title: Experimental atherosclerosis in rabbits: platelet aggregation, thromboxane A2 generation and anti-aggregatory potency of prostacyclin.
abstract: Experimental atherosclerosis in rabbits was associated with increased aggregation of their platelets to arachidonic acid, and with increased generation of thromboxane A2 by their platelet-rich plasma. A heightened susceptibility of platelets to the anti-aggregatory action of prostacyclin against the ADP-induced aggregation was also observed. It is concluded that in advance atherosclerosis the platelet system is hypersensitive to biologically active metabolites of arachidonic acid.
