We aimed to investigate the protective effects of melatonin and 2.45GHz electromagnetic radiation (EMR) on brain and dorsal root ganglion (DRG) neuron antioxidant redox system, Ca 2+ influx, cell viability and electroencephalography (EEG) records in the rat. Thirty two rats were equally divided into four different groups namely group A1: Cage control, group A2: Sham control, group B: 2.45GHz EMR, group C: 2.45GHz EMR+melatonin. Groups B and C were exposed to 2.45GHz EMR during 60min/day for 30days. End of the experiments, EEG records and the brain cortex and DRG samples were taken. Lipid peroxidation (LP), cell viability and cytosolic Ca 2+ values in DRG neurons were higher in group B than in groups A1 and A2 although their concentrations were increased by melatonin, 2-aminoethyldiphenyl borinate (2-APB), diltiazem and verapamil supplementation. Spike numbers of EEG records in group C were lower than in group B. Brain cortex vitamin E concentration was higher in group C than in group B. In conclusion, Melatonin supplementation in DRG neurons and brain seems to have protective effects on the 2.45GHz-induced increase Ca 2+ influx, EEG records and cell viability of the hormone through TRPM2 and voltage gated Ca 2+ channels. © 2011 Elsevier Inc.
