Pancreatic blood flow in conscious dogs after oral administration of glucose

Dogs with an electromagnetic flowprobe implanted around the superior pancreaticoduodenal artery and with an hydraulic occluder implanted upstream from the flowprobe were examined between the 3rd and the 8th postoperative day. During an oral glucose load, blood flow increased from the beginning of administration to about 25 minutes, but not when blood glucose and plasma IRI exhibit their maxima. The rise of pancreatic blood flow is assumed to be produced by reflexes similar to those stimulating insulin secretion and exocrine pancreatic function during the early phase of an oral glucose load.
