Abstract
The purpose of this work was to initiate a study of extremely low-frequency magnetic field effects on peripheral blood in mice. Female OF1 outbred mice resistant to spontaneous tumors were introduced into an experimental magnetic field of a 0.1 mT 50 Hz sinusoidal wave generated by a source in a solenoid, for 3 months. As a consequence of physical agents, a significant leukopenia and significant qualitative alterations of white blood cells (blast cells and young lymphocytes increased) were detected in all exposed specimens. This pathology is identified as lymphocytic aleukemic leukemia.
