  • Multiple shoot formation was obtained from excised axillary buds of Achyranthes japonica NAKAI cultured on MS media containing various growth regulators such as auxin and cytokinin. The highest average number of shoots was obtained in 1 mg/L NAA and 2 mg/L BA after 6 weeks (25.8 adventitious shoots per node). Although the regeneration rate was less than the former condition, optimal combination for the production of more shoots with a suitable size was 0.5 mg/L NAA and 1 mg/L BA (19.7 adventitious shoots per node). Roots were induced from regenerated shoots after 3 weeks culture, transferred to 1/2 MS medium supplemented with 0.1 mg/L IBA. Micropropagated plants were successfully transferred to soil.

  • Sensor nodes depend on batteries for energy source in Wireless Sensor Networks (WSNs). Low Energy Adaptive Clustering Hierarchy (LEACH) is a representative cluster-based routing protocol designed to ensure energy use efficiency whereas the virtual cluster exchange routing (VCR) information only with its closest node to build a network. In this paper, a protocol scheme was proposed wherein member nodes are designed to compare the currently sensed data with the previously sensed one and to switch to sleep mode when a match is achieved. The design is to help improve the transmission energy efficiency too.

  • Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a technique developed to allow mediastinal staging of lung cancer and also to evaluate intrathoracic lymphadenopathy. In a tuberculosis-endemic area, tuberculosis should be considered as an etiology of mediastinal lymphadenopathy. The aim of this study was to investigate the utility of the routine culture for tuberculosis from specimens of EBUS-TBNA. Methods: We prospectively performed routine culture for tuberculosis from aspiration or core biopsy specimens got from 86 patients who had undergone EBUS-TBNA due to mediastinal lymphadenopathy between March 2010 and March 2011. Results: A total of 135 lymph node aspiration and 118 core biopsy specimens were included in this analysis. We confirmed the malignancy in 62 (72.9%), tuberculosis in 7 (8.1%), sarcoidosis in 7 (8.1%), asperogillosis in 2 (2.3%) and pneumoconiosis in 2 (2.3%) patients. One lung cancer patient had pulmonary tuberculosis coincidentally and 5 patients had unknown lymphadenopathy. The number of positive culture for Mycobacterium tuberculsosis by EBUS-TBNA is 2 (1.5%) from 135 lymph node aspiration specimens and 2 (1.7%) from 118 core biopsy specimens. Out of eight patients confirmed with tuberculosis, only one patient had positive mycobacterial culture of aspiration specimen from EBUS-TBNA without histopathologic diagnosis. Conclusion: These results propose that routine culture for tuberculosis from EBUS-TBNA may not provide additional information for the diagnosis of coincident tuberculous lymphadenitis. However, if there is any possibility of tuberculous lymphadenopathy or pulmonary tuberculosis, it should be considered to perform EBUS-TBNA in patients who have negative sputum AFB smears or no sputum production.

  • Alstroemeria (Alstroemeriaceae) is one of the most important cut flowers in international market. Especially, characteristics like long vase-life, various colors, tolerance to low temperature and a low energy requirement during cultivation have stimulated this success. Because of its characteristics such as low multiplication rates, time-consuming process and high risk of carrying viral disease, in vitro propagation techniques based on rhizome meristems culture have been developing nowadays. The callus induction has various cultivation sites compared with the direct plant generation method, and if the callus is maintained well, the plant differentiation can be performed simultaneously while maintaining the callus, so that it can be used for mass proliferation. In this study, we tested various hormones and cultivars for efficient callus induction. As a result of culturing between the nodes and the internodes, the callus began to be formed after 8 weeks, and the calli incidence in the nodes was higher than that between the internodes. Also, in the comparison of 2,4-D and picloram, the callus incidence rate was up to 2 times higher in the medium treated with 2,4-D. Using these results, it is thought that it will help establish the system of mass propagation system of Alstroemeria and cultivate new varieties.

  • Potato (Solamum tuberosum 'Dejima') plantlets were investigated on culture type and initial quantity of inoculation in bioreactor and survival rate by hydroponics for mass production. rode stems (1 to 1.5cm in length) of potato plantlets multiplied in vitro were grown for 3 weeks in liquid Murashige and Skoog (MS) medium with sucrose $30 g\; L^{-1}$. When plantlets (80-node inoculation) were raised in 10L balloon type bubble (BB) bioreactor, the healthiest growth of plantlets was obtained from explants cultured in ebb & flow culture with medium supplied periodically 12 times per day. The suitable inoculation quantity of 20L BB bioreactor was 120 pieces of stem segments (mean 2.2g fresh weight) in ebb & flow culture. Number of nodal shoot was eight on the average. In controlled culture room, survival rate of plantlets at 7 days after stem cutting was above $70\%$ when they were acclimatized by hydroponics grown in deep flow and solid medium culture. The highest survival rate of the stem cutting plantlets was in nutrient solution adjusted to EC $1.4dS{\cdot}m^{-1}$. Stem cutting plantlets through one culture could be obtained $670\~900$, when plantlets were grown in ebb & flow culture during 3 weeks using a 20L bioreactor with initial 120 pieces of nodal segments. 11 is possible In do mass production of seedlings cultured in bioreactor and hydroponics.

