Regulación antitrombótica por la fibrinólisis / Antithrombotic regulation by fibrinolytic system

In this work it is emphasized the presence of the fibrinolitico system in different physiological mechanisms, specially in the antithrombotic regulation of the hemostasis. It is described: the mechanism of activation of plasminogen by their activators as much on the fibrin as in the cells surface; the inhibition of the activators in different metabolic alterations.
