Pancreatic secretion of enzymes and gallbladder contraction in response to intestinal stimulants are thought to be mediated through the vagus nerve and by means of release of cholecystokinin (CCK). The effect of truncal vagotomy on the release of CCK, pancreatic protein secretion, and gallbladder pressure (all stimulated by intraduodenal instillation of oleate) was studied in five dogs. Each do...
Previous models have attributed changes in respiratory modulation of pontine neurons after vagotomy to a loss of pulmonary stretch receptor "gating" of an efference copy of inspiratory drive. Recently, our group confirmed that pontine neurons change firing patterns and become more respiratory modulated after vagotomy, although average peak and mean firing rates of the sample did not increase (D...
The effect of intraduodenal infusion of hypertonic saline and glucose on pentagastrin-stimulated gastric secretion was investigated in 35 normal subjects, 32 duodenal ulcer patients and 32 patients after truncal vagotomy and pyloroplasty. A significant gastric inhibitory response occurred after 0.51 M saline and 1-03 M glucose in the normal subjects and duodenal ulcer patients but after vagotom...
The value of insulin and augmented histamine tests in predicting recurrence of duodenal ulcer within six to eight years after truncal vagotomy and drainage was assessed in a series of 500 consecutively and electively operated patients. Criteria of recurrence were established by a discriminative analysis of gastric acid secretion parameters. Recurrence was predicted with a probability of about 7...
The occurence of anemia following partial gastrectomy is well recognised: the reported incidence ranges from three to 63 per cent'. Iron deficiency is the commonest cause of the anaemia, deficiencies of either B12 or folic acid accounting for only a small number1. With the advent of vagotomy and drainage as the routine treatment for duodenal ulcer it was hoped that anaemia would no longer be a ...
A group of 133 patients treated for bleeding peptic ulcer in our Department, is reviewed. Within several hours of admission, all patients underwent upper gastrointestinal tract gastroscopy and obliteration of the bleeding ulcer. Bleeding gastric ulcers were found in 41 patients, and duodenal ulcers in 92 patients. Patients were classified according to the Forrest scale: IA - 11 patients, IB - 4...
Taurocholate prevents the loss of intrahepatic bile ducts due to vagotomy in bile duct-ligated rats.
The aim of this study was to determine whether taurocholate prevents vagotomy-induced cholangiocyte apoptosis. After bile duct ligation (BDL) + vagotomy, rats were fed taurocholate for 1 wk in the absence or presence of wortmannin. Caspase involvement was evaluated by measurement of caspase 8, 9, and 3 activities. Proliferation was determined by morphometry and PCNA immunoblots. Changes in phos...
