НЕСПЕЦИФИЧЕСКАЯ РЕЗИСТЕНТНОСТЬ ОРГАНИЗМА ЛАБОРАТОРНЫХ КРЫС ПРИ ВОЗДЕЙСТВИИ ЭКСПЕРИМЕНТАЛЬНОЙ ГИПОКСИЕЙ

Abstract

To date, the search for the most informa-tive and simple methods for diagnose of adaptive capabilities is an urgent problem of veterinary medicine and adaptive physiolo-gy. The direction of the animal body's re-sponse to the hypoxic factor has not been sufficiently studied. Objective: the analyze of the dynamics of changes of the main indi-cators in the leukogram under the influence of hypoxia, as well as the study of the role of leukocyte, indices the analysis of the level of resistance in rats. The animals were divided into two groups: in the first case, the animals were injected with cytoflavin at a dose of 135 mg/kg before the hypoxia ses-sion, and in the second case, saline was ad-ministered at an equivalent dose. The blood test was performed on a hematological auto-matic analyzer, and the clinical parameters of peripheral blood were determined. Mathe-matically, the leukogram was used to deter-mine: the white blood cell shift index (ISLC), the lymphocyte-monocyte ratio in-dex (ISLM), and the lymphocyte-granulocyte index (ILG). The results of the study showed that the course of hypoxia contributes to a number of changes in the blood composition, for 21 days. There was an increase in the number of white blood cells in both groups, a change in the parame-ters of the leukocyte formula-a decrease in the content of lymphocytes, with a simulta-neous increase in the proportion of mono-cytes. The use of interval hypoxia caused a decrease in the content of red blood cells in animals of the first group, a decrease in the concentration of hemoglobin and hematocrit in both groups studied. The number of plate-lets increased, which also indicates the start of adaptive reactions in the body of rats. The use of leukocyte indices is the assess to the level of resistance of the body and showed their high significance and informa-tive value in modeling experimental hypoxia.
