Abstract

1. 1. Comparative studies were made of the activities of Cu, Zn-superoxide dismutase, Mnsuperoxide dismutase, catalase and glutathione peroxidase in organ homogenates from two herbivorous (grass carp and silver carp) and three omnivorous fish (barbel, crucian carp and common carp). 2. 2. The protein contents and lipid peroxidation of the organ homogenates were also compared. These comparative measurements provided control values for subsequent toxicological examinations. 3. 3. For the herbivorous fish, the highest total superoxide dismutase activity was observed in the kidney, followed in turn by the liver or spleen. In contrast, the highest total superoxide dismutase activity in the barbel was found in the roe, in the crucian carp in the liver, and in the common carp in the liver too. 4. 4. The quantitative distributions of the two peroxide metabolism enzymes glutathione peroxidase and catalase in the organ homogenates present very varied pictures. 5. 5. The results of the lipid peroxidation are similarly difficult to fit into one framework, even for fish following the same diet. It appears that the enzyme activities mentioned in points 4 and 5, together with the lipid peroxidation, depend not on the species, but on the variety.
