Abstract

SOKER, Sevda et al. The Effects of Electromagnetic Fields on the Ultrastructure of Heart. Int. J. Morphol. [online]. 2011, vol.29, n.3, pp.960-964. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022011000300050.

Increasingly the use and convenience of electrical appliances in our daily lives are the cause of harmful effects caused by electromagnetic fields (EMF). The aim of this study was to research the effect of EMF on the ultrastructure of the heart in EMF exposed rats. In this study 45 male Sprague Dawley rats ranging in weight between 260 and 280 grams were used. The rats were divided into 3 groups, control (n:15), Sham (n:15) and EMF group (n: 15) and exposed for 14 days 3 hours per day; gauss levels at 2.5 were applied to the EMF group, while the sham group in the same environment in Plexiglas cage was kept for 14 days 3 hours per day without magnetic field exposure. Control group at 14/10 hours light dark cycle fed in normal cages for 14 days. After two weeks rats were sacrificed by 50mg/kg of Ketalar anesthesia and heart tissue fixed in 2.5 gluteraldehide. Routine follow up with electron microscopic assessment. Mitochondrial structures and cellular structures observed in all the groups were normal. Myofibrillar loss, dilatation of smooth endoplasmic reticulum, mitochondrial swelling or cristalysis was not observed. Intercalated disc degeneration and apoptosis of nucleus was not observed. Therefore, and as a result of our study we did not observe differences between control and EMF groups.
