Microwaves Induce an Increase in the Frequency of Complement Receptor-Bearing Lymphoid Spleen Cells in Mice

Abstract

A single 30-min exposure of mice to 2450 MHz microwaves (12 to 15 mW/g body weight) in an environmentally controlled waveguide facility induced a significant increase in the proportion of complement-receptor positive lymphoid cells in the spleen. This effect was further enhanced by repeated (three times) exposures, which in addition produced a significant increase in the proportion of Ig⁺ cells. The proportion of θ-positive cells and the total number of spleen cells remained unchanged.
