摘要

采用高透酸清除法，通过电磁测量门静脉、胃左动脉血流和胃黏膜血流，探讨十二指肠内容物酸化对麻醉犬内脏血流和胃循环的影响。十二指肠酸化增加门静脉血流，降低肠系膜流入阻力。同时，胃动脉和粘膜的血流量(不明显)由于流入阻力增加而减少。

The effect of duodenal acidification on gastric circulation and function in the dog.

The effect of acidification of duodenal contents on splanchnic bloodflow and gastric circulation was investigated in anaesthetized dogs by measuring electromagnetically portal venous and left gastric artery bloodflow and gastric mucosa bloodflow with pertechnetate clearance. Duodenal acidification increased portal venous bloodflow and reduced mesenteric inflow resistance. At the same time bloodflow in the gastric artery and (not significantly) in the mucosa were reduced in consequence of increased inflow resistances.
