Abstract
In prolonged labour (dystocia) the level of activity of the enzyme oxytocinase is increased in the plasma and decreased in the placenta; the ratio of its activity in the placenta to that in plasma is less than half that found in normal labour. A possible explanation is that oxytocinase is derived mainly from the placenta and that during prolonged labour the enzyme escapes into the maternal blood stream.
摘要
在产程延长（难产）时，血浆中催产素酶的活性水平升高，而胎盘中的活性降低；其在胎盘与血浆中的活性比值不到正常产程时的一半。一种可能的解释是，催产素酶主要源自胎盘，在产程延长期间，该酶逸入母体血流中。
