Abstract

The Korean traditional medicinal (KTM) herbs such as Angelicae gigantis, Rehmannia glutinosa, Paeoniae lactiflora, Cnidii officinale, Salviae miltiorrhizae, and Millettia reticulata, and prescribed formula Samultang, and Bohyultang improve the function of the hematopoietic system and nourishing the body to promote health. However, there are limited scientific background on the mode of action of these medicine. To understand the diverse actions following traditional medicine stimulation, we determined the production of hematopoietic cytokine, thrombopoietin, stem cell factor, and interleukin-3 (IL-3) in KlM treated bone marrow cells. When bone marrow cells were treated with KTM, the expression of hematopoietic cytokine were increased in RT-PCR and ELISA analysis. Furthermore, when the bone marrow cells were separated into adherent celis and suspension cells and were treated with KTM, we found the increase of TPO gene expressions in suspension cells. Meanwhile, other hematopoietic cytokine gene expression in bone marrow cells was higher as whole than when adherent cells and suspension cells was separated. Therefore, we could know the interaction of two cells that increases the cytokine expression. These results suggest that KTM has hematopoietic effects through increasing the production of cytokine.
