30 male rats were divided into five groups: 1) cage control; 2) sham exposure; 3) 2.45 GHz exposure; 4) 2.45 GHz exposure + selenium; 5) 2.45 GHz exposure + L-carnitine. The first dose of selenium and L-carnitine was administered 24 h before exposure.
|Exposure duration||continuous for 1 h/day on 28 days|
|Repetition frequency||217 Hz|
The lipid peroxidation levels in plasma and erythrocytes were significantly higher in the exposure (group 3) than in the control groups (group 1 and 2), although the reduced glutathione and glutathione peroxidase values were slightly lower in erythrocytes of the exposure group compared to the control groups.
The data showed reduced erythrocyte glutathione levels in the exposure group compared to group 5 (exposure + L-carnitine). Erythrocyte glutathione peroxidase enzyme activity in sham exposure group, exposure group, and "exposure + selenium" group (group 4) were lower than in group 5 (exposure + L-carnitine).
The authors conclude, that 2.45 GHz electromagnetic field exposure caused oxidative stress in blood of rats. L-carnitine seems to have protective effects on the 2.45-GHz-induced blood toxicity. Selenium has no effect on the investigated values.
