The aim: to conduct analysis of the accumulation and biodistribution of gold nanoparticles in the structural and functional areas of mesenteric lymph nodes of white rats conducted with regard to the size and duration of the oral administration. The methods of dark field microscopy with Leica DM 2500 microscope were used to assess biodistribution of gold nanoparticle. The histochemical reaction of silver amplification with silver lactate by Danscher was used to confirm its identification. Results: It was found that the gold nanoparticles of 1-3 nm were not detected by these methods in any of the areas of the lymph nodes regardless of the duration of administration, gold nanoparticles of sizes 15 and 50 nm were detected in the form of clusters in the cytoplasm of macrophages and lymphocytes mainly in the mantle zone of lymphoid follicles and brain strands. Conclusion: It was established that the gold nanoparticles of sizes 15 and 50 nm were detected in the form of clusters in the cytoplasm of macrophages and lymphocytes

The influence of gold nanoparticles with different size (1-3 nm, 15 nm and 50 nm) on the morphokinetics of mesenterial lymphatic node cell populations of healthy laboratory animals was investigated. It was established that the oral administration of gold nanoparticles caused the changes of morphokinetics of mesenterial lymphatic node cell populations. The morphological reorganizations in the mesenterial lymphatic nodes testified about activation of migration processes, the proliferation and differentiation processes of immunocompetent cells, which assumes the presence of immunomodulating action of gold nanoparticles.

The research goal is to investigate the influence of gold nanoparticles with different size (1-3 nm, 15 nm and 50 nm) on the morphokinetics of mesenterial lymphatic node cell populations of healthy laboratory animals. Experiment included 24 white rats. The investigation was conducted in 4 groups of animals. The animals were administered the gold nanoparticles orally for 15 days. It was established that the oral administration of gold nanoparticles caused the changes of morphokinetics of mesenterial lymphatic node cell populations. The morphological alterations in the mesenterial lymphatic nodes assisted in activation of migration processes, the proliferation and differentiation. The immu-nomodulatory action of gold nanoparticles was proved
