Effects of Pulsed Electromagnetic Fields on the Proliferation of Lymphocytes from Aids Patients, HIV-Seropositive Subjects, and Seronegative Drug Users

Abstract

The effect of the exposure of mitogen-stimulated lymphocytes from subjects infected by human immunodeficiency virus to extremely low frequency pulsed electromagnetic fields (PEMFs) was studied, by evaluating the incorporation of tritiated thymidine, the expression of IL-2 receptor, and the amount of activated T lymphocytes. Four groups of subjects were considered patients with acquired immunodeficiency syndrome (AIDS), asymptomatic seropositive subjects, seronegative drug users, and young healthy controls. PEMFs increased cell proliferation only in the group of healthy controls, as measured at the 72nd hour of culture, but an increase in the number of activated T lymphocytes was observed by cytofluorimetric analysis after 18 hrs of PEMF exposure in cultures from AIDS patients.
