When animals are injured by nitrogen dioxide the activity of the antioxidation ferments of catalase and superoxiddismutase is reduced by 27,5 and 30,7% correspondently. Carbon monoxide reduces the activity of catalase by 43,7% and do not influence the activity of superoxiddismutase. Enomelanine and pectine recreate the activity of ferments superoxiddismutase and catalase under conditions of oxidant stress induced by nitrogen dioxide and carbon monoxide.
