To study the activities of the antioxidant enzymes superoxide dismutase, catalase, and glutathione peroxidase and the levels of malondialdehyde in the liver and kidneys of male and female rats (n=40) exposed to static magnetic fields and extremely low frequency magnetic fields.
|Chamber||exposure chamber: 22 x 22x 22 cm centered between the electromagnet poles.|
|Setup||The animals were placed in well ventillated Plexiglas holder restraining tubes (17 cm in length, 11.5 cm in diameter).|
|Additional info||Control animals were treated in the same way but were not exposed to MF.|
Extremely low frequency magnetic fields increased all enzyme activities and malondialdehyde levels in both the liver and kidneys. In contrast, static magnetic field did not produce changes.
The data indicate that extremely low frequency magnetic fields affect free radical processes in the liver and kidney.
