In order to determine whether glucagon levels of diabetic subjects are suppressible, alpha cell responsiveness to acute insulin administration (0.1 units/kg intravenously) was determined in fourteen juvenile onset, healthy diabetic and eight control subjects. In the diabetics, insulin produced a significant but slow fall in blood glucose over 60 min (P less than 0.01). On the other hand, glucagon levels fell dramatically in all diabetics to undetectable levels (P less than 0.001). Only one diabetic became hypoglycaemic and he alone showed a rebound rise of glucagon at 60 min. The rate of fall of blood glucose in the diabetic subjects was not influenced by the basal glucagon level (r=0.13) or..
