Sialic acid in lymphocytes and sera from mothers and their newborns after normal deliveries.
Sialic acid was determined in newborn and maternal lymphocytes as well as in newborn and maternal serum immediately after normal deliveries. A significant increase in sialic acid in newborn as compared to maternal lymphocytes was found. Sialic acid concentration seems to be sex-dependent for newborn lymphocytes only, and higher concentrations of sialic acid were observed in male as compared to female newborn lymphocytes. No differences between the sialic acid concentration in maternal and control lymphocytes could be found. In newborn serum, sialic acid was significantly reduced as compared to maternal or control serum. No sex-linked differences were observed. No differences between the concentration of maternal and control serum were detected.
