title: Comparative studies on superoxide dismutase and catalase activities in livers of fish and other Antarctic vertebrates.
abstract: The activities of superoxide dismutase and catalase in livers of fish and other Antarctic vertebrates were examined. Significant differences between superoxide dismutase activities in livers of white-blooded and red-blooded fish species were observed. Superoxide dismutase seems to be involved more than catalase in protection processes against cell damage caused by oxygen free radicals.
