根据生化特性、耐热性、抑制剂、抗原性和电泳泳动力的差异,将人类碱性磷酸酶(AP)同功酶分成4种,胎盘同功酶(PAP)对尿素和热具有较大耐受性,它由合体细胞滋养层合成,在妊娠早期进入母体血液,不少研究表明在21三体胎儿以及唐氏(Down)综合征受累孕妇中性白细胞PAP活性的升高与21三体有关。因此一些学者建议,孕妇中性白细胞PAP可用作产前诊断胎儿染色体异常的一项辅助生化指标。但有些学者未能证实孕妇中性白细胞PAP活性变化与胎儿21三体有关。本文旨在检测妊娠期间中性白细
According to the biochemical characteristics, heat resistance, inhibitors, antigenicity and electrophoretic mobility differences, the human alkaline phosphatase (AP) isozyme is divided into four species, placental isozyme (PAP) of urea and heat have a greater Tolerance, which is synthesized by syncytiotrophoblasts and enters maternal blood in early pregnancy, has shown that elevated PAP activity in neutrophils in pregnant women with trisomy 21 and Down syndrome is associated with increased trisomy 21 related. Therefore, some scholars suggest that pregnant women with neutrophil PAP can be used as prenatal diagnosis of fetal chromosomal abnormalities as a secondary biochemical indicators. However, some scholars have failed to confirm that changes in PAP activity of pregnant women with neutrophils are associated with fetal trisomy 21. This article aims to detect neuter white during pregnancy
