本文用氮平衡法测定了11名10 ~ 12岁男童对色氨酸、精氨酸和组氨酸的最低需要量。还测量了肌酸、肌酐、核黄素和N-MNA的尿排泄。所有儿童在精氨酸和组氨酸剥夺期间保持恒定的体重和正氮平衡，没有任何伴随的临床症状。所有儿童在0.12 g色氨酸水平上都能保持正平衡，但有些儿童在0.06 g色氨酸水平上不能保持正平衡。总结了我们在儿童中使用10种氨基酸进行的所有实验中获得的结果。
Minimal requirements for tryptophan, arginine and histidine of eleven 10- to 12-year-old boys were estimated by using the N balance method. Urinary excretion of creatine, creatinine, riboflavin and N-MNA was also measured. All children maintained a constant body weight and positive N balance without any accompanying clinical symptoms throughout the periods of arginine and histidine deprivation. All children maintained a positive balance at a level of 0.12 g of tryptophan, but some of them could not maintain a positive balance at the level of 0.06 g. The results obtained in all of our experiments with 10 amino acids in children are summarized.
