Exposure to 900 MHz radiofrequency radiation raised markers of oxidation in rat brain tissue, and garlic reduced these effects.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to a 900 MHz electromagnetic field at a whole body average specific absorption rate of 1.08 W/kg for 1 hour per day for 3 weeks. Malondialdehyde and advanced oxidation protein product levels increased in rat brain tissue after electromagnetic field exposure. Nitric oxide levels in the brain showed no significant difference, but serum nitric oxide increased significantly after exposure, and garlic did not reduce that increase. The researchers also tested orally administered garlic powder at 500 mg/kg/day and found it had a protective effect against the oxidative stress seen in brain tissue.

Why This Matters

The study measured oxidative stress markers in brain tissue and serum of rats exposed to a 900 MHz electromagnetic field. The researchers described their overall finding as suggesting a significant increase in brain lipid and protein oxidation after electromagnetic radiation exposure. Garlic reduced the rise in malondialdehyde and advanced oxidation protein product in brain tissue, but did not affect the rise in serum nitric oxide.

Study Details

The aim of this study is to observe Effect of 900 MHz radiofrequency radiation on oxidative stress in rat brain and serum

In this study, we examined the oxidative stress in the brain tissue and serum of rats that resulted ...

We found that malondialdehyde (MDA) (p < 0.001) and advanced oxidation protein product (AOPP) (p < 0...

Our results suggest that there is a significant increase in brain lipid and protein oxidation after electromagnetic radiation (EMR) exposure and that garlic has a protective effect against this oxidative stress.
