[The kallikrein-kinin system of the blood in gestosis].

Blood kallikrein-kinin system (KKS) was studied in 80 pregnant women with gestoses of various severity and in 20 females with normal pregnancy. Kinin-formation and degradation were analysed and the exhaustion of these processes stated. Its degree was found in proportion with gestosis severity. Prekallikrein levels depended on the predominance of hypertensive disease or albuminuria occurrence. The aforementioned exhaustion possibly resulted from the preliminary activation of kallikrein-kinin system links which took place at the initial stages of gestosis to promote the adjustment of female circulation to increased loads.
