Effects of static and ELF magnetic fields on free-radical processes in ratliver and kidney

The aim of the study was to evaluate the activities of the antioxidant enzy mes superoxide dysmutase (SOD, EC. 1.15.1.1), catalase (CAT, EC. 1.11.1.6), and glutathione peroxidase (GSH-Px, EC. 1.11.1.9) and the levels of maloni c dialdehyde (MDA), a phospholipid peroxidation product, in the liver and k idneys of male and female rats exposed to static (0.49-T) and extremely low -frequency (50-Hz, 0.018-T) magnetic fields. Extremely low frequency magnet ic fields increased all enzyme activities and MDA levels in both the liver and kidneys. In contrast, static magnetic field did not produce changes. Th e results of the study suggest that ELF magnetic fields affect free-radical processes in the liver and kidney.
