title: Studies of blood coagulation-fibrinolysis regarding kallikrein-kinin system in severe preeclampsia.
abstract: In our previous study 1), 2), 3) we reported the changes of coagulation-fibrinolysis, kallikrein-kinin system and kininase in preclampsis. In this study, we tried to obtain systemic information of chronic DIC status with regard to kallikrein-kinin system in severe preeclampsia. This systemic information was evaluated in 20 cases of normal gravidas from 28 to 42 weeks of gestation as a control by measuring plasma Thrombin/Antithrombin III complex (TAT), tissue plasminogen activator (tPA) plasminogen activator inhibitor (PAI) complex, active plasminogen inhibitor-1 (active PAI), 2PI plasmin complex (PIC).
  
  
  RESULTS
  The levels of plasma TAT and tPA significantly increased (TAT = 10.9 +/- 8.3 ng/ml n = 24 M +/- SD P < 0.02, tPA = 6.1 +/- 3.2 ng/ml n = 10 M +/- SD P < 0.01), tPA PAI C and active PAI markedly increased (tPA PAI C = 85.07 +/- 50.01 ng/ml n = 24 P < 0.05, active PAI = 407.4 +/- 166.0 ng/ml n = 24 P < 0.205), and PIC and D-dimer = 435.1 +/- 145.2 ng/ml n = 8 M +/- SD P < 0.001) in severe preeclampsia as compared with those of normal values (TAT = 6.1 2.0 ng/ml, tPA = 3.6 +/- 1.5 ng/ml, tPA PAI C = 57.9 +/- 30.8 ng/ml, active PAI = 304.2 +/- 148.6 ng/ml, PIC = 0.49 +/- 0.24 mg/ml, D-dimer = 282.9 +/- 75.3 ng/ml).(ABSTRACT TRUNCATED AT 250 WORDS)
