Insulin responses to mixed meals: comparison of an artificial beta cell and normal beta cells. 1979

D L Horwitz

The peripheral glucose and free insulin levels seen following a mixed meal in six insulin-dependent diabetic patients whose insulin was administered by a glucose-controlled insulin infusion system (GCIIS) were compared to those of normal subjects who received the same mixed meal or who were given separately carbohydrate, protein, or fat in amounts equivalent to those contained in the mixed meal. Patients treated with the GCIIS achieved nearly normal glucose levels immediately after the mixed meal, but this was accompanied by marked hyperinsulinemia. In the period from 120 to 240 minutes after the start of the mixed meal, the GCIIS duplicates the insulin levels produced by the normal pancreas after a glucose meal and, with appropriate algorithm constants, closely approximates those seen after a mixed meal.

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).

D007515	Islets of Langerhans	Irregular microscopic structures consisting of cords of endocrine cells that are scattered throughout the PANCREAS among the exocrine acini. Each islet is surrounded by connective tissue fibers and penetrated by a network of capillaries. There are four major cell types. The most abundant beta cells (50-80%) secrete INSULIN. Alpha cells (5-20%) secrete GLUCAGON. PP cells (10-35%) secrete PANCREATIC POLYPEPTIDE. Delta cells (~5%) secrete SOMATOSTATIN.
