Antiplatelet and Antithrombotic Effects of Epimedium koreanum Nakai

Figure 2

E. koreanum inhibits (Ca2+)i mobilization and reduces ATP release and TxB2 production. (a) Fura 2/AM-loaded rat platelets (3 × 108 cells/mL) pre-treated with vehicle or different concentration of EAF and stimulated with collagen (2.5 μg/mL) for 3 min. Assessment of ATP concentration (b) and thromboxane-B2 production (c) was done in a supernatant of stimulated washed platelets (3 × 108 cells/mL) suspension pre-treated with vehicle or various EAF concentrations and stimulated with collagen for 5 min on a luminometer or TxB2 ELISA kit, respectively. Results are represented as mean ± SD values from at least four independent experiments. and versus control. R: resting; C: control.
