目的:通过比较不同电针频率刺激"足三里"对胃扩张疼痛大鼠的拟痛行为学评分和下丘脑内疼痛信息物质P物质(SP)、β-内啡肽(β-EP)的影响,阐明电针防治胃扩张疼痛可能的物质基础,探讨不同电针频率的效应差异.方法:50只大鼠完全随机分成空白组、假手术组、模型组、低频电针组和高频电针组,除空白组外采用胃内植入气囊并充气40 mmHg压力造成胃扩张疼痛模型,低频(2 Hz)和高频(100 Hz)电针刺激"足三里"为施治因素,观察大鼠拟痛行为学评分,用免疫组化法检测下丘脑组织中SP、β-EP的表达.结果:低、高频电针均能明显降低胃扩张疼痛大鼠的拟疼痛行为学评分,与针前比较差异有统计学意义(P

OBJECTIVE: To observe the effect of different frequency electroacupuncture (EA) on hippocampal substance P (SP) and beta-endorphin (beta-EP) in rats with gastralgia so as to explore its underlying mechanism in preventing and relieving visceral pain. METHOD: Fifty rats were randomly divided into control, sham operation, model, low- frequency-EA and high frequency-EA groups. Gastralgia model was duplicated by gastric distension (a pressure of 40 mmHg) with a latex balloon. Low (2 Hz) and high (100 Hz) frequency EA was applied to bilateral "Zusanli (ST 36)" for 30 min. Pain score was given by usi...
