Abstract
Electron scanning microscopy was applied to investigate the surfaces within the human brain ventricular system in order to establish their age-related changes. The brains were studied in different age groups and in patients with senile dementia. The changes of ependymal surfaces were manifested in the loss of ependymal cell's cilia and microvilli. These changes were marked in dementia patients. Two types of age-related changes were detected in aqueductal surface ependymal cells but its lumen was never narrowed.
摘要
应用电子扫描显微镜研究人类脑室系统内的表面，以确定其与年龄相关的变化。对不同年龄组和老年痴呆症患者的大脑进行了研究。室管膜表面的变化表现为室管膜细胞纤毛和微绒毛的丧失。这些变化在痴呆症患者中很明显。在导水管表面室管膜细胞中检测到两种与年龄相关的变化，但其管腔从未变窄。
