The effect of exposure of rats during prenatal period to radiation spreading from mobile phones on renal development

Abstract

Background: The aim of this study was to investigate the effects of exposure to a 900-MHz electromagnetic field (EMF) produced by mobile phones on the renal development of prenatal rats. Histopathological changes and apoptosis in the kidneys, together with levels of urea, creatinine and electrolyte in serum were determined. Methods: A total of 14 Sprague-Dawley rats were studied. Pregnant rats were divided into two equal groups: a control group and an EMF-exposed group. The study group was exposed to 900-MHz of EMF during the first 20 days of pregnancy, while the control group was unexposed to EMF. Sections obtained from paraffin blocks were stained for caspase-3 by immunohistochemistry, hematoxylin-eosin and Masson's trichrome. Results: Mild congestion and tubular defects, and dilatation of Bowman's capsule were observed in the kidney tissues of rats in the exposed group. Apoptosis was evaluated using anti-caspase-3; stronger positive staining was observed in the renal tubular cells in the study group than those of the control group. Although there was a significant difference between the study and control groups in terms of K + level (p50.05), no significant difference was observed in the other parameters studied (p40.05). Conclusion: Our study shows that the electromagnetic waves propagated from mobile phones have harmful effects on the renal development of prenatal rats.

The effect of 900MHz Electromagnetic Field on the Cerebellum: A Histopathological Investigation

“…EMA grubuna ait kafeslerin ortasına 20 gün süreyle ve 24 saat boyunca 900 MHz radyo frekansı radyasyonu üreten dijital bir sinyal üreteci olan dijital modülasyon sinyal üreteci (Anritsu MG3670 B tipi, Japonya) cihazının anteni konulmuştur. [21] Dijital modülasyon sinyal üreteci cihaz, mobil iletişim için küresel sistemlerin maruziyetini temsil etmek amacıyla pik değeri, pozlama sırasında 2 Watt (W)'da sabitlenmiştir. Taşıyıcı frekansı 900 MHz, modülasyon frekansı 217 Hz, darbe genişliği 577 μsn ve maksimum tepe gücü 2 W olarak ayarlandı.…”

Effects of folic acid on rat kidney exposed to 900 MHz electromagnetic radiation

“…It was reported that mobile phone usage has various biological effects on the kidney. At this point; it was proposed by Bedir et al that the electromagnetic waves originating from the mobile phones may exert hazardous effects on the development of kidneys in rats [ 36 ]. Moreover; it was reported by Ulubay et al that EMR can be counted among the stress factors which may cause extensive renal damage [ 12 ].…”

The effect of prenatal exposure to 1800 MHz electromagnetic field on calcineurin and bone development in rats

“…reported that an electromagnetic field (EMF) may have side effects in various tissues and cells [2][3][4] . Although some studies have shown tissues with proliferative epithelial cells during and after pregnancy, reproductive cells and tissues of the hematopoietic system seem potentially sensitive to EMF exposure [5][6][7] .…”
