目的:观察延髓孤束核P物质免疫阳性反应产物的分布以及针刺"足三里"穴对其的影响.方法:将SD大鼠随机分为三组:电针"足三里"穴组(n=10)、电针"足三里"穴旁开0.5 cm组(n=10)、空白对照组(n=10).应用免疫组织化学ABC法显示延脑组织SP免疫活性切片.结果:孤束核内P物质的免疫阳性反应产物以膨体型纤维为主,呈点状和串珠状,其敞开部有少量阳性胞体.主要分布于孤束核的内侧亚核、连合亚核,其余亚核内较为稀疏;电针"足三里"穴内侧亚核、连合亚核阳性纤维的光密度明显升高,其余亚核无明显变化;电针"足三里"穴外侧旁开0.5 cm组与空白组相似,各亚核均无明显变化.结论:针刺"足三里"可能通过抑制NTS内侧亚核和...

Objective: To observe the distribution of substance P like immunoreactivity(SP LI) in the nucleus of solitary tract(NTS)and the effect of electroacupuncture(EA) at 'Zusanli' (ST 36) on SP. Methods: Thirty SD rats were randomly and evenly divided into control group, 'Zusnali' group and Non acupoint (about 0.5 cm beside 'Zusali') group. EA (sparse dense waves, frequency of 16～ 20 Hz and strength that is able to induce slight muscular tremor) was applied to bilateral 'Zusanli' (ST 36) for 20 min.Avidin biotin peroxidase complex (ABC) method of im...
