Electromagnetic Field Effect on Skeletal Muscles and Skin of Albino Rat Embryos Histological and Histochemical Studies

摘要

Aim of the work :The present study aimed to investigate the possible effect of the electromagnetic field (EMF) on the skeletal muscles and skin of fetuses maternally exposed to EMF. Material and Methods: Pregnant Swiss albino rats were exposed to EMF(50Hz&2mT) 8hours day after day 10 days before pregnancy and 20 days, day after day through pregnancy. Results: Exposure of pregnant rats to the electromagnetic field (EMF)of 50 Hz and 2millitesla(2mT), showed many dystrophic changes in the skeletal muscles and skin of their fetuses .Highly thickened and disturbed epidermal layer was noted with decreased number of hair follicles. Some hemorrhagic areas were noted in the dermis. Highly disturbed skeletal muscle fibers were noted with many deleterious changes in the nuclei of their cells. Altered protein content, polysaccharides and collagen bundles were observed in the muscle fibers and skin of fetuses taken from exposed pregnant rats to EMF. Conclusion : It is clear that EMF has a deleterious effect on skin and skeletal muscles of fetuses maternally exposed to EMF.
