Abstract: (858 Views)
Purpose: Increasing use of electromagnetic waves in living medium, industry, communication and medicine, strongly requires multiporposal evaluation of the effects of electromagnetic fields (EMF), with different frequencies, on body tissues and organs.Contrauersal reports on detrimental effects of EMF on biological systems influenced us to carry out this study.
Materials and Methods: In order to evaluate the effects of uniform EMF on biologic systems, we devised a calibrated EMF unit (50-60Hz, adjustable in 15 range which could produce upto 150 G EMF). Six pairs of pregnant rats were exposed to 120 G uniform electromagnetic field (50-60Hz), for determining the effects of EMF on development of emberyonic cerebral. They were daily exposed to EMF during pregnancy and 2 month after birth for 8 hours. Then prepared histologic specimens of rats cevebral were studied by light microscop.
Results: Histological studies showed that in experimental group in comparison with control group the size of cells and their nuclei were decreased, while matter in cerebrum were vacualized and Ependymal cell increased.
Conclusion: The above data offers that the effect of EMF on man should be taken into consideration.
