Abstract:
The Ca, Cl, Mg, Na, and P contents and Ca/P, Ca/Mg, Ca/Na, Cl/Ca, and Cl/Na ratios in samples of intact bone, inflamed bone, and Ewing's sarcoma tissue were investigated by neutron activation analysis with high-resolution spectrometry of short-lived radionuclides. In Ewing's sarcoma tissue, the mass fractions of Cl and Na are higher and the mass fractions of Ca and Mg are lower than those of both normal and inflamed bone tissues. It was shown that the levels of Ca and Cl mass fractions and also levels of the Ca/Cl and Cl/Na ratios can be used as an additional test for differential diagnosis between inflamed (or normal) bone and Ewing's sarcoma.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
