Abstract
The concentrations in plasma and erythrocytes of free amino acids before, during and after cardiopulmonary by-pass have been determined. During by-pass and the early postoperative period the total alpha-amino nitrogen decreased, mainly because of changes in glucogenic amino acids; ketogenic amino acids, on the other hand, increased. The phenylalanine/tyrosine ratio was markedly increased in all cases.
摘要
已经测定了体外循环前、中、后血浆和红细胞中游离氨基酸的浓度。在体外循环期间和术后早期，总α-氨基氮减少，主要是由于生糖氨基酸的变化；另一方面，生酮氨基酸增加。在所有病例中，苯丙氨酸/酪氨酸比值均显著升高。
