Introduction: The use of cell phones is widespread and there are public concerns regarding its possible deleterious effects on human health especially on the pregnancy outcomes. In this study, structural changes of the placenta after applying the cell phone radiation were examined in the mice model.  

Materials and methods: For this work, 40 pregnant Balb/C mice were randomly allocated to one control and one experiment groups. The experimental animals were exposed to cell phone fields with a carrier frequency of 915 MHz, for 4 h a day continuously, during 5-17 days of gestation. On the 18^th day of pregnancy, the half of each groups were sacrificed and placentas specimens were taken for histological studies. In the rest of animals, the neonates were counted and the offspring’s survival rates were determined. Also, morphometrical aspects of the placentas were studied.

Results: There were no morphometric as well as light microscopic changes in the placentas between two groups. Ultrastructural results of the treated group revealed a slight elevation in the number of intra cytoplasmic droplets in the labyrinth interhemal membrane. In addition, in the electromagnetic fields (EMFs) exposed mice, the nucleus of the cytotrophoblast cells occasionally was large in the size and irregular in the shape and also had compact nucleoli. Finally, the survival rate of the neonate was not significantly affected by cell phone exposition.

Introduction: There are general concerns about the hazardous impacts of the cell phones radiation on the human health. In this study, the structural and biochemical changes of the mice kidney were assessed after cell phone exposure in.

Materials and methods: A total of 40 Balb/C mice were randomly divided into the control and experimental groups. The experimental group exposed to cell phone devices with a carrier frequency of 915 MHz, for 4 h a day during 60 consecutive days. After mobile phone exposure, the blood samples and also the renal tissues were taken out for histological and biochemical examinations.

Results: The histological results revealed no light microscopic changes in the kidneys between two groups. Necrosis of the renal tubules epithelium was seen in some of the the sections belonging to the both control and experimental groups. Also, in the mice exposed to cell phone fields, the serum levels of creatinine, urea, chloride and total protein were not significantly altered. Although the serum levels of sodium and bicarbonate showed a significant increase, but the activity of alkaline phosphatase revealed no significant changes in comparison with control group. In addition, there are no morphometric, ultra-structural or light microscopic changes in the kidneys between two groups. In the treated animals; the mitochondria were often deformed in the shape and the cytoplasm of the renal tubules was folded in an abnormal manner.

Conclusion: Based on the study, it could conclude that there is no toxic effect on the mice kidneys after exposure to cell phone radiation.
