[Spontaneous proliferative activity of lymphocytes in normal and EPH gestosis complicated pregnancy]

The spontaneous proliferative activity of lymphocytes and CD4+/CD8+ ratio has been estimated in normal and EPH gestosis-affected pregnancy; also the effects of autologous and allogenic sera on this lymphocyte activity was evaluated. Although in normal pregnancy there was a very low CD4+/CD8+ ratio, the spontaneous proliferative activity of lymphocytes and the effects of autologous sera exerted thereupon were the same in either healthy pregnant women or in non-pregnant controls, what indicates a normal cellular immunity in physiological pregnancy. In gestosis an increased proliferative activity of lymphocytes and very high CD4+/CD8+ ratio was observed, when referred to non-pregnant controls. The serum of normal pregnant women did not reveal any immunosuppressive features against the activity of both autologous lymphocytes and gestosis--affected pregnancy, whereas it clearly inhibited the lymphocyte proliferation in non-pregnant controls. A different model of the autologous sera effects on the lymphocyte activity in gestosis women--when compared with the other examined women--is an evidence for altered immuno-modulating parameters of the serum in question.
