Abstract
Introduction. Based on arabinogalactan, a complex of hybrid nanobiocomposites has been created, which carry a balanced amount of macro- and microelements necessary for the body. A feature of the action of nanoparticles on the body is their ability to easily penetrate all organs and tissues. The aim of the work is to study the effect of copper arabinogalactan on the content of copper in the main tissues and organs of rats. Material and methods. The content of copper in organs and tissues of rats after a 10-day intragastric administration of a solution of copper arabinogalactan in a dose of 500 μg per kg of weight was studied by the atomic absorption method. Results. A high level of copper (above 2 μg/g) was found in wool, kidneys, liver, and heart. The brain and testes contain from 1 to 2 μg/g of copper. In the tissues of the stomach, small and large intestines, thymus, pancreas, blood, eyes, spleen, lungs, and skeletal muscles - less than 1 μg/g. Conclusion. The study of the distribution of copper in the organs of rats after oral administration of the nanocomposite of copper oxide with arabinogalactan demonstrated the main target organs for the accumulation of the element to be the kidneys, liver, brain, and stomach. The different character of the accumulation of copper in the tissues of the body of the rats received arabinogalactan of copper in the form of a nanocomposite, may indicate the selective ability of tissues and organs to accumulate this element. For further work on the possible use of the drug for medicinal purposes, it is necessary to take into account the peculiarities of biodistribution and bioaccumulation in various organs.
