摘要 目的 建立一种快速、准确的脑内兴奋性氨基酸定量检测方法。方法 采用 6 30 0黄金系统氨基酸分析仪 ,在锂柱 130min程序生理体液分析方法基础上 ,根据兴奋性氨基酸 (EAAs)的特性 ,建立了EAAs的快速测定方法。结果 此方法完成兴奋性氨基酸分析的时间是 2 0min ,比原方法缩短了 110min ;且有较好的重现性 (GluCV :日内 1 86 % ,日间 2 32 % ;AspCV :日内 1 42 % ,日间 2 48% )和回收率 (Glu 97 7% ;Asp 97 3% )。并用此方法观察了高原低氧大鼠下丘脑EAAs的含量变化。结论 本方法定量检测兴奋性氨基酸快速、准确 ,并利于大批量样品的快速测定。
