血管紧张素有许多不同的作用,其中大多数直接或间接地调节血压和水、电解质平衡;对血管系统有明显的血管收缩作用;促进前列腺素的释放,调节血管紧张素受体的数量;另外,它对中枢和周围神经系统、肾上腺、肾脏、肠和心脏也有重要作用。本文综述了有关循环肾素——血管紧张素系统(Circulat-ing renin-angiotensin system RAS)产生血管紧张素的新概念;组织生成血管紧张素以及两者的关系;转变酶抑制利(CEIS)降血压的可能机制。 Angiotensin has many different roles, most of which directly or indirectly regulate blood pressure and water and electrolyte balance; vasoconstrictor effect on the vascular system; promote the release of prostaglandins, regulate the number of angiotensin receptors; in addition , It also plays an important role in the central and peripheral nervous system, adrenal, kidney, intestine and heart. This article reviews the new concept of angiotensin production by the circulatory-renin-angiotensin system (RAS), the tissue angiotensin-converting enzyme (angiotensin II), and the relationship between the two Possible mechanism of blood pressure.
