A comparison of the acid and gastrin secretory responses to hypoglycaemia and meals in duodenal ulcer with and without acid hypersecretion to pentagastrin. 1976

S K Lam, and W Sircus

In 60 uncomplicated duodenal ulcers (DU), maximum acid output (MAO) and acid output following insulin hypoglycaemia (IAO) were measured, and in 30 patients also the serum gastrin responses to insulin and to standard meals, In 7 normal controls, all 4 items were measured. Thirty-six of the DU had MAO within normal limits (normosecretors) and 24 were hypersecretors. Hypoglycaemic vagal response was higher in all DU than in normals and was, in normo-secreting DU associated with an abnormally large functioning G cell mass. This mass is not increased in hypersecreting DU and the greater vagal capacity is related to a supranormal parietal cell mass. An unknown mechanism, perhaps genetic, directs the trophic effects of an increased vagal drive to the gastrin cell mass in one group of DU and to the parietal cell mass in the other.

UI	MeSH Term	Description	Entries
D007003	Hypoglycemia	A syndrome of abnormally low BLOOD GLUCOSE level. Clinical hypoglycemia has diverse etiologies. Severe hypoglycemia eventually lead to glucose deprivation of the CENTRAL NERVOUS SYSTEM resulting in HUNGER; SWEATING; PARESTHESIA; impaired mental function; SEIZURES; COMA; and even DEATH.

D007328	Insulin	A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

D010418	Pentagastrin	A synthetic pentapeptide that has effects like gastrin when given parenterally. It stimulates the secretion of gastric acid, pepsin, and intrinsic factor, and has been used as a diagnostic aid.	Acignost,Gastrin Pentapeptide,Peptavlon,Pentapeptide, Gastrin

D005755	Gastrins	A family of gastrointestinal peptide hormones that excite the secretion of GASTRIC JUICE. They may also occur in the central nervous system where they are presumed to be neurotransmitters.	Gastrin
