title: [Characteristics of the ependyma in various parts of the subcommissural organs in rats].
abstract: In this work the authors have researched ependyma of some parts of subcommissural organ of rats by optic microscopy. 4% formaldehyde was injected in vivo in carotid arteries. After immolation their brains were extracted together with brain meninges and embedded in celiodine. Celoidine blocks have been sliced and then coloured by Nissle's method. Horizontal and frontal brain dissections were performed with a purpose to acquire a good sight into the subcommissural organ. On the basis of optic microscopy of the examined material, numerous morphological variations in the size and appearance of subcommissural organ were determined as well as the presence of many layers of ependymal cells close to the posterior commissura.
