目的:探讨四白穴针刺效应的传入途径.方法:SD大鼠36只,随机分成空白组、假手术组、辣椒素组、溶媒组、电针"四白"穴+辣椒素组、电针"四白"穴+溶媒组.游离一侧眶下神经,辣椒素组将浸泡有1.5%辣椒素的棉条包绕在眶下神经上.溶媒组用浸泡在溶媒中的棉条包绕在眶下神经上.采用免疫组化技术观察三叉神经脊束核尾侧亚核(cSTN)的c-fos表达.结果:空白组在cSTN各层可见到零星、散在的阳性细胞.溶媒组、辣椒素组以及假手术组cSTN的c-fos阳性细胞数与空白组相似.电针"四白"穴+溶媒组c-fos在cSTN内主要集中在浅层(Ⅰ-Ⅱ层),其阳性细胞的数量明显多于其余各组(P

OBJECTIVE: To explore the afferent pathway of signals from electroacupuncture (EA) at "Sibai" (ST 2) acupoint. METHODS: A total of 36 SD rats were randomly divided into control, sham operation (sham), capsaicin, vehicle, capsaicin + EA, and vehicle + EA groups, with 6 cases in each. EA (1/20 Hz, 1-3 mA) was applied to "Sibai" (ST 2). After anesthesia (10% urethane), unilateral infraorbital nerve was separated to be immersed in a 1.5% capsaicin-fluid-soaked cotton ball for lesion of C fibers. Vehicle (20% tween) was used to immerse infraorbital nerve for vehicle and vechile + EA groups. The exp...
