Figure 1. Platelet aggregation and ATP release. Washed human platelets were treated with salidroside (0, 5, 10 and 20 μM) at 37°C for 1 h and platelet aggregation and ATP release was measured after stimulation with thrombin (0.03 U/ml) (A) or CRP (1 μg/ml) (B) in a Lumi-Aggregometer. Meanwhile, P-selectin expression was measured by flow cytometry (C). Data were presented as mean ± SE (n=4-6) and analyzed by one-way ANOVA. Compared to 0, *P < 0.05; **P < 0.01; ***P < 0.001.
