Окиснювальна модифікація білків гепатопанкреасу і плазми крові коропа за інтоксикації важкими металами

Abstract

We have investigate the influence of lead (0,01, 0,2 and 0,5 mg/l) manganese (0,13, 2,6 and 6,5 mg/l), zinc (0,1, 2,0 and 5,0 mg/l) and copper (0,2 mg/l) ions for up 14 days upon the common carp (Cyprinus carpio L). The concentrations of metalls were 0,1, 2 and 5 MPC. We studied the level of protein oxidative modification of hepatopancreas and blood plasma. The results show that manganese ions caused the antioxidant protection of proteins. The zinc and copper ions increased the level of protein oxidation and the rate of changes, caused by the lead, wasn’t such significant as for other metalls. The level of protein oxidative modification in carp tissues may serve as an adequate test for estimation of the antyoxydant-prooxidant status of organism under the heavy metalls influence.
