Summary

The fibrinolytic and esterolytic activity of the plasma before and after activation with Streptokinase is studied. The inhibitors of plasmin are neutralized by the acidification of the plasma or by the acetone treatment. The inhibitors of the “trypsin like enzymes” are neutralized only by acetone. The hydrolysis of the BAEE by the acetone treated and activated plasma seems to be a satisfactory method for the simultaneous determination of the total (plasmin-plasminogen) activity and the total activity of the (trypsin like enzymes) with arginine exopeptidase activity.
