The radiofrequency electromagnetic radiation emitted by smart phones on biological systems has wide media coverage and public concern in recent years. The aim of this study was to explore the effects of fourth-generation cell phone radiation exposure on hematological (Total leukocyte count, Total erythrocyte count, and hemoglobin %), biochemical (Serum creatinine) parameters, and histopathological changes in the kidney and testis of Swiss albino mice. A total of 30 male Swiss albino mice weighing 45-65 g was randomly divided into three groups ( = 10). The first group A was the control group, the second group B, was exposed to 40 minutes of mobile phone radiation daily, the third group C was exposed to 60 minutes of radiation daily from two 2400 Megahertz fourth-generation connected mobile phones for 60 days, respectively. The electromagnetic radiation frequency radiometer measured the frequency of electromagnetic radiation emitted from cell phones. The specific absorption rate was calculated as 0.087 W/kg. The control group was kept under similar conditions, but the electromagnetic field was not given for the same period. All the mice were sacrificed at the end of the experiment. The blood samples were collected for hematobiochemical study, and then kidney and testis tissues were collected for histopathological study. Results of the study showed that the body weight and total erythrocyte count values were significantly (p < 0.05) decreased while total leukocyte count, hemoglobin %, and serum creatinine values were significantly (p < 0.05) increased in both the radiation exposure groups relative to the control group. Histopathological observation showed the kidney of 60 minutes exposed mice interstitial inflammation that causes marked mononuclear cellular infiltration compared to the 40 minutes and control mice. Compared to control mice, histopathological examinations of testicular tissue from the exposed mice, showed irregular in shapes and non-uniform sizes and fewer spermatogenic cells layer that leads to the larger lumen in the seminiferous tubules. It is concluded that fourth-generation cell phone radiation exposure may affect blood hemostasis and inflammation of mice's kidney and testis tissue. Based on these studies, it is important to increase public consciousness of potential adverse effects of mobile phone radiofrequency electromagnetic radiation exposure.
近年来,智能手机发出的射频电磁辐射对生物系统的影响受到了广泛的媒体关注和公众关切。本研究的目的是探讨第四代手机辐射暴露对瑞士白化小鼠血液学参数(白细胞总数、红细胞总数和血红蛋白百分比)、生化参数(血清肌酐)以及肾脏和睾丸组织病理学变化的影响。总共30只体重为45 - 65克的雄性瑞士白化小鼠被随机分为三组(每组n = 10)。第一组A为对照组,第二组B每天暴露于40分钟手机辐射,第三组C每天分别由两部2400兆赫兹的第四代联网手机辐射60分钟,共60天。电磁辐射频率辐射计测量手机发出的电磁辐射频率。比吸收率计算为0.087瓦/千克。对照组保持在类似条件下,但同期不给予电磁场。实验结束时处死所有小鼠。采集血样进行血液生化研究,然后采集肾脏和睾丸组织进行组织病理学研究。研究结果表明,与对照组相比,两个辐射暴露组的体重和红细胞总数显著降低(p < 0.05),而白细胞总数、血红蛋白百分比和血清肌酐值显著升高(p < 0.05)。组织病理学观察显示,与40分钟暴露组和对照组小鼠相比,60分钟暴露组小鼠的肾脏出现间质炎症,伴有明显的单核细胞浸润。与对照小鼠相比,暴露组小鼠睾丸组织的组织病理学检查显示,其形状不规则、大小不均匀,生精细胞层较少,导致曲细精管管腔较大。结论是,第四代手机辐射暴露可能影响小鼠的血液止血以及肾脏和睾丸组织的炎症。基于这些研究,提高公众对手机射频电磁辐射暴露潜在不良影响的认识非常重要。
