N2 - Background: The modern life condition has resulted in the continuous human exposure to electromagnetic fields. Epidemiologic and animal laboratory studies have illustrated the bad effects of electromagnetic fields on biologic systems. The aim of our study was to see the effect of (EMF) on histopathological of heart-epithelial tissue in rat.
Methods: 30 Vistar rats with weighting 100-150gr and 5 weeks old were used in this study. Test group rats were exposed to the electromagnetic field 8 hours a day for 2 months, and with the intensity of 1 mt; though for the control group no operation was done. After 2 months the rats were anesthetized by used cotton, smeared with chloroform then the heart tissue was sampled. Results: In microscopic observations there were sever disruptions on tissue so that the nucleus of muscular cells was changed polymorphically. Also cytoplasm was unclear and destroyed fibrous tissue and cells involved in necrosis in the form of coagulated necrosis and bleeding. But in control group the whole tissue and its cells were normal.
Conclusion: The results of the current study showed that considering histopathogenic examination such as coagulated necrosis, etc. the electromagnetic waves brought about the apparent changes in heart tissue (p<0.05).
