  • Title: [Comparative study of the effect of weightlessness and artificial gravity on the density, ash, calcium, and phosphorus content of calcified tissues].
    Author: Prokhonchukov AA, Komissarova NA, Zhizhina NA, Volozhin AI.
    Journal: Kosm Biol Aviakosm Med; 1980; 14(4):23-6. PubMed ID: 7421095.
    Abstract:
    The studies were carried out on 30 rats flow for about 19 days aboard the biosatellite Cosmos-936 (5 centrifuged rats including) and 25 ground-based control rats. Postflight the centrifuged rats did not show significant differences in the density, mineral saturation, distribution of vascular channels in bones, ash, calcium and phosphorus content in skeletal bones and teeth as compared with the parameters in synchronous and vivarium controls. In the weightless rats these values were significantly lowered.
