    ABSTRACT. The aim: To define the degree for glial acidic fibrillary protein expression on the structural components of cerebellum of the rats in health and when rats influenced by the food additives complex. Materials and methods: In order to determine the degree of expression of the immunohistochemical marker GFAP on the structural components of the cerebellum of rats we applied immunohistochemical, morphometric and statistical methods in our study. Results: In histological specimens at the end of 1st week of observation in the gray matter of the cerebellum there occurred a gradual increase in 1.16 times of the average number of GFAP-positive cells. At the end of 4th week of the experimental study, the average number of GFAP-positive cells increased accurately (at p<0.05 compared to the control group) in 1.27 times, at the end of 8th week it has increased in 1.99 times, at the end of 12th week in 2.25, and at the end of 16th week in 2.39 times. Conclusions: The outcomes of our study are as follows the increase in the average number of GFAP-positive cells is directly related to the decrease in the average number of major neurons of the gray matter of the brain, while the fluctuations in the average number of astrocytic glia cells represent a compensatory mechanism in the recovery of gray matter neurons of the brain from neural stem cells with the subsequent development of reactive astrogliosis and, thereafter the possible development of neuropathology.
