MORPHOLOGICAL CHANGES IN CYTO-ANGIO-ARCHITECTONIC OF MAMMILLARY BODIES IN HUMANS, DEPENDING ON AGE AND SEX
The analysis of age-related changes in mammillary bodies cytoarchitectonic can note their similar dynamics in both gender groups. At the same time of onset and severity of changes in their average values depend on sex. It should be noted that the strength of correlation with the parameters being studied in different age sex groups is different. In general we can say that the changes occurring in the ratio of neuron-glio-capillary in mammillary bodies of men, differ from similar processes in the female group, with less powerful correlation of age. The most pronounced sex differences of the morphology of the mammillary bodies nuclei were found in the second period of adulthood. In humans of both sexes with age, in comparison with youthful period, it is noticed the increase in the number of glial cells and reducing the number of microvessels, which is accompanied by involution of neurons and their death. In the male group with age revealed a significant increase in the number of glial cells by 43.9% and glio-vascular index 79.2%, while reducing the number of neurons by 39% and 57.6% of microvessels. The women noted similar dynamics, but is it more pronounced. With age, a women´s group increases the number of glial cells by 59.2%, increasing the value of the index glio-vascular to 84.2%. It is accompanied by a decrease in the number of neurons and microvessels in the nuclei of mastoid bodies by 30.2% and 57.7% respectively. The most pronounced relationship between the observed sex groups on indicators of glial index, can be explained from the positions that the rate of the average number of glial and nerve cells also have a significant correlation. There is also a correlation, but of weak force (0.16) mean values of the area of the nuclei of neurons.
