The plant growth and yield of Pinellia ternata (Thunb.) Breit. were studied by altitude and tuber weight. The emergence rates in low land area were not different by tuber weights, but it showed earlier emergence date in heavier weight of seed-tuber and low land area. The higher aerial growth such as plant height and number of leaves per plant was the heavier tuber weight in a planting year, but the growth was not different by the weight of tuber at second year after planting. The distribution pattern of tuber size per $m^2$ was not influenced by different seed-tuber weight. The number of harvested tuber was highest at more than 1 g of tuber weight, and followed 1~2 g and less than 2 g. The distribution pattern of fresh tuber yield was not influenced by different altitude and seed-tuber weight. The marketable tuber, 2 g or more, tends to be produced with more than 0.6 g seed-tuber. As the results above-mentioned, it was thought that the high yield was supposed to use seed-tuber over 0.6 g in the fertile soil.

This study was aimed to investigate the difference for carbohydrate accumulation in both the red skinned tuber and white skinned tuber of Jerusalem artichoke (Helianthus tuberosus L.), and to evaluate their tuber yield of seven lines collected from Korea. Jerusalem artichoke tubers were divided into two groups regarding to their skinned colors. Red skinned tuber collected from Euisung region showed the lowest tuber yield as 3,100 kg per 10a, otherwise white skinned tuber collected from Imdong region resulted in the highest tuber production as 6,300 kg per 10a among the six kinds of white skinned tubers. Yield of white skinned tuber was higher than that of red skinned tuber. It was inferred from the result that carbohydrate accumulation in white skinned tuber was highly increased compared to red skinned tuber since after early tuber enlargement.

This study was designed to investigate the modulation of the Corydalis tuber on glycine-activated ion current in rat periaqueductal gray (PAG) neurons. Aqueous extract from Corydalis tuber has been widely used for pain control such as dysmenorrhea, irregular menstruation or amenorrhea with abdominal cramping, neuralgia, headache and gastrointestinal spasm. The PAG region of the brain is known to be involved heavily with nociception. Modulation of the Corydalis tuber on glycine-induced ion current in rat periaqueductal gray (PAG) neurons was studied by a nystatin-perforated patch-clamp technique. High concentrations of Corydalis tuber elicited ion current, which was suppressed by strychnine application. Low concentrations of Corydalis tuber reduced glycine-induced ion currents in the PAG neurons. Inhibitory action of Corydalis tuber on glycine-activated ion current was reduced by treatment with naltrexone, a non- selective opioid antagonist. Application of N-methylmalemide (NEM), a sulfhydryl alkylating agent, also reduced the inhibitory action of Corydalis tuber on glycine-activated ion current in the PAG neurons. These results suggest that the inhibitory effect of Corydalis tuber on glycine-activated ion current in the PAG neurons is one of the analgesic mechanisms of the Corydalis tuber, which may activate descending pain control system in PAG neurons.

Objectives : Corydalis tuber has been used for promoting blood circulation and for relieving pain in Oriental medicine. In the present study, we focused on the antimicrobial activity of Corydalis tuber and compared its antimicrobial activity with the processed Corydalis tuber. Methods : Processing of Corydalis tuber was accomplished by immersing in 5% of acetic acid for 12 h and then by roasting at $250^{\circ}C$ for indicated time periods(0-30 min). Minimum inhibitory concentration(MIC) and the zone of growth inhibition were determined against Propionibacterium acnes(P. acnes). Results : The methanolic extracts of Corydalis tuber showed potent antimicrobial effect(MIC 62.5 ${\mu}g/ml$). Its alkaloidal component, dehydrocorydaline, also exhibited antibacterial activity(MIC 25.0 ${\mu}g/ml$). After processing of Corydalis tuber, its inhibitory effect on the growth of P. acnes was significantly enhanced compared with that of unprocessed Corydalis tuber. Furthermore, elevated content of dehydrocorydaline was found in the processed than the unprocessed Corydalis tuber. However, the different roasting minutes effected on antimicrobial activity. The best roasting time of Corydalis tuber was 10 min, while roasting for the time above 15 min resulted in diminishing antimicrobial activity. Thus, it was concluded that the standardized processing condition of Corydalis tuber should be established to obtain enhanced antimicrobial(P. acnes) activity. Conclusion : For antimicrobial effect against P. acnes, the best processing condition of Corydalis tuber is immersing in 5% of acetic acid for 12 h and by roasting at $250^{\circ}C$ for 10 min.

