Thirty amniotic fluid samples in late gestational age were analysed for HPL-values and the L/S-ratio. The pregnant women used in this study were healthy except three patients who developed a rh-incompatibility. The amniotic fluid was only obtained by abdominal amniocentesis. We found a decreasing tendency of the HPL-values in late pregnancy. The L/S-ratio increased. A significant correlation of both values could not be observed. In all three cases of rh-incompatibility the decrease of HPL and the increase of the L/S-ratio occurred obviously earlier and steeper. Further studies will prove the significance of these results.
对30份孕晚期羊水样本进行了人胎盘催乳素（HPL）值和卵磷脂/鞘磷脂（L/S）比值分析。本研究中使用的孕妇除3例发生Rh血型不合外均健康。羊水仅通过经腹羊膜腔穿刺获取。我们发现妊娠晚期HPL值有下降趋势，L/S比值升高。未观察到这两个值之间存在显著相关性。在所有3例Rh血型不合病例中，HPL的下降和L/S比值的升高明显更早且更陡峭。进一步的研究将证实这些结果的意义。
