| 摘 要： | 目的：研究实验性牙移动过程中大鼠三叉神经节内甘丙肽表达的变化，探讨其与正畸疼痛缓解之间是否具有内在的联系。方法：选择雄性Wistar大鼠35只，建立正畸牙移动动物模型，将大鼠随机分为实验组与空白对照组。实验组左侧为加力侧，右侧为未加力侧，左右自身对照，分别于加力6h、12h、1、3、5、7d后处死动物，取大鼠三叉神经节，标本制备，进行免疫组织化学染色与图像分析。采用SPSSl6．0统计学软件进行统计学分析。结果：与空白对照组相比，实验组加力1d甘丙肽阳性细胞数增多，表达增强（P〈O．05）；加力3d阳性细胞数增多明显（P〈O．01）；加力5d甘丙肽免疫阳性细胞数达到高峰，神经节细胞中甘丙肽免疫阳性染色呈强阳性表达（P〈0．01）。实验组未加力侧各时间点与空白对照组之间甘丙肽表达无统计学差异。结论：GAL作为内源性镇痛物质与正畸牙移动所致牙体与牙周疼痛的缓解具有一定的内在联系。

| Abstract: | Objective:To observe the changes of galanin in ratstrigeminal during the experimental tooth movement and to study the relation between the galanin intrinsically and the relief of pain.Methods:35 male rats were selected and randomly divided into the experiment group(30rats) and the control group(5rats),and the orthodontic tooth movement model was made.The left first molar of the rats in experimental group was pulled toward mesiocclusion by a kind of spring,and the right side was not.The rats were sacrificed ... |
