The sera of 59 patients with Crohn's disease (CD) and of 46 patients with ulcerative colitis (UC) were tested for autoantibodies (Aab) by indirect immunofluorescence with modern histochemical techniques using 19 different human tissues as antigenic substrates. Control collectives consisted of 19 patients with coeliac disease and of 100 healthy subjects. It(More)
15 normal individuals received twice at intervals of 60 min 1 Ivy dog U/kg body weight cholecystokinin (CCK) combined with 1 CHR U/kg secretin (Boots) intravenously. The volume and the bicarbonate secretion of the pancreas were almost identical following the initial and repeated injection. The secretion of bilirubin and enzymes were decreased after the(More)
It was demonstrated by indirect immunofluorescence that Crohn's disease and ulcerative colitis are serologically distinct. In 59 patients with Crohn's disease, confirmed by endoscopy and histology, 23 (39%) had serum autoantibodies against exocrine pancreas; in 17 (29%) the titre was 1 : 100 or higher. In 46 patients with confirmed ulcerative colitis(More)
The exocrine pancreatic secretion of water, bicarbonate, amylase, trypsin, chymotrypsin, and lipase and the plasma concentration of immunoreactive secretin (IRS) were studied before and after repeated intraduodenal infusions of cattle bile in man. After endoscopic cannulation of the main pancreatic duct, juice was collected in 5-min samples for 20 min. A(More)
The use of multivariate nonlinear discriminant analysis raised the rate of correct classification for 585 pancreatic function tests from 84 percent by the doctor to 93 percent by computer analysis. In addition to the "normal" and "pancreatic" disease groups, a group of 388 patients was found in whom secretion levels were neither normal nor typical of(More)
Fecal chymotrypsin (CT) activities were determined in 149 randomly collected fecal specimens of 80 patients in whom the pancreatic function had been tested by a secretin-cholecystokinin test. There was a significant correlation between fecal CT activities and outputs of trypsin (r = 0.3451, p less than 0.01) and amylase (r = 0.3285, p less than 0.01) in(More)
