title: [The mechanisms of reparative regeneration of venous endothelium].
abstract: The reaction of endothelial cells of the inferior vena cava in response to freezing-induced lesions has been analysed in the experiments on 34 young adult Kyoto-Wistar normotensive rats. First the de-endothelialized surface is covered with flattened platelets and then, three days after surgery, the endothelium is restored as a result of migration and proliferation of endotheliocytes. The migrating endothelial cells removed the adhered platelets from de-endothelialized surface. The young endothelium was presented by a single layer of strongly elongated endothelial cells whose axis was parallel to the flow of blood. An immature endothelium is characterized by an increased number of endotheliocytes. No essential differences in the reaction of venous and aortic endothelium have been revealed in response to freezing-induced lesions.
