MORPHOLOGICAL CHANGES OF CEREBRAL SINUS VASCULAR PLEXUS OF WHITE RATS IN THEIR PRESENILE AGE DURING XENOGENIC SPINAL FLUID ADMINISTRATION

The article studied age-related peculiarities of morphological structure of the cerebral sinus vascular plexus of the white rats in their presenile age. There was analyzed dependence on xenogenic spinal fluid frequencies of administration with the following characteristics: animal weight, brain weight, length and width of hemispheres, cephalization coefficient, height and width of choroid ependymocytes. It was pointed that in years typical involutional changes of vascular plexus took place, while exogenic administration of xenogenic spinal fluid had positive influence on the brain biometric data and vascular plexus of cerebral sinus microscopic parameters.
