Impact of Electromagnetic Field Generated by Mobile Phone on Prooxidant/Antioxidant Balance in Frontal Brain Cortex of Rats

In this paper the potentially harmful impact of electromagnetic field generated by mobile phone $(\mathbf{f}=\mathbf{900\ MHz})$ on the prooxidant/antioxidant balance in frontal brain cortex of male rats was estimated by means of analysis of the contents of markers of oxidative stress and membrane lipid peroxidation, as well as the activity of selected antioxidant enzymes. It was concluded that 4-week lasting exposure (4 minutes daily) of rats to electromagnetic field with physical parameters generated by such mobile phone causes in frontal brain cortex an increase in intensity of the process of membrane lipids peroxidation without stimulation of oxidative stress, with accompanying compensatory decrease in the activity of most of analyzed antioxidant enzymes except of catalase, probably due to excessive consumption.
