目的观察胃扩张和针刺大鼠四白传入信息对孤束核(NTS)神经元放电整合的影响.方法采用细胞外记录方法,先找到胃扩张相关神经元;以足阳明胃经四白穴为刺激点作为研究对象,并以同名经的地仓和内庭、手太阳小肠经的颧髎、非经非穴四白旁开点为对照,在刺激点上用手针施以捻转手法刺激30 s,在NTS寻找对来自体表刺激点有反应的胃扩张相关神经元.结果 52只大鼠共记录到104个NTS神经元放电,104个NTS神经元中与胃扩张相关的有47个.47个胃扩张相关神经元中兴奋性神经元32个,抑制性神经元15个.47个NTS胃扩张相关神经元中对来自体表刺激有反应的神经元出现比例,在针刺四白、地仓、内庭、颧髎、四白旁开点后分...

Objective To explore the efffect of acupuncturing Sibai point after rat gastric distension (GD) on neuron spikes of nucleus tractus solitarii (NTS). Methods After GD was created by injecting water into the stomaches of 52 SD rats, Sibai point of Stomach Meridian (ST) as experimental point as well as Dicang point and Neiting point of ST, Quanliao point of Small Intestine (SI) and non-acupoints as controls were respectively selected for body surface stimulation points, each acupunctured for 30 seconds with twisted manipulation. Meanwhile, extracellular recording method was used in NTS to validat...
