[Influence of materials with different hydrophobic properties on selected parameters of blood coagulation]

In this paper we presented the evaluation and assessment of the influence of the knitted polyester materials with the different hydrophobic properties of theirs surfaces on the blood coagulation and fibrinolysis investigated on dynamic "in vitro" model. On the basis of the received results we can stated that the material with hydrophobic surface do not change the coagulation time in the internal-factors model nor in the external-factor model. It also has no influence for the concentration of fibrinogen, activity of the factors XII and VIII, antithrombin III, protein C nor for plasminogen. The knitted material with the hydrophilic surface increased the coagulation time while use in internal-factors model but do not change the coagulation time in the model with external-factors. It also has the influence in decreasing the activity of the factors XII and VIII. The activity of blood coagulations' inhibitors and plasminogen remained not changed.
