In an unselected material of placentas (507 cases) with classified newborns (percentile of the GDR) we estimate the weight of the placenta, the placental quotient (PQ) and the dimension of the uteroplacental junction area. Between the weight of newborn and the weight of placenta exists a high degree of relationship in the whole material as well as in the singular percentile groups. The placental quotient doesn't show any changes of the normal value. Between the size of the uteroplacental junction area and the weight of newborn there is a moderate relationship. These results substantiates the suspicion manifested earlier and similar semiquantitative studies in the same matter of our own. The functional significance of these relationship in the pathogenesis of the "small-for-dates" is discussed.
在一组未经挑选的胎盘材料（507例）中，针对分类后的新生儿（根据胎儿生长发育比值百分位数），我们估算了胎盘重量、胎盘商（PQ）以及子宫胎盘交界区的尺寸。在整个材料组以及各个百分位数分组中，新生儿体重与胎盘重量之间都存在高度相关性。胎盘商未显示出正常值有任何变化。子宫胎盘交界区大小与新生儿体重之间存在中等程度的相关性。这些结果证实了我们之前所表现出的怀疑，以及我们自己在同一问题上进行的类似半定量研究。本文还讨论了这些相关性在“小于胎龄儿”发病机制中的功能意义。
