title: [The antioxidant defense system and trace elements].
abstract: The survey presents current knowledge on antioxidant defence systems and on the role and meaning of trace elements in these systems. From this point of view the most important elements include transient metal iron and copper, and there after selenium, zinc and manganese. They represent essential components of antioxidant enzymes or transport proteins which participate in intermediation of antioxidant reactions of ceruloplasmin, SOD, GSPx, and catalase. Both deficiency, and in some cases also excess of mentioned trace elements may contribute to oxidative stress. (Tab. 3, Fig. 3, Ref. 27.)
