" Low-intensity electromagnetic radiation led to a gradual increase in the malondialdehyde concentration in rat plasma and erythrocytes, while the total antioxidant capacity was slightly lower. The exposure of rats to high-intensity electromagnetic radiation resulted in a sharp rise in the malondialdehyde concentration in plasma for the first week of the experiment and gradually decreased until the end of the experiment to a level slightly higher than the level for the control group. The malondialdehyde concentration in erythrocytes was higher than in the control animals at the second and fourth weeks of irradiation. Changes in the total antioxidant capacity in plasma and erythrocytes were negligible and statistically insignificant. The dynamics of superoxide dismutase activity demonstrate a two-phase response to prolonged (up to 4-week) exposure to electromagnetic radiation of 460 MHz. At the first phase (a compensatory stage), an increase occurred in the activity of superoxide dismutase against the background of an increased level of lipid peroxidation; at the second phase (the adaptive stage), superoxide dismutase activity decreased to a stable level below the control." |
