To study the effects of GSM base transceiver station electromagnetic irradiation on oxidative stress and generation of free radicals in rats.
9 rats were exposed, 9 rats were sham-exposed.
|ばく露時間||repeated daily exposure, 7 h/day, for 8 days|
|Repetition frequency||217 Hz|
|チャンバの詳細||general purpose EM shielded chamber|
|ばく露装置の詳細||The test subjects were placed in two transparent Plexiglas metabolic cages positioned side by side and closer to the input port of the GTEM cell. The rats (five and four) were free to move inside a volume of 24 cm x 34 cm x 12.5 cm (W x L x H). The electric field was perpendicular to the plane on which the rats were located.|
|Sham exposure||A sham exposure was conducted.|
When electromagnetic fields at a power density of 3.67 W/m² were applied malondialdehyde level increased and glutathione concentration decreased significantly. Additionally, there was a less significant increase in superoxide dismutase activity under exposure.
The data indicate that exposure to electromagnetic fields at base station frequency may modulate the oxidative stress in rats.
