detrimental effect of mobile phone electromagnetic field on permeability of blood-brain barrier

Background: exposure to different frequencies would have a profound effect on the brain tissue extract supernatant’s optical density and hexakis2methoxyisobutylisonitrile (99^mtcmibi) buildup. objectives: this study aimed to investigate the bloodbrain barrier permeability after electromagnetic field irradiation. methods: in this study, 150 male albino rats were randomly divided into 25 groups. they had an intraperitoneal injection of evans blue 24 hours before experiments. before 15 or 30min electromagnetic field (emf) irradiation (900, 1700, and 1900 mhz), 500 μci (18.5 mbq) of 99^mtc mibi was injected via the caudal vein. the rats decapitated 15, 30, 45, or 60 min after radiotracer injection to evaluate the brainspecific activity and brain tissue extract supernatant’s optical density. results: no significant difference was found between the groups in 60min postinjection activity after 15min emf radiation at 900, 1700, and 1900 mhz. the brainspecific activity with 30min emf radiation showed a significant increase in the 900 mhz group compared to others. brain/whole bodyspecific activity in all experimental groups after 15min emf radiation showed no significant differences. on the other hand, the brain/whole bodyspecific activity ratio with 30min emf radiation showed a significant increase in the 900 mhz group compared to other groups. a comparison between the brain tissue extract supernatant’s optical density in the experimental groups after 15 and 30min emf radiation showed no significant difference in evans blue accumulations in brains. conclusions: it may be concluded that mobile phone electromagnetic field radiation may increase the bloodbrain barrier permeability. as most humans use mobile phones for daily communications, all users around the world need to be advised of the effects of modern call devices.
