Normal values and upper limits (95th percentile) of liver, spleen, pancreas, and portal vein size were determined prospectively with ultrasound in 915 healthy subjects. Sex, age, weight, height, and body surface area were determined in each case. Since correlation of longitudinal and transverse organ diameters with physical data was poor (r less than or(More)
To determine the average diameter and the upper normal limit of the common bile duct in healthy man, 830 blood donors were examined by ultrasound. The mean diameter was 2.5 +/- 1.1 mm (SD) at the porta hepatis and 2.8 +/- 1.2 mm (SD) at the widest point, the regression coefficient between both diameters being r = 0.84. None of the healthy subjects had a(More)
In 10 normal subjects, in 32 patients with duodenal ulcer (DU), and in 11 patients with partial gastrectomy (Billroth I), serum gastrin rose significantly after an oral and intraduodenal test meal. The highest increases were observed in DU patients after the oral as well as after the intraduodenal test meal. After the intraduodenal test meal in 4 normal(More)
50 mg pirenzepine inhibit basal acid secretion by 39.9% and peptone-stimulated acid output by 21.3%. The percentage of inhibition is nearly doubled if the same dose is given after a treatment with 50 mg pirenzepine twice daily for 3 to 7 days. No acute effect on serum gastrin levels can be demonstrated by a single dose of pirenzepine. After pretreatment(More)
Atropine and an eightfold greater amount of pirenzepine inhibit pentagastrin-stimulated secretion to nearly the same extent (70-75%). Neither drug influences acid concentrations markedly (18%). Atropine and pirenzepine decrease the potassium concentration of gastric juice. By increasing electrical vagal stimulation the inhibitory effect of cimetidine(More)
Early treatment of acute hepatitis C infection with interferon alfa-2b (IFN-alpha-2b) prevents chronicity in almost all patients. So far, no data are available on the long-term outcome after interferon (IFN) therapy of acute hepatitis C. The aim of this study was to assess the clinical, virological, and immunological long-term outcome of 31 successfully(More)
