麻醉犬静脉注射绞股蓝总皂甙(GPs)20mg/kg后,体动脉压与肺动脉压显著降低,心率显著减慢,心输出量、心阻抗微分图Cdz/dtmax及Heather指数呈降低趋势,射血前期呈延长趋势。体血管阻力与肺血管阻力、左心室射血时间及血浆血管紧张素Ⅰ与血管紧张素Ⅱ浓度等无显著变化。结果提示,GPs在该浓度下静脉注射可能对犬心功能有抑制作用,体动脉压与肺动脉压的降低可能与之有关。
After anesthetized dogs were injected with 20 mg/kg of GPs, the arterial pressure and pulmonary arterial pressure decreased significantly, the heart rate decreased significantly, and the cardiac output, Cdz/dtmax, and Heather index showed a decreasing trend. Prolonged trend. There was no significant change in body vascular resistance and pulmonary vascular resistance, left ventricular ejection time, and plasma angiotensin I and angiotensin II concentrations. The results suggest that intravenous injection of GPs at this concentration may have an inhibitory effect on heart function in dogs, and a decrease in arterial pressure and pulmonary arterial pressure may be related to it.
