Abstract
Aim: Long-term exposure of humans to low intensity radiofrequency electromagnetic radiation (RF-EMR) leads to a statistically significant increase in tumor incidence. Mechanisms of such effects are unclear, but features of oxidative stress in living cells under RF-EMR exposure were previously reported. In this study, we aimed at elucidating the effects of microwave radiation emitted by a commercial model of GSM 900 MHz cell phone on embryo developments in quails (Coturnix coturnix japonica) during prolonged exposure. Materials and methods: Embryos of Japanese quails were exposed in ovo to extremely low intensity RF-EMR of GSM 900 MHz (0.21 µW/cm2) for 158-456 h discontinuously (48 s - ON, 12 s - OFF) before and in the initial stages of development. The total survival of embryos, levels of thiobarbituric acid reactive substances (TBARS), catalase activity and concentration of paramagnetic centers were assessed in cells/tissues RF-EMR of exposed and unexposed embryos or daily quail. Results: The irradiation led to decrease in total survival of embryos from exposed eggs after 19 days exposure. A level of TBARS was significantly (p<0.01–0.001) higher in tissues of hatching from exposed embryos. As a result increased levels of TBARS followed by significantly (p<0.05–0.01) decreased levels of catalase activities were developed in the exposed embryo cells. In addition to this, irradiation led to decrease of concentration of paramagnetic centers in hearts and lіvers of daily quail. Conclusion: Observed effects of radiation from commercial GSM 900 MHz cell phone on developing quail embryos signify a possibility for non-thermal impact of RF-EMR on embryogenesis.
