The cell morphology of long-term cultures of amniotic fluid cells from 10 fetuses with a neural tube defect (NTD) and three with omphalocele was examined and compared to 30 long-term cultures of normal amniotic fluids as well as a long-term culture of human fetal brain. Cultures from the amniotic fluids of the fetuses with NTD and omphalocele showed cells(More)
IgG, IgM and albumin levels in sera from neonates with open neural tube defects (NTD), other congenital malformations, and matched controls were measured, as were levels in sera from their mothers. Neonates with NTD had significantly lower serum IgG levels than 22 control neonatal sera. On the other hand, the mothers of these neonates with NTD had elevated(More)
Amniotic fluid cells from normal and abnormal fetuses (neural tube defects and abdominal wall lesions) were examined uncultured and after short-term culture for macrophages. Morphology, adherence, phagocytosis, presence of Fc receptors and non-specific esterase were studied. The existence of macrophages in normal and abnormal fluids was confirmed, although(More)
Looking for intersexual differences in size and lineal and craniofacial proportionality, assumed to be secondary to genetic induction, non-distorted by environmental factors, we studied 200 newborns from families who were residents in proletarian zones, parents with very similar education and employment (qualified workers). We chose 15 size measurements(More)
Amniotic fluid cells have been widely used in prenatal diagnosis; however, there is great heterogeneity of the cells and their origin. In this study we analyze the karyotype and release of human chorionic gonadotropin (hCG), human chorionic somatomammotropin (hCS), free estriol (E 3), prolactin (PRL) and progesterone (P) of amniotic fluid cells from primary(More)
