Free, bound, and total plasma tryptophan (F.P.T., B.P.T., and T.P.T.) levels have been measured throughout the night in six young female volunteers. All-night polygraphic sleep recordings were also made. No direct temporal relationship was found between plasma tryptophan levels and specific sleep stages. The mean F.P.T. levels, however, were found to have a positive correlation with rapid-eye-movement (R.E.M.) sleep and a negative correlation with non-R.E.M. sleep. An inverse relationship existed between the F.P.T. and B.P.T. levels. There appeared to be a diurnal variation in F.P.T. levels, with high readings in the first half of the night.
在六名年轻女性志愿者中，对她们夜间的游离、结合及总血浆色氨酸（F.P.T.、B.P.T.和T.P.T.）水平进行了测量。同时还进行了整夜的多导睡眠记录。未发现血浆色氨酸水平与特定睡眠阶段之间存在直接的时间关系。然而，发现平均F.P.T.水平与快速眼动（R.E.M.）睡眠呈正相关，与非快速眼动睡眠呈负相关。F.P.T.和B.P.T.水平之间存在反比关系。F.P.T.水平似乎存在昼夜变化，夜间前半段读数较高。
