[Size of uteroplacental adhesive area and weight of placenta compared with weight of newborn (author's transl)].
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.
