  1. Data are displayed as mean ± standard deviation. (p < 0.05) Note, that results, obtained by thrombelastometry, show a significant increase of clot stability and shortening of coagulation times, while platelet aggregation is increased only in MAR and TRI after ADP activation, respectively in MAR after TRAP activation, but not in CYC.
