A Study of the Effects of Electromagnetic Field on Islets of Langerhans and Insulin Release in Rats

Nowadays, modern technologies are increasingly used in domestic industries, home appliances, and cell phones. This has highlighted the necessity of protecting human beings from the impacts of electromagnetic fields (EMFs) as a new challenge. Therefore, the present study aimed to find out what impacts EMFs have on the structure of Langerhans Islets and the insulin secretion levels in rat. Fourteen 12-week-old male rats were selected randomly: 5 as a control group and 9 as an experimental group. The experimental group was exposed to an EMF produced by an electromagnetic device, with a frequency of 50 Hz and intensity of 3 mT 4 h a day for 6 weeks. At the end of the 6 weeks, blood and pancreas tissue samples were taken for enzyme linked immunosorbent assay (ELISA) test and preparation for microscopic studies. Results showed that in EMF exposed group insulin level was decreased (P < 0.05), which was associated with decreased area and perimeter of pancreatic islets (P < 0.05). Exposure to EMF impacts insulin secretion by influencing the size of pancreatic islets.
