STRUCTURAL CHANGES OF THE BONE REGENERATE DURING CELLULAR DEHYDRATION

Reparative bones regeneration peculiarities under cellular dehydration were researched on aged laboratory male rats. The shin bone was fractured under cellular dehydration modeling. From the commencement of the experiment the percentage composition of regenerate cells changed. Increasing dehydration caused more changes. Further dehydration conditions resulted in disregenerative changes and tissue structure inhibition, which is evident due to the remains of the granulation tissue on the 15th day under the medium and high dehydration levels and the remains of the fibroreticular tissue ? on the 24th day under the high dehydration level. The changes were not detected in the control set of animals. These changes were confirmed with the raster electron microscopy. One can also observe the reduction of the basic chemical elements, hardness disturbance, and general growth inhibition. The result of these changes is general inhibition of callus formation.
