[The structure of the microcirculatory bed of the spinal cord in experimental injury to the cervical spine]. / Struktura mikrotsirkuliatornogo rusla spinnogo mozga pri éksperimental'noi travme sheinogo otdela pozvonochnika.

The trauma of the cervical spine was simulated under hexenal anesthesia in non in bred albino rats (100-150 g of weight). The animal was immobilized in a special stand and its head was turned to the right (by 90 degrees) and then tilted back (by 85 degrees). A phase reorganization of the spinal cord architectonics was established in the dynamics of the trauma. In the early period (up to 24 hours), monotypic diminution of the intensity of perfusion of the capillaries with Indian ink was observed with the appearance of no reflow zones, mainly in the regions of "adjacent" blood supply. Later 5-10 days after the trauma, a mosaic pattern of restoration of the perfusion level appeared, which was linked with the different conditions for normalization of the blood flow in some of the spinal cord regions.

[Blood content of the vertebrobasilar basin during experimental trauma of the cervical portion of the spine]. / O sostoianii krovenapolneniia vertebrobaziliarnogo basseina pri éksperimental'noi travme sheinogo otdela pozvonochnika.

The author measured the blood content of the vertebrobasilar bed in rats with a cervical trauma induced by backward bending and simultaneous rotation of the neck. The blood content of the vessels was found to undergo a phasic reduction at both the cerebral and spinal levels depending on the duration of the posttraumatic period. It was demonstrated that a neuro-reflectory spasm of the extracranial portion of the vertebral arteries is the cause underlying the development and evolution of the above changes in the circulation system in the given injury.
