[Upper gastrointestinal tract hemorrhages following heart surgery].

The clinical histories of 612 patients who underwent an operation of the heart were evaluated. Eight times a more severe haemorrhage from the upper gastrointestinal tract was described, i.e. 1.3%. One patient died under the signs of the septic shock. All patients were treated conservatively, only in one patient an ulcer existed 12 years before the heart operation.

[A prophylactic regimen for infections in colorectal surgery (author's transl)].

Without special prophylaxis, surgery of the colon and rectum is likely to result in postoperative complications due to infection at a percentage of 30 to 50. Prophylaxis against infections in colonic operations covers preoperative influence on general body defence, a subtle operating technique and special preparation of the intestine, the latter including adequate bulkage - free diet, a special preparation of the intestine and preoperative administration of antibiotics. Preparation by means of phthalylsulfathiazol has shown no effects. A preparation programme is suggested for 3 to 8 days preoperatively.

[Characteristics of pancreatic basal secretion in the dog].

A method is described for the simultaneous evaluation of the pancreatic, the biliary and the gastric secretion in long-term experiments. Under these conditions, the pancreatic basal secretion is characterized. The pancreatic basal secretion is a very variable reference value that is influenced by endogenous stimuli. The upper threshold value for the secretion rate was 2.2 ml/15 min. Under the influence of spontaneous biliary secretion, the protein concentration amounts to a characteristic value of relatively unimportant variance. If the pancreatic basal secretion is used as a reference value, the spontaneous secretions of the biliary ducts (gastrin release from the duodenum?) and of the stomach (secretin release from the duodenum) and be taken into account. A further disturbing factor interfering with both the pancreatic and the gastric basal secretion is to be neglected.

[Vagotomy and exocrine pancreatic secretion (author's transl)].

In dogs supplied with chronic pancreatic fistulas, there is no change of the basal exocrine secretion of volume three weeks after a bilateral truncular vagotomy. The normal initial reflex secretion during meal ingestion or glucose loading are abolished. On the whole, the secretory activity is reduced by about 50% after feeding. Secretions of volume and of enzyme protein are inhibited to the same extent, but that of bicarbonate is more strongly influenced. After vagotomy the inhibitory influence on all secretions of a rabidly produced hyperglycemia is reinforced. In pancreatic juice there is immunocreactive insulin activity (less than 1% fo the daily secreted amount). Insulin secreted in pancreatic juice after feeding is strongly reduced after vagotomy. This is the best reproducible proof of an influence on the exocrine pancreatic function of vagotomy.

The effect of meal feeding and of sham-feeding on insulin secretion in dogs.

After feeding intact conscious dogs 1000 g mashed meat, peripheral venous immunoreactive insulin activity (IRI) increases before any enhancement of amino nitrogen concentration. This course of IRI is paralleled by a decrease of free fatty acids. Meal feeding in dogs, whose pancreatic juice is completely diverted from the gut by a fistula, is followed by a similar IRI increase without a distinct enhancement of amino nitrogen. In oesophagus fistula dogs, sham-feeding meat in 9 out of 15 experiments results in a considerable early IRI increase which is correlated with a small but a significant decrease of blood glucose and free fatty acid concentrations. In these tests there was no amino nitrogen alteration either.
