Popis: Arginine vasopressin, oxytocin and ACTH are released from the pituitary gland in response to acute hypoglycemia. To investigate the role of α-adrenergic mechanisms in mediating this response, 6 non-diabetic subjects were studied during hypoglycemia induced by 0.15 IU/kg iv insulin under control conditions, and during non-selective α-adrenergic blockade with phentolamine. In the control study plasma arginine vasopressin rose from 1.6±0.8 pmol/l (mean ± sem) basally to a maximum of 2.5±0.8 pmol/l following hypoglycemia (p