  • Plantlet regeneration in Asteracantha longifolia(L.) Nees (Acanthaceae), a medicinal herb has been achieved from seedling explants on basal MS medium. Three different seedling explants including node, internode and leaf segments on used. Of these three explant, leaf explants gave better response for both callus mediated organogenesis and direct multiple shoot induction. Number of explants showing differentiation of shout buds was higher on MS media supplemented with BA compared to kinetin. MS medium fortified with BA ($2.0mgl^{-1}$) and NAA ($0.5mgl^{-1}$) was found to be most suitable for both callus mediated organogenesis and elongation of shouts. The elongated shoots were successfully routed on MS medium fortified with NAA or IBA. Among them $0.1mgl^{-1}$ NAA or $0.2mgl^{-1}$ IBA provides better response for rhizogenesis. Regenerated plantlets were successfully established in soil where 85.4% or them developed into morphologically normal and fertile plants. RAPD profiling using four decamer primers confirmed the genetic uniformity of the regenerated plantlets and substantiated the efficacy and suitability of this protocol for in vitro propagation of A. longifolia.

  • The accuracy of fine needle aspiration cytology(FNAC) of the lymph node was investigated through a review of 176 FNAC cases and the corresponding biopsies. We chose 157 FNAC cases after the exclusion of 19 inadequate ones. Sensitivity of malignancy was 94.0%, specificity 100%, false negativity 6.0%, and false positivity 0.0%. The overall diagnostic accuracy was 96.8%. Sensitivity of metastatic carcinoma was 98.0% and that of malignant lymphoma was 87.9%. False negative cases included one metastatic carcinoma and four malignant lymphomas. The aspirates of metastatic carcinoma with false negativity exhibited a diffuse smear of keratin debris without viable cells, which led to the difficulty in differentiation from benign epithelial cyst. The cases of malignant lymphoma with false negative diagnosis were two Hodgkin diseases, one Lennert's lymphoma, and one peripheral T cell lymphoma in the histologic sections. On the analysis of 39 cases of tuberculosis, 17 cases(43.6%) were diagnosed as tuberculosis, 4(10.3%) as granulomatous lymphadenitis, 3(7.7%) as necrotizing lymphadenitis, and 15(38.5%) as reactive hyperplasia or pyogenic inflammation. Sensitivity of tuberculosis was 53.9%. In conclusion, lymph node FNAC is an excellent non-invasive diagnostic tool for the diagnosis of metastatic carcinoma. The diagnostic accuracy of malignant lymphoma could be improved with flow cytometry or polymerase chain reaction for antigen receptor genes. For the FNAC diagnosis of tuberculosis, AFB stain, culture, and PCR would be helpful as adjuvant techniques.

  • This experiment was carried out to investigate the growth characteristics of virus-free sweetpotato in hydroponic bag culture. The rooted one-node and upper-shoot cuttings of 'Yeonhwangmi' and 'Mannamiwere' transplanted into the plastic bag (0.5 mm of thickness, $W300{\times}L1,200{\times}H120mm$) culture system filled with commercial horticultural media (TKS-2, Flora Gard Co.) and cocopeat + perlite (3 : 7, 5 : 5, 7 : 3, (v/v). Nutrient solution of National Horticultural Research Station in Japan was separately irrigated $3times{\times}30minutes$ per day (10:00, 14:00 and 20:00 with timer control) by the drip irrigation. The growth of two varieties was not significantly different among four substrates in 15 days, but it was excellent in commercial horticultural media (TKS-2) and cocopeat 3 : perlite 7 (v/v) in 20 days. The growth in 'Yeonhwangmiwas' promoted than that in 'Mannami', and the upper-shoot cuttings of 'Yeonhwangmi' and 'Mannami' showed a significant vine elongation (over 10 and 2 cm, respectively) compared to the one-node cuttings. Fresh weight and dry weight in cocopeat 3 : perlite 7 (v/v) were significant increased than that in cocopeat 7 : perlite 3 (v/v). Therefore, the bag culture system filed with cocopeat 3 : perlite 7 (v/v) was successfully applied on propagation of virus-free sweetpotato seedling, and the result expected that the bag culture system could be commercialized without high financial costs for farmers.
