方法比浊法测定大鼠血小板聚集活性、荧光光度法测定血小板5 - HT释放反应、分光光度法测定血浆NO含量、血液流变全自动分析仪检测血液流变性。
Methods Platelet aggregation was quantified by turbidimetry, release of 5 HT was assayed by fluorescence technique, and content of NO in plasma was determined by spectrophotometry.
结论：909能预防大鼠脑缺血所致脑损伤、抑制静脉血栓形成，并能够改善血液流变性和抑制血小板聚集。
Conclution: The 909 can improve cerebral ischemia and inhibit deep venous thrombosis, and it also could improve property of hemorheology and inhibit platelet aggregation.
结论心肌缺血再灌注损伤对血流变性和血小板有明显影响，导致微循环出现障碍。
Conclusion Hemorheoloical and platelet index has marked change in the animal with myocardial ischemic reperfusion injury. Microcirculation and hemorheology occurred disturbance.
