Ca2+ at 2mM concentration stimulates the release of saturated and unsaturated fatty acids from intact washed platelets incubated at 37°C with stirring. Aspirin at a concentration of 0.4mM inhibits both cyclo-oxygenase activity and fatty acid efflux induced by Cat+. Thus, in intact washed platelets, aspirin reduces formation of cyclo-oxygenase products by direct inhibition of the enzyme and by reducing the availability of precursor arachidonate.
