“…Mobile phone use has dramatically increased over the last decade. Researchers had recommended that electromagnetic fields (EMF) released into the atmosphere from a mobile phone has deleterious effects on human beings ( Azab, 2017 , Elmas, 2016 ). At present mobile phones have started using fourth generation (4G) wireless communication technology (2200–2400 Megahertz (MHz)) that offer a very high Internet speed.…”

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 ( n = 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.

A reading observed that exposure of humanoid and experimental animals to Electric Motive Forces has a negative effect on the heart and blood vessels by make happen a histopathological changes and disturbances in the functions of the organs of the (CS) [14].

Background:The study of Heart rate is very important the body heart is directly related to heart rate ,the autonomic cardiovascular examination provides necessary information about function of the autonomic nervous system as well functional capacities of effectors he art and vessels and other associated part with radiation . Objective: To study the effect of jammer on autonomic nervous system as measured by heart rate. Patients and Methods: Heart rates of 10 males (age 21-51 years), and 10 females (age 20-54 years) were measured and recorded before, during using jammer for 15 minutes, 30 minutes, and 45 minutes, and one hour after shutting down the device . Results: The results clearly indicate that jammer radiation induced high fluctuations in heart rate variability of recovery period (after15 minutes using jammer) and show that the change of heart rate variability signal during jammer exposure is not permanent. There was no statistically significant difference observed in heart rate. Conclusion:The heart rate flection resulting from exposure to radiofrequencies of jammer are depending on the orientation of both electric &magnetic field of the electromagnetic radiation, the greater increase in heart rate that occurred during E orientation irradiation.

“…8 Previous studies showed that an association between elevated EMFs exposure and mortality of employer in electric utility industry jobs from arrhythmia-related causes and acute myocardial infarction influence heart rate variability by changing autonomic balance. 2 Exposure to EMFs induces heart palpitations, pain in the chest area, and an irregular heartbeat. Also, exposure to EMFs causes a decreases in total antioxidant capacity and plasma calcium level.…”

Background: The use of mobile phones, wireless, and electrical devices has gradually increased throughout the last century, and scientists have suggested that electromagnetic fields (EMFs) generated by such devices may have harmful effects on living creatures. Many studies revealed that the EMFs might produce a variety of adverse effects on human health as headaches, chronic fatigue, heart problems, stress, nausea, chest pain, and also some bad effects on central nervous, endocrine and immune systems. Exposure to EMF result in deterioration of RBCs function and metabolic activity, it was expected that, the increase of toxicity in specific organs was a result of the RBCs functional failure. The mechanisms by which the electromagnetic fields cause their bad effects may be by causing deterioration in cellular large molecules, imbalance in ionic equilibrium and generation of reactive oxygen species (ROS). These reactive oxygen species can damage cellular components such as proteins, lipids and DNA. Measurements of blood parameters are of the most important diagnostic methods by which we can determine the health status of human and animals for certain diseases as anemia, leukemia and also detect the presence of the inflammations.Objectives: This study aimed to present an overview on the previous works from 1997 to 2018 on the varying effects of electromagnetic fields on haematological data in human and different species of experimental models by using different frequencies, intensities, and different sources of electromagnetic fields for different periods. The hematological parameters are fluctuating across the exposure period to the EMFs suggesting the possible induction of hazardous biological effects during the exposure to magnetic field. Conclusion:It can be concluded that exposure of human and experimental animals to EMFs cause harmful effects on blood cells. These effects were disturbance in haematological parameters depending on species, the sources of EMFs, frequencies, intensities and duration of exposure.
