摘要：
The aim of the study was to identify the features of the cellular composition and cytokine profile of bronchoalveolar lavage fluid in rats in a model of diet-induced metabolic syndrome. Materials and methods. In an experiment on animals (rats), a model of metabolic syndrome (MS) induced by a high-fat and high-carbohydrate diet was reproduced. To assess the viability of the reproduced model, biochemical and morphometric methods were used, such as measurement of body weight, specific gravity of liver and visceral fat, and blood pressure, determination of glucose concentration in the blood (including a glucose tolerance test), as well as determination of blood lipid parameters. To assess the intensity of the inflammatory response in the blood, the concentration of total protein, the total number of leukocytes, and the levels of immunocytokines (interleukin (IL)-6, IL-10, tumor necrosis factor (TNF)& alpha;, monocyte chemoattractant protein (MCP)-1) were determined. Open bronchoalveolar lavage was performed on the isolated heart - lung complex. The concentration of protein, immunocytokines (IL-6, IL-10, TNF & alpha;, MCP-1), the total number of leukocytes, and the ratio of their morphological types were determined in the bronchoalveolar lavage fluid (BALF). Results. In animals with MS, an increase in the total number of leukocytes in the blood due to granulocytes and a rise in the concentration of protein, TNF & alpha;, and IL-10 were revealed compared with the parameters in the controls. BALF analysis revealed an increase in the concentration of protein, the total number of leukocytes, and the absolute number of alveolar macrophages, neutrophil granulocytes, and lymphocytes. The levels of IL-6 and MCP-1 were more than 1.5 times higher. Conclusion. Changes in the qualitative and quantitative parameters of BALF are inflammatory in nature and are formed during a systemic inflammatory response accompanying metabolic disorders in modeling MS in rats in the experiment.
