Administration of Different Catecholamines and Prostaglandin Endoperoxide Formation in Thrombocytes

In patients following myocardial infarction and patients sufferingfrom circulatory shock soluble fibrin in plasma is often elevated as a sign of an activated plasmatic coagulation system. Soluble fibrin is moat pronounced in patients under catecholamine administration. These patients also show an accelerated production of prostaglandin-endoperoxides in thrombocytes indicating concomitant platelet activation. Soluble fibrin was quantified by affinity chromatography and proetaglam-din-endoperoxides were measured after incubation with N-ethylmaleimide as n moles raalondialdehyde. To elucidate the prostaglandin-endoperoxide promoting effect in platelets of epinephrine, norepinephrine and dopamine-these substances are often used to sustain blood pressure and to improve circulation -, the catecholamines were added to platelet rich plasma as well as infused into rabbits. Epinephrine and norepinephrine stimulate prostaglandin-endoperoxide production; in contrast to that dopamine has no effect on platelet endoperoxide formation. This phenomenon may be of favor to avoid at least partly drug induced hypercoagulability and consumption coagulopathy so far as platelet pro-coagulant activities are involved.
