摘要: The aim of this study was to measure the role duodenal loop in biliopancreatic secretion man by infusing various stimuli at ampulla Vater and collecting contents ligament Treitz, above an occluding balloon. Perfusion 10 ml/min a first mixture aminoacids - phenylalanine (47.2 mmol), methionine (38.2 tryptophan (11 valine (61.6 mmol) increased cholecystokinin (CCK) plasma concentrations bile salt output (p less than 0.005) as compared with control electrolyte solution, but did not change pancreatic enzyme significantly; infusion another aminoacid arginine (32.4 histidine (14.1 leucine (36 isoleucine (21.5 lysine (31 threonine (23 CCK concentrations, or output. respective distension endogenous investigated perfusing solution 2, 5, ml/min. Changing perfusion rate from 2 5 led significant increase 0.01) no further Bile influenced solution. During despite stepwise release, only lipase 0.05) when raised Our results suggest that release (1) depends on nature (2) has predominant regulation low is effective superimposed mechanical stimulus caused (3) major for gall bladder contraction which distension.
