Diphasic Glucagon Release Induced by Arginine in the Perfused Rat Pancreas

Abstract

A DIPHASIC pattern has been recorded for insulin release after glucose stimulation in rat pancreas1 and in man2, and also after arginine stimulation in man3: this led to the concept of a two-compartmental storage system for insulin1. A diphasic pattern of secretion might be expected in some other endocrine cell types. To check this possibility for alpha-2 cells, perfused rat pancreas was submitted to both continuous infusion and pulses of a demonstrated glucagon stimulator, arginine4; glucagon responses were then measured.
