[Active HCO3(-)Secretion in the gastric-mucosa. A causal factor in peptic ulcer disease? (author's transl)]. 1980

B Simon, and P Müller, and H Kather

Studies during the last few years have revealed evidence of active secretion of HCO3(-) in the gastric mucosa both in vitro and in vivo. This transport process presumably has considerable importance for the protection of the gastric epithelium, disturbance must be considered a causal factor in the pathogenesis of gastric ulcer. The HCO3(-)-transport is subject to autonomic control. It is inhibited by drugs with an ulcerogenic action and stimulated by anti-ulcerogenic prostaglandins. The results available up to now raise the probability of the physiologic and pathophysiologic significance of the HCO3(-)-transport system. Clinical investigations must demonstrate the therapeutic efficacy of control of the alkali secretion in the gastric mucous membrane.

D010437 Peptic Ulcer Ulcer that occurs in the regions of the GASTROINTESTINAL TRACT which come into contact with GASTRIC JUICE containing PEPSIN and GASTRIC ACID. It occurs when there are defects in the MUCOSA barrier. The common forms of peptic ulcers are associated with HELICOBACTER PYLORI and the consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).

D011453 Prostaglandins A group of compounds derived from unsaturated 20-carbon fatty acids, primarily arachidonic acid, via the cyclooxygenase pathway. They are extremely potent mediators of a diverse group of physiological processes. Prostaglandin,Prostanoid,Prostanoids
D002254 Carbonates Salts or ions of the theoretical carbonic acid, containing the radical CO2(3-). Carbonates are readily decomposed by acids. The carbonates of the alkali metals are water-soluble; all others are insoluble. (From Grant & Hackh's Chemical Dictionary, 5th ed) Carbonate
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.

D001692 Biological Transport The movement of materials (including biochemical substances and drugs) through a biological system at the cellular level. The transport can be across cell membranes and epithelial layers. It also can occur within intracellular compartments and extracellular compartments.
