[Changes in the infradian rhythm of the dehydrogenases in the blood lymphocytes of rats due to epiphysectomy and the action of weak alternating magnetic fields].

In experiments with 110 white inbred male rats, the infradian rhythm changes in succinate- and alpha-glycerophosphate dehydrogenases in rat's lymphocytes due to epiphysectomy, exposure to transitory magnetic field (TrMF) at 8 Hz and 5 microTl, and their combined effect were studied. According to spectral analysis, the infradian rhythms of lymphocyte succinate dehydrogenase, alpha-glycerophosphate dehydrogenase mean activities in intact animals amounted to 26.5 +/- 2.5; 19.1 +/- 1.1; 13.5 +/- 1.1; 9.1 +/- 0.8; 6.9 +/- 0.7; 3.6 +/- 0.2 days. Epiphysectomy decreases the observed rhythm amplitudes, shifts phases, disrupts temporal organization of the redox processes, i.e., induces desynchronosis. TrPM at 8 Hz also causes desyncronosis in intact animals though less pronounced than in epiphysectomized rats. TrMP partially normalizes temporal organization of the dehydrogenase status in epiphysectomized rats. Our findings point to the possibility to apply TrMF for "functional epiphysectomy" of intact animals and, in case of desynchronoses, as biorhythm "time sensors".
