title: Intestinal ischemia: morphological features--II.
abstract: Superoxide radicals produced during acute intestinal ischemia are biochemically related with the presence of hydrogen peroxyde. In this study we have investigated the distribution of peroxidase-catalase activity, histochemically determined, in the ischemic ileal wall. In the rat, complete arterial and venous occlusion produced a progressive increase in extra-vascular peroxidase-catalase activity with a maximum corresponding to the ileal wall. Probably the tissue peroxidase-catalase activity is related to massive degranulation of polymorphonucleates.
