To investigate the effects of an exposure to microwaves on the cognitive performance as well as oxidative stress level in the blood of rats.
Rats were exposed (n=6) or sham exposed (n=6).
ばく露時間: 2 h/day, 5 days a week for 30 days
|ばく露時間||2 h/day, 5 days a week for 30 days|
|Distance between exposed object and exposure source||1 m|
|チャンバの詳細||during exposure rats were restrained in a closed box (30 cm x 20 cm x 15 cm) divided in 4 compartements with holes of 1 cm for ventilation; 6 rats were placed within the device in two such boxes simultaneously|
|ばく露装置の詳細||GTEM cell was a pyramidal tapered, dual terminated section with outer cell dimension of 220 cm Œ 120 cm Œ 80 cm; microwave chamber was lined with absorbers to minimize reflections|
|Sham exposure||A sham exposure was conducted.|
In the elevated plus maze and the Morris water maze, the spatial memory and learning was significantly decreased in the exposed group in comparison to the sham exposed group.
In the exposed group the levels of the lipid oxidation and protein oxidation were significantly increased compared to the sham exposure group. No significant difference was observed regarding the concentration of reduced glutathione.
The authors conclude that exposure to microwaves could lead to cognitive impairments in rats and could induce oxidative stress.
