[Effect of daily and intermittent dynamic loading on appositional growth and vascularization of the femoral diaphysis of rats].
The experimental investigation performed for 5 months presents the data on the effect of daily and interval loading on periostal ontogenesis and vascularization of the compact substance layer in the femoral bone diaphysis of 75 white rats. Histological and morphological examination of the compact substance demonstrates a stimulating effect of dynamic loadings on periostal ontogenesis and vascularization of the femoral bone diaphysis of rats, however, different regime on distributing the same amount (100 h) of loading (daily work and work every other day) produces various osteogenic effect. Periostal ontogenesis on the background of better blood supply is more active at the effect of the interval dynamic loading that could be explained by a longer recovery interval.
