Summary

By use of staining with toluidine blue, the changes in the nucleoli of lymphocytes in 150 healthy women were studied. The patients were divided into five groups: non-pregnant women; women in the first, second and third trimesters of pregnancy; and women who were five days post parturn. A progressive and statistically significant rise in the number of lymphocytes with micronucleoli was found during pregnancy and there was a fall after delivery. This increase was associated with a decrease in the incidence of ring-shaped nucleoli. There were no significant changes in the absolute number of lymphocytes and in “active” lymphocytes during pregnancy.
