|continuous for 1 h/day for 3 weeks

|11 rats were simultanously exposed in a pie cage restrainer (for 12 rats) with an air hole
|monopole antenna was placed in the center of the pie cage restrainer; constrainers positioned radially around a 20 cm high antenna; distance between antenna and rat head: ca. 4 cm
|A sham exposure was conducted.
The serum nitric oxide levels were significantly increased in the exposed groups with and without garlic compared to the sham exposed group, but no significant difference was found between both exposure groups.
In the brain homogenates of the exposed group without garlic, the levels of malondialdehyde and the protein oxidation were significantly increased compared to the sham exposed group. An administration of garlic diminished these effects. Hence, no difference between the sham exposed group and the exposed group with garlic was observed in the brain tissue.
The authors conclude that exposure to a radiofrequency electromagnetic field of 900 MHz increased oxidative stress in rat brain and serum and that this effect was blocked in the brain by an administration of garlic.
