Beeinflussung von Enzymaktivitäten in menschlichem Blut durch Gerinnungsvorgänge und Thrombozyten-Desintegration

Variations of Plasmatic Enzymes during Exercise

“…Enzymatic activities vary if measurements are made in plasma or in serum. Kluge and Haug [44] demonstrated that enzymatic activity of LDH was a little higher in plasma than in serum, and was increased when the latter was overloaded with in creasing quantities of platelets. When clotting was provoked and serum separated immediately, enzymatic activity increased just by the contact be tween blood cells and plasma.…”

“…Urinary enzymes are often nothing else than enzymes originating from leucocytes [19]. Finally, we must consider platelets, which have a similar behavior [27,44,46]. They decay or are perturbed by coagulation which modifies their membrane resis tance and thus accelerates 'release' of enzymes.…”
