pubmed:abstractText |
Somatostatin was infused for 5-8 hr into five normal men and eleven normal, conscious dogs. This infusion resulted in a persistent decline in plasma glucagon (40-60%) and insulin (30-45%). Plasma gluccose fell 15-25% during the initial 1-2 hr, but subsequently rose to hyperglycemic levels (130-155 mg/100ml) by 3-6 hr, despite persistent hypoglucagonemia. Glucose production initially declined by 40-50%, but later rose to levels 15-20% above basal rates while peripheral glucose utilization fell to levels 20-30% below basal, thereby accounting for hyperglycemia. Infusion of exogenous insulin so as to restore plasma insulin to preinfusion values or cessation of the somatostatin infusion with restoration of endogenous insulin secretion resulted in a prompt reduction of plasma glucose to baseline values. Prevention of the initial somatostatin-induced hypoglycemic response by intravenous infusion of glucose failed to prevent the delayed hyperglycemia. We conclude that somatostatin caused only transient hypoglycemia in normal subjects and that hyperglycemia eventually developes as a consequence of insulin deficiency. These data indicate that basal glucagon secretion is not essential for the development of fasting hyperglycemia and support the conclusion that insulin deficiency rather than glucagon excess is the primary factor responsible for abnormal glucose homeostasis in the diabetic.
