The effect of electromagnetic radiation on the rat brain: an experimental study

Abstract

AIm:The aim of this study is to determine the structural changes of electromagnetic waves in the frontal cortex, brain stem and cerebellum. mAterIAl and methOds: 24 Wistar Albino adult male rats were randomly divided into four groups: group I consisted of control rats, and groups II-IV comprised electromagnetically irradiated (EMR) with 900, 1800 and 2450 MHz. The heads of the rats were exposed to 900, 1800 and 2450 MHz microwaves irradiation for 1h per day for 2 months.results: While the histopathological changes in the frontal cortex and brain stem were normal in the control group, there were severe degenerative changes, shrunken cytoplasm and extensively dark pyknotic nuclei in the EMR groups. Biochemical analysis demonstrated that the Total Antioxidative Capacity level was significantly decreased in the EMR groups and also Total Oxidative Capacity and Oxidative Stress Index levels were significantly increased in the frontal cortex, brain stem and cerebellum. IL-1β level was significantly increased in the EMR groups in the brain stem.COnClusIOn: EMR causes to structural changes in the frontal cortex, brain stem and cerebellum and impair the oxidative stress and inflammatory cytokine system. This deterioration can cause to disease including loss of these areas function and cancer development.

Ecological study on the penetration of induction heating cookers and birth outcomes in Japan

“…Both malondialdehyde and protein carbonyl levels were increased in exposed animals. Eser et al (2013) employed adult male Wistar rats in their study on effects of 900, 1800, and 2450 MHz (1 h exposure/day; 2 months; 1.04 W/kg whole body SAR). The total antioxidative capacity and oxidative stress index levels were affected (decreased and increased respectively) in several structures of the brain.…”

Different methods for evaluating the effects of microwave radiation exposure on the nervous system

“…Staining the glial cells and neurons by various antibodies is particularly important for evaluating the histopathological effects at the cellular level. In this context, many researchers have preferred to determine the apoptosis in the neurons after exposure (Orendá cová et al, 2009;Carballo-Quintá s et al, 2011;Eser et al, 2013).…”

Health hazards with electromagnetic radiation

“…[19] Eser et al also studied the effect of electromagnetic waves in the frontal cortex, brain stem, and cerebellum of rats and found severe degenerative changes, extensively dark pyknotic nuclei, and shrunken cytoplasm in the electromagnetically irradiated group. [37] The preclinical laboratory studies have shown that, EMR may open the blood-brain barrier, increases the permeability of toxic substances into the brain, and impair spatial memory. [38] Long-term exposure of EMR radiation from GSM base station also caused impairment in the levels of neurotransmitter such as adrenaline, noradrenaline, and dopamine.…”
