[Changes in the cerebral cortex in closed craniocerebral trauma of gunshot origin (experimental research)].
Cerebral cortex was studied morphologically in rabbits with concussion of brain induced by gunshot injury. The extent of severity was modelled by the bullet rate. No significant bleeding followed the injury allowing to observe the animals during the necessary terms (7-14 d.) Morphological study included light optical and electron microscopy. In neurons, glial cells and synapses a series of essential destructive changes in shown detectable predominantly on ultrastructural level that might be the base of psychoneurological complications of a distant period. Ballistic properties of a bullet were obviously fundamental to pathogenesis of brain concussion in these experiments as kinetic energy of the bullet was only sufficient for non significant damage of the skull soft tissue. But in contrast to the dull trauma, the blow was of a high speed and despite mild clinical characteristics caused essential diffuse structural disturbances in brain tissues.
