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 advanced atherosclerosis the platelet system is hypersensitive to biologically active metabolites of arachidonic acid. |
