摘要: 目的 研究羟基红花黄色素A抗心肌缺血的作用及机制。方法 采用大鼠心肌缺血及血瘀模型,观察羟基红花黄色素A的抗心肌缺血作用及对血液流变学和凝血功能的影响。结果 心肌缺血实验显示羟基红花黄色素A能明显减少心肌缺血大鼠的心肌梗死面积,显著减少血清肌酸激酶MB型(CK-MB)和乳酸脱氢酶(LDH)的产生,并可降低心肌缺血大鼠的血液黏度及血小板聚集现象,同时可以一定程度地延长凝血酶原时间(PT)及活化部分凝血活酶时间(APTT)值;血瘀实验显示羟基红花黄色素A可以降低血瘀大鼠的血液黏度,并可抑制ADP诱导的血小板聚集,同时对PT及APTT值有一定的延长作用。结论 羟基红花黄色素A可能是通过改善血液流变学及凝血功能发挥其抗心肌缺血作用。

Abstract: AIM: To investigate the protective effects of hydroxy safflower yellow A (HSYA) on myocardial ischemia. METHODS: Myocardial ischemia and blood stasis models were used to observe the effects of HSYA on myocardial ischemia, hemoreology changes and blood coagulatory function in rats. RESULTS: Myocardial ischemia experiment showed that HSYA could reduce the area of myocardial infarction, the level of serum CK-MB and LDH, and the blood viscosity and platelet aggregation had been reduced, while the values of PT and APTT had been prolonged. Blood stasis experiment showed that HSYA could reduce blood viscosity, inhibit platelet aggregation, and the values of PT and APTT had been prolonged. CONCLUSION: HSYA has protective effect on myocardial ischemia, the effect is related to improve hemorheology and blood coagulatory function.

Key words: hydroxy safflower yellow A, myocardial ischemia, blood stasis, hemorheology, blood coagulatory function
