to determine if nonadrenergic transmitters make an important contribution to sympathetic neural effects on basal pancreatic hormone secretion , we examined the effect of local sympathetic nerve stimulation ( sns ) on the output of immunoreactive insulin ( iri ) , immunoreactive glucagon ( irg ) , and somatostatin ( sli ) from the duodenal lobe of the pancreas in situ in halothane-anesthetized dogs , under conditions where the actions of the classical transmitter norepinephrine ( ne ) should be blocked by propranolol ( prop ) and yohimbine ( yo ) .
