    ELF electromagnetic field and strontium ranilate influences on the trace element content of rat teeth
    (2009) Kaya S.; Akdag M.Z.; Yavuz I.; Celik M.S.; Adiguzel Ö.; Tumen E.C.; Kaya F.A.
    Exposure to Extremely Low Frequency (ELF) Electromagnetic Field (EMF) emanating from the generation, distribution and utilization of electricity. The major debate in recent years has focused on the possibility that exposure to EMF may result some health consequences such as differentiation on bone constitute. In this study, the effect of ELF-EMFs and strontium ranelate on teeth constitute amount of mineral were investigated in rats. Seventy-five four month old adult female Sprague-Dawley rats were randomly divided into 5 different groups (n = 15). After all applications, some mineral levels such as: Ca, Mg and Zn in rat teeths were determined with Atomic Absorbtion Spectrophotometry (AAS) and the phosphorus content of teeth was determined by Ultraviolet Spectrophotometer (UVS). It was determined that the levels of Ca and P were not statistically different in comparison to Cg-Cnt and between groups (p>0.05). However, it was observed that the levels of Zn significantly alterations between some groups (p<0.05). The levels of Mg in ELF-EMF+OVX, ELF-EMF and OVX groups decreased significantly in comparison to Cg-Cnt group (p<0.05). As a resulf it can be suggested that mineral amount of rat teeth can change after ovariectomy and ELF-EMF exposure, also strontium ranelate treatments can't increase mineral amount of teeth. © Medwell Journals, 2009.

    Hormone levels of people occupationally exposed to radiofrequencies
    (1999) Dasdag S.; Balci K.; Kaya H.; Celik M.S.
    The present article intended to investigate some hormone levels of technicians in the radio-broadcasting, television (TV) and radio - link stations. The study was carried out on 43 technicians from 20 to 59 years age occupationally exposed to radiofrequency (RF) and microwave (MW) radiation. 20 unexposed and voluntary persons from 20 to 59 years age were accepted as a control group. We determined the levels of some hormones as triiodothyronine (T3), tetraiodothyronine (T4), thyroid stimulant hormone (TSH), free T4, estradiol, dehydroepiondrosterone sulfate (DHEA), testosterone, cortisol and progesterone in the technicians under investigation. The hormone levels of exposure groups were statistically compared with the unexposed control group. T3, T4, estradiol, testosterone and progesterone levels of technicians in the radio-link and TV transmitter stations were found to be significant (p < 0.05, p < 0.001). T3, T4, TSH, estradiol and progesterone levels of technicians in the broadcasting station were also found to be significant (p < 0.001). In conclusion some hormone levels of technicians under investigation were altered by RF/MW.
