50-HZ, 1-MT SINUSOIDAL MAGNETIC-FIELDS DO NOT AFFECT MICRONUCLEUS FREQUENCY AND CELL-PROLIFERATION IN HUMAN-LYMPHOCYTES FROM NORMAL AND TURNERS-SYNDROME SUBJECTS

In the present study, we investigated the effect of a 50-Hz sinusoidal magnetic field at 1 mT rms field intensity on cell proliferation and micronucleus frequency in peripheral blood lymphocytes exposed for 72 h. Lymphocyte cultures from 5 subjects affected by Turner's syndrome w ere tested; cultures from 5 healthy donors were also studied to make a comparison with a control group. No statistically significant differe nces in micronucleus frequency and cell proliferation were found betwe en control and exposed cultures from healthy and TS donors. The result s obtained indicate that the field tested does not exert any genotoxic effect nor interfere with cell cycle.
