Methods60 SD rats were divided into 6 groups at random by SAS, the rats were pretreated with  drug or 0.3％CMC by lavage respectively according to the regulation， soaked   after injection s.c with 0.08mg/100g adrenine into ice water for 5min to prepare rat model of acute blood stasis. Then the parameters of hemorheology  and platelet aggregation were determined. ResultsThe XSJZW groups could obviously decrease the levels of blood viscosity high 、low shears , blood reduce viscosity high 、low shears,  hematocrit , index of erythrocyte aggregation , fibrinogen(P<0.01 or P<0.05),and increase those of index of erythrocyte deformability (P<0.05), inhibit platelet aggregation，improve some parameters, XSJZW groups were better than FFDSP(P<0.05),the dosedependence was observed among the XSJZW groups. ConclusionThe XSJZW groups can significantly improve hemorheology and hypercoagulabale state of blood and inhibit platelet aggregation in acute bloodstasis model rats， and is beneficial to prevent and treat the development of coronary artery disease and its complications.  　　Key words：XSJZW；  Acute Blood Stasis Model；  Hemorheology;  Platelet Aggregation     　　消栓降脂丸是我院方剂，临床应用十余年来，其对高血脂症、动脉粥样硬化、冠心病、脑中风等心血管性疾病有很好的预防治疗作用［1］。卢大雷等［2］曾观察了消栓降脂丸对TIA病人血小板活化功能及血浆纤溶酶活性的影响，我们报道过其对高脂血症大鼠血液流变学的影响［3］ 。本研究进一步探讨消栓降脂丸对急性血淤模型大鼠血液流变学和血小板聚集的影响。　　1  材料与方法　　1.1  材料　　1.1.1  药品与试剂 消栓降脂丸（XSJZW），规格：90 g/瓶，每克相当于原药材0.9 g，开封市医学科学研究所制剂，制剂证号：豫药制字Z04020146，批号：200503017；复方丹参片(FFDSP)：60片/瓶，每片重0.26 g，辽宁好护士药业(集团)有限公司； CMC（羧甲基纤维素），文安县富尔纤维素厂；盐酸肾上腺素注射液：1 mg/ml，长春大政国际经贸（集团）制药有限责任公司。
