摘要：

目的：观察颈舌咽神经脉冲电刺激对大鼠的电刺激反应性和电致惊厥阈的影响，阐明脉冲电刺激颈舌咽神经抗大鼠惊厥的有效性。方法：30只成年Wistar大鼠随机分为对照组、颈迷走神经电刺激组和颈舌咽神经电刺激观察组，每组各10只。对照组只行左侧颈部切开消毒处理，颈迷走神经电刺激组行左颈部迷走神经分离后脉冲电刺激，颈舌咽神经电刺激组行左颈部舌咽神经分离后脉冲电刺激。各组动物分别给予双侧耳缘电刺激，记录大鼠的电刺激反应性和电致惊厥阈。结果：与对照组比较，颈舌咽神经电刺激组大鼠嘶叫和发生强直阵挛的最小刺激电压显著提高(P<0.01)，颈舌咽神经电刺激组与颈迷走神经电刺激组比较差异无统计学意义(P>0.05)。结论：颈舌咽神经电刺激能提高大鼠的电刺激反应性和电致惊厥阈，有较好的抗惊厥作用。

Abstract:

Objective To observe the effects of electric pulse stimulation on cervical glossopharyngeal nerve on the reactivity and convulsive threshold in rat and to identify its efficiency against rat convulsion. Methods 30 rats were randomly divided into control group (n=10),cervical vagus nerve group (n=10) and cervical glossopharyngeal nerve group (n=10). The skin covering the left cervical parts were cut open and sterilized of rats in control group. The left cervical vagus/glossopharyngeal nerve was separated in vagus/glossopharyngeal nerve group respectively,then stimulated with electric pulse stimulation.The reactivity and convulsive threshold to electrostimulation in rats were recorded when the bilateral ears of the animals from different groups were stimulated by lectrostimulation. Results The smallest voltages causing braying,tetania and clonus in rats were remarkably enhanced in cervical glossopharyngeal group compared with control group (P<0.01). However,there was no significant difference of the smallest voltages when compared with cervical vagus group (P>0.05). Conclusion Electric pulse stimulation on cervical glossopharyngeal nerve may play a role in convulation control because it effectively enhances the reactivity and convulsive threshold to electrostimulation in rats.
