title: Immunologic alterations in the third trimester of pregnancy.
abstract: In a study carried out in a group of 61 pregnant women in the 21st to the 41st week of gestation and comparatively in 9 nonpregnant controls, the following were determined: changes in the leukocyte and lymphocyte count, proportion of T cell rosettes, T1 rosettes (TM cells), T2 rosettes (TG cells), EAC rosettes (B cells), EACD rosettes (killer cells), circulating NBT-positive phagocytes, serum IgG, IgA, IgM and C3 concentrations, 50% hemolytic activity of the complement system. The results are interpreted in the light of present data regarding the mechanisms of ovo-embryo-fetal allograft.
