[The turnover of three amino acids in the plasma of chronic renal failure patients].

In this study, three amino acids (Ala, Leu and Phe) labelled with stable isotopes were administered to a group of CRF patients and of normal controls, respectively. Based on the measurement of gas chromatography and mass spectrometry, a series of kinetic parameters of amino acid metabolism were calculated and the differences between the two groups were compared.
