Intestinal ischemia: morphological features--II.

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.

Intestinal occlusion: morphological features.

In this research we studied the possible relationships between the level and the distribution of peroxidase-catalase activity and the degree of the morphological changes in the intestinal wall during mechanical occlusion. These researches have really proved that the increase of the peroxidase-catalase enzymes correlate proportionally with the damage of intestinal wall.

Intestinal ischemia: morphological features--I.

In this research we studied the interrelationships between the progression of morphological damage and leucocyte populations in the last ileal loop after blockage of blood supply subsequent to arterial and venous occlusion. Our morphological data on the staging of the ileal wall damage agree with those reported in literature. In addition we described that in the ischemic loop the number of lymphocytes appear decreased and polymorphonuclear cells degranulate actively.
