Abstract

Pancreatic blood flow (PBF) and islet blood flow (IBF) have been determined separately in two different regions of the rat pancreas, namely, that perfused by the superior mesenteric artery (SMA) and that perfused by the coeliac artery (CA). Although there were no differences in either the PBF or the IBF between these two regions, the IBF, when expressed as a percentage of PBF, was significantly higher in the region perfused by the SMA. It is concluded that glucose regulation of the blood flow to the islets and exocrine parenchyma is similar in the two regions perfused by SMA and CA. In the SMA region the percentage of blood supply to the islets, in relation to the acinar part, is, however, somewhat higher than in that of the CA region.

摘要

已分别测定大鼠胰腺两个不同区域的胰腺血流量（PBF）和胰岛血流量（IBF），即由肠系膜上动脉（SMA）灌注的区域和由腹腔动脉（CA）灌注的区域。尽管这两个区域的PBF或IBF均无差异，但以PBF的百分比表示时，SMA灌注区域的IBF显著更高。结论是，在由SMA和CA灌注的两个区域中，葡萄糖对胰岛和外分泌实质血流的调节相似。然而，在SMA区域，相对于腺泡部分，胰岛的血液供应百分比略高于CA区域。
