谷氨酰胺是体内最丰富的氨基酸,它虽然不是必需氨基酸,但在体内氨基酸代谢中起着关键作用。谷氨酰胺是由谷氨酸在肌肉和肾内生成。动物实验已经发现谷氨酰胺浓度与肌肉蛋白合成率呈正相关。本实验选其它系统正常的择期胆囊切除者22名,随机分成两组。术后早期三天用同热卡(135kJ/kg/24 h)和同氮量(0.2g/kg/24 h)的TPN。对照组(13人)供普通氨基酸液Vamin;实验组(9人)在此氨基酸液内再加入谷氨酰胺(0.285 g/kg/24 h),但使总氮
Glutamine is the most abundant amino acid in the body and although it is not an essential amino acid, it plays a key role in the metabolism of amino acids in the body. Glutamine is produced in muscle and kidney by glutamate. Animal experiments have found that glutamine concentration and muscle protein synthesis rate was positively correlated. This experiment selected other systems normal elective cholecystectomy 22, were randomly divided into two groups. Three days earlier with the same heat card (135kJ / kg / 24 h) and the same amount of nitrogen (0.2g / kg / 24 h) of TPN. The control group (13) served as the normal amino acid solution Vamin. In the experimental group (9), glutamine (0.285 g / kg / 24 h) was added to the amino acid solution,
