Abstract

It has been shown by use of isolated, perfused rat kidneys that hypertensin II is a potent vasoconstrictor substance while hypertensin I is not. Hence it would appear that in intact animals the pressor activity of hypertensin I results from its rapid conversion to hypertensin II. An enzyme which effects this conversion has been procured from horse plasma in a semipurified form by means of ammonium sulfate fractionation and isoelectric precipitation. A method is described for estimating the activity of the enzyme. An example of the use of the preparation in converting purified hypertensin I to hypertensin II has been described.

摘要

利用离体灌注大鼠肾脏的实验表明,血管紧张素II是一种强效血管收缩物质,而血管紧张素I则不是。因此,在完整动物体内,血管紧张素I的升压活性似乎源于其迅速转化为血管紧张素II。通过硫酸铵分级分离和等电沉淀法,已从马血浆中以半纯化形式获得了一种能实现这种转化的酶。本文描述了一种估算该酶活性的方法。还介绍了该制剂用于将纯化的血管紧张素I转化为血管紧张素II的一个实例。
