title: [Effect of fetoplacental factors on in vitro proliferation of lymphocytes and non-lymphoid cells].
abstract: The effect of extracts of placenta, amniotic fluid, serum of pregnant women and newborn infants on PHA-stimulated proliferative activity of lymphocytes and proliferation of non-lymphoid cells (L-cells) was studied. The inhibiting effect decreased in the series: placenta -- amniotic fluid -- serum of pregnant women. The effect on L-cells was similar to that on lymphocytes. It is suggested that the biological samples under study contained factors having non-specific immunosuppressive effect.
