متن کاملCalcium and Diacylglycerol I " Secretion
/vleasurements of intracellular Ca / + in adrenal medullary cells suggest that a transient rise in Ca z + leads to a transient secretory response, the rise in Ca 2 § being brought about by an influx through voltage-sensitive Ca channels which subsequently ir~activate. The level of Ca 2 § observed is much smaller than the Ca 2 + needed to trigger secretion when introduced directly into the cell....
متن کاملCalcium, carbonic anhydrase and gastric acid secretion.
Previous data concerning the action of calcium (Ca) on gastric acid secretion (GAS) indicated that calcium ions increase GAS elicited by gastrin released through a vagal mechanism, and also by a direct effect on parietal cells. Our research showed that the stimulating effect of calcium on gastric acid secretion can be antagonized by verapamil administration, which reduces gastric acid secretion...
متن کاملRole of Calcium in Glucagon Secretion
The role of calcium ions in the process by which nutrients affect glucagon secretion by pancreatic islet α-cells remains the matter of an apparently endless debate. In the prolongation of recent articles dealing with this matter, the present review draws attention to the dual role of Ca2+ as revealed by prior publications. In such a perspective, emphasis is placed on the increase in glucagon ou...
متن کاملExocrine pancreatic enzyme and calcium secretion in health and pancreatitis.
Calcium, enzyme, and total protein secretion were measured in secretin stimulated pancreatic juice in health, "early" chronic pancreatitis, and in chronic calcific pancreatitis. Increased concentrations of trypsin, total protein, and calcium, and increased outputs of calcium and protein were shown to be present in the "early" stages of the disease, indicating that an environment conducive to th...
