Objective : The purpose of this study was to investigate the effect of fermented Artemisiae Argyi Folium(AAF) on some activities of human hepatoma cell, HepG2. Method : To investigate the effect of fermented Artemisiae Argyi Folium(AAF) activity on the human hepatoma cells, AAF extracts was fermented by Lactobacillus pentosus K34(AFL) and Sacchromyces cerevisiae STV89(AFS). And the effects of AFL or AFS on the activities of HepG2 cell, such as cell viability, nitric oxide(NO) production and reactive oxygen species(ROS) production, were tested. Result : Human Hepatoma Cells were incubated each for 3 hours and 24 hours. Human Hepatoma Cells treated with the extract was measured with MTT assay. Then AFL was found to be non-toxic at concentrations of 10 ug/mL(3h), 100 ug/mL(24h) or more. AFS was the same result at concentrations of more than 10 ug/mL. The extract increased ROS generation in Human Hepatoma Cells. AFL increased at concentrations of 100 ug/mL more (3h, also 10 ug/mL more) and 50 ug/mL(24h) and AFS increased both 50 ug/mL. In point of NO generation, AFL inhibited at concentrations of 10 ug/mL(3h) and 100 ug/mL(24h) more (3h, also 10 ug/mL more) and AFS also inhibited 50 ug/mL or more. Conclusion : AFL and AFS, obtained from Artemisiae Argyi Folium extracts by fermentation, reduced the NO production and increased ROS production in HepG2 cell, without cytotoxicity on HepG2 cell. The results suggested that AFL and AFS increased the immunological effects of Artemisiae Argyi Folium extracts.

Objectives : This research aimed to study the cytotoxicity and immuno modulating activity of fermented Artemisia argyi Lev. et Vant.(Compositae). Methods : Effect of fermented Artemisiae Argyi Folium extracts, which were fermented by Sacchromyces cerevisiae STV89(AFS), on cell viability, generation of ROS within cells, generation of NO and the level of cytokines($TNF-{\alpha}$ and IL-6) was measured using mouse macrophage RAW 264.7 cell. Results : 1. Result of MTT assay conducted to verify the cytotoxicity of fermented Artemisiae argyi folium extract illustrated that, when fermented Artemisiae argyi folium extract was processed for each concentration, there was no excessive induction of cytoxicity in the RAW 264.7 cell. 2. Fermented Artemisiae Argyi Folium extract increased the generation of H2O2 within RAW 264.7 cell as well as significantly increased inhibition of generation of H2O2 in macrophage induced by LPS. 3. Fermented Artemisiae Argyi Folium extract inhibited generation of NO in RAW 264.7 cell, and significantly inhibited increase in generation of NO of macrophage induced by LPS. 4. Fermented Artemisiae Argyi Folium extract, AFS has significantly reduced the increase in the generation of $TNF-{\alpha}$ above 10 ${\mu}g/mL$. 5. Fermented Artemisiae Argyi Folium extract, AFS has significantly reduced the increase in generation of IL-6 above 50 ${\mu}g/mL$. Conclusions : AFS fermented extract produced from Artemisiae Argyi Flium, have increased generation of ROS and reduced generation of NO in RAW 264.7 cell without excessively inducing cytotoxicity of RAW 264.7 cell. In addition, they displayed significant immuno modulating activities including inhibition of generation of $TNF-{\alpha}$ and IL-6 in macrophage, induced by LPS.
