[Radiation effects on calcium concentration in mice jaws and teeth after administration of whole-body doses of 10 GY].
The investigation concerned sex-mature C57Black male mice. The animals were subjected to whole-body doses of 10 GY. At the same time the bone-marrow transplantation and local application of superoxide-dismutase (SOD) and amino-fluoride (AF) were performed. Calcium concentration in mice jaws and teeth was examined by atomic photospectrometric method. The following results were obtained: GROUP OF X-RAYED MOUSES sacrificed on the 4th day -- 21.17%Ca sacrificed on the 7th day -- 22.01%Ca sacrificed on the 10th day -- 22.45%Ca sacrificed on the 12th day -- 22.51%Ca sacrificed on the 16th day -- 18.50%Ca GROUP OF X-RAYED AND PROTECTED MICE sacrificed on the 5th day AF--21.91; SOD--22.38; AF+SOD--21.55%Ca sacrificed on the 11th day AF--21.55; SOD--20.73; AF+SOD--22.71%Ca sacrificed on the 17th day AF--22.25; SOD--22.94; AF+SOD--21.95%Ca The obtained results showed insignificant differences within the single groups. In the group of X-rayed mice a small and continual increase of calcium concentration from the 4th to the 12th day of sacrifice was evident. Thereafter the calcium concentration suddenly decreased (from 22.51 to 18.50) This did not occur in the group of X-rayed and protected animals. Values of calcium concentration in the control group were similar to those in the other group (22.81).
