Pancreatic, gallbladder, and intestinal responses to intraluminal magnesium salts in man

The results suggest that magnesium ion in the duodenum is a relatively weak stimulus to the pancreas and gallbladder, an action not augmented by the concomitant presence of the sulfate ion.

Calcium stimulation of gastrin and gastric acid secretion: effect of small doses of calcium carbonate.

It is suggested that the action of calcium on gastric secretion is partly mediated by gastrin, and the increase in serum gastrin and gastric acid output after intragastric calcium carbonate was not affected, however, by a simultaneous intraduodenal acid load.

Effects of graded amounts of intragastric calcium on acid secretion, gastrin release, and gastric emptying in normal and duodenal ulcer subjects

Assessment of effects of graded concentrations of intragastric calcium on acid secretion, residual gastric volume, and serum gastrin and calcium levels found that acid secretion was significantly increased above control values and by the three highest CaCl2 concentrations in ulcer subjects.

Different gastric, pancreatic, and biliary responses to solid-liquid or homogenized meals

It is suggested that gastric, pancreatic, and biliary responses to liquid test meals introduced into the stomach may differ substantially from the presumably more physiological response to ordinary solid-liquid meals.

Plasma concentration of secretin and gastric secretion following intraduodenal calcium infusion in man.

The aim of the present study was to test whether the previously demonstrated release of immunoreactive plasma secretin following intraduodenal bile infusion could be mediated by the calcium content of the bile, and to measure the serum concentrations of gastrin, calcitonin, and parathyroid hormone.

Intraluminal calcium binding does not mediate fatty acid-induced pancreatic bicarbonate secretion

It is suggested that calcium binding is not involved in mediation of fatty acid-induced pancreatic bicarbonate secretion because similar mechanisms of action may be involved.

Exocrine pancreatic secretion and immunoreactive secretin release after repeated intraduodenal infusions of bile in man.

The increase in the plasma concentration of secretin after repeated bile infusions, with a corresponding effect on flow rate and bicarbonate secretion, indicates that secretin may be the main factor responsible for the exocrine pancreatic secretion caused by intraduodenal bile Infusions.

Under physiological conditions it is probably the interplay of neural and hormonal mechanisms which regulates the pancreatic response to these stimulants.



Interactions between intraluminal bile acids and digestive products on pancreatic and gallbladder function.

Inhibition of CCK-PZ secretion by bile acid may contribute to the regulation of pancreatic and gallbladder function during digestion by reducing pancreatic enzyme secretion and permitting the gallbladders to refill after evacuation of its contents.

Pancreozymin bioassay in man based on pancreatic enzyme secretion: potency of specific amino acids and other digestive products.

The ability of products of digestion to stimulate pancreozymin secretion in man was investigated using a bioassay procedure, based on duodenal perfusion, which quantified the total outputs of

The effect of calcium and other salts upon the release of glucagon-like immunoreactivity from the gut.

Results are not incompatible with the concept that glucagon-like polypeptides are released from the gut during the absorption of certain salts, possibly to alert appropriate homeostatic regulators so as to avoid major changes in electrolyte concentration after the ingestion of large salt loads.

The three standard multivariate methods, PCA (Principal Component Analysis), Factor Analysis, and CCA (Canonical Correlations Analysis) will be reviewed and their connection with divergence minimization discussed.
