we examined the response of plasma glucose concentration and glucose counterregulatory factors ( eg , glucagon , epinephrine , growth hormone , cortisol , and norepinephrine ) to insulin-induced hypoglycemia in four patients with shy-drager syndrome and in five control subjects to determine if glucose counterregulation occurred in the patients with sympathetic and parasympathetic nervous system defects .
