Summary
Global fibrinolysis and activator activity were investigated in venous blood before
and after occlusion. Global fibrinolysis was determinated by thrombelastography with
a low speed of the paper drive (longterm thrombelastography). The fibrinolysis on
the thrombelastographic curves were evaluated by the slant (a°) of the inflectional
tangent at the thrombelastographic branch.
A considerable increase of global fibrinolytic activity and also of the activator
activity after venous congestion was found. There was a slight correlation between
the global fibrinolysis and the activator before occlusion and a strong correlation
after congestion. There was, however, no accordance between the regression lines of
the two correlations. Other factors of activation of fibrinolysis may be involved.
