Abstract:
The influence of Sorbus sibirica, Calendula officinalis and Althaea officinalis extracts on the humoral immune response and nonspecific resistance of mice to immunosuppression by cyclophosphan was studied. It was shown that these extracts are not inferior to Echinacea purpurea tincture in terms of stimulation of humoral immune response, phagocytic and bactericidal activity of peritoneal macrophages but exceed effect of E. purpurea on phagocytic activity of peripheral blood neutrophils.
