摘要: 目的 观察甲基葡萄糖苷对实验性心衰猫心脏血流动力学的影响。方法 用戊巴比妥钠造成猫实验性心力衰竭动物模型,分别静脉注射甲基葡萄糖苷100mg·kg-1、200mg·kg-1,用多导生理记录仪和电磁流量计记录猫的心脏血流动力学参数。结果 甲基葡萄糖苷100mg·kg-1及200mg·kg-1均可使左心室收缩内压、左室压力变化最大速率、心排血量、心脏指数、左室作功指数和主动脉平均压显著增加,使左心室舒张末期压下降,对总外周血管阻力无显著影响;100mg·kg-1对心率无显著影响,200mg·kg-1时则使心率略加快。结论 甲基葡萄糖苷对戊巴比妥钠诱发的实验性心衰猫具有加强心肌收缩力、改善心肌顺应性和左室舒缩功能、增加心排血量、升高动脉血压的作用。

Abstract: Aim The effect of Methyl Polyg ly coside (MPG)on cardiachemody namics in experimental heart failurecats was studied.Methods Model of experimental heart failurewas establishedin anesthetized cats.MPG(100 mg·kg-1, 200 mg·kg-1, iv)was administered by intravenous infusion and cardiachemody namics parameters weremeasured by using polygraph and electromag netic f lowmeter.Results LVSP,±d p/d t max, CO, CI, LVWI and MAP wereobvio usly increased, LVEDP was decreased and TPVR was not markedly alteredin both low and high do se MPG group.HR was not obviously changedin low-dose group, butit was light ly quickenedin high-dose group.Conclusion MPG has the actions of enhancing myocardial contraction, improving my ocardial compliancyand left ventricularsy stolic and diostolic function andincreasing cardiacoutput and arterial blood pressurein heart failurecats caused by Pentobarbital sodium.These show MPG is beneficialtoreleasing heart failure.
