作者用6条狗的胰十二指肠标本作体外血液灌注,研究在基础条件下和用分泌素刺激后管腔内和血液中免疫反应性胃泌素(IG)的释放情况。分离胰腺旁十二指肠一段约8～10cm,分别对肠系膜上动脉、脾动脉、门静脉、胰管和十二指肠远近端作插管。在室温下用闭式循环灌注机和特制灌注液通过肠系膜上动脉和脾动脉作灌注, The authors used in vitro hemoperfusion of 6 dog pancreaticoduodenal specimens to investigate the release of immunoreactive gastrin (IG) in the lumen and blood following basal conditions and stimulation with secretin. Separation of pancreatic duodenal section of about 8 ~ 10cm, respectively, on the superior mesenteric artery, splenic artery, portal vein, pancreatic duct and duodenal distal intubation for intubation. At room temperature with a closed loop perfusion machine and special perfusion fluid through the superior mesenteric artery and splenic artery for perfusion,
