title: [Impedance testing of compact bone tissue in hypokinetic rats].
abstract: The bioelectrical impedance method was used for determination of compact bone status in white rats after 28th days of strong hypokinesia. It was shown that the lowering of mechanical loading leads to disturbances in dielectric properties and changes in electrical impedance parameters. These disturbances had different direction and manifestation. It was distinguished the two typical variants of bone dielectric properties changes. The first variant was more characteristic for early stages of hypokinetic osteodestruction, the second variant was more characteristic for the fully development hypokinetic disturbances. It was determine a correlation between the changes in electrical impedance parameters and mane components of bone matrix. The results of this study show that hyperhydratation of bone tissue play important role in hypokinetic changes of bone dielectric properties. Electroimpedance method may be used for early diagnostic of bone state in clinic and experiments.
