| Abstract: | Detailed analysis of changes in the endothelial layer at late terms after injury revealed that in one month after cauterization with a 0,25%solution of silver nitrate the recovered epithelium was not substatially different from the initial state by most features and retained its specific properties. From the normal state itdistinguished by the cell size, their orientation with respect to the longitudinal axis ofthe vessel, but the signs characterizing the lining as a whole, such as correct arrangement of the layer, the shape of the cells, gave evidence that the endothelium had recovered retainingits specific properties as a highly sensitive system with intrinsic signs of a tissue type. A significant amount of binuclear cells at late terms as well as greater amount of nuclei with centromeres as compared with the normal state pointed out that the traces of the reactive processretained for a very long time. |
