To investigate further the "hyperglucagonaemia" of diabetes mellitus, the metabolic clearance rate (MCR) and acute disappearance time (t1/2) of unlabelled pancreatic glucagon were estimated in 9 normal subjects and 7 insulin-dependent diabetics, using a constant infusion technique. The mean MCR (+/-SE) was similar for both groups (control: 9.0 +/- 0.6; diabetics: 11.4 +/- 1.0 ml/kg/min). The MCR was not influenced by the concentration of glucagon at the time of plateau, and the exogenous hormone appeared to be handled similarly to endogenous glucagon. On the other hand, t1/2 calculated from the fractional decay rate of glucagon from plateau was significantly prolonged in the diabetics (t1/2 ..
