Insanligin hizmetinde kullanilan bu cihazlarin faydalarinin yaninda zararli etkileri de ortaya cikmis ve noroendokrin sistem uzerine bir takim yan etkilerinin olabilecegi dusunulmustur. Bu calismada, 900 MHz dalga frekansinda elektromanyetik alanin (EMA) ratlarda, kortizol ve testosteron hormonlari uzerine etkisinin olup olmadigini arastirdik. Calismamizda, 20 adet Spraque Dowley turu erkek rat kullanildi. Ratlar, kontrol (K) ve EMA olmak uzere iki gruba ayrildi. EMA grubundaki ratlar, 4 hafta boyunca haftada 5 gun ve gunde 30 dakika 1±04 mW/cm2 gucunde 900 MHz dalga frekansinda EMA' a maruz birakildi. K grubu da ayni deney ortaminda tutuldu, fakat EMA uygulanmadi. Ratlarin serumlarinda, kortizol ve testosteron seviyeleri incelendi. Calismamizda elde ettigimiz bulgulara gore; EMA grubunun kortizol seviyelerinin kontrol grubuna gore anlamli olarak yuksek oldugu gorulurken, EMA grubunun testosteron seviyesi ise kontrol grubuna gore anlamli olarak dusuk bulundu. Sonuc olarak cep telefonlarinin yaydigi EMA'nin noroendokrin sisteme etkileri termal ve stres kaynakli olabilir. Ancak, bu konudaki fizyolojik ve morfolojik calismalarin daha ileri duzeylerde yapilmasi gerekmektedir. Anahtar kelimeler: 900 MHz, elektromanyetik alan, kortizol, testosteron. Abstract Effect of 900 MHz electromagnetic field emitted from cellular phone on serum cortisol and testosterone levels Using cellular phones increases day by day with the inspired thought of the articles that reports the harmful effects of cellular phones on human health. This is a growing health problem for human being. These vehicles are in the service of mankind and they are useful for man but at the same time they have harmful effects too and it is believed that they may have side effects on neuroendocrine system. In the present study, our aim was to investigate the effects of pulsed 900 MHz electromagnetic field (EMF) on cortisol and testosterone levels of the rat organism. In this study, we have used 20 Spraque Dowley male rats. The rats were separated into two groups as control (C) and EMF group. EMF group was exposed to the carrier frequency of 900 MHz with average power flux density 1±04 mW/cm2, 30 minutes a day and 5 days a week for 4 weeks. C group was kept at the experiment environment but they didn't exposed to magnetic field. Cortisol and testosterone levels were evaluated in serum rats. The findings we have got in this study are; cortisol values at the EMF group was significantly higher than the C group, however, testosterone values were lower at the EMF group when it is compared with the C group. In conclusion, the effect of the EMF waves that is spread out by the cellular phones on neuroendocrine system may be originated from thermal and stress processes. However, physiological and morphological advanced studies has to be done about this subject. Key words: 900 MHz, electromagnetic field, cortisol, testosterone.
