作者黑报道白花景天Sedumeupatorioides Kom乙酸乙酯提取物对正常大鼠及肾型高血压大鼠具有显著降低血压作用,现就心脏血流动力学影响进行研究。 本实验应用MPU—0.5A型压力换能器记录颈动脉压,MF—27型方波电磁流量计记录主动脉血流量,记录第二导联心电图,上述各指标同步记录于RM—86型8导生理记录仪上。在麻醉兔(9只)上观察iv景天提取物17.5mg/kg对心脏血流动力学影响。实验结果如下: 1、对MAP和HR的作用:MAP给药
The authors report that the ethyl acetate extract of Sedumeupatorioides Kom has significant blood pressure lowering effect on normal rats and renal hypertensive rats, and the effects of cardiac hemodynamics are studied. In this experiment, MPU-0.5A pressure transducer was used to record the carotid artery pressure, MF- 27 type square wave electromagnetic flowmeter recorded the aortic blood flow, and the second lead electrocardiogram was recorded. The above indexes were simultaneously recorded in the RM-86 8 On the physiological recorder. The anesthetized rabbit (nine mice) was observed for cardiac hemodynamic effects of 17.5 mg/kg iv. The experimental results are as follows: 1. Effect on MAP and HR: MAP administration
