Abstract
Chronic treatment of rats with triiodothyronine (T3) resulted in suppression of insulin release from the isolated pancreas when perfused with 8.6 mM glucose. This inhibition could be partially overcome by 16 mM glucose but the insulin release was still significantly reduced. Arginine and gastric inhibitory polypeptide (GIP) induced an insulinotropic action in both control and T3-treated preparations. This was achieved in the latter, in the absence of a second phase of insulin secretion to glucose. The insulinotropic effect of both arginine and GIP was abolished by mannoheptulose in both control and T3-treated animals.This publication has 1 reference indexed in Scilit:
