Factors affecting maximal acid secretion.
The mechanisms by which different factors affect the maximal acid secretion of the stomach are discussed with particular reference to nationality, sex, age, body weight or lean body mass, procedural details, mode of calculation, the nature, dose and route of administration of a stimulus, the synergistic action of another stimulus, drugs, hormones, electrolyte levels, anaemia or deficiency of th...
متن کاملMaximal Gastric Acid Secretion in the Dog
As bstract. The reason for increased maximal acid secretory capacity in some patients with duodenal ulcer is uncertain. We postulated that chronically increased cephalic-vagal stimulation may be a cause of increased maximal acid output. To study this, we prepared six male, mongrel dogs with a vagally innervated gastric fistula, a vagally denervated fundic (Heidenhain) pouch, and a cervical esop...
متن کاملHelicobacter pylori virulence factors affecting gastric proton pump expression and acid secretion.
Acute Helicobacter pylori infection of gastric epithelial cells and human gastric biopsies represses H,K-ATPase α subunit (HKα) gene expression and inhibits acid secretion, causing transient hypochlorhydria and supporting gastric H. pylori colonization. Infection by H. pylori strains deficient in the cag pathogenicity island (cag PAI) genes cagL, cagE, or cagM, which do not transfer CagA into h...
متن کاملHyperglycemic athymic nude mice: factors affecting in vitro insulin secretion.
The strain of athymic nude male mice (ANM) developed at the University of Southern California (USC) exhibits spontaneous hyperglycemia and relative hypoinsulinemia in vivo. To investigate factors that influence insulin secretion in this animal model of non-insulin-dependent diabetes mellitus, we utilized the isolated perfused mouse pancreas of the ANM-USC and control BALB/c mice. We compared in...
متن کاملFactors affecting the secretion of staphylococcal enterotoxin A.
The biosynthesis of enterotoxin A by replicating and nonreplicating cells was investigated. Unlike enterotoxin B, a secondary metabolite, enterotoxin A secretion resembled that of a primary metabolite by being secreted during the exponential phase of growth. The amount of toxin produced per unit of growth was not influenced by NaCl, NaNO(2), or NaNO(3). Several surfactants increased toxin secre...
