Assessment of the state of non-specific resistance of the body of military personnel according to the leukogram in various professional activities in the Arctic

Abstract

A comparative analysis of the state of non-specific resistance of the body in military personnel serving under a contract, divided into groups according to the principle of work probation (with different duration of professional activity in the Arctic): up to 5 (n = 21) and up to 10 years (n = 30) years, by leukocyte index. According to the leukogram, leukocyte indices (ratios) were calculated: neutrophils/lymphocytes (NIL), lymphocytes/neutrophils (LI), lymphocytes/monocytes (ILM), neutrophils/monocytes (NIL), lymphocytes/eosinophils (ISLE), monocytes/lymphocytes (ML), lymphocytes/to the percentage of segmented neutrophils (IG), the sum of eosinophils and lymphocytes/monocytes — immunoreactivity of the organism (IIR). We established the presence of statistically significant differences in 5 indices out of 9 determined. ISLM in group No. 2 was higher by 7.0 %, ISMI — by 7.8 %, ISLE — by 29.6 %, IIR — by 4.2 %. According to the indicators of IG, MLI, IIR, the level of immune defense of the body of military personnel was within the normal range. The conditions of activity in the Arctic had a negative impact on the humoral and cellular immunity (LI), phagocytic activity of cells (CMI). Leukocyte indices (ISLM, ISNL, ISLE, IIR) testified that in persons with a longer period of professional activity, the level of adaptation of the organism to extreme living conditions is higher. Leukocyte indices revealed the features of the state of the protective functions of the body of military personnel during work in the Arctic, they are informative. Carrying out blood tests, in terms of assessing leukograms in extreme conditions, allows you to use these studies in the form of express methods.
