Arms of the Study
Arm 1
Arm 2
Arm Type
Experimental
Experimental
Arm Label
GLP-1
Saline
Arm Description
A graded glucose infusion with an infusion of GLP-1 (1½ pmol/kg/min)
A graded glucose infusion together with a continuous infusion of saline
Outcomes
Primary Outcome Measures
insulin secretion rate (ISR) were derived by deconvolution of c-peptide. ISR is expressed as pmol/kg/min
Secondary Outcome Measures
The calculated ISR values was plotted against the ambient plasma glucose. The slopes of this linear relationships were calculated by cross-correlation analysis and is and estimation of beta-cell responsiveness (pmol/kg/min)/mmol/l

5. Study Description
Brief Summary
The ability of glucagon-like peptide 1 to enhance beta-cell responsiveness to I.v. glucose is impaired in patients with type 2 diabetes mellitus compared with healthy individuals. We investigated whether 4 weeks of near-normalisation og blood glucose improves the potentiation of glucose-stimulated insulin secretion by GLP-1
