[Correlation between thrombocytes and fibrinolysis].

After a concise review of the fibrinolysis modifying effect of platelets, a simple, reliable and reproducible in vitro microplate clot-lysis method is described which is able to demonstrate the lytic resistance of platelet rich clots. The same method proved to be suitable to show the enhanced lysis in platelet rich lytic environment, caused probably by plasminogen attached to platelet surface. The results discussed here suggest that these effects need the presence of intact platelets.
