[Immunologic indicators in mothers of low birth weight infants].

Neutrophil function, circulating immune complexes, major immunoglobulins and lysozyme activity have been determined in mothers of 86 newborns, of whom 24 were term infants with normal birthweight, 27 had first-degree prematurity and 35 were term newborns with low-birth weight. The mothers of premature newborns showed prominent impairment of bactericidal properties and functional stores of neutrophilic phagocytes, while mothers of term newborns with low-birth weight had abnormalities of humoral immunity.
