Elektromanyetik alanın köpek arterlerinde oluşturduğu intimal değişiklikler

Objective: İn developedpopulations the İncreasing trend of electromagnetic pollution survives in an insidious and dangerous dimension. Although estlmating the negative effects of electromagnetic field on human organism is very difficult, assessment of their effect on arteries was aimed in this experimental study. Material and Methods: An electrical shaver was choosen as a source of electromagnetic field vvhich was estimated as having a 5-10 gauss electromagnetic field. The shaver was directly periormed on sklns of left common carotid and bilateral femoral arteries of 7 street dogs, vveighing meaniy 20-25 kg, within a mean period of 5 months. This was performed on one time in every week with a period of 7 minutes. Totally, 18 periods were periormed. At the end of the study carotid and femoral arteries were excised for histopathological examination. Results: Tissue examples of 21 study and 14 control specimens were examined under light microscope. İn study group 8 examples had moderate and 7 examples had severe intimal changes, whiie in control group 3 exampies had miid intimal changes. A chi square test betvveen these groups were considered significant (p<0,05). Conclusion: Endothelial injury and subendothe-llal seperations were significantly found in a very short period. These changes may cause stroke due to athero¬genesis on carotid arteries İn a longer period.
