title: [Stress ulcer-an experimental study (author's transl)].
abstract: This experimental study demonstrates by means of electromagnetic flow measurements that hypovolaemic shock results in a significant decrease in gastric flow. 14 mongrel dogs were subjected to haemorrhagic shock for 3 or 4 hours. Significant histological changes are seen in the gastric mucosa as a result of the haemodynamic changes, especially when the duration of shock was 4 hours. All stages of stress ulcer from the superficial erosion to deep ulcers were documented. The possibility that the mast cell plays a pathogenetic role as mediator in the origination of a stress ulcer is considered.
