Mechanism of stress ulcer. Influence of alpha-adrenergic blockade on stress ulceration and gastric mucosal energy metabolism. 1978

R Menguy, and Y F Masters

In previous reports from this laboratory, it has been proposed that stress ulceration results from a severe gastric mucosal energy deficit due to shock-induced mucosal ischemia. In the experiments described in this report, the hypothesis was further tested by studying stress ulceration and gastric mucosal energy metabolism in rabbits subjected to hemorrhagic shock with or without the concomitant administration of an alpha-adrenergic blocking agent. Our data show that stress ulceration and gastric mucosal energy deficits are significantly less severe when shock is combined with alpha-adrenergic blockade.

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. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
