The immunomodulatory effect of asperula odorata l

The research presents results of in vitro studies of the effect of dry extracts of Asperula odorata and Asperula humifusa on the functional activity of macrophages and their hematogenous precursors. It has been found that the extracts studied reveal a dose-dependent stimulatory effect on the transformation and phagocytic activities of macrophages and their mononuclear precursors. The Asperula humifusa dry extract exhibits a more expressed immunomodulatory effect in the dose range from 5 to 100 μg/ml. When using the extracts studied in the dose of 100 μg/ml the maximal stimulation of the functional activity of immune competent cells has been observed. Therefore, the extract of Asperula odorata increases the transformation activity of mononuclear cells by 57%, the phagocytic index is 46% and the phagocytic number is 54% compared to the control. The extract of Asperula humifusa increases the transformation activity by 64%, the phagocytic index is 44% and the phagocytic number is 56%. The research results confirm opportunities of using the given dry extracts with the purpose of immunopathological states correction.
