Quality indicators of hymatomelanic acids preparation as a potential anti-rheumatoid agent

The article studies the influence of hymatomelanic acids, one of the fractions of humic substances of peloids, on the course of rheumatoid arthritis. This substance was standardized by using physicochemical analysis. The elemental composition of the substance as well as a number of spectral (IR, NMR) characteristics were revealed. The list of components formed as a result of hydrolysis of the initial preparation and their relative content was determined. Fatty acids and their derivatives are the predominant constituents of peloid hymatomelanic acid hydrolyzate. The tissues of immunocompetent organs including regional lymph nodes, spleen, and also rat liver were studied. For the experiment, a model of adjuvant arthritis was selected and four groups of animals were formed. They were withdrawn from the experiment on the 17, 21 and 26 day. The histological picture indicated that when modeling rheumatoid arthritis, such pathological changes in the immunocompetent organs of rats as edema of the parenchyma and stroma, sclerosis, thickening of the walls of blood vessels, develop during the whole period of observation. A list of descriptors of the studied drug was obtained and it was found that the use of peloid himatomelanic acids in the model of adjuvant arthritis had a pronounced anti-inflammatory effect, as evidenced by the normalization of the morphofunctional state of the spleen, regional lymph nodes and liver.
