The effects of peripheral venous and portal venous delivery of insulin by a closed-loop insulin infusion device (Biostator GCIIS) on postprandial hyperglycemia and rates of glucose appearance, disappearance, and clearance were compared in alloxan-diabetic dogs. The amounts of insulin required and the peripheral venous plasma insulin concentrations achieved were not different for the two routes of insulin administration. No statistically significant differences in postprandial hyperglycemia or patterns of glucose disposal were observed between the two routes of insulin delivery. These studies indicate that in terms of hepatic versus extrahepatic disposal of glucose, there appears to be no practical advantage of portal venous over peripheral venous administration of insulin when a closed-loop insulin infusion device is used.

UI MeSH Term Description Entries
D007275 Injections, Intravenous Injections made into a vein for therapeutic or experimental purposes. Intravenous Injections,Injection, Intravenous,Intravenous Injection
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).
