血管紧张素(AT)是一种肽类血管活性物质,是肾素——血管紧张素——醛固酮系统的组成部分。血浆中AT 转化酶活性很低,但肺组织AT 转化酶含量却很丰富,是血管紧张素Ⅰ(AT Ⅰ)转化为血管紧张素Ⅱ(AT Ⅱ)主要场所。本文对20例正常人,42例肺心病急性发作期患者,10例慢性支气管炎合并肺气肿(以下称慢支肺)无肺心病患者,采用放射免疫法分别测定血浆AT Ⅱ,对其结果进行比较
Angiotensin (AT) is a peptide vasoactive substance that is part of the renin-angiotensin-aldosterone system. The activity of AT in plasma is very low, but AT is very abundant in lung tissue. It is the main site for the conversion of angiotensin Ⅰ (AT Ⅰ) to angiotensin Ⅱ (AT Ⅱ). In this paper, 20 normal subjects, 42 patients with acute episodes of pulmonary heart disease, 10 patients with chronic bronchitis complicated with emphysema (hereinafter referred to as chronic bronchitis) without pulmonary heart disease, were measured by radioimmunoassay of plasma AT Ⅱ, the results Compare
