近10年来,人们越来越重视对肺代谢功能的研究。肺除气体交换外,还参与许多生物活性物质合成、释放和代谢。肺循环通过调节动脉血的化学成分,执行着重要代谢功能。在人类,每20秒钟,全部血客量都能通过肺脏。它们的成分改变主要通过以下几个机理:1.血浆成分的摄取,继之部分或全部酶的灭活;2.在未摄取前,部分或全部作用血浆底物酶的灭活;3.来自肺组织成分活性物质的形成;4.来自血液成份的活性物质形成。通过这些机理,肺控制一些激素、生物
In the recent 10 years, people pay more and more attention to the study of lung metabolism. In addition to gas exchange, the lungs are also involved in the synthesis, release and metabolism of many bioactives. Pulmonary circulation, by regulating the chemical composition of arterial blood, performs important metabolic functions. In humans, every 20 seconds, the full amount of blood can pass through the lungs. Changes in their composition mainly through the following mechanisms: 1. Plasma composition uptake, followed by the inactivation of some or all of the enzyme; 2. Before ingestion, some or all of the role of plasma substrate enzyme inactivation; 3. From Formation of Active Ingredient of Lung Tissue Component; 4. Formation of Active Material from Blood Component. Through these mechanisms, the lungs control some hormones and creatures
