“静脉内高营养”是近年来临床医学的一项新技术,本文研究了这种营养液的稳定性。作者首先将8.5％结晶氨基酸溶液500毫升加入50％葡萄糖500毫升内,两者混和后共分为15瓶。取5瓶为一组,用来分析葡萄糖和α-氨基氮的含量,溶液pH滴定酸度作为基数;第二组5瓶置冰箱内(4℃);第三组5瓶置室温中。另外将10％水解蛋白500毫升与50％葡萄糖500毫升混合,共15瓶同上处理。葡萄糖和α-氨基氮的含量测定按美国 “Intravenous high nutrition” is a new technology in clinical medicine in recent years. This paper studies the stability of this nutrient solution. The authors first 500 ml of 8.5% crystalline amino acid solution was added to 50% glucose 500 ml, the two were mixed and divided into 15 bottles. Take 5 bottles as a group, used to analyze the content of glucose and α-amino nitrogen, pH titration solution as the base; the second set of 5 bottles of refrigerator (4 ℃); the third group of 5 bottles at room temperature. In addition, 500 ml of 10% hydrolyzed protein and 500 ml of 50% glucose were mixed, and a total of 15 bottles were treated as above. Glucose and α-amino nitrogen content by the United States
