[Tissue type plasminogen activator and its inhibition in blood of patients operated on for prostatic carcinoma].

In 30 patients with prostatic carcinoma a higher of t-PA, a low of PAI-1, alpha 2-antiplasmin and plasminogen activity with increased fibrin degradation products (FDP) level and a short euglobulin lysis time (ELT) were observed. Following surgery a further increased of fibrinolytic activity occurred. The activity of t-PA and PAI-1 were higher than before operation. Apart from that we observed a decreased of plasminogen and alpha 2-AP with further increased level of FDP. On 5-th day the values of examined parameters were similar as before the operation.
