title: [The ultrastructure of the cord blood lymphocytes of newborn infants in normal and complicated pregnancies].
abstract: Ultrastructure of the umbilical cord blood lymphocytes was studied in full-term newborns with mothers suffering from toxemia (nephropathy) of the pregnancy second part and without any pathology, in part-term newborns and adult donors. Lymphocytes demonstrated in newborns were the same as in adults (small light, small dark, medium and large ones) with their ultrastructure close to that of adults. Morphometric analysis revealed signs characteristic for newborn lymphocytes. Second and third group newborns were found to have pathological changes in part of lymphocytes concerning both nucleus and cytoplasm and also some morphometric peculiarities. They are manifested as different in expression and direction in different types of lymphocytes of absolute and relative square of mitochondrial section and as signs of synthetic processes activation in all types lymphocytes.
