The cancers studied here were throat cancer, aute non- lymphoblas He leukem ia and acut lymphoblastic leukemia. The result s indicated that,(1)the levels of Leu, Lys, Ser Asn,Ile,Gly,and Thr were obviously decreased whea lse the levels of orn, Trp evidently increased in cultural liquid of throat can cer cell line indicating that the growth of HepⅡ cell consumed 7 amino acids and releaced 2 amino acids into cultural liquid.(2)the levels of Glu, Gls, Leu, Phe, Tyr and Trp were evidently increased while the levels of Thr , His, Ala decreased in plasma from patient with ANLL. These r esults were consistent with the previous report.(3)the levels of Gly, Trp and Phe in plasma from patients with ANLL evidently de creased and the levels of Ala, His increased after therapy indicating that cance r cells were growing in an anaerobic catabolism state.
