| Abstract: | Our experiments were carried out on the isolated perfused rat pancreas. The effect of extracellular ATP (8 microM) on insulin secretion induced by tolbutamide (0.04 mM) was studied in the presence of substimulating glucose concentration 4.2 mM (0.75 g/l). ATP (8 microM), ineffective per se at this concentration, highly potentiated the insulin secretion induced by tolbutamide (0.04 mM). |
