The formation of the fetoplacental complex during gestation is associated with the functional activity of neutrophilic granulocytes (NG) and peripheral blood mononuclear cells (PBMC) [1-5]. In MTT-assay, we investigated the cytotoxic activity (CTA) of NG and PBMC at women with the threat of termination of early pregnancy (n=28), pregnant without complications (n=7) and midgestation period (n=12). It was experimentally established that in women with clinically verified early reproductive complications CTA of neutrophils in vitro significantly (p≤0.05) increased compared to similar indicators in women with physiological pregnancy. High cytotoxic activity of neutrophils and mononuclear cells of peripheral blood is associated with early reproductive losses.
