目前国内水解蛋白注射液供应不足的主要原因为:(1)原料来源较少(如酪蛋白);(2)酶水解的热原尚难稳定。本文探讨采用酸水解猪全血以制备水解蛋白液的问题。1959年我们利用人全血分浆后的红细胞,藉酸水解制备一种不另加其它氨基酸的水解液。临床应用虽有蛋白质营养疗效与无不良反应,但氮平衡试验不及酪蛋白胰酶水解液为佳。现改用猪全血为原料,水 At present, the main reasons for the shortage of hydrolyzed protein injection in China are as follows: (1) raw materials are less (such as casein); (2) enzymatic hydrolysis of pyrogen is difficult to stabilize. This article explores the use of acid hydrolysis of pig whole blood to prepare hydrolyzed protein solution. In 1959 we use red blood cells after human whole blood plasma, by acid hydrolysis to prepare a hydrolyzate without additional amino acids. Although the clinical application of protein nutrition and no adverse reactions, but less than the nitrogen balance test casein trypsin hydrolyzate better. Pig is now switched to whole blood as raw material, water
