1. Eleven patients with type II diabetes mellitus were studied prior to, and after short- (10 days) and long-term (6 months) glibenclamide treatment. 2. A marked decrease in glucose level was observed after short- and long-term therapy using the oral glucose tolerance test (OGTT) and diet test (DT). 3. After short-term therapy, insulin level increased by 52.5% with the OGTT and by 37.6% with the DT; after long-term therapy, the increases were 78.6% and 69.5%, respectively. 4. Insulin binding to erythrocytes was unchanged by short- or long-term glibenclamide therapy. 5. These data suggest that the hypoglycemic effect of glibenclamide results from an increase in insulin secretion and that extrapancreatic actions at the receptor or post-receptor level are not necessarily involved.

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).

D011972 Receptor, Insulin A cell surface receptor for INSULIN. It comprises a tetramer of two alpha and two beta subunits which are derived from cleavage of a single precursor protein. The receptor contains an intrinsic TYROSINE KINASE domain that is located within the beta subunit. Activation of the receptor by INSULIN results in numerous metabolic changes including increased uptake of GLUCOSE into the liver, muscle, and ADIPOSE TISSUE.

D003924 Diabetes Mellitus, Type 2 A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
