Estimation of the reserve capacity of Myodes glareolus after acute irradiation using hematological indicators

Abstract

The problem of identifying the sensitivity of living organisms to ionizing irradiation remains relevant, considering the spread of anthropogenic environmental pollution. The study on the effect of single X-ray irradiation (1,5 Gy) on peripheral blood of bank voles (Myodes glareolus (Schreber, 1780)) captured within territories with background radiation level was conducted. Hematological indicators, characterizing the overall condition of performance of the body, were determined dynamically on the first and seventh days after exposure to detect both early changes and the rate of recovery processes. The patterns and features of the main components of leukocyte formula found in peripheral blood of irradiated animals are being discussed. Differences between irradiated and control mouse-like rodents are shown, using parameters of erythrocytes and leukocytes. The analysis of changes in the peripheral blood of irradiated bank voles indicates the high reserve capacity of the body, according to its ability to restore homeostasis.
