Biosynthetic human insulin (BHI) was compared with highly purified human pancreatic and pork insulin with regard to its ability to bind to erythrocytes of normal and insulin-dependent diabetic subjects (type I diabetes). The binding affinity or capacity of erythrocyte from both normal and diabetic subjects were comparable for biosynthetic and pancreatic(More)
1. The metabolism of protein and phospholipid in rat liver plasma membranes isolated by the method of Neville [(1960) J. Biophys. Biochem. Cytol. 8, 413-422] was investigated 3 and 6 h after the injection of D-galactosamine in vivo. During this time, all the biochemical and morphological alterations associated with hepatitis developed. 2. After the(More)
Gliquidone (a second generation sulphonylurea) was administered orally to normal rats 1 h before killing. Gliquidone treatment led to a decrease in plasma glucose, an increase in insulin and a diminution in glucagon concentration. Insulin binding to liver plasma membranes was enhanced by 40% in comparison with controls, whereas glucagon binding was slightly(More)
Rhinomanometry is today a routine method that may be used in private specialist practice, if X-Y recording is used. The results become clinical statements only when directly compared with mirror findings, i.e. by functional analysis of structure or when physiological variance is taken into account by reagibility tests. In those cases this elegant technique(More)
The Schwabing Insulin Prophylaxis Trial is a randomised, controlled pilot study designed to examine whether insulin therapy can delay or prevent the clinical onset of Type I diabetes in high risk first degree relatives of people with the disease. First degree relatives of patients with Type I diabetes, who were aged 4 years or more, had an islet cell(More)
The insulin receptor is associated with a protein kinase activity. This has been shown for the receptor of liver, fat, and some other tissues which are not primary targets of insulin action. Here kinase activity is demonstrated for the insulin receptor of rat skeletal and cardiac muscle with similar characteristics. Insulin (10(-7) mol/l) stimulates(More)
Six to 12 h after IP injection of 400 mg/kg of D-galactosamine in rats a 5-fold increase in plasma insulin was observed. In addition, impaired glucose assimilation was present after an IV load in spite of unchanged fasting glucose levels. In streptozotocin-diabetic rats (100 mg/kg IV) plasma insulin remained diminished 12 h after induction of(More)
In view of controversial findings regarding the mechanism for the increased intracellular hepatic cyclic 3′:5′ adenosine monophosphate levels in diabetic rats, we studied the dose-response relationship of the adenylate cyclase to glucagon stimulation in severely diabetic and in diabetic, insulin-treated rats. An enhanced response to glucagon and an(More)
