Comparative antioxidant enzyme study in freshwater fishes. II. Distribution of antioxidant enzymes and lipid peroxidation in omnivorous fish organs.
Comparative studies were performed on the activities of superoxide dismutases, catalase and glutathione peroxidase in organ homogenates from three omnivorous fishes, the barbel, crucian carp and common carp. The lipid peroxidation and protein contents of organ homogenates were also compared. These comparative measurements primarily provide control values for subsequent toxicological examinations. The highest total superoxide dismutase activities were found in the liver or roe, kidney, heart and spleen in every cases. The antioxidant enzyme activities and other studied parameters of the organ homogenates partly appear to depend on the feeding mode, but are rather characteristic of the fish variety.
