title: Comparative antioxidant enzyme study in freshwater fishes. I. Distribution of superoxide dismutase, peroxide-decomposing enzymes and lipid peroxidation in herbivorous fishes.
abstract: The activities of Cu,Zn-superoxide dismutase, Mn-superoxide dismutase, catalase and glutathione peroxidase were comparatively studied in organ homogenates from two herbivorous fishes, viz., the grass carp and the silver carp. 2. The protein contents and lipid peroxidation of organ homogenates were also compared. The comparative measurements primarily provide control values for subsequent toxicological examinations. 3. The highest total superoxide dismutase activities were found in the kidney, spleen and liver in the grass carp, and in the kidney and liver in the silver carp. 4. The antioxidant enzyme activities and other parameters of the organ homogenates appear to be independent of the feeding mode, but are rather characteristic of the fish variety.
