Abstract
PROBLEM: The chronic placental insufficiency is the most common cause of intrauterine hypoxia, retardation of fetal growth, and other threatening conditions. Immune disturbances may occur in the system "mother-placenta-fetus." METHOD OF STUDY: Biochemical blood indicators were studied on an automated biochemical analyzer. Pattern of lymphocyte subpopulations was detected by direct membrane immunofluorescence. RESULTS: Study revealed imbalance of immune parameters, caused by placental insufficiency (increase natural killers (CD16(+) , CD56(+) ), B lymphocytes (CD19(+) CD3(-) ), T and B lymphocytes with HLA-DR(+) antigen, and early activation of immune cells (by CD25(+) ), as well as disorders in apoptotic mechanisms (by CD95(+) )). CONCLUSION: Placental insufficiency leads to abnormalities of the immune system in pregnant, parturient women and maternity patients which were evaluated by localization of activation markers CD25(+) CD95(+) on the CD3(+) , CD4(+) , CD8(+) , CD16(+) , CD56(+) lymphocytes. This is reflected in the change of lymphocyte functions in newborns.
