The effect of glucose and Domperidon (R 33812, pharmaceutical factory Gedeon Richter, Budapest) on the insulin secretion were investigated in the isolated islets of Langerhans of rats. The insulin secretion was increased by glucose and also by Domperidon, however, in a smaller size. The insulin secretion of cryopreserved islets--stored in liquid nitrogen of -196 degrees C during 2-6 months--was equal with the secretion of fresh isolated islets. Thus the cryopreservation had not impaired the insulin secretion ability of the islets.

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).

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.
