Phagocytosis of microspheric hydrophile particles (MSHP) by peripheral blood glass-adherent phagocytes of newborns.

The phagocytic activity of glass-adherent peripheral blood leukocytes of 58 healthy term newborns and 19 adult donors was examined using a micromethod employing a new type of synthetic hydrophilic particles based on 2-hydroxyethylmethacrylate. It was found that both the proportion of actively phagocytosing cells and the number of engulfed particles within the cells was significantly lower in neonates as compared with adults.
