[Morpho-functional changes of neurons in temporal cortex in comparison with spatial memory in bulbectomized mice after treatment with minerals and ascorbates].

The effect of antioxidant mixture of mineralascorbates (MA) on the status of neurons of brain temporal cortex and behavior of mice after olfactory bulbectomy (BE) was studied, as it was previously shown by us that these animals were characterized by a deficit of spatial memory and development of neurodegenerative process in brain structures, which are affected by Alzheimer disease. Disorganization of cytoarchitectonics of temporal cortex with the deletion of its layers as a result of dystrophy of pyramidal neurons and foci of their complete disappearance were shown 1 month after BE. The increased number of neurons with the phenomena of karyopyknosis, karyolysis and vacuolysis was observed with a concomitant reduction in neuronal density. Addition of MA to the diet for three weeks prevented the development of deterioration of spatial memory in mice after BE and protected the neurons of brain temporal cortex from the degenerative changes. The results obtained suggest the possibility of realization of prophylaxis aimed at the prevention of the development of Alzheimer-type neurodestructive processes.
