Calcium-antagonistic effects on glucose response to glucagon in patients with non insulin-dependent diabetes mellitus and in normoglycemic subjects. 1981

S Röjdmark, and D E Andersson, and R Hed, and L Sundblad

The current study was performed in order to investigate whether verapamil would affect the glucose response to glucagon differently in patients with non insulin-dependent diabetes mellitus (NIDDM) compared with age-matched normoglycemic controls. For that purpose glucagon was injected intravenously on a background infusion of verapamil, and for comparison also on a background infusion of saline in these two groups. Verapamil was found to blunt the glucose response to glucagon in the patients with NIDDM, whereas it augmented the glucose response to glucagon in the controls. This discrepancy could not be explained on the basis of verapamil-induced changes in the release of insulin, since verapamil did not effect the serum responses to glucagon. However, it could reflect the differences in hepatic handling of glucose, which has been shown to prevail in patients with NIDDM compared with healthy controls.

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).

D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

D005934	Glucagon	A 29-amino acid pancreatic peptide derived from proglucagon which is also the precursor of intestinal GLUCAGON-LIKE PEPTIDES. Glucagon is secreted by PANCREATIC ALPHA CELLS and plays an important role in regulation of BLOOD GLUCOSE concentration, ketone metabolism, and several other biochemical and physiological processes.
