Histopathological and immunohistochemical study of rat brain tissue after exposure to mobile phone radiation

Abstract The health effects of cell phone radiation exposure are a growing public health concern. The aim of this study was to investigate the effects of mobile phone exposure at 940-MHz frequency magnetic field on temporal cortex. The study was carried out on 30 Wistar adult male rats (15–20 weeks, weighing 290 g). Thirty male rats were divided into five groups. Rats in the first group were exposed to 940-MHz frequency magnetic field for 30 min every day for a period of 30 days. The second, third, and fourth groups were exposed to 940-MHz frequency for 1, 2, and 3 h every day for a period of 30 days, respectively. The control group did not receive any exposure. Histopathological and immunohistochemical studies were used to determine the possible damages to brain tissue and blood-brain barrier (BBB). The findings of this study revealed that exposure to electromagnetic fields with a 940-MHz frequency has increased the permeability of BBB in all exposed groups. The increased period of exposure caused increased instances of histopathological changes in brain tissue.
