The histopathological changes in the rats caused by magnetic field of 50 Hz. freguency.

Background: Electromagnetlc fields (EME) are the most important environment problems that effect the public health in our century. Increasing incidence of coronary heart disease, leukemia, lymphoma, and Alzheimer in the patients who are effected from magnetic fields, are revealing that these sources can not be used unlimitedly. İn this study, we would like to investigate the effect of hairdryer on the rats. Materials and methods: İn this study, 200-250 gr weighted 29 male rats vvere used. 15 of them were control group, and 14 vvere faced with EMF. A BKK 1161 SK hairdryer was used as the magnetic field source. This machine had 600 VVatt (W) power, 220 V - 50 Hz resistance, and a mean magnetic field counted 100-150 mG. The distance betvveen the subjects and the machine was 20-25 cm. EMF was performed on them for 3 days of each week, and 5 minutes of each day, and it was lasted after 3 months with a total period of 205 minutes. At the end the malondialdehid (MDA) levels in the subjects sera vvere calculated, and they vvere sacrificed and their cerebrum, thymus, lungs, heart and great vessels, liver, kidneys, and spleen vvere taken to histopathologic examination under light microscope. Results: İt was obviously observed that the EMF in 50 Hz freguency increases the mononuclear celi infiltration in the viscera; especially, it was estimated that EMF causes alveolar destruction in the lungs, tubuler degeneration in the kidneys, glial proliferation in the cerebrum, fibrosis in the liver, and adventitial mononuclear celi infiltration in the great vessels in 3 months, vvhich is thought to be a very short period. Statistically, the subendothelial dissection in the great vessels was not found significant, hovvever, this was thought to be an important finding. The serum MDA levels of EMF group vvas increased, but statistically, this was not significant. Conclusion: We concluded that EMF causes an increase in the production of free oxygene radicals, and in the late-term this results with various diseases including cancers and atherosclerotic dişe ases.
