[Effect of weak alternating magnetic fields on infradian rhythms of rat blood leukocyte functional activity]

It was demonstrated that variable magnetic field with 8 Hz frequency and 5 microT induction in daily 3 hours exposure during 40 days changes infradian rhythmicity of functional state parameters of lymphocytes (succinic- and glycerophosphate dehydrogenases activity) and neutrophiles (peroxidase activity) in the blood of the rats. These changes consist in integral rhythms reconstructions, amplitude and phase shifts.
