“…As RF-EMF exposure can affect body temperature, we measured rectal temperature before and after RFID exposure; no statistically significant changes in temperature were found in our exposure system (data not shown) [Kim et al, 2013a,b]. Hence, we suggest that the differences between our study and previous research with respect to the positive effects on immunity [Cleary et al, 1996;Stankiewicz et al, 2006;Erken et al, 2012;Khamidova, 2014] were caused by EMF exposure conditions and thermal effects.…”

“…In contrast, several studies have suggested statistically significant changes in peripheral blood following exposure to RF-EMF [Cleary et al, 1996;Stankiewicz et al, 2006;Erken et al, 2012;Khamidova, 2014]. A rat study reported decreased tissue oxygenation in rats, which was caused by a reduction in RBC deformability after exposure to RF-EMF generated by 1,800 MHz cell phones for 2.5 h/day and 2.5 min/day for 30 days [Erken et al, 2012].…”

We investigated whether exposure to the 915 MHz radiofrequency identification (RFID) signal affected circulating blood cells in rats. Sprague-Dawley rats were exposed to RFID at a wholebody specific absorption rate of 2 W/kg for 8 h per day, 5 days per week, for 2 weeks. Complete blood counts were performed after RFID exposure, and the CD4 þ /CD8 þ ratio was determined by flow cytometry. The number of red blood cells (RBCs) and the values of hemoglobin, hematocrit, and RBC indices were increased in the RFID-exposed group compared with those in the cagecontrol and sham-exposed groups (P < 0.05). However, the RBCs and platelet numbers were within normal physiologic response ranges. The number of white blood cells, including lymphocytes, was decreased in RFID-exposed rats. However, there was no statistically significant difference between the sham-exposed and RFID-exposed groups in terms of T-cell counts or CD4 þ /CD8 þ ratio (P > 0.05). Although the number of circulating blood cells was significantly altered by RFID exposure at a whole-body specific absorption rate of 2 W/kg for 2 weeks, these changes do not necessarily indicate that RFID exposure is harmful, as they were within the normal physiological response range.

“…Similar results to our findings were reported following exposure to EMF (950 MHz for 8 weeks) (Gharib, 2014). Moreover, exposure to mobile phone radiation (1,800 MHz) was reported to reduce the erythrocyte zinc level (Erken et al, 2012). Another study has reported that exposure to Wi-Fi and mobile phone radiation caused oxidative damage by increasing the extent of lipid peroxidation and the iron level while decreasing total antioxidant status, copper, and GSH values in kidney and testis (Ozorak et al, 2013 Note: Different alphabets in each row, indicate a significant difference with other groups (p < .05).…”

Advances 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 any 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 RFW 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 significant 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 vitamin E as an antioxidant and neuroprotective agent improved the situation.

Background: There is an increasing public concern about the harmful effect of exposure to electromagnetic radiation emitted from base transceiver stations (BTS). Objectives: This study was carried out to evaluate the impact of exposure to 900 MHz radiofrequency (RF) on the concentration of brain trace elements (TEs), including zinc (Zn), manganese (Mn), copper (Cu), and iron (Fe), as well as the protective effect of vitamins (C and E) supplementation. Methods: In this study, 30 male rats were assigned into three non-exposed groups, including sham I, II, and III receiving saline, vitamin C, and vitamins C+E, respectively, and three exposed groups, including sham-exposed (saline), test I (vitamin C), and test II (vitamins C+E). The exposed groups were exposed to RF for one month (4 h/day) and the brain TE levels were measured using atomic absorption spectrophotometry. Results: Compared with the non-exposed groups (I, II, and III), a remarkable elevation in the concentration of Mn, Fe, Cu, and Cu/Zn ratio accompanied by a significantly lower level of Zn was noticed in the rats’ brain of the sham-exposed group (P<0.05). However, pretreatment with both vitamins C and C+E improved the evaluated TE imbalances caused by exposure to 900 MHz RF with no significant difference between the two test groups (P>0.05). Conclusion: Disruption of brain TEs homeostasis caused by the exposure to 900 MHz RF improved and normalized by pretreatment with vitamins C and E+C.
