摘要  目的:建立精浆游离肉碱的测定方法。方法:用高效液相色谱法测定正常人与不育症患者的精浆游离肉碱。结果:方法线 性范围为12.5~500μmol·L-1;最低检测浓度为5μmol·L-1,总分析时间6.7min。肉碱平均保留时间(5.24±0.19)min。高、中、 低3种浓度的平均回收率为86.93%。批内、批间RSD分别为5.3%和10.8%。测得正常人与精子异常症病人精浆游离肉碱浓度分 别为(903.8±470.1)(n=20)和(308.1±156.2)μmol·L-1(n=20),两者差异有极显著性(P<0.01)。结论:HPLC法测定精浆游 离肉碱浓度灵敏、可靠、简便,适用于快速检测肉碱缺乏症病人的临床筛选工作。 OBJECTIVE To develop a method for the determination of free carnitine in sperm.METHODS Free carnitine in sperm from healthy persons and infertilitas patients was deter mined by a high-performance liquid chromatographic method (HPLC). RESULTS The linearity of the method ranged from 12.5 μmol·L - 1 to 500 μmol·L -1 of carnitine. The detect limit of the carnitine in sperm was 5 μmol·L -1. Retention tim e (R t) for the nutrition was (5.24 ± 0.19) min and a single run totally took up 6.7 min only. T...
