| description | The results of studying the effect of isoliquiritigenin on animal survival in the model of staphylococcal infection and the function of human and animal phagocytes are presented in this article.The aim of the investigation was to study the effect of an isoliquiritigenin preliminary administration on the survival of animals against the background of staphylococcal infection, as well as on the function of phagocytes in mice and humans.Materials and methods. To assess the survival of Balb/C mice, a model of infection caused by Staphylococcus aureus J49 ATCC 25923 with the construction of Kaplan-Meier curves, was used. The effect on the phagocytes functions was studied by assessing the peptone-induced migration of phagocytes into the abdominal cavity of Balb/C mice, the absorption activity of phagocytes (neutrophils and monocytes) of human blood, as well as their production of reactive oxygen intermediates (ROIs) using а flow cytometry.Results. It was found out that a preliminary triple intraperitoneal administration of isoliquiritigenin (30 mg/kg) increases the survival rate of Balb/C mice in staphylococcal infection caused by Staphylococcus aureus J49 ATCC 25923. At the same time, isoliquiritigenin dose-dependently activates the production of reactive oxygen intermediates by human neutrophils and monocytes without statistically significantly suppressing a phagocytic activity of monocytes and neutrophils against fluoresceinisothiocyanate-labeled S. aureus J 49 ATCC 25923, as well as peptone-induced migration of phagocytes into the abdominal cavity of mice.Conclusion. Thus, a preliminary administration of isoliquiritigenin increases the survival rate of mice with staphylococcal infection and increases the production of reactive oxygen intermediates by phagocytes. The data obtained, can become the basis for further research of antibacterial and immunotropic effects of isoliquiritigenin in order to find new drugs for the treatment of staphylococcal infection. |
