Abstract
The levels of blood lipid peroxidation, glutathione peroxidase, reduced glutathione, and vitamin C were used to follow the level of oxidative damage caused by 2.45 GHz electromagnetic radiation in rats. The possible protective effects of selenium and L-carnitine were also tested and compared to untreated controls.

Thirty male Wistar Albino rats were equally divided into five groups, namely Groups A(1) and A(2): controls and sham controls, respectively; Group B: EMR; Group C: EMR + selenium, Group D: EMR + L-carnitine. Groups B-D were exposed to 2.45 GHz electromagnetic radiation during 60 min/day for 28 days.

The lipid peroxidation levels in plasma and erythrocytes were significantly higher in group B than in groups A(1) and A(2) (p < 0.05), although the reduced glutathione and glutathione peroxidase values were slightly lower in erythrocytes of group B compared to groups A(1) and A(2). The plasma lipid peroxidation level in group A(2) was significantly lower than in group B (p < 0.05). Erythrocyte reduced glutathione levels (p < 0.01) in group B; erythrocyte glutathione peroxidase activity in group A(2) (p < 0.05), group B (p < 0.001), and group C (p < 0.05) were found to be lower than in group D.

In conclusion, 2.45 GHz electromagnetic radiation caused oxidative stress in blood of rat. L-carnitine seems to have protective effects on the 2.45-GHz-induced blood toxicity by inhibiting free radical supporting antioxidant redox system although selenium has no effect on the investigated values.
