据文献记载,孕16～18周时羊水中出现淀粉酶,36周前其浓度渐增,妊娠最后几周急剧上升。进一步研究表明,羊水中淀粉酶浓度与胎儿成熟度密切相关。判断胎儿成熟度的重要指标为肺功能发育情况,这是以测定羊水中磷脂含量为其依据。本文旨在探讨羊水中淀粉酶浓度和磷脂试验之间关系,并确定羊水淀粉酶测定的临床意义。作者从106例正常孕妇中采得110份羊水标本,对其所含的淀粉酶浓度、卵磷脂/鞘磷脂比例和卵磷脂浓度进行了测定。106例中81例是在孕12～42周期间,经腹壁穿刺抽取羊水,其中4例在不同孕期先后抽取羊水两次;另外25例借羊膜切开术在分
According to the literature, amniotic fluid amylase appears in amniotic fluid between 16 and 18 weeks of gestation, its concentration gradually increased 36 weeks ago, and the last few weeks of pregnancy rose sharply. Further studies have shown that amniotic fluid amylase concentration and fetal maturity are closely related. An important indicator of fetal maturity to determine the development of lung function, which is based on the determination of amniotic fluid phospholipid content. This article aims to investigate amniotic fluid amylase concentration and phospholipid test the relationship between the determination of amniotic fluid amylase determination of clinical significance. The authors collected 110 samples of amniotic fluid from 106 normal pregnant women and determined the amylase concentration, lecithin / sphingomyelin ratio and lecithin concentration. Among the 106 cases, 81 cases were performed amniocentesis through abdominal wall punctures during the period of 12-42 weeks of gestation, of which 4 cases received amniotic fluid twice in different gestations. Another 25 cases were treated by amniotomy
