Electromagnetic Field Effects on the Morphometrical Characteristics of Rat Adrenal Glands

Abstract

Effect of the magnetic field on the biological mechanisms is still poorly known. It was considered for a long time that the effect of magnetic field was identical to the effects produced by high and low temperatures, ultraviolet rays and noise (Nakagawa, 1984). Long-term exposure to LF-EMF induced morphological and morphometrical changes on thyroid gland (Matavulj et al, 1996) and adrenal glands (Uscebrka et al, 1996). Magnetic fields have been shown to influence the release and levels of a number of neurotransmitters (Kavaliers and Ossenkopp, 1987; Zecca et al, 1997) and opioid molecules (Prato and Kavaliers, 1997), with these actions being proposed to involve alterations in neuronal calcium levels and fluxes (and possibly other divalent ions) and in the stability of calcium binding to neuronal membranes (Blackman et al., 1985, Kavaliers and Ossenkopp, 1986).
