The results of the microscopic studies

The Central nervous system. In experimental animals with hypervitaminosis D in mild cerebral membranes crust of the oblong brain hemispheres, cerebellum and spinal cord noted the growing plethora of advanced venous vessels. Space around most of the vessels of any Department of the brain and spinal cord expanded, often filled released from vessels erythrocytes (prediabetes hemorrhage). Seats were determined concentrations of glial cells, which form nodules. Chromatopelma matter of some giant cells Betz, retinal multipolar cells of the optic hill, oblong and spinal cord loose and pulverized. These cells are often extended, diffuse and homogeneous colored in light blue color. Cell nuclei are often increased, and the borders are not always clear. In some cells kernel bad differed in them or not was determined the nucleoli. However, it was discovered neurons with more intensive colouring and thickening chromatopelma substances. Single neurons of the brain had vacuoles.
Described histological pattern of the Central nervous system when hypervitaminosis D indicates degenerative changes in nerve cells. This is manifested their swelling, muddy protein dystrophy, peripheral chromatolysis and perivascular edema, venous plethora and productive cellular reaction with the formation of nodules from microglial elements.
