目的：探讨生理状态下猫内囊组织间隙在纤维束间隙内的引流方向。方法：将 ５ｕｌ印度墨汁０．４ ｕｌ／ｍｉｎ的速度立体定位地注射于猫内囊．在脑切面、２ ｍｍ透明脑薄片及石蜡切片上对碳颗粒的扩散和引流途径予以观察。结果：脑切面及透明后的脑薄片显示，墨汁在三个平面上均沿白质扩散；脑室外侧壁轻微黑染．光镜下，墨汁从脑内注射点沿白质纤维网向脑室方向扩散。脑室管膜下，碳颗粒成簇呈线状排列．结论：猫内囊组织间液经纤维束间隙弥散到脑室管膜下区，由此可能引流入脑室。
OBJECTIVE: To investigate the drainage direction of internal cat tissue cyst in the interspace of cats under physiological conditions. Methods: 5ul Indian ink 0.4 ul / min speed stereotaxic injection of cat inner capsule. Diffusion and drainage of carbon particles were observed in brain sections, 2 mm clear brain slices and paraffin sections. Results: Brain slices and transparent brain slices showed that the ink spread along white matter in all three planes; slight black staining of the lateral ventricle walls. Light microscope, the ink from the brain injection point along the white matter fiber network to the ventricle direction. Subependyma, carbon particles clustered in a linear arrangement. Conclusion: Cats interstitial fluid interspersed into the subventricular zone through the fiber bundle interspace, which may drain into the ventricle.
