ABSTRACT In a previous paper it was shown that 15 out of 85 healthy subjects with a normal intravenous glucose tolerance demonstrated a low plasma insulin response to glucose infusion which was similar to that obtained in diabetic subjects. In the present paper it has been shown that the type of insulin response to glucose infusion was the same when the test was repeated. Low insulin responders to glucose infusion, as a group, also showed low insulin response to intravenous tolbutamide and oral glucose. This indicates that the type of insulin response is characteristic for a given subject irrespective of the stimulation used. There seemed to be no difference in the occurrence of diabetes in the family history of the groups of low and high insulin responders.

ABSTRACT The insulin response during a standardized glucose infusion (GIT) was studied in a group of 13 monozygotic twin pairs previously registered as consisting of one diabetic/one non-diabetic member. At the time of the study three of the non-diabetic subjects had developed overt diabetes and three decreased glucose tolerance only. Of the non-diabetic members all but one (with diabetes due possibly to chronic pancreatitis in the sibling) showed an insulin response similar to that seen in diabetic subjects, and in healthy subjects previously assumed to be potential diabetics. The present study therefore supports our earlier suggestion that a low insulin response characterizes potential diabetes. There was a striking similarity between the insulin curves in the twin pairs, irrespective whether diabetes occurred in one, in both or in none of the members. It is suggested as a working hypothesis that the type of insulin response to glucose infusion is genetically determined, and that a low insulin response is a prerequisite for the development of diabetes mellitus.

Plasma glucose clearance rates were lower (P < 0.10) in wethers fed the high potassium (0.32% Mg-4.90% K) diet compared with those of the control (0.32% Mg-0.75% K). Insulin responses to glucose infusion and feeding tended to be reduced in wethers fed the high potassium diet as compared to the control. Key words: Sheep, high potassium diet, glucose utilization, insulin

An analogue computer model has been constructed for the analysis of the interrelationship between blood glucose and plasma insulin concentrations during glucose infusion. The model presented gives quantitative information on the effect of plasma insulin on glucose uptake, the total amount of glucose taken up by the tissues at a given time, the effect of blood glucose on the release of stored and newly formed insulin, and the rapidity by which plasma insulin is increased in response to hyperglycaemia. Such an analogue computer model might be a useful tool in the investigation of the various dynamic factors involved in the glucose- insulin interrelationship.

ABSTRACT Plasma insulin response to glucose infusion was found to be markedly increased in 20 patients with active acromegaly and with normal intravenous glucose tolerance. The insulin response was more pronounced in patients with highly active acromegaly than in those showing moderately active disease. In five patients with active acromegaly and with decreased glucose tolerance the insulin response was delayed and smaller than normal, i. e. similar to that seen in diabetic subjects without acromegaly. After successful treatment of the acromegaly insulin response to glucose infusion was normalized in the patients with normal glucose tolerance. In those with decreased glucose tolerance the diabetic type of insulin response remained unchanged even when the glucose tolerance was normalized. It is suggested that diabetes in connection with acromegaly develops only in prediabetic individuals, i.e. subjects with decreased insulin response to hyperglycaemia, who are unable to overcome the diabetogenic effect of growth hormone by compensatory hyperinsulinism.
