    Notes: Summary The morphology and chronology of an absolute ischemia was investigated on the small intestine of man and rat. It could be shown that the morphogenesis of ischemic damage to the intestinal mucosa in man does not differ from that in the rat. However, there are crucial and in therapeutic terms significant differences in the time course of the ischemic damage to the intestinal mucosa. Whereas in the small intestine of the rat, the first appreciable alterations — detachment and disruption of the lining epithelium at the villous tip — are already to be observed after absolute ischemia lasting 15 min, in the human small intestine the same lesions only occur after 4 h. A comparable complete necrosis of the small intestinal mucosa was detected in the rat after 7-h ischemia, and in man after 44-h ischemia.

    Description / Table of Contents: Zusammenfassung An 8 Bastardhunden wurden ausgedehnte oropharyngeale Weichteildefekte durch mikrochirurgisch transplantierte, kontramesenterial eröffnete Dünndarmsegmente gedeckt. Über einen Beobachtungszeitraum von 12 Monaten zeigen unsere klinischen, histologischen, histochemischen und Scannerelektronenoptischen Untersuchungen eine Zunahme der funktionellen Anpassung der Darmschleimhaut mit Abflachung und Verbreiterung der Zotten, Rückgang der Schleimproduktion, Unverletzlichkeit bei mechanischer Belastung und gleichbleibende Konsistenz. Sie dient als adäquate Mundmucosa.
    Notes: Summary In eight mongrel dogs large defects in the cheek, mandible, floor of the mouth, and the tongue were covered with microsurgicatty transplanted bowel segments opened along the antimesenteric border. After transplantation our clinical, histological, histochemical, and scanner-electronoptic findings show for up to 1 year an increasing functional adaptation of the intestinal lining with flattening and widening of the villi, reduction of the mucous production, persisting softness, and invulnerability when under stress mechanically. Free bowel grafts serve as an adequate oral lining.
