Abstract：
:Incubation of platelet-rich plasma (PRP) with ouabain, an inhibitor of sodium/potassium ATPase (Na+/K+ ATPase), induced a significant rise in basal platelet intracellular calcium concentration [( Ca2+]i) when measured using fura 2. Ouabain induced an enhanced aggregation response to low doses of collagen in both PRP and washed platelets loaded with aequorin. In aequorin loaded platelets this enhanced aggregation response was associated with an enhanced rise in [Ca2+]i such that the relationship between [Ca2+]i and aggregation was unchanged. As inhibition of plasma membrane Na+/K+ ATPase would lead to a raised intracellular sodium ion concentration [( Na+]i) the results suggest that in the platelet, [Na+]i can modulate [Ca2+]i and hence influence the response of platelets to stimuli such as collagen.
