In rats exposed to 2.45 GHz electromagnetic radiation, brain antioxidant vitamin levels fell, and selenium and L-carnitine supplementation appeared to reduce that effect.

Plain English Summary

Summary written for general audiences

Researchers divided thirty rats into five groups to study the effects of 2.45 GHz electromagnetic radiation on the brain's antioxidant system and EEG records. Exposed rats received 2.45 GHz electromagnetic radiation for 60 minutes per day for 28 days, after which EEG records and brain cortex samples were collected. Brain cortex concentrations of vitamin A, vitamin C, and vitamin E were lower in the exposed group than in controls, though these concentrations were increased by selenium and L-carnitine supplementation. L-carnitine appeared to have a more protective effect on vitamin concentrations than selenium.

Why This Matters

Lipid peroxidation levels were lower in the selenium-supplemented group and the L-carnitine-supplemented group than in the exposed-only group, suggesting those supplements may have reduced oxidative stress. Reduced glutathione levels were higher in the selenium group than in the cage control, sham control, and exposed-only groups. Beta-carotene levels did not change across any of the five groups.

Study Details

The present study was designed to determine the effects of 2.45 GHz EMR on the brain antioxidant redox system and electroencephalography (EEG) records in rat. The possible protective effects of selenium and L-carnitine were also tested and compared to untreated controls

Thirty rats were equally divided into five different groups, namely Group A1: Cage control, Group A2...

L-carnitine and selenium seem to have protective effects on the 2.45 GHz-induced decrease of the vitamins by supporting antioxidant redox system. L-carnitine on the vitamin concentrations seems to more protective affect than in selenium.
