摘    要:目的观察重组线虫抗凝蛋白rAcaNAP9抗大鼠颈总动脉血栓的效果。方法将40只SD大鼠随机分为rAcaNAP9低剂量组(40μg/kg)、中剂量组(200μg/kg)、高剂量组(1 mg/kg)、阳性药对照组(肝素钠,1650 U/kg)和模型对照组共5组,每组8只。分离大鼠一侧颈总动脉,从鼠尾静脉给药后,即用血栓生成仪对动脉进行恒流电刺激5min,检测受刺激血管的堵塞程度。结果模型对照组的血管堵塞程度和rAcaNAP9低、中、高3个剂量组比较差异均有统计学意义(P〈0.05或0.01)。结论重组线虫抗凝蛋白rAcaNAP9具有抗大鼠颈总动脉血栓效果。

Abstract:Objective To investigate the antithrombotic role of recombinant nematode anticoagulant protein rAcaNAP9 in rat's common carotid artery(CCA).Methods Forty rats were randomly divided into model control group,positive drug group(heparin,1650 U/kg),and low-(40 μg/kg),middle-(200 μg/kg) and high-dose(1 mg/kg) rAcaNAP9 groups.After isolation of unilateral CCA and intravenous injection of various drugs through caudal vein,the CCA was stimulated by a constant current for 5 minutes and its blood flow volume was recorded.Results The blood flow volume in 3 rAcaNAP9 groups was superior to that in model control group(P〈0.01 or 〈0.05).Conclusion The rAcaNAP9 has the antithrombotic effect on rat's CCA.
Keywords:rAcaNAP9