The following is a list of morphologic and genetic characteristics of Pinellia tuber. 1. The original plant of Pinellia tuber is Pinellia ternata$(T_{HUNB})$$B_{REIT}$. With regards to its external morphology, it is smaller than other Araceae species and its spadix is longer than its leaves, which trifurcate. 2. As regards its internal morphology, its mucous cell is elliptical and the vessel is helical or annular-shaped. Granules exist in abundance and in various shapes. 3. Distribution and size of laticifers are the key criteria on which to differentiate between domestic and imported Pinellia tuber. Laticifers are mainly distributed in the epidermis in domestic Pinellia tuber and in the cortical parenchyma in imported Pinellia tuber. The size of laticifers is somewhere between 1,3 and $8{\mu}m$ in diameter in imported Pinellia tuber bigger than its domestic counterpart. 4. RAPD markers display a great similarity in bands between domestic and Chinese Pinellia tuber. However, RAPD primers 352, 358, 365, 368 and 374 are distinctive markers for domestic Pinellia tuber. In the meantime, North Korean Pinellia tuber, morphologically similar to domestic Pinellia tuber, is genertically distinctive from its domestic counterpart in primers 354, 358, 365, 368, 374 and 379, a finding that supports the postulation that North Korean Pinellia tuber is tuber of another Araceae species.

Truffles are ectomycorrhizal fungi that belong to the genus Tuber. They exhibit symbiotic relationships, particularly with oak (Quercus spp.) and hazel (Corylus spp.) trees. We performed an inoculation using a spore suspension to synthesize mycorrhizae between European truffles, Tuber borchii and Tuber melanosporum, and an indigenous oak species, Quercus acutissima. This resulted in the formation of mycorrhizae within 2 months after inoculation. Despite having the same host plant, differences in features were observed between Tuber species, including color and mantle type. These results indicate that Q. acutissima is a suitable host plant for truffle cultivation in Korea and provide a better understanding of the mycorrhization of T. borchii and T. melanosporum.

Objectives: This study was designed to investigate the analysis of apoptosis by Scirpi Tuber in Hela cell and MCF-7 cell. Methods: For cytotoxic effect of Scirpi Tuber extract, Scirpi Tuber extract were cultured on NIH3T3 cell in vitro. After treatment with various concentration of Scirpi Tuber, cell growth was evaluated in Hela cell and MCF-7 cell. Hoechst 33342 staining was performed to estimate DNA fragment effect of Scirpi Tuber on the apoptosis in Hela cell and MCF-7 cell. Annexin V/PI apoptosis assay was used to estimate the effects of Scirpi Tuber on the early apoptosis in Hela cell MCF-7 cell. All the stained cells were analyzed by a FACS. RT-PCR was used to estimate the apoptosis gene expression effect of Scirpi Tuber extract on Hela cell and MCF-7 cell. Results: Cytotoxic effect of Scirpi Tuber extract was not found on per NIH3T3 cell. The viability of Hela cell was significantly decreased Scirpi Tuber (500, $1000{\mu}g/m\ell$) in Hela cell 1day, 3day and 5days after treatment (p<0.01). The viability of MCF-7 cell was significantly decresed Scirpi Tuber ($1000{\mu}g/m\ell$) in MCF-7 cell (p<0.01), Scirpi Tuber ($500{\mu}g/m\ell$) in MCF-7 cell only 3days after treatment (p<0.01). In RT-PCR analysis, after treatment of $100{\mu}g/m\ell$ of ACR extract, BCL-2 were decreased and BAX, caspase-3 were increased both in Hela cell and MCF-7 cell. DNA fragmentation was observed the Scirpi Tuber on Hela cell and MCF-7 cell. As time goes on DNA fragmentation incresed. In Annexin V/PI apoptosis assay, after treatment of $1mg/m\ell$ of Scirpi Tuber, the early apoptotic cell increased both in Hela cell and MCF-7 cell. As time goes on apoptotic cell increased. Conclusion: Scirpi Tuber appears to have considerable activity on the apoptosis in Hela cell and MCF-7 cell.
