Вивчення антиоксидантно-прооксидантного статусу крові коропа при дії йонів цинку в сублетальних концентраціях

Abstract

The influence of exposure to 0,1, 2,0 and 5,0 mg zinc ions/l for up 14 days on the antyoxidant-prooxidant status of carp blood has been investigated. The results show that the zinc concentration 0,1 mg/l activates the compounds of atioxidante protection systeme: catalase, ceruloplasmin, reduced glutathione. The doses 2,0 and 5,0 mg zinc/l doses provokes the increase of peroxidation activity in the blood (the content of malonic dialdegid, lipide hydroperoxides, glycosidative hemoglobin) and the decrease of antyoxidant activity of blood. Thуs the dose of 0,1 mg/l is the most propitious for the stimulation of protection systems in the carp blood.
