Morphofunctional disorders in the small intestine in acute occlusive ileus

: Activity of liminal and membrane enzymes and morphologic state of small intestinal mucosa were studied in experimental acute occlusive ileus in rats. It was established that degenerative alterations of intestinal mucosa epithelium above the site of obstruction are more pronounced than in the distal part. The activity of membrane enzymes (invertase) remained unaltered during 72 hours after the obturation, however, serious morphologic damage of the intestinal mucosa epithelium and sharp suppression of the liminal digestion were observed.
