[Therapeutic procedure in acute ulcer hemorrhage after cadaver donor kidney transplants].

In 62 cadaver-donor-allograft recipients we observed 11 times gastrointestinal complications 7 times (11%) an ulcer or an erosion of the mucous membrane could be secured gastroscopically. The therapeutic remedy of choice seems to be the well-timed 2/3-resection after Billroth II, since a too long hesitation increases the number of complications, has a negative influence on the choice of the intervention and increases the lethality.

[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.

[Transplantation of isolated islets of Langerhans into the liver of diabetic dogs (author's transl)].

Isolated islets of Langerhans were transplanted through the portal vein in the liver of 8 diabetic dogs; In 4 dogs a homologous transplantation was performed and another group of four dogs received isolated islets from their sisters or brothers. In both groups, there was an immediate effect on the blood glucose level. After pancreatectomy and injection of Alloxan the blood glucose rose to between 350 and 420 mg per 100 ml and after islet implantation the blood glucose decreased between 80 to 160 mg per 100 ml. The iv GTT'S were after islet implantation clear better than in the diabetic control animals. These results could maintained in the recipients with homologues islets over a period of 6 to 8 weeks and in the other group of dogs over a period of 6 to 12 months. We were able to show, that the islet implantation in the liver of diabetic dogs did not disturb the microscopic architecture of the liver. No signs of portal hypertension, hepatic congestion and embolism were found.

[Correlations between human portal and peripheral venous insulin and proinsulin concentrations under glucose infusion].

In 8 female patients carbohydrate tolerance was proved by means of glucose infusion test 3 days after cholecystectomy. Parameters analyzed in portal and peripheral vein blood are compared with that of 47 healthy persons. All patients demonstrate a pathological carbohydrate tolerance after cholecystectomy, further characterized by an increased lipolysis, a paradoxical rise of HGH, a diminished insulin secretion during the early and increased IRI output in the second phase. There is a significant positive correlation between portal and peripheral vein IRI concentration despite the rising portalperipheral venous IRI difference with raised portal venous IRI concentration. Corresponding differences for proinsulin concentrations can be established in the early phase only. Relations existing between blood glucose and IRI are shown by multiple regression analysis. They suggest that the altitude of IRI concentration is determined by previous blood glucose concentration.
