Extremely low frequency magnetic field induces oxidative stress in mouse cerebellum.

Published in: Gen Physiol Biophys 2011; 30 (4): 415-421

Aim of study (acc. to author)

To study whether an extremely low frequency magnetic field induces lipid peroxidation and reactive oxygen species in mouse cerebellum.

Main outcome of study (acc. to author)

After exposure to the 60 Hz extremely low frequency magnetic field at 2.3 mT for three hours, there was a significant increase in malondialdehyde and hydroxyl radical levels. Exposure significantly induced concomitant increase in superoxide dismutase enzyme activity without alteration in glutathione peroxidase enzyme activity. While glutathione contents were not altered, ascorbic acid level was significantly decreased by extremely low frequency magnetic field exposure.
These results indicate that the extremely low frequency magnetic field may induce oxidative stress in mouse cerebellum.
