摘要: 目的:观察蒺藜皂苷(GSTT)对麻醉开胸犬血流动力学和氧代谢的影响。方法:实验犬30只随机分为5组(每组6只):生理盐水对照组、血塞通(阳性对照药物)组及GSTT低、中、高剂量(6.26、12.52和25.00 mg·kg-1)组。采用静脉注射给药方式,检测血流动力学和氧代谢各项指标。结果:GSTT低、中及高剂量组犬心肌血流量高于对照组(P<0.01),平均动脉压、冠脉阻力、总外周血管阻力低于对照组(P<0.05或P<0.01),心肌耗氧量、心肌耗氧指数及心肌氧摄取率低于对照组(P<0.05或P<0.01)。 结论:GSTT对麻醉开胸犬心脏功能有明显的调节和改善作用。 

Abstract: Objective To observe the effet of gross saponin of tribulus terrestris(GSTT) on hemodynamics and oxygen metabolism in anesthetic thoraco-opened dogs. Methods Thirty dogs were randomly divided into negative control, positive control, and experimental groups(GSTT of 6.26,12.52, and 25.00 mg·kg-1)(n=6). The administration of intravenous injection was used. The effects of GSTT on the indexes of the hemodynamics and oxygen metabolism in anesthetic thoraco-opened dogs were observed. Results Compared with controls GSTT increased myocardial blood flow (CBF)(P<0.01), decreased mean arterial blood pressure (MBA), cornary resistance(CR) and total peripheral vascular resistance (TPVR)(P<0.05 or P<0.01), reduced the content and index of oxygen consumption of myocardium (P<0.01) and myocardial oxygen uptake rate(P<0.01). Conclusion GSTT can significantly accommodate and ameliorate the heart function of anesthetic thoraco-opened dogs.
