چکیده
Introduction: Daily application of various devices like microwave, mobile phone, medical devices and etc. would put people in the risk of electromagnetic radiation exposure. As a non-thermal effects of electromagnetic waves on human cells, exposure to mobile radiation cause in generation of reactive oxygen species, which is resulted in oxidative stress. The most used frequency in GSM, global system for mobile communication, in Asia, is 900 MHz. This study has investigated the effects of mobile phone (915 MHz) – induced electromagnetic radiation on DNA damage and TAC in blood of pregnant mice and the preventive role of vitamin C as an antioxidant.Materials and Methods: 21 pregnant mice were divided into 3 groups (control, exposure and exposure plus vitamin). The exposure groups were exposed to mobile phone radiation (915 MHz and 0.045 μw/cm2 power density, 8 h/d for 10 days) during pregnancy. The exposure plus vitamin group was received vitamin C (200 mg\Kg) by gavage. After 5 days, the mice were anesthetized and their blood samples were collected from the heart. 8-OHdG and TAC were measured by analytical commercial kits. All data were analyzed by ANOVA-Tukey test using SPSS (24.)Results: Significant increase in 8-OHdG levels were observed in exposure group (42.439± 1.3 ng/ml) compare to control (36.29±1.92 ng/ml) and exposure plus vitamin C groups (31.051±1.046 ng/ml). The TAC levels in exposure group (0.054±0.003mM) and exposure plus vitamin C group (0.068±0.001mM) had a significant decrease compare to the control group (0.082±0.004mM) (p = 0.001).Conclusion: Electromagnetic radiation caused DNA damage in blood of pregnant mice RFR caused oxidative stress in pregnant mice and increased DNA damage biomarker level and changes in TAC level. Consumption of vitamin C could prevent these changes in some extent. Studies on non-ionizing radiation during pregnancy will help define threshold limit for its exposure for pregnant women and protect them.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
