title: [Plasma kininogenesis and fibrinolysis in the pathogenesis of EPH gestosis].
abstract: The coexistence of arterial hypertension and disturbances of haemostasis in pregnant women with EPH-gestosis allow to expect a role of fibrinolysis and kinin-forming systems in pathomechanism of this syndrome. For these reasons blood plasma of 34 patients with EPH-gestosis, 23 patients with normal pregnancy and 19 nonpregnant women was investigated. All pregnant women were in third trimester of pregnancy. The following parameters were investigated: kinin-forming system compounds (kininogens and prokininogenases - biological methods), fibrinolytic activity (plasma euglobulin fibrinolysis time), total plasma protein and fibrinogen concentration, protease inhibitors - antithrombin III, C1-esterase inhibitor, alpha 2-antiplasmin, alpha 1-protease inhibitor and alpha 2-macroglobulin (by electroimmunodiffusion). Furthermore hematocrit was measured. In pregnant women with EPH-gestosis significant increase of high molecular weight kininogen concentration was found (p less than 0.02), decreased fibrinolytic activity (p less than 0.01) and (except alpha 2-antiplasmin) decreased concentration of protease inhibitors (p less than 0.005 - p less than 0.01) were observed. Further statistical analysis demonstrated positive correlation between the concentrations of kininogens and prokallikrein-prokininogenases and between low molecular weight kininogen and plasma euglobulin fibrinolysis time. On the other hand negative correlation between concentrations of those proenzymes and severity of gestosis was observed. The above described phenomena indicate on significance of disturbances of proteolytic enzyme activation in pathogenesis of EPH-gestosis.
