Blood samples from over 70 pregnant women have been examined for the presence of four prostaglandins. Samples obtained from women not in labour at different gestation periods and at term contained no detectable amounts of prostaglandins. Prostaglandin F(2alpha) was present in samples of blood obtained during normal spontaneous labour. The appearance of this substance in the blood preceded the uterine contraction. Whether prostaglandins play a part in the process of normal labour is still conjectural.
已对70多名孕妇的血液样本进行了检测,以确定四种前列腺素的存在情况。从处于不同妊娠期及足月但未临产的妇女身上采集的样本中未检测到前列腺素。在正常自然分娩过程中采集的血液样本中存在前列腺素F(2α)。这种物质在血液中的出现先于子宫收缩。前列腺素是否在正常分娩过程中起作用仍属推测。
