Abstract:
Objective To study the effect of amylin on the secretion of glucagon and insulin in isolated rat islets. Methods The models of isolated rat islets were established by collagenase digestion and dextran gradient centrifugation. The influence of various concentrations of amylin on both glucagon and insulin secretion was studied. Results Various concentrations of glucose increased the insulin secretion and decreased the glucagon secretion.Compared with the control, islets exposed to amylin (10~ -10 to 10~ -5 mol/L) for 1 hour showed decreasing glucagon secretion as the glucose increased (0, 5.6 and 11.2 mmol/L) (P
