Effects of electromagnetic radiation from a cellular telephone on the oxidant and antioxidant levels in rabbits. med./bio.

Published in: Cell Biochem Funct 2002; 20 (4): 279-283

Aim of study (acc. to author)

To investigate the influence of electromagnetic irradiation of a GSM mobile telephone (900 MHz) on oxidant and antioxidant levels in the serum and the brains of rabbits.

Background/further details

16 male adult rabbits were utilized.

Main outcome of study (acc. to author)

The exposure to electromagnetic field had no significant effect on the antioxidant enzyme level in the brains of rabbits.
However, the serum superoxide dismutase activity increased, and the serum nitric oxide levels decreased in electromagnetic field exposed animals compared to the sham exposure group.
