[Histological aspects of posttraumatic regeneration].
A number of histological aspects (regeneration capacity, origins of regeneration, means of reparation) are discussed on the example of the reparative regeneration of the adrenal cortex. The adrenal cortex is found to possess high regeneration capacity after a traumatic injury of the organ. Realization of this capacity is dependent on general and local conditions, the character and the volume of the injury and the degree of involvment of cambial zones being of substantial significance. Among these zones are the glomerular zone and the external part of the bundle zone, whose proliferating cells are the source of the reparative regeneration of the cortical substance. The reparation of the functioning mass of the adrenal cortex is performed by the type of regenerative hypertrophy or the reparative regeneration depending on the character of the trauma. After the first type, the division of cells and their differentiation occur within the limits of the available structural elements, after the second type- of the newly formed ones. Both types are evolutionally conditioned and are definitely similar eather to postnatal growth and physiological regeneration (regenerative hypertrophy), or to the embryonic histogenesis of the definitive adrenal cortex (reparative regeneration).
