Abstract: During the conducted research, it is established that aluminium chloride intoxication leads to the considerable changes of composition of red blood, development of a hypercalcemia and change of a bone structure of animals. A number of significant morphofunctional changes in the hippocampus of the examined animals are also noted. The use of the tissue preparation “Nicavet-1000” leads to the normalization of both hematocrit and other parameters of red blood, as well as to the intensification of erythropoiesis. Use of the preparation “Nicavet-1000”, judging from the results of research, prevents pathological changes in a bone tissue, caused by aluminium chloride. “Nicavet-1000” leads to the expressed normalization of both the morphological, and micromorphometric parameters characterizing a hippocampus of rats.
