4. susceptibility to infection. Polymorphonuclear leucocytes (PMNs) provide the major defence against bacterial infection. The increase in oxidative metabolism (OxM) that accompanies phagocytosis by these cells is unquestionably required for efficient antibacterial activity;and phagocytic (Coen;et al; Accordingly, many investigators have assessed postphagocytic OxM of PMN from newborns. Results have been contradictory (Strauss and Mauer,1975
5. final concentration) from the placental side of the divided umbilical cord of healthy, term infants. Contamination with maternal blood was estimated by the acid elution technique (Dacie and Lewis, 1968), and samples with >10% maternal erythrocytes were excluded. Although rarely mentioned in previous reports, this precaution should be a routine procedure when studying cord blood. Several samples consisted almost entirely of maternal erythrocytes (and presumably leucocytes) and would have been assumed, incorrectly, to represent infant blood
