Changes in hematological parameters when using silver preparations in laboratory ICR mice infected with the Newcastle disease virus

Abstract

The results of blood tests are important indicators for assessing and monitoring the health status, adaptation processes and metabolic states of the body. Currently, there is insufficient data on the effect of the Newcastle disease virus on peripheral blood parameters in animals, and there is also no information on changes in these parameters during Newcastle disease and the simultaneous use of silver preparations in animals. Although the mechanisms of the antiviral action of silver nanoparticles are not yet fully studied, researches show their effectiveness. The purpose of research was to study changes in hematological parameters with using silver preparations in laboratory ICR mice infected with Newcastle disease virus. The object of the study was the blood of laboratory ICR mice, infected with the Newcastle disease virus, and healthy ones as a control, and also silver preparations: Argosil and ArgovitMaxi. As a result of hematological studies, a significant effect of the Newcastle disease virus on hematological parameters was established. Deviations of the main blood parameters in infected animals were demonstrated: there was an increase in the content of granulocytes, the number of erythrocytes, the hemoglobin content and hematocrit; the number of lymphocytes and the average erythrocytes volume were reduced. It was also found that the use of the preparation Argosil significantly reduces the content of monocytes in ICR mice against the background of Newcastle disease viral infection. The use of the preparation Argovit significantly affects the decrease in monocytes and erythrocyte blood parameters: it increases the number of erythrocytes, hemoglobin, hematocrit, and reduces the average hemoglobin content in an erythrocyte, the average hemoglobin concentration in an erythrocyte.
