Exposure to 1.8 GHz radiofrequency radiation increased protein oxidation markers in rat brain tissue, and garlic extract reduced that effect.

Plain English Summary

Summary written for general audiences

Researchers divided 66 albino Wistar rats into three groups to study oxidative damage from radiofrequency electromagnetic radiation and whether garlic extract could protect against it. After radiofrequency exposure, advanced oxidation protein product levels in brain tissue increased compared with the control group. Garlic administration alongside radiofrequency exposure significantly reduced those protein oxidation levels in brain tissue. No significant differences were found among the groups for malondialdehyde levels in brain tissue and blood, or for serum paraoxonase levels.

Why This Matters

The first group of rats received 1.8 GHz radiofrequency exposure at 0.4 W/kg specific absorption rate for one hour a day for three weeks. The second group received the same radiofrequency exposure plus 500 mg/kg garlic extract, and the third group served as the unexposed control. Serum nitric oxide levels significantly increased in both the radiofrequency-exposed group and the group that also received garlic. Garlic administration did not reduce the rise in serum nitric oxide, as there was no difference in serum nitric oxide levels between the radiofrequency-exposed group and the group that also received garlic.

Study Details

We aimed to study the oxidative damage induced by radiofrequency electromagnetic radiation (RF-EMR) emitted by mobile telephones and the protective effect of garlic extract used as an anti-oxidant against this damage.

The exposure of RF-EMR similar to 1.8 GHz Global system for mobile communication (GSM) leads to protein oxidation in brain tissue and an increase in serum NO. We observed that garlic administration reduced protein oxidation in brain tissue and that it did not have any effects on serum NO levels.
