[Calcium and phosphorus content and the 45Ca incorporation into the bones and teeth of rats after a 22-day orbital space flight on board the "Cosmos-605" satellite ship].
Examinations of 37 rats flow for 22 days onboard the biosatellite Cosmos-605 revealed no changes in the mineralization coefficient or the Ca and P content in humerus and teeth of the animals on the 2nd and 26th postflight days. Radioisotope studies showed changes in the specific activity of Ca45 incorporation in humerus and incisors. In flight rats the parameter decreased by 37-44%, in synchroneous animals it increased by 102% in bones and by 20% in incisors as compared with the vivarium controls on the 2nd postflight day. The specific activity of Ca45 incorporation was 92.7% in humerus and 44.2% in incisors of flight rats and 72.9% in humerus and 94.7% in incisors of synchroneous rats as compared with the vivarium controls on the 26th postflight day.
