Abstract/OtherAbstract:
In order to see whether the mother contributes to the vasopressin or oxytocin levels of amniotic fluid, these peptides were measured under conditions (1) in which the fetus lacks vasopressin (Brattleboro strain) and (2) where high maternal oxytocin and vasopressin plasma levels were induced by means of a controlled-delivery Accurel-collodion device. No vasopressin could be demonstrated in amniotic fluid of vasopressin-deficient fetuses present in a heterozygous (i.e., vasopressin-synthetizing mother). High peptide levels on the maternal side of Wistar rats generally failed to affect the amniotic fluid levels. The increase that was occasionally seen in amniotic vasopressin was probably due to fetal release concomitant with growth retardation. Amniotic vasopressin is derived from the fetus. Since amniotic fluid oxytocin is neither derived from the mother nor from the fetal brain, other fetal sources should be considered.
