Abstract： 目的:探讨在大鼠垂体前叶中是否有白细胞介素-2(IL-2)表达,并明确其组织定位,以及卵巢切除(OVX)对其表达的影响. 方法:将大鼠分为正常对照组(NOR)、卵巢切除组(OVX)、卵巢切除+雌二醇组(OVX+E)、卵巢切除+油剂组(OVX+O)和假手术组(SO),取垂体前叶标本进行免疫组化染色,并以图像分析方法分析垂体前叶细胞中IL-2免疫阳性物质含量的变化. 结果:IL-2免疫反应阳性物质仅分布于前叶,在中叶和后叶则未见. 与正常对照组相比,OVX组和OVX+O组IL-2免疫阳性物质含量明显增多;而OVX+E组IL-2免疫阳性物质含量无明显变化. 结论:我们首次报道IL-2在大鼠垂体的组织定位,机体雌激素水平下降可明显上调其表达.
