Dasdag S, Akdag MZ, Aksen F, Bashan M, et al. (2004).

The authors investigated the effects of cell phone exposure on the fatty acid composition in phospholipids, malondialdehyde (MDA) concentration, p53 immune reactivity and histological structure of the rat brain. MDA production is a measure of lipid peroxidation. P53 is a tumour suppression protein that increases when cells are exposed to stress.

There were 8 rats in the exposed group and 8 in a sham group. Cell phones were placed 0.5 cm under the rats' cages. For the experimental group, the cell phones were activated 20 minutes a day, 7 days per week, for 1 month. The whole body average SAR was 0.52 W/kg.

There was no change in histological structure or in brain fatty acid composition in the exposed group. Likewise, p53 immune reactivity was not affected. MDA concentration, however, was significantly higher in the exposed brains.
