我们用高分子右旋糖酐Ｗｉｓｔａｒ大鼠尾静脉内注射，复制微血栓形成的大鼠动物模型，探讨微血栓对心脏、血管内膜结构的影响，其中除采用病理形态学直接观察外，还进行了循环血内皮细胞计数（ＣＥＣ）和血浆内皮素（ＥＴ），内皮舒张因子（ＥＤＲＦ／ＮＯ）含量测定，借以了
We use polymer dextran Wistar rat tail vein injection, replication rat thrombosis rat model to explore the impact of micro-thrombus on the heart, intimal structure, in addition to direct observation by pathological morphology, but also the cycle Blood cell count (CEC), plasma endothelin (ET) and endothelium-dependent relaxation factor (EDRF / NO)
