Platelet P-selectin expression and aIIbb3 activation. After PD treatment, human platelets were stimulated with collagen (10 μg/ml) or ADP 10 (μM) followed by measuring platelet surface P-selectin expression by flow cytometry using PE-conjugated anti-P-selectin antibody and FITC-conjugated PAC-1 antibody (mean ± SD, n = 3). Compared with 0, *P < 0.05; **P < 0.01; ***P < 0.001
