为了研究HMG Co A还原酶抑制剂是否抑制体内血栓形成,我们研究了西伐他汀对大鼠颈动脉血栓模型、大鼠血小板活化和大鼠凝血-纤溶系统的影响。西伐他汀显著抑制体内血栓形成。克伐他汀还显著降低血小板聚集和血小板表面p -选择素诱导的ADP表达,提示克伐他汀抑制血小板活化。西伐他汀不影响大鼠血浆纤维蛋白原、组织因子、组织纤溶酶原激活因子和组织纤溶酶原激活因子抑制因子水平,提示西伐他汀不影响大鼠凝纤溶系统。因此,HMG Co A还原酶抑制剂可能通过降低血小板激活来抑制体内血栓形成。
英文摘要
To investigate whether HMG Co A reductase inhibitor inhibits in-vivo thrombus formation, we studied the effects of cerivastatin on rat carotid artery thrombus model, rat platelet activation and rat coagulation-fibrinolysis system. Cerivastatin significantly inhibited in-vivo thrombus formation. Crivastatin also significantly decreased platelet aggregation and platelet surface expression of P-selectin induced ADP, suggesting that cerivastatin inhibits platelet activation. Cerivastatin didn't affect rat plasma levels of fibrinogen, tissue factor, tissue palsminogen activating factor and tissue plasminogen activator inhibitory factor, suggesting that cerivastatin didn't affect rat coagulation-fibrinolysis system. Thus, HMG Co A reductase inhibitor may inhibit in-vivo thrombus formation by decreasing platelet activation.
