[Stress ulcer-an experimental study (author's transl)]. 1977

R Kokoschka, and I Göber, and W Gebhart

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.

UI MeSH Term Description Entries
D008297 Male Males
D008407 Mast Cells Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR. Basophils, Tissue,Basophil, Tissue,Cell, Mast,Cells, Mast,Mast Cell,Tissue Basophil,Tissue Basophils

D004285 Dogs The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065) Canis familiaris,Dog
D005753 Gastric Mucosa Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.
