**5. Conclusion**

So, the evolution of living organisms on Earth was accompanied by a broadening and deepening of the utilization of chemical elements and their compounds, i.e., in fact, by diversification, improvement and complication of bioelements. This process continues today in both natural and artificial environment, if allowing for the development of biotechnology, genetic engineering and pharmacy.

In many cases in medicine, it is possible to use bioelements for maintaining organs and tissues instead of using cell cultures and tissues, because it is not always necessary or possible (including for financial reasons) to recover the function by a substance, organ or tissue, completely identical to the living one (e.g., in transplantology, orthopedics, in treatment of osteoporosis, diseases of skin, hair, etc.).

The development of bioelementology may lead to appearance of modified cells or technologies for creation of new cells which can be used for medical purposes.

On our opinion, the progress in trace element research will be due to interdisciplinary approach such as bioelementology. It needs change in educational programs for high school students of biological, chemical and physical specialties, creation of special programs for biotechnologists, medical researchers, ecologists and pharmacists. And this will demand united efforts of scientists and specialists from adjacent fields. Integration of scientific re‐ searches without division into separate parts, studied by only one of the "omics", though this will demand deeper and more global planning of scientific investigations on the basis of the multidisciplinary concept. Also, it is necessary to change the paradigm of diseases' prevention and treatment from mainly symptomatic to basics to prevent and normalize the balance of bioelements by nutrition and use of sources of bioelements in pharmacotherapy.
