Plasma secretin and pancreatic bicarbonate response to exogenous secretin in man.
The dose response of duodenal bicarbonate production during synthetic porcine secretin infusions was studied in six healthy volunteers and related to plasma secretin immunoreactivity. Secretin was infused in each individual at four different doses from 0-1 to 2-7 CU/kg/h, each infusion lasting for 60 minutes. Mean maximal bicarbonate secretion was 33 +/- 4 mEq/h. The secretin plasma level for h...
متن کاملAction of secretin on pancreatic enzyme secretion in man. Studies on pure pancreatic juice.
The action of pure, natural secretin on the pancreatic secretion of enzymes was investigated in six patients with external transduodenal drainage of the main pancreatic duct performed after biliary tract surgery. Secretin infused for five successive 50 minute periods at increasing doses of 0.03, 0.1, 0.3, 0.9 and 2.7 clinical units (CU)/kg/h, produce a dose dependent increase in protein and lip...
متن کاملImplicit dose-response curves.
We develop tools from computational algebraic geometry for the study of steady state features of autonomous polynomial dynamical systems via elimination of variables. In particular, we obtain nontrivial bounds for the steady state concentration of a given species in biochemical reaction networks with mass-action kinetics. This species is understood as the output of the network and we thus bound...
متن کاملEffect of metiamide on the response to secretin and cholecystokinin in man.
The effects of intravenous metiamide on the pancreatic exocrine response to intravenous infusion of secretin plus cholecystokinin has been studied in eight patients with duodenal ulceration. The secretion of bicarbonate and water was not altered by metiamide. The secretion of enzymes was significantly less than control during infusion of metiamide. The differences between the pancreatic and gas...
متن کاملEffect of diazepam and hyoscine butylbromide on response to secretin and cholecystokinin-pancreozymin in man.
Ten subjects received secretin and cholecystokinin or, in duplicate tests, the two hormones together with either diazepam or diazepam plus hyoscine butylbromide in order to determine whether these drugs, which are often used during retrograde endoscopic cannulation of the pancreatic duct, affect pancreatic and biliary secretion in response to the hormones. Diazepam with hyoscine butylbromide re...
