EFFECTIVENESS OF MESENCHYMAL STEM CELLS IN UVEITIS IN DOGS, DEPENDING ON THE METHOD OF THEIR ADMINISTRATION

Abstract

The article highlights the results of studies on spontaneous clinical cases of bacterial uveitis in dogs, using a slit lamp, sonographic and visual research methods, and after the introduction of mesenchymal stem cells in various ways. These research results make it possible to analyze and further study the effect of mesenchymal stem cells, when administered in various ways in total uveitis, and determine the most effective method in clinical cases in dogs. Chronic total uveitis is an extremely severe late complication of ophthalmic surgery, and leads to slow functional and anatomical death of the eye. The use of antibacterial drugs for the Prevention of infectious complications often smooths out the clinical picture of progressive intraocular inflammation, contributing to an increase in its latent period. All this with particular relevance indicates the need for research as early as possible, and the specifics of the use of stem cells in eye diseases in dogs. Our research on the restoration of eye tissues depends on many factors, on the balance between inflammatory mediators and their antagonists, which activate the synthesis of anti-inflammatory mediators. Also, it depends on the number of mesenchymal stem cells that act as a regulator of proliferation in damaged eye tissues and cause cyto-differentiation during cell regeneration and enhance their own antioxidant properties. It was found that microbial contamination significantly deepens the consequences of damage to tissues and structures of the eye, which lead to acidosis of tissues, changes microcirculation and exit and destruction of cell membranes and prolongation of the inflammatory phase, namely, it determines the course and results of the reparative process. At the same time, we can talk not only about the recovery function of damaged tissue structures with the help of mesenchymal stem cells, but also the effect on the intensity of the inflammatory process, which significantly reduces the time of repair of eye tissues at the level of cells and tissues. The data obtained can be used for new modern methods of treating many pathologies associated with eye tissue damage and the use of mesenchymal stem cells in reparative ophthalmology.
