[Double test of insulin sensitivity in normal and obese subjects].
13 normal and 16 obese subjects have been chosen for a double insulin tolerance test: 0,02 U/Kg of insulin were administered i.v. with an interval of 60'. The glycemic curve of the normal subjects show an identical lay out after both pulses; on the contrary the obese subjects could be divided into two subgroups. In the first one the lowering glucose action can be compared after both pulses, while in the second one the first stimulus causes a weather lowering glucose action, than in the first group, which is furtherly reduced during the subsequent pulse. An insulin resistance in these subjects is thus stressed. In the obese subjects the NEFA have a higher concentration in both groups than in the normal ones, show a normal decrease, but a certain delay is observed in the rebound phase.
