[Features of growth and chemical composition of various skeletal bones of albino rats as affected by x-ray and laser irradiation].

The aim of present investigation was to demonstrate the growth peculiarities of skeletal bones different types and to observe the changes in their mineral content under the influence of X-rays and laser radiation. It was found that laser radiation causes insignificant hypohydration and increase of mineral component, which was accompanied by increase of calcium and phosphates content. The bones of animals which were treated with X-rays diminish their growth in all directions, accumulate sodium, while their calcium and phosphate content was decreased.
