title: Effects of metal ions on the antioxidant enzyme activities, protein contents and lipid peroxidation of carp tissues.
abstract: 1. Studies were performed regarding the effects of CuSO4 in concentrations of 5, 10, 25 and 50 ppm and ZnSO4 in concentrations of 10 and 100 ppm on the antioxidant enzyme activities, lipid peroxidation and protein contents of tissues of common carp (Cyprinus carpio morpha L.) exposed to these pollutants for 24 hr. 2. The results demonstrated that CuSO4 was more toxic than ZnSO4 and that both treatments brought about significant changes in these parameters in carp hepatopancreas (liver), gill and white muscle. 3. An increase of the CuSO4 concentration led to significant decreases in the antioxidant enzyme activities, except that of glutathione peroxidase, which was increased significantly, and significant increases in the lipid peroxidation and protein contents. 4. An increase of the ZnSO4 concentration led to slight changes in the antioxidant enzyme activities, lipid peroxidation and protein contents of carp tissues.
