title: Correlations of sialomucins and IgA in the maternal serum of primiparous and multiparous subjects at delivery.
abstract: Attention is drawn to correlations between placental coefficients and maternal serum levels of IgA at delivery in primiparae and multiparae. These correlations associate maternal serum IgA with gestational performance and appear to discriminate between groups which differ in that respect. Similar correlations exist between the placental coefficient and maternal serum seromucoid, with group discrimination preserved in primiparae, but not multiparae. Direct correlations between serum seromucoid and IgA in maternal serum can be attributed to their mutual dependence on the size and state of the feto-maternal interface, and may provide a means of detecting placental insufficiency in multigravidae.
