AGE CHANGES OF LATERAL CHOROID PLEXUS OF HUMAN BRAIN
The study deals with characteristics of age changes in morphological organization of lateral choroid plexus of human brain. The interrelation of a list of parameters (such as thickness of villi’s filtering zone, capillaries diameter, thickness of villi’s not filtering zone, thickening of walls of vessels, quantityof subepithelial thickenings) to the age was analyzed. The interrelation was analyzed by means of morphometric method. Neither of these parameters is interrelated significantly to the age according to the results of statistical analysis. It may be seen on the histological specimens, that choroid plexus of the same person can contain both intact villi and villi with involutory changeability’s signs. Expression of protein Ki-67 (that is the proliferation’s marker) was detected in some of choroid plexus epithelial cells. It was done by the usage of immunhistochemical method. So we consider, that the process of new villis’ growth is taken place persistently in lateral choroid plexus. It may be explained by the absence of statistically significant age-specific changeability’s signs in morphological organization of lateral choroid plexus of human brain.
