...J.W. Konturek; S.J. Konturek; T. Pawlik; W. Domschke This study was designed to determine the role of nitric oxide in gallbladder (GB) contractions in men. The studies were performed in 10 young healthy male volunteers. GB emptying was examined by ultrasonography under basal conditions and after...

...Ryuichiro Sakata; Takato Ueno; Takuji Torimura; Michio Sata; Kyuichi Tanikawa Background/Aims : Little is known about the relationship of portal venous pressure to contractility and histological changes in the gallbladder. In this study, we investigated the relationship between portal hypertension...

... to the gallbladder wall of 6 dogs. No stones had been implanted, but transient shadows appeared simulating jumping stone fragments in the bladder. Echoes within the bladder lumen occurred in 3 dogs and were associated with hemorrhage into the lumen; in an additional ex vivo experiment, shock waves generated echoes...

... and pancreatic polypeptide (PP) were studied in relation to gastrointestinal motility and gallbladder dynamics in the interdigestive state in 7 healthy male volunteers. No changes in CCK concentration were found in relation to the migrating motor complex (MMC). In 3 subjects a slightly but insignificant elevated...

...B.C. Yegen; E. Tankurt; N. Gürmen; M. Bayram; S. Oktay; N.B. Ulusoy The effect of pirenzepine on cholecystokinin (CCK)-stimulated gallbladder contraction in man was compared with that of atropine. Following pretreatment with atropine, pirenzepine or physiological saline in a random order, 6 healthy...

...S. Janković; D. Beleslin Both human and guinea pig gallbladder strips were tonically contracted by supramaximal concentrations of histamine in vitro. Guinea pig gallbladder strips were also tonically contracted by potassium, with no spontaneous relaxation after 5 min. The amplitude...

...C. Messa; M.A. Maselli; A. Cavallini; M.L. Caruso; F. Pezzolla; A. Di Leoa This study was designed to investigate the relationship between estrogen and progesterone receptor levels and in vitro contractile response of gallbladder muscle strips to stimulation by carbachol and cholecystokinin...

Kloppenborg Since octreotide (SMS 201–995, Sandostatin; Sandoz Pharmaceuticals) is a potent inhibitor of pancreatic exocrine secretion and gallbladder contraction...

...) on gallbladder contraction, pancreatic enzyme output and plasma CCK concentrations determined by radioimmunoassay and bioassay. Gallbladder emptying and bilirubin output in response to the intraduodenal administration of a mixed liquid meal were completely inhibited by an intravenous infusion of loxiglumide (10...

...Wim P.M. Hopman; Jan B.M.J. Jansen; Gerd Rosenbusch; Cornells B.H.W. Lamers To determine the role of cholecystokinin and the cholinergic system in cephalic stimulation of gallbladder contraction and to compare the degree of gallbladder contraction by cephalic stimulation with postprandial...

...Yoshio Ishikawa; Toku Takahashi; Takehira Yamamura Adenosine-5’-triphosphate (ATP) produced the rapid relaxation followed by the contraction in the gallbladder strips from guinea pig. The contractile response to ATP was antagonized with theophylline, but not with apamin and atropine. The dose...

... deals with the effects on the gallbladder emptying and the pancreatic enzyme output. Intake of a hypertonic glucose solution induces rapid gallbladder emptying. After early peaks, both biliary and pancreatic enzyme outputs remain at a steady lower level to the end. Somatostatin, started 20 min before...

...Lucio Gullo; Luigi Bolondi; Patrizia Priori; Paolo Casanova; Giuseppe Labò We have studied the effect of atropine on cholecystokinin (CCK)-induced gallbladder contraction in 7 healthy volunteers by means of real-time ultrasonography. Two series of tests were carried out in random order...

...B.O. Schneeman; R.L. Lyman An in vitro rabbit gallbladder assay was used to demonstrate that almost 80 % of the CCK activity in the rat gut is found in the proximal third of the small intestine. Previous studies had shown that pancreatic enzyme secretion is controlled from this area...

...M. Vagne; V. Troitskaja The effects on gallbladder contraction of three structurally related peptides, secretin, glucagon and the vasoactive intestinal peptide (VIP) have been compared in urethane-anesthetized guinea pigs. Secretin and glucagon had no effect alone but augmented cholecystokinin (CCK...

...A.G.A. Cowie; June Sutor The mean osmolality of bile from the common bile duct is similar to that of bile obtained from the gallbladder of patients with non-functioning gallbladders, and both means are significantly lower than the mean of bile in functioning gallbladders. The mean viscosity of bile...

...J.S. Davison; S.
