    Abstract:
    Nitric oxide produced in various human tissues by nitric oxide synthase is involved in the regulation of many physiological processes. Mechanism of its action is diverse. The most important physiological activity of nitric oxide is guanylate cyclase activation and an increase of cGMP synthesis. At low concentrations NO plays a pivotal role in vessel relaxation and possesses antithrombotic, antiproliferative and anti-inflammatory features as well. An excessive production of nitric oxide can disturb vascular hemostasis and contribute to development of cardiovascular diseases. Studies provide that NO also participate in fibrynolysis regulation by the influence on the PAI-1 and t-PA expression, what may have important clinical implications. The aim of this review is to present current knowledge about the role of nitric oxide in the regulation of these plasminogen activation system factors.
