摘要: 目的 研究慢性疲劳综合征(CFS)患者血中是否存在色氨酸水平的改变.方法 采用美国CDC的诊断标准,应用高效液相色谱的检测方法,对CFS患者血中色氨酸的水平进行测定,并与经过严格筛查的健康人比较.结果 CFS人群血浆中色氨酸的水平(32.03±5.33)μmol/L明显高于健康人组(22.49±4.26)μmol/L,差异具有统计学意义(P<0.01).结论 以色氨酸为起始的5-羟色胺(5-HT)能系统功能紊乱可能是CFS发生"中枢性"疲劳的生化基础之一.

Abstract: Objective To determine the changes in tryptophan levels in the chronic fatigue syndrome(CFS) patients.Methods The levels of tryptophan in the plasma of CFS patients were determined by HPLC.The patients and healthy persons were selected according to the CDC criteria.Results The levels of tryptophan in CFS(32.03±5.33)μmol/L increased significantly when compared those in controls(22.49±4.26)μmol/L.Conclusion Serotonergic dysfunction that initially came from the metabolitic disturbance of trytophan in the plasma might be one of the pathogenetic factors for CFS.

Key words: chronic fatigue syndrome, tryptophan, 5-Hydroxytryptamine, pathogenesis
