An Improved Experimental Myocardial Ischemia Reperfusion in Rat Model / 浙江中医药大学学报

ABSTRACT

[Objective] To improve the way of establishing myocardial ischemia reperfusion rat model.[Methods]30 SD rats,quality(220?20)g,male,randomly split into normal model group and improved model group,improved established model ligation with a 0.6mm diameter line,and drawn after 30min.Compare such a method with normal model.[Results] In the context of keeping experimental stability,the reduced heart rate,wake time and survival rate of the way of improved established model respectively are(50?20)/min,(15?5)min,86.67%,but it is just(120?20)/min,(80?20)min,66.67% of the normal model group.[Conclusion]The improved myocardial ischemia reperfusion model offers significant superiority to the former one.
