Recent advance in experimental animal models of migraine
Abstract
偏头痛是原发性神经系统和非神经系统综合征,表现为单纯或双侧反复发作、搏动性中重度头痛,发作前可有一过性视物模糊、闪光、偏盲、偏侧肢体感觉及运动障碍、语言障碍等先兆症状,发作期常有恶心、呕吐、畏光、怕声等伴发症.偏头痛的人群发病率超过10％,目前临床上难以彻底治愈.世界卫生组织将严重偏头痛定为最致残的慢性疾病之一,其给患者和社会带来了沉重的精神和经济负担.偏头痛的发病机制尚无定论,目前较公认的理论解释为:遗传易感性所致的内源性痛觉调节系统抑制功能缺陷,在内外环境刺激下,皮质或三叉神经颈髓复合体(trigeminocer-vical complex,TCC)神经电活动异常,引起一系列神经、血管、递质改变,导致偏头痛[1].据此学说目前设计出了多种偏头痛动物模型.本文以诱导靶点为分类依据,将现有的偏头痛动物模型分类并将其原理、方法及特点综述如下. 关键词：偏头痛;模型,动物 分类号：R747.2 文献标识码：A 文章编号：1671-8925(2012)02-208-03
