Serum insulin and glucose were measured in young male rabbits after a single intraperitoneal dose of 1 or 50 micrograms/kg of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Serum insulin levels in the high dosed rabbits were significantly decreased between 15 min and 8 h post treatment, equivalent after 24 h, significantly elevated 48 h post treatment, and they were not different at 10 days post-treatment when compared to weight matched and pair-fed controls. At the low dose, rabbits showed no differences in serum insulin from controls. In the high dose group, serum glucose levels were generally not different between treated and control animals, though there was a transient hyperglycemia 1 h after treatment, and both treated groups became hypoglycemic after ten days. The results indicate that TCDD altered serum insulin levels which were not coupled to changes in serum glucose.

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).
