influence of 50 Hz magnetic field on liver oxidative

ABSTRACT

The influence of static magnetic fields [SMFs] or modulated magnetic fields [MMFs] on biological systems has been a topic of considerable interest for many years. At the current state of knowledge, the biological effects, both in vivo and in vitro, of SMFs have yet to be unequivocally interpreted. Induced electric currents, unlike time-varying electromagnetic fields, are not associated with these fields except during activation and deactivation or when there is movement within the field. The study involved the effect of magnetic field on the oxidative state of the liver tissue. The study was conducted on Sparague-Dawely male rats of an average weight of 140-160 gm. The exposure period was 7 days [2 hours/day]. The applied field also caused an increase in the lipid peroxide [H2O2] and a decrease [p<0.05] in its glutathione [GSH] concentration. Results, as the spectroscopic examination of the serum illustrates, suggest that the redox [reduction/oxidation reaction] potential of NADH/NAD is disturbed as a result of exposure to magnetic field resulting in an exhaustion of NADH. Consequently, precursors of NADH, such as kynurenine, tyrosine and tryptophan, are supplied by the body
