title: [Immunologic status in physiological pregnancy].
abstract: The levels of T gamma- and T mu-lymphocytes, functional activity of ConA-induced T-suppressors and the concentrations of SP1 and SP3 were determined in 164 normal pregnant women during 8-40 weeks of gestation. It is found that formation of the suppressor dominant is necessary for the immunological maintenance during 8-32 weeks of gestation. This dominant is intended to block superfluous maternal immune response to fetal alloantigens. The formation of such a dominant is evoked by high functional activity of ConA-induced T-suppressors and high levels of T gamma-lymphocytes with immunodeficiency of T mu-cells. Results of correlation analysis have shown a relationship between functional activity of T-suppressors and accumulation of two specific pregnancy proteins. It permits determining physiological role of SP1 and SP3 as natural endogenous immunoregulators of T-suppressors.
