To study the effect of acute ultrahigh frequency electromagnetic field exposure on non-enzymatic antioxidant defense and lipid and protein oxidative damage in the rat frontal cortex and hippocampus.
A total of 31 rats were divided by age into three groups (30, 80, and 210 days) and exposed.
ばく露時間: repeated daily exposure, 7.5 h per day, for 6 days
|ばく露時間||repeated daily exposure, 7.5 h per day, for 6 days|
|Additional information||vertical polarisation|
|Distance between exposed object and exposure source||20 cm|
|チャンバの詳細||The animal exposure cage (total diameter 93 cm, height 33 cm in the center and 24 cm at the periphery) was divided into four compartments (1276.27 cm² each) placed around an inner compartment (1256.64 cm², r = 20 cm) and was made of wood (floor and inner walls) and transparent plastic (lining the floor and outer wall) covered by a galvanised steel net (1.5 x 1.5 cm mesh).|
|ばく露装置の詳細||The mobile phone was positioned in the center of the middle compartment, and the extremity of the antenna was in contact with the floor. The animals were placed in one of the compartments, and their distance from the antenna varied from 20 to 45 cm.|
|Sham exposure||A sham exposure was conducted.|
|Additional information||The sham exposure cage was placed 40.5 cm away from the real exposure cage.|
No changes in lipid and protein damage, and also in non-enzymatic antioxidant defense were found in frontal cortex or hippocampus. These data indicate that acute ultrahigh frequency electromagnetic field exposure is not able to produce detectable oxidative stress in rats from any age tested.
