We studied the effects of two insulin mixtures on glucose levels and plasma free insulin in 12 type I diabetic patients previously rendered normoglycaemic using an artificial pancreas (Biostator). Mixture Iwas made with 24.5 +/- 1.7 I.U. of isophane protamine insulin (Insulatard Nordisk), mixed with 9.8 +/- 0.78 I.U. of short-acting soluble insulin (velosulin Nordisk). Mixture II consisted of identical doses of an insulin zinc suspension (Monotard Novo) with soluble insulin (Actrapid Novo). 30 minutes after injection, all patients had a standard breakfast and blood samples for glycaemia and insulinemia were taken for the next 6 hours. Plasma glucose levels were significantly lower after the injection of mixture I at 30 and 180 minutes (p 0.01) and at 45, 60, 75, 90, 105, 150, 210 and 240 minutes (p 0.05). Free insulin levels were higher after mixture I, although no statistically significant difference was found at any point. We conclude that mixing insulin zinc suspensions in the same syringe with soluble insulin results in an impairment of the quick action of the soluble component.

UI	MeSH Term	Description	Entries
D007328	Insulin	A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

D007336	Insulin, Isophane	An intermediate-acting INSULIN preparation with onset time of 2 hours and duration of 24 hours. It is produced by crystallizing ZINC-insulin-PROTAMINES at neutral pH 7. Thus it is called neutral protamine Hagedorn for inventor Hans Christian Hagedorn.

D003922	Diabetes Mellitus, Type 1	A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
