Purpose : This study was undertaken to evaluate the inhibitory effects of Arisaematis rhizoma on the cell proliferation in HeLa cells. Methods : The cultured cell after treatment in the different duration in 24, 48, 72 hours with solution of 1%. 5%, 10% Arisaematis rhizoma was quantified by trypan blue exclusin method. The control group was treated with 2% FBS in the different duration in 24, 48, 72 hours. We examined DNA of activated caspase by FACS analysis, caspase-3 activity, DNA fragmentation by DNA laddering, activity of HeLa Cells by the XTT assay, activity of MAP kinase by RT-PCR analysis. Results : After 72 hours culture, the growth activities of 1%, 5%, 10% Arisaematis rhizoma-treated Hela cell were significantly reduced with control group, respectively. After 24 hours culture, the ratio of cells showing caspase activity by FACS analysis were increased in 1%, 5%, 10% Arisaematis rhizoma-treated Hela cell. It were also increased in 48 hours culture of 10% and 72 hours culture of 5%, 10% Arisaematis rhizoma-treated Hela cell. In 24, 48 and 72 hours culture, DNA fragmentations of 5%, 10% Arisaematis rhizoma-treated Hela cell were obviously observed. These results meaned that Arisaematis rhizoma induces apoptosis of HeLa cells. It was supported by increased caspase-3 activity and decreased MAP kinase activity according to time periods and concentrations of Arisaematis rhizoma solution. Conclusion : The study shows that Arisaematis rhizoma has inhibitory effect on cell proliferation and induction capacity of apoptosis of human cevical carcinoma cell line, HeLa cells, in vitro. These results suggest that Arisaematis rhizoma should be useful for treatment of human cevical carcinoma.

This research premises that design failure in the market can stem partially from the gap between designer's communication intension through design and consumer's signification for design. Therefore, it's necessary that designers should examine and understand consumer's signification process for design factors or overall design images that they consider in the design process. For this, this research suggests that understanding consumer's signification process is possible by performing value categorization, consumer segmentation, value identification of main target consumers and relationship examination between value of target consumers and design attributes based on Means-End model by reviewing various theoretical backgrounds. In addition, this research suggests contents and methods for performing each step of understanding consumer's signification process. Also, Laddering was suggested as a method for the study and a case study was performed by it. Finally this research claims that understanding consumer's signification process can be one of the methods that decrease failure possibility rather increase success possibility of design in the market.
