Summary
The initial plasma glucose concentration of unanesthetized calves with cut splanchnic nerves, given 2-deoxyglucose (1.2 mmoles/kg, i.v.), was either lowered by prior starvation, or raised by a continuous infusion of exogenous glucose. Raising the initial plasma glucose concentration completely suppressed the release of pancreatic glucagon and pancreatic polypeptide but substantially enhanced the release of insulin in response to 2-deoxyglucose.
