[Effect of the blockade of alpha- and beta adrenergic receptors on the release of hemocoagulating compounds from the intestine into the blood].

In acute experiments on cats, tropaphen (alpha-adrenoreceptor blocking agent) sharply increased the release of antithromboplastins into the intestinal vessels. The beta-adrenoreceptor blocking agent obsidan inhibited the antithromboplastin release. Both agents practically did not affect the intensity of release of other factors of blood coagulation and fibrinolysis. The control of antithromboplastin release in the intestine seems to occur with active participation of structures close by their features to alpha- and beta-adrenoreceptors.
