Figure 1. Maximal intensity and velocity of platelet aggregation induced by 5 micro Meter adenosine diphosphate (ADP; line A), 2.5 micro Meter ADP (line B), and collagen (COLL; line C) and maximal intensity and velocity of platelet agglutination induced by ristocetin (RIST; line D) in patient 4 at control (left) and 30 min after 3 ppm of nitric oxide exposure (right). CH NO = channel corresponding to each agonist; CONC = concentration of the agonist; MAX % = maximal intensity of platelet aggregation and agglutination; MAX TIME = time necessary to reach maximal intensity; PPP = optical density of the platelet poor plasma; PRP = optical density of the platelet rich plasma; REAG = agonist; SLP1 = velocity of platelet aggregation and agglutination.
