摘要: 目的:观察氧化苦参碱(OMT)对大鼠血压的影响。 方法:将48只Wistar大鼠随机分为6组(n=8),即生理盐水组,OMT 30、60和90 mg•kg-1组以及普萘洛尔加OMT 60 mg•kg-1组和多沙唑嗪加OMT 60 mg•kg-1组。常规颈动脉插管,股静脉给药,应用BL-420生物机能实验系统记录大鼠血压及心率。结果:静脉给予OMT 30、 60和 90 mg•kg-1具有剂量依赖性地降低血压的作用,OMT能增强多沙唑嗪的降压作用,但与普萘洛尔无协同降压作用。 结论:OMT的降压作用呈现剂量依赖性,且与多沙唑嗪具有协同的降压效应。

Abstract: Objective To investigate the effects of oxymatrine (OMT) on blood pressure in rats. Methods Fourty-eight Wistar rats were randomly divided into 6 groups (n=8):normal saline group,OMT groups with different doses(30,60,and 90 mg•kg-1),propranolol+OMT 60 mg•kg-1 group and doxazosin+OMT 60 mg•kg-1 group. Cannula was cannulated commonly into carotid artery and connected with BL-420 BioLab System to record the blood pressure and heart rate(HR) in rats. Results Mean arterial pressure(MAP) were significantly lower than control in dose-dependent manner after intraventous adminstration of OMT(30,60,and 90 mg•kg-1). Conclusion OMT can decrease the MAP in dose-dependent manner. OMT and doxazosin have synergetic effects on MAP.
