Abstract: The influence of CCl₄ on the activity of superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), the value of the total antioxidant status (TAS), and the concentration of malonic dialdehyde (MDA) and glutathione (GSH) was monitored in plasma or whole blood of rabbits. The administration of CCl₄ caused the increase of the SOD activity to approximately 150 % and the decrease in the activity of GPx and GR by about 50 %. These changes were accompanied with the increase in TAS value and MDA concentration and the decrease of GSH concentration. The effect of CCl₄ was suppressed by the previous 7 days lasting or simultaneous administration of vitamin E. Oxidative stress caused by CCl₄ was accompanied by the development of reactive oxygen forms, especially superoxide radical anion.

Keywords: antioxidant enzymes - glutathione - total antioxidant status - malonic dialdehyde - vitamin E
