1. Significance of melanin-related metabolites as biochemical markers of melanoma(1) Normal values of 5-S-cysteinyldopa(5-S-CD) and 6-hydroxy-5-methoxyindole-2-carboxylic acid(6H5MI2C) in serum and urine were obtained from 33 healthy Japanese. The urinary excretion of both markers showed significant decrease in elderly subjects as compared with middle-aged subjects, while the serum concentration showed no age-dependent differences.(2) Values of those 4 markers in melanoma patients have regularly been followed. Among the 4 markers serum 5-S-CD appears to reflect most sensitively the progression of melanoma.Some patients showed pathological values of serum 5-S-CD(above 10 nmol/L) prior to the detection by image diagnosis. On the other hand, 6H5MI2C in serum and urine was found to be of little clinical significance.(3) Serum 5-S-CD values have been analyzed every month in 2 years' period in 10 healthy subjects. No values exceeded 10 nmol/L, the upper limit of normal value, in the 240 samples.2. Improvement of HPLC determination of serum 5-S-CD The previous method for the HPLC determination of serum 5-S-CD required 80 min for each chromatographic run. Pre-treatment of serum samples has been improved to reduce the time for each analysis to 40 min, which enabled to double the analytical capacity.

1.黑色素相关代谢物作为黑色素瘤生化标志物的意义（1）测定了33名健康日本人血清和尿液中5-S-半胱氨酰多巴（5-S-CD）和6-羟基-5-甲氧基吲哚-2-羧酸（6 H_5 MI_2C）的正常值。与中年受试者相比，老年受试者的这两种标志物的尿液排泄量显着减少，而血清浓度没有显示出年龄依赖性差异。(2)这4种标记物在黑色素瘤患者中的值已定期随访。其中血清5-S-CD对黑色素瘤的进展最为敏感，部分患者在影像学诊断前血清5-S-CD已超过10 nmol/L。而血清和尿液中的6 H5 MI 2C则无临床意义。(3)本文对10名健康人的血清5-S-CD值进行了2年每月测定。240份样本中，没有一份超过正常值上限10 nmol/L.血清5-S-CD高效液相色谱测定方法的改进以前的血清5-S-CD高效液相色谱测定方法每次色谱运行需要80 min。改进了血清样品的预处理，将每次分析的时间减少到40分钟，从而使分析能力增加一倍。
