Effects of Low-Frequency Electromagnetic Field on Oxidative Stress in Selected Structures of the Central Nervous System

Table 5

Concentrations of oxidative stress biomarkers: malondialdehyde (MDA) and total oxidant status (TOS); activity of antioxidant enzymes: superoxide dismutase (SOD) and isoenzymes (SOD-Mn, SOD-CuZn), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), and glutathione S-transferase (GST); and concentration of nonenzymatic antioxidants—total antioxidant capacity (TAC) in the striatum homogenates from rats exposed to low-frequency electromagnetic field (group A) and sham-exposed rats (control group) (group C) with results of ANOVA for all examined groups (A, C, M, and A + M) and post hoc NIR test for two selected groups: A and C.
