肝脏在合成尿素的过程中,精氨酸酶起到一定作用,此酶又为肝脏所特有,故在肝病时测定此酶的活性可能有一定意义。本文根据坂口氏方法(正常值25—30单位),测定10例肝活体组织精氨酸酶的活性,结果如下:脑外伤死者正常肝组织一例为30单位,肝硬化一例为2.5单位;肝癌一例为2.5单位;营养不良症一例为5单位; In the synthesis of urea in the liver process, arginase play a role, this enzyme is unique to the liver, it is possible to determine the activity of this enzyme in liver disease may have some significance. This article according to Sakaguchi method (normal 25-30 units), the determination of arginase activity in 10 cases of liver biopsy, the results are as follows: normal liver tissue of traumatic brain injury in 30 cases, cirrhosis of a case of 2.5 units; a case of liver cancer 2.5 units; one case of malnutrition is 5 units;
