Effect of somatostatin on neurotensin-induced glucagon release and hyperglycemia
M Ukai, I Inoue and T Itatsu
Administration of neurotensin to dogs resulted in rises in circulating
blood glucose, glucagon and insulin levels, the rise in glucagon being more
pronounced than that in insulin. Infusion of somatostatin along with
neurotensin suppressed glucagon and insulin responses to neurotensin and
prevented the rise in blood glucose levels. These results suggest that the
hyperglycemia seen after neurotensin is due to neurotensin stimulation of
glucagon release over insulin release.
