Selective inhibition of secretion of proteinases, amylase and lipase by the pancreas, was revealed. The inhibition is directly dependent on the dose of intraluminal enzymes. The latter's increase transforms the selective inhibition into a generalised one. Possible mechanisms of selective and generalised feedback inhibition of the exocrine pancreatic secretion is discussed, the secretion playing an important role in urgent adaptation of the pancreatic enzymes secretion to the duodenal chyme properties.
已发现胰腺对蛋白酶、淀粉酶和脂肪酶的分泌具有选择性抑制作用。这种抑制作用直接取决于腔内酶的剂量。腔内酶剂量的增加会使选择性抑制转变为全身性抑制。本文讨论了胰腺外分泌选择性和全身性反馈抑制的可能机制,胰腺外分泌在胰腺酶分泌对十二指肠食糜特性的快速适应中起着重要作用。
