Objectives : The purpose of this study was to investigate the anticancer effects of Bodusan (BDS) on SNU-1 cells, a human gastric cancer cell line. Methods : To study the cytotoxic effect of BDS on SNU-1 cells, the cells were treated with various concentrations of BDS and then cell viability was determined by XTT reduction method and trypan blue exclusion assay. The typical signs of apoptosis, was examined by western blot analysis. BDS-induced MAPK activation was also examined by Western blot for phosphorylated ERK and p38. Results : BDS reduced proliferation of SNU-1 cells in a dose-dependent manner and decreased procaspase 3 level in a dose-dependent manner and induced the clevage of PARP at concentration > 500 ${\mu}g/ml$. BDS also triggered the mitochondrial apoptotic signaling by increasing the release of cytochrome C from mitochondria to cytosol and reducing the level of anti-apoptotic Bcl-2. BDS significantly decreased ERK phosphorylation and increased p38 phosphorylation in a dose-dependent manner. Futhermore, BDS treatment up-regulated p53 and p21waf expression in a dose-dependent manner. Conclusion : BDS-induced apoptosis is MAP kinase-dependent apoptoric pathway and arrested SNU-1 cells at the G0/G1 of cell cycle. These results suggest that BDS is potentially useful as a chemotherapeutic agent in human gastric cancer.

Objectives : Inflammation is important event in the development of vascular diseases including hypertension, atherosclerosis, and restenosis. Bodusan (BDS) was a traditional Korean herbal medicine and widely used in treatment of gastrointestinal complaint and stomach ulcer. The aim of this study was to determine whether BDS and its components inhibit production of nitrite, PGE2 and proinflammatory cytokines in lipopolysaccharide (LPS)-treated RAW 264.7 macrophages. Methods : Cytotoxic activity of BDS and its components on RAW 264.7 cells was using 5-(3caroboxymcrophages. eth-oxyphenyj)-2H-tetra-zolium inner salt (MTS) assay. The nitric oxide (NO) production was measured by Griess reagent system. And proinflammatory cytokines were measured by ELISA kit. The levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression were detected by western blot. Results : Our results indicated that BDS and its components significantly inhibited the LPS-induced NO and PGE2 production. Moreover. BDS and its components inhibited iNOS and COX-2 expression accompanied by an attenuation of TNF-${\alpha}$, IL-11${\beta}$, IL-6 and MCP-1 formation in macrophages. Conclusions: These results indicate that BDS and its components have potential as an anti-inflammatory agent.

Objectives : This study was evaluated to elucidate the inhibitory potential of Bodusan (BDS) and its components, Strychnos ignatii semen (SIS) and Glycyrrhizae Radix (GR), on human aortic smooth muscle cells (HASMC) migration and production of matrix metalloproteinase (MMP)-2 and MMP-9 by $TNF-{\alpha}$ treatment. Methods : Cytotoxic activity of BDS and its components on HASMC was using 5-(3-caroboxymeth- oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. Effect of BDS, SIS and GR on $TNF-{\alpha}-induced$ HASMC migration underside of matrigel filter was stained with hematoxylin-eosin. And total number of cells that migrated to the underside of the filter was counted. MMP-2 and MMP-9 activity was evaluated by gelatin zymography assay. Results : The matrigel migration assay showed that BDS effectively inhibited the $TNF-{\alpha}-induced$ migration of HASMC. Moreover, BDS significantly inhibited MMP-9 activity. Our present study demonstrates that BDS and its components inhibits $TNF-{\alpha}-induced$ HASMC migration and MMP-9 activity. The inhibitory effect of BDS extract is more potent than that of its component herb extracts. Conclusions : These results provide evidence that BDS has multiple effects in the inhibition of HASMC migration and may offer a therapeutic approach to block HASMC migration.
