摘要:
obvocy objective:abvory: (ea)在田(ST25)和shangjuxu(st37)组合中。
方法: visc的模型通过结直肠延伸(CRD)刺激诱导IBS中的ER肌超敏反应。清洁级男性Sprague-Dawley(SD)大鼠被随机分为四组:正常组(NG),模型组(MG),电针仪组(EA)和神经胶质细胞抑制剂组(FCA)。 Bilateral EA (2/100 Hz, 1 mA, 30 min) was administered at the Tianshu (ST25) and Shangjuxu (ST37) in week 6. Abdominal withdrawal reflex (AWR) scores were used to assess the behavioral response associated with visceral hyperalgesia, while hematoxylin-eosin staining was employed to evaluate pathological changes in the colon.使用免疫荧光,免疫 - 组织化学,蛋白质印迹,实时聚合酶链反应分析了结肠和结肠相关背根神经节(DRG)中神经纤维纤维酸性蛋白(GFAP)的蛋白质和mRNA水平。通过全细胞贴片夹分析观察到EA对结肠相关DRG神经元的电生理特性的影响。
结果: ea显着降低了IBS大鼠的内脏疼痛行为得分,响应于分级(20、40、40、60、80 mm Hg)CRD刺激。此外,EA下调了与IBS大鼠结肠和结肠相关的DRG中GFAP的蛋白质和mRNA表达水平。 EA also regulated the resting membrane potential, rheobase and action potential of colon-related DRG neurons in rats with IBS.
CONCLUSIONS: EA can regulate the excitatory properties of colon-related DRG neurons by downregulating the protein and mRNA expression of GFAP in the colon and与结肠相关的DRG,表明具有潜在的神经生物学机制,通过IBS,EA可以缓解大鼠内脏超敏反应。
