Primary Outcome Measures:
  • phase insulin response and phase insulin response measured as incremental area under the curve from 0-10 minutes and incremental area under the curve from 10-45 minutes respectively after iv glucose [ Time Frame: 2 hours ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • maximal insulin response defined as mean insulin at time 47 and 49 minutes (2 and 4 minutes after infusion of L-Arginine) [ Time Frame: 2 hours ] [ Designated as safety issue: No ]
