[Study of the correlation of sonographic and scintigraphic results in measuring stomach emptying].

"Stomach cockade" can be readily imaged sonographically, so that it has also been possible to carry out studies of gastric motility or measurements of gastric emptying times of fluids. However, the results of measurements should be verified by reference methods using new investigation techniques. For this reason, we measured synchronously by sonography and scintigraphy the emptying of test fluids from the stomach in patients with diabetes mellitus and suspected gastroparesis.

The treatment of chronic recurrent pancreatitis with depot secretin--a preliminary report.

Increased viscosity and raised lactoferrin, trypsin and protein concentrations in selectively aspirated pancreatic secretion, prompted us to try depot secretin therapy in patients with advanced chronic recurrent pancreatitis without pancreatic duct obstruction or pancreatic pseudocysts. The idea behind this approach was that it might "wash out" the sticky, protease-rich secretion. In a randomized double-blind trial we administered depot secretin at doses of 800 CU by subcutaneous injection twice daily for 7 days.

[Sonography of gallbladder kinetics during cholagogue therapy].

Sonography of gallbladder kinetics shows that a cholagogue exercising a spasmolytic action counteracts the periodic voiding of the gallbladder or even induces an increase in volume of the gallbladder in healthy persons and in patients with cholecystolithiasis. This effect cannot be seen in chronic cholecystitis.

[Effect of secretin and gabexate-mesilate (synthetic protease inhibitor) on serum amylase level after ERCP].

Complication rate of ERCP is about 2%, mortality rate 0,2%. In about 1% acute pancreatitis or recurrency of chronic pancreatitis occurs. In 20 to 73% a rise of serum amylase is noted without clinical symptoms.

[Ultrasound measurement of gastric emptying time values].

Sonography, as a non-invasive procedure, may be used also for studying the gastric emptying time. After 250 ml of a liquid test meal the gastric emptying time was determined in 20 subjects. In each subject the applied test meal could be traced in the prepyloric antrum.

[Influence of various non-steroid antirheumatic drugs on the electric potential between the gastric serosa and mucosa (author's transl)].

Non-steroid antirheumatic drugs inhibit the synthesis of prostaglandin, which results in a reduction in the efficacy of the gastric mucosal barrier. The transmural electric potential difference of the stomach wall would appear to be a useful criterion for mucosal barrier function. After 4 weeks of treatment with Indomethacin, Azapropazpone, Diclofenac or Phenylbutazone, a significant reduction in the gastric potential difference as compared with the pre-treatment measurement was observed.

Gastroscopic findings after therapy with non-steroid antirheumatic drugs.

Non-steroid antirheumatic drugs inhibit synthesis of prostaglandins, which gives rise to a reduction in gastric mucosal perfusion and the limitation of cytoprotective factors. Thus, pan-endoscopic follow-up examinations performed after four weeks of treatment with various non-steroid antirheumatic agents also revealed a significantly increased incidence of erosions, ulcers and reflux oesophagitis. After therapy of at least 18 months with non-steroid antirheumatics, incomplete erosions were verified in 35% of the cases, complete erosions in 7.

Selectively aspirated pure pancreatic secretion. Viscosity, trypsin activity, protein concentration and lactoferrin content of pancreatic juice in chronic pancreatitis.

The viscosity, trypsin activity, protein concentration and lactoferrin concentration in selectively aspirated, pure pancreatic secretion uncontaminated by bile, were determined in 46 patients with chronic pancreatitis and compared with the values obtained in 39 control subjects. The viscosity was measured using a modified capillary viscosimeter, the trypsin activity and the protein concentration using photometry, and the concentration of lactoferrin employing a new standard. It was found that in chronic pancreatitis, viscosity, trypsin activity and lactoferrin concentration was also found to be increased, but the differences were not significant.

[Therapy of gastrointestinal disorders due to oral rheumatism therapy. Effect of bromopride on antirheumatic agent-induced functional reduction in the gastric mucosa barrier].

Non-steroid antirheumatic agents inhibit the synthesis of prostaglandins to an extent which depends upon their respective chemical composition. The result of this inhibition is a reduction in gastric mucosal perfusion, a limitation of cytoprotective factors, and an enhanced back diffusion of H+-ions into the mucosal cell. The function of the gastric mucosal barrier is restricted and a reduction in the measurable electric potential between the gastric serosa and mucosa ensues.

[Lactoferrin levels in pure pancreatic secretion of chronic pancreatitis (author's transl)].

