[Importance of the functional activity of thrombocytes and the antiaggregation activity of the vascular walls in regulating blood aggregation].

It was established in dog experiments that aggregation activity of platelets and the rate of aggregation were higher in arterial than in venous blood, with the platelet content being identical. Antiaggregation activity of vascular walls of the arterial system. The data obtained indicate the presence of the arteriovenous difference of the function of the vascular-platelet hemostasis, which is of a role in the processes of regulating the state of blood aggregation in the body.
