[Morphofunctional evaluation of the condition of the brain in rats with different degrees of recovery of neurological status following arrest of systemic blood circulation].
The brain status was studied for four days after resuscitation of rats with different degrees of recovery of the neurological status after systemic circulatory arrest induced by the occlusion of vascular bundles of the heart. Morphometric analysis of the population of Purkinje cells from the two different functional zones of the cerebellum revealed that in comparison with completely recovered rats, the animals with disturbed neurological status were characterized by loss of neurons, disturbed composition of the neuronal population, development of severe dystrophic cell changes. The lateral zone of the cerebellum hemisphere was most affected. Four days after resuscitation all the animals showed a sharp increase in the size of the nucleus of Purkinje cells, which is considered to be one of the mechanisms of neuronal adaptation to hypoxia.
