The nature and extent of growth hormone-release inhibiting hormone (GH-RIH, somatostatin)-induced inhibition of pancreatic secretion of bicarbonate and protein, an index of enzyme secretion, were studied by administration of exogenous secretin or cholecystokinin (CCK) and of a number of stimulants for endogenous release of these hormones in fasted pancreatic fistula dogs with and without an inf...

Carbonic anhydrase (CA) is strongly expressed in the duodenum and has been implicated in a variety of physiological functions including enterocyte HCO(3)(-) supply for secretion and the "sensing" of luminal acid and CO(2). Here, we report the physiological role of the intracellular CAII isoform involvement in acid-, PGE(2,) and forskolin-induced murine duodenal bicarbonate secretion (DBS) in vi...

background: coeliac disease (cd) is characterized by malabsorption resulting from inflammatory injury to the mucosa of the small intestine by an inappropriate immune response to dietary gluten proteins. the aim of this study was to assess the prevalence of cd in our endoscopy unit by taking routine duodenal biopsies during upper gi endoscopy. materials andmethods: nine hundred and thirteen pati...

research advances during recent years offer new insight into therapy and the prevention of gastrointestinal ulcers by using medicinal plants. flavonoids, tannins, triterpenoids, fatty acids and essential oils are among the most effective herbal constituents that have potential antiulcerogenic properties, and most of them could be found in zataria multiflora. z. multiflora is one of the indigeno...

The aim of the present study in the pig was to describe the biliary and pancreatic secretory component of the migrating myoelectric complex (MMC) during the interdigestive period and after feeding, and to examine the effects of the extracorporal diversion of biliary or pancreatic secretions on the MMC and on the cyclical variation of intraduodenal pH. In a first trial six pigs (50.6 +/- 1.6 kg)...

abstract annular pancreas (ap) is a rare congenital malformation resulting from failure of pancreas ventral anlage rotation with the duodenum. this leads to a ring of pancreatic tissue that envelops the duodenum. clinical manifestations of ap most commonly develop in infancy or early childhood but can present at any age. the diagnosis of ap, usually suggested by an upper gi series or abdominal ...
