本文用方波电磁流量计和多导记录仪同步观测了抗栓酶-3号对乌拉坦麻醉猫冠状窦血流量及某些心血管指标的影响。结果表明:静脉注射该药0.05μ/kg时能使冠状窦血流量增加15.33%(P<0.05);同时对血压、脉压、心率及ECG指标无明显影响。随剂量加大,该药能降低血压及脉压。
In this paper, the effects of antithrombotic enzyme-3 on the coronary sinus blood flow and certain cardiovascular indexes in anesthetized cats were observed with square-wave electromagnetic flowmeter and multi-guide recorder. The results showed that intravenous administration of the drug 0.05μ/kg could increase the coronary sinus blood flow by 15.33% (P<0.05); meanwhile, it had no significant effect on blood pressure, pulse pressure, heart rate and ECG index. As the dose increases, the drug can lower blood pressure and pulse pressure.
