摘要: 目的 通过电刺激迷走神经后发射性引起交感神经的持续兴奋,建立一种新型应激性心肌病(SIC)家兔模型。方法 选用2月龄雌性新西兰白兔10只,随机分为对照组和实验组,实验组兔暴露迷走神经后利用电刺激法建立的SIC模型,并通过心电图、心脏解剖和心肌组织病理学观察进行评价,对照组只暴露迷走神经,不进行电刺激。结果 成功暴露兔迷走神经并电刺激后,与对照组相比,实验组兔1 d后心电图观察显示心率增快; 1个月后心尖部心肌变薄(0.83±0.12 mm vs 1.55±0.11 mm,P<0.05); 心肌组织出现典型的SIC心肌改变。结论 利用电刺激迷走神经可以成功建立SIC兔模型。

Abstract: Objective To establish the stress induced cardiomyopathy (SIC) model in rabbit via the stimulation of vagus nerve by using electricity signal. Methods Ten femaleNew Zealand White rabbits at the age of 2 months were randomly divided into control group and experimental group. The vagus nerve of the experimental group rabbits were exposured and stimulated intermittently by using electrical signal. The rabbit model were evaluated by electrocardiogram (ECG), necropsy and pathological observation of myocardial tissue. Results The ECG at 1 day after operation showed that heart rate of rabbit in experimental group was faster than that of the control group. Meanwhile, apical myocardial in the experimental group became significant thinner than that in control group at one month after operation(0.83±0.12 mm vs 1.55±0.11 mm, P<0.05). In addition, myocardial tissue of rabbits in experimental group were showed typical changes of stress induced cardiomyopathy. Conclusion The SIC rabbit model can be successfully established via stimulating the vagus nerve by using electricity signal.
