چکیده    Despite more than a decade of research on the endocrine system,there have been no published studies about the effects of concurrent exposure of radiofrequency electromagnetic fields (rf-emf) on this system. the present study investigated the several parameters of the endocrine system including melatonin,thyroid stimulating hormone,stress hormone and sex hormone after code division multiple access (cdma,849 mhz) and wideband code division multiple access (wcdma,1.95 ghz) signals for simultaneous exposure in rats. sprague-dawley rats were exposed to rf-emf signals for 45 min/day,5 days/week for up to 8 weeks. the whole-body average specific absorption rate (sar) of cdma or wcdma was 2.0 w/kg (total 4.0 w/kg). at 4 and 8 weeks after the experiment began,each experimental group's 40 rats (male 20,female 20) were autopsied. exposure for 8 weeks to simultaneous cdma and wcdma rf did not affect serum levels in rats of melatonin,thyroid stimulating hormone (tsh),triiodothyronine (t3) and thyroxin (t4),adrenocorticotropic hormone (acth) and sex hormones (testosterone and estrogen) as assessed by the elisa method. © 2012 the author 2012.
