摘    要: 目的 观察 liguzinediol ( 2 , 5- 二羟甲基 -3 , 6- 二甲基吡嗪)对正常 SD 大鼠心脏血流动力学的影响。 方法 将大鼠随机分为 5 组:生理盐水组,阳性对照组(磷酸二酯酶抑制剂米力农, 0.3 mg·kg-1 ), 3 个剂量组( liguzinediol 5 , 10 , 20 mg·kg-1 ),每组 10 只。采用 RM6240B/C (四道)型多道生理记录仪测量给药后大鼠心脏血流动力学指标如左心室收缩压( LVSP ),左心室终末舒张压 (LVEDP) ,左心室最大变化速率(± d<>p/d<>tmax ),左室开始收缩至左室内压上升速率峰值时间 (t-d<>p/d<>tmax) ,收缩压 (SAP) ,舒张压 (DAP) ,平均压 (MAP) ,脉压差 (MPP) 以及心率 (HR) 。 结果 静脉给药后, liguzinediol 5 , 10 , 20 mg·kg-1 使大鼠左心室 LVSP 、 +d<>p/d<>tmax 、 - d<>p/d<>tmax 、 SAP 、 MAP 、 MPP 显著增加, t-d<>p/d<>tmax 、 LVEDP 降低。 结论 liguzinediol 对正常大鼠心脏具有正性肌力作用。

Abstract:OBJECTIVE To determine the effect of liguzinediol on cardiac contractile force and blood pressure in rats. METHODS The heart contractile indices such as left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), maximal rising and falling rate of ventricular pressure (±dp/dtmax), t-dp/dtmax, systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), mean pulse pressure (MPP), heart rate (HR) were measured in Sprague-Dawley rats using a RM6240B/C four channel physiological recording instrument. The rats were randomly divided into 5 groups: Saline control group (NS), positive control group (phosphodiesterase inhibitor milrinone, 0.3 mg·kg-1), three different doses of liguzinediol groups (liguzinediol 5, 10, 20 mg·kg-1) (n=10 rats for each group). RESULTS Liguzinediol induced significant increases of LVSP, +dp/dtmax, -dp/dtmax, SAP, MAP and a significant decreases of t-dp/dtmax, LVEDP. CONCLUSION Liguzinediol produced a positive inotropic effect in rats.
Keywords:liguzinediol  milrinone  cardiac hemodynamics  positive inotropic effect on myocardium
