Structural changes in osseous and cartilaginous tussues of the mandible under effects of heavy metals salts on the body

Abstract

We have studied morphological changes in the osseous and cartilaginous tissue of the lower jaw of 72 experimental male albino rats whose bodies were influenced by the salts of heavy metals. We used anatomical, osteometric, spectrophotometric, histological, histochemical, morphometric, immunomorphological and statistical methods. It is shown that heavy metals salts cause the development of deep and persistent structural changes in the osseous and cartilaginous tissues of the mandible, which is accompanied by inhibition of growth, development of resorptive processes in the osseous tissue, reduced mineralization, depletion of inorganic matrix in macroand microelements. Negative morphological changes develop in the process cartilage: zonal structure is impaired, proliferative activity of chondrocytes is inhibited.
