In this article, it is shown that the healing properties of the plant Anthemis tinctoria L. are associated with the presence of polyacetylene in its roots, flavonoids, glucosides, and essential oil compounds in its flowers. In addition, this plant contains quercetin, rubber, Vitamin P, xanthophyll, dyes, and alkaloids beneficial for the human body. In this case, a number of experiments were conducted using the following isolators to isolate the active biologically active substance from the plant yellow chamomile (Anthemis tinctoria L.). As a separator, purified water, ethyl alcohol with different percentage concentrations, i.e., 40, 70, 90, 96% ethyl alcohol, were used. Using the HPLC method, the content of flavonoids in the liquid extract obtained from the raw material of the plant Anthemis tinctoria L. was determined, which was carried out in the "Agilent 1260 Infinity" mode, spectrophotometric detector, chromatographic column Agilent S18 5 μm, 4.6x250 mm, gradient mode.

The article emphasizes that accurate physiological interpretation of blood parameters requires a shift from a "slice of values" to modeling time dynamics and contextual normalization for individual conditions. It is concluded that the most promising approach is the integration of cellular, biochemical, and rheological data into unified functional indices, enabling the comparison of adaptation profiles and the identification of early dysregulation before clinical manifestations.

Disturbances in water balance in the body significantly affect numerous physiological processes. Under conditions of dehydration, hemoconcentration, microcirculatory disorders, and tissue hypoxia may negatively influence various components of the immune system, particularly gut-associated lymphoid tissues. The intestinal lymphatic system, including Peyer’s patches and solitary lymphoid follicles, plays an important role in the formation of local immune responses. The aim of this study was to determine the morphological and morphometric changes in the lymphoid follicles of the small intestine under conditions of experimental dehydration. The study was carried out under laboratory conditions using white rats as an experimental model. In the experimental group of animals, dehydration was induced by restricting fluid intake. The obtained intestinal tissues were examined using histological methods followed by detailed morphological analysis. The results of the study demonstrated that dehydration leads to a decrease in the number of lymphocytes within intestinal lymphoid follicles, alterations in cellular composition, and morphological restructuring of the lymphatic capillary network. In addition, dystrophic and destructive processes in the intestinal wall layers were observed to intensify. The obtained results contribute to a better understanding of structural changes in the intestinal immune system under dehydration conditions and help clarify the pathomorphological mechanisms associated with water deficiency in the organism

Pulpitis is an inflammatory condition of the dental pulp and is one of the most common diseases in therapeutic dentistry. This paper analyzes the etiology, clinical features, and modern treatment methods of pulpitis. Special attention is given to biological (conservative) treatment, vital amputation, and devital extirpation methods. The use of modern anesthesia techniques and advanced dental materials significantly increases treatment effectiveness. The correct selection of treatment methods plays a crucial role in preserving tooth function
