[Dependence of the thrombocyte aggregation reaction on plasma fibronectin and the tripeptide arginyl-glycyl-asparagilin].

If was shown that the addition of fibronectin antibodies exerted the inhibition of platelet aggregation. The tripeptide RGD inhibited the platelet aggregation induced by the same agents (ADP, epinephrine, thrombin, collagen) both in blood plasma and in suspension of washed platelets.
