脑和脊髓终生浸浴于一种液体 ,即脑脊液中。脉络丛位于第Ⅲ、Ⅳ及侧脑室内 ,一般认为是脑脊液产生的主要场所 ,也是血 脑脊液屏障的部位所在。有关脉络丛超微结构的研究 ,国外已有一些报道[1,2 ] ,但国内尚少见。本文利用扫描和透射电子显微镜观察法 ,对大鼠侧脑室脉络丛的超 The brain and spinal cord is immersed in a fluid, the cerebrospinal fluid, for life. Choroid plexus is located in Ⅲ, Ⅳ and lateral ventricle, is generally believed to be the main place of cerebrospinal fluid, but also the site of blood-brain spinal fluid barrier. Choroid plexus ultrastructure study abroad, there have been some reports [1,2], but the domestic is still rare. In this paper, the use of scanning and transmission electron microscopy of rat ventricular choroids plexus super
