Extremely low frequency magnetic fields of 7 mT, 40 Hz, 30 min/day for 10 days caused a significant increase in lipid peroxidation and insignificant increases in hydrogen peroxide and free sulfhydryl groups as well as an insignificant decrease in the total protein content (as compared with the control group).
The same extremely low frequency magnetic fields but applied for 60 min/day caused insignificant increases in lipid peroxidation and hydrogen peroxide as well as significant increases in free sulfhydryl groups and protein concentration in the brain homogenates (as compared with the control group).
The effect of extremely low frequency magnetic field irradiation on oxidative stress parameters depended on the duration of magnetic field exposure.