As compared to 20 controls, 14 patients with chronic pancreatitis showed a significantly higher lactoferrin level in pure pancreatic secretion. The determination of lactoferrin levels in pure pancreatic secretion is an important parameter in the diagnosis of chronic pancreatitis.

[Chronic pancreatitis: diagnostic value of endoscopic retrograde pancreaticography, of pancreatic sonography, and of secretin-pancreozymin test corrected for volume losses (author's transl)].

Endoscopic retrograde pancreaticography (ERP) and secretin-pancreozymin test corrected for losses (SP test) were performed in 153 patients suspected to have pancreatic disorders in order to evaluate diagnostic significance of these procedures. Pancreatic sonography was done in addition in 110 of these patients. If pancreatic excretion was normal, ERP results turned out to be normal in the same patients as well.

[Viscosity of pure pancreatic juice in chronic pancreatitis (author's transl)].

In patients with chronic pancreatitis viscosity is significantly increasesed compared to controls when pure pancreatic juice aspirated in the course of duodenoscopy is analysed. This parameter may represent a simple method for the diagnosis of chronic pancreatitis.

Viscosity and trypsin activity of pure pancreatic juice in chronic pancreatitis.

In patients with chronic pancreatitis, the viscosity and trypsin activity of the pure pancreatic juice obtained endoscopically are significantly higher than in healthy subjects. These two parameters may thus represent a simple method for the diagnosis of chronic pancreatitis.

[Analysis of pancreatic function. Determination of fecal chymotrypsin and the secretin-pancreozymin test. Comparative study].

Fecal chymotrypsin determination and secretin-pancreozymin test with volume-loss corrected were carried out intra-individually on 57 clinically normal test subjects and 51 patients with chronic pancreatic disease. A good correlation could be established in every case between the chymotrypsin activity in stool and the chymotrypsin output in the duodenal aspirate. False-positive chymotrypsin activity was not to be found in healthy subjects.

The function of the exocrine pancreas after exogenous and endogenous stimulation in Billroth II patients.

Maldigestion phenomena in patients subjected to a Billroth II (B II) operation are in part attributed to an atrophy of the pancreas due to inactivity. In order to investigate this, a Lagerlöf tube was introduced under endoscopic control into the afferent loop, and the function of the exocrine pancreas studied after endogenous and exogenous stimulation. During endogenous stimulation of the exocrine pancreas by means of a Lundh test meal, no significant differences in the secretory pattern of the Billroth II patients as compared with healthy test subjects were found.

[The function of the hydrokinetic and ekbolic pancreas after acute pancreatitis].

Thirteen patients were investigated 3-4 weeks (I. examination) and 3-5 months (II. examination) after the ceasing of the signs symptoms of an acute pancreatitis concerning their hydrokinetic and ekbolic pancreas-functions.

Duodeno-gastric reflux in gastric ulcer patients in relation to intestinal metaplasia of the gastric mucosa.

Using vitamin B12 labelled with Co58 as an exogenous marker, and bilirubin as an endogenous marker, the duodeno-gastric reflux was determined quantitatively in 13 gastric ulcer patients under basal conditions and under stimulation (1 CU secretin/kg body weight + 1 CU pancreozymin/kg body weight) of the exocrine pancreas; in addition, a histological examination of the gastric mucosa was carried out by taking multiple biopsies from along the greater and lesser curvatures of the stomach. Altogether, a more marked mean duodeno-gastric reflux was found in the ulcer patients than in the 14 control subjects. If, however, the ulcer patients are differentiated in accordance with the results of the histological findings in the biopsy material, it is seen that an increased reflux is found only in those ulcer patients presenting with an intestinal metaplasia in the antrum.

Effects of 13-nle-motilin on salivary, gastric, and pancreatic secretions in man.

Salivary, gastric, and pancreatic secretory responses to intravenous 13-norleucine-motilin (13-nle-motilin), a synthetic analog of motilin and biologically equivalent to the natural polypeptide, were studied in healthy volunteers. 13-nle-Motilin in doses of 100 ng/kg body wt/hr significantly stimulated gastric pepsin output, while H + secretion and serum gastrin levels remained unchanged. Enhanced pepsin secretion was not accompanied by an increase in gastric secretion of cyclic 3', 5'-adenosine monophosphate, nor did gastric mucosal levels of the cyclic nucleotide rise.

[Carbohydrate administration and electrolyte balance in patients under intensive care].

A twenty-four percent solution of carbohydrates 0.2 g/kg/h consisting of fructose, xylit and glucose in a 2:1:1 ratio and an aminoacid solution 0.03 g/kg/h were given to 13 patients of the internal medicine intensive care unit.
