaction of delayed-type hypersensitivity and nonspecific inflammation was estimated by a relative increase in the thickness of foot pad after immunization of animals by sheep red blood cells or zymosan. It was shown for the first time that the radiation reduces both immune and nonspecific inflammatory responses. It was shown with the use of models of acute inflammation and full-thickness skin wounds that EHF EMR suppresses the nonspecific inflammatory response but does not influence the duration of the pathological process. We suppose that the basis of the effects revealed is the modification of functional activity of phagocytic cells under the influence of EHF EMR. The results suggest that some therapeutic effects of EHF EMR can be realized via the inhibition of inflammatory processes.
