title: A comparative study of some more important experimental animal peroxide metabolism enzymes.
abstract: 1. We have studied and compared the peroxide metabolism enzymes (SOD, P and C) of the main organs of fresh-water mollusc, chicken, mouse, guinea-pig, rabbit, cat and dog. 2. The liver exhibited the highest SOD activity. The enzymatic activities of the organ homogenates of the guinea-pig stand out in comparison with the values for the other homogenates examined. 3. The liver, kidney and total brain homogenates of the chicken and the vertebrates display no, or only a very low P activity. The highest P activities were measured in the haemolysates. 4. The C and SOD values exhibit a certain parallelism. 5. The peroxide metabolism enzyme activities calculated by utilizing the protein measurements permit the establishment of a more realistic enzymatic activity.
