The relationship between the dose of intravenously administered streptozotocin (a N-nitroso derivative of glucosamine) and the diabetogenic response has been explored by use of the following indices of diabetogenic action: serum glucose, urine volume, and glycosuria, ketonuria, serum immunoreactive insulin (IRI), and pancreatic IRI content. Diabetogenic(More)
The aim of our study was to measure the gastric emptying rate for a solid meal in diabetic patients who had no gastrointestinal complaints with (group 1, n = 12) or without (group 2, n = 10) cardiac autonomic neuropathy and in normal controls comparable in age and sex (group 3, n = 10). Gastric emptying rate was assessed with a sequential scintiscanning(More)
We studied the effects of perindopril, an angiotensin converting enzyme (ACE) inhibitor administered during 12 months, on creatinine clearance, albuminuria and glycaemic control in diabetic subjects with mild to moderate hypertension. After 1 month placebo, 40 insulin-treated patients were divided into 3 groups based upon their urinary albumin excretion(More)
The nature and origin of proteinuria in diabetes mellitus have been investigated by measuring the urinary excretion of seven specific proteins of low (beta 2-microglobin, retinol-binding protein) or high molecular weight (albumin, transferrin, hemopexin and IgG). Using the Alcian Blue binding test, we also measured negative charges on red blood cell (RBC)(More)
Cobalt (Co'++) inhibited glucose-, leucine-, and K'+-induced immunoreactive insulin (IRI)release by isolated rat islets. This inhibition of the insulinotropic effect of glucose was dose dependent, affected both phases of secretion, was very rapid, and was well reversible. It exhibited a kinetics similiar to that of Ca'++ omission, and the metal (2.5 mM)(More)
