Abstract

Patients with chronic renal disease had low plasma total tryptophan but an abnormally high proportion of this was in the free state. The subjects with encephalopathy had raised plasma free tryptophan, CSF tryptophan, and CSF 5-hydroxyindoleacetic acid. CSF tryptophan correlated better with plasma free than with plasma total tryptophan. Plasma and CSF tyrosine concentrations were normal but CSF homovanillic acid was raised especially in subjects with encephalopathy. The possible significance of these changes in advanced renal disease is discussed.

摘要

慢性肾病患者血浆总色氨酸水平较低,但其中处于游离状态的比例异常高。患有脑病的受试者血浆游离色氨酸、脑脊液色氨酸和脑脊液5-羟吲哚乙酸水平升高。脑脊液色氨酸与血浆游离色氨酸的相关性比与血浆总色氨酸的相关性更好。血浆和脑脊液酪氨酸浓度正常,但脑脊液高香草酸水平升高,尤其是在患有脑病的受试者中。本文讨论了晚期肾病中这些变化的可能意义。
