Trace elements homeostasis in brain exposed to 900  MHz RFW emitted from a BTS‐antenna model and the protective role of vitamin E

AbstractAdvances in telecommunication and their broad usage in the community have become a great concern from the health aspect. The object of the present study was to examine the effects of exposure to 900  MHz RFW on brain Iron (Fe), Copper (Cu), Zinc (Zn) and Manganese (Mn) concentration, and the protective role of pre‐treatment of vitamin E on mentioned elements homoeostasis. Twenty adult male Sprague–Dawley rats (200 ± 20 g) randomly were divided into four groups. Control group (without a ny exposure, received distilled water), treatment control group (orally received 250 mg/kg BW/d vitamin E), treatment group (received 250 mg/kg BW/d vitamin E and exposed to 900 MHz RFW) and sham‐exposed group (exposed to 900 MHz RFW). Animals (with freely moving in the cage) were exposed to R FW for 30 consecutive days (4 hr/day). The levels of the above mentioned elements in the brain tissue were determined on the last day using atomic absorption spectrophotometry. Exposure to 900 MHz RFW induced a significant increase in the Fe, Cu, Mn levels and Cu/Zn ratio accompanied by a signific ant decrease in Zn level in the sham‐exposed group compare to control group. Vitamin E pre‐treatment improved the level of Fe, Cu, Mn and Cu/Zn ratio, except in the Zn concentration. Exposure to 900 MHz RFW caused disrupted trace elements homoeostasis in the brain tissue and administration of v itamin E as an antioxidant and neuroprotective agent improved the situation.
