The authors investigated the effect of RFR from cell phones on oxidative damage in the brains of rats, and the role of the antioxidant Ginkgo biloba (Gb) in the prevention of any such damage.

Eleven rats were exposed to RFR at 900 MHz for 1 hour a day for 7 days. The peak SAR of the brain was 2 W/kg and the average SAR of the whole body was 0.25 W/kg. Eleven rats were given Gb orally for 2 days before exposure and throughout exposure. Nine rats were given Gb but were not RFR-exposed, and 9 served as controls.

Oxidative damage from RFR exposure was suggested by the:

  1. increase in malondialdehyde and nitric oxide levels in the brain
  2. decrease in antioxidant enzyme levels (superoxide dismutase and glutathione peroxidase)
  3. increase in oxidant enzyme levels (xanthine oxidase and adenosine deaminase)
  4. increase in neuronal damage on pathology examination.

    These alterations were prevented by Gb treatment.

Forty rats were used in the experiment, but the methods statement says that 33 rats were used. There is no mention of the study being performed in a blinded fashion.
