Approximately 10 percent of advanced stomach cancer patients have internal bleeding in their stomach. It is crucial to treat internal bleeding since it severely deteriorates patient's condition, and disturbs process of chemotherapy. There are hemostatic agents and dressing, radiotherapy, endoscopic ligation and coagulation, surgical methods to treat bleeding. However, these methods cannot be executed in some cases in which patient is in terminal stage or not in desirable condition to take these treatments. We are going to introduce a case of advanced gastric cancer patient having stomach bleeding who made a choice to take oriental medical treatments. The patient was on third stage of stomach cancer, had 3200cc of blood transfusion for five times. After diagnosed as not being able to have resection, he started to oriental medical treatments to stop bleeding. From March 28, 2009 to April 16, 2009, we administer 120cc Bojungikgi-tang gamibang to the patient in 90minutes after each meal. During 19days of having Bojungikgi-tang gamibang, we observed that the patient needed significantly lower amount blood transfusion, to 640cc. The patient improves in performance, and was able to eat more. Despite of short period of observation, this case indicates that Bojungikgi-tang gamibang treatment to the patient could work as hemostat, further improved quality of patient's life.

Lung cancer remains the leading cause of cancer-related death throughout the world. Non-small cell lung cancer(NSCLC) is the most deadly form of lung cancer. Patients with non-small cell lung cancer are often found to be unavailable for operation at primary diagnosis. They are typically given conventional chemotherapy. When the tumor progresses during chemotherapy, a change in regimen is considered. The average period of administration differs with the regimen. In this case report, the authors introduce two cases of non-small cell lung cancer patients treated with allergen removed Rhus verniciflua stokes based herbal medicine along with pemetrexed($Alimta^{(R)}$) and erlotinib($Tarceva^{(R)}$). The authors report this case because these molecular-targeted agents were used for longer periods than expected, while improving the performance and other symptoms. Further studies illuminating the synergistic effects through conjunctive treatment with both conventional and Eastern medicine in lung cancer treatment should be performed in the future.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is an extremely rare, potentially fatal, congenital anomaly with a high mortality rate in the first year of life. It occurs rarely in adulthood and may appear with malignant ventricular arrhythmia or sudden death. We report a case of a 49-year-old woman with ALCAPA who presented with dyspnea on exertion. Management was coronary artery bypass grafting to the left anterior descending artery and obtuse marginal arteries, closure of the left main coronary artery ostium, and reestablishment of the dual coronary artery system.

U-City includes various information devices and network techniques, which connect among several information devices. Integrated Management Center, which is the core element of u-City, is designed to manage all services of u-City and carry out the control function for a city. Accordingly, u-City needs the methods of user authentication and security, so these methods must be implemented to integrated management center. This paper is devoted to describe some conventional authentication techniques, and authentication methods and procedures that may be available to u-City network context. Proposed u-City integrated authentication model assigns IP to only right user after authenticating information terminals and users in u-City and authorizes users according to the policy, so this model plays an important role for the security of integrated management center.

Identification of novel therapeutics in glioblastoma remains crucial due to the devastating and infiltrative capacity of this malignancy. The current study was aimed to appraise effect of arsenic trioxide (ATO) in U87MG cells. The results demonstrated that ATO induced apoptosis and impeded proliferation of U87MG cells in a dose-dependent manner and also inhibited classical NF-${\kappa}B$ signaling pathway. ATO further upregulated expression of Bax as an important proapoptotic target of NF-${\kappa}B$ and also inhibited mRNA expression of survivin, c-Myc and hTERT and suppressed telomerase activity. Moreover, ATO significantly increased adhesion of U87MG cells and also diminished transcription of NF-${\kappa}B$ down-stream targets involved in cell migration and invasion, including cathepsin B, uPA, MMP-2, MMP-9 and MMP-14 and suppressed proteolytic activity of cathepsin B, MMP-2 and MMP-9, demonstrating a possible mechanism of ATO effect on a well-known signaling in glioblastoma dissemination. Taken together, here we suggest that ATO inhibits survival and invasion of U87MG cells possibly through NF-${\kappa}B$-mediated inhibition of survivin and telomerase activity and NF-${\kappa}B$-dependent suppression of cathepsin B, MMP-2 and MMP-9.

This study examined correlations between U-Service for U-City and assessment indicators for urban competitiveness. The results of this study show that U-Service is used as a means of strengthening urban competitiveness in six types of cities, despite the differences in degree of contribution. The proper use of U-Service in Safety & Health City and Vitality (Economy) City has significantly contributed to strengthening the competitiveness of such cities. Of the assessment items for urban competitiveness, common items and Culture City type show that U-Service has not contributed much to strengthening urban competitiveness. The analysis shows that because common items are part of the assessment items for urban policies, these items are not suitable to the character of a U-City that implements U-Service through intelligent physical facilities. On the other hand, U-Service related to the Culture City type is relatively less developed. This study found out that U-Service could be used to reinforce urban competitiveness.

In this study, we investigate whether arsenite-induced DNA damage leads to p53-dependent premature senescence using human glioblastoma cells with p53-wild type (U87MG-neo) and p53 deficient (U87MG-E6). A dose dependent relationship between arsenite and reduced cell growth is demonstrated, as well as induced ${\gamma}H2AX$ foci formation in both U87MG-neo and U87MG-E6 cells at low concentrations of arsenite. Senescence was induced by arsenite with senescence-associated ${\beta}$-galactosidase staining. Dimethyl- and trimethyl-lysine 9 of histone H3 (H3DMK9 and H3TMK9) foci formation was accompanied by p21 accumulation only in U87MG-neo but not in U87MG-E6 cells. This suggests that arsenite induces premature senescence as a result of DNA damage with heterochromatin forming through a p53/p21 dependent pathway. p21 and p53 siRNA consistently decreased H3TMK9 foci formation in U87M G-neo but not in U87MG-E6 cells after arsenite treatment. Taken together, arsenite reduces cell growth independently of p53 and induces premature senescence via p53/p21-dependent pathway following DNA damage.

Purpose: The aim of this study was to assess the diagnostic efficacy of noninvasive prenatal screening for trisomy 18 by assessing the levels of unmethylated-maspin (U-maspin) and fetal nuchal translucency (NT) thickness during the first trimester of pregnancy. Materials and Methods: A nested case-control study was conducted using maternal plasma samples collected from 65 pregnant women carrying 11 fetuses with trisomy 18 and 54 normal fetuses. We compared the U-maspin levels, NT thicknesses, or a combination of both in the first trimester between the case and control groups. Results: U-maspin levels and NT thickness were significantly elevated in the first trimester in pregnant women carrying fetuses with trisomy 18 when compared to those carrying normal fetuses (27.2 vs. 6.6 copies/mL, P<0.001 for U-maspin; 5.9 vs. 2.0 mm, P<0.001 for NT). The sensitivities of the U-maspin levels and NT thickness in prenatal screening for fetal trisomy 18 were 90.9% and 90.9%, respectively, with a specificity of 98.1%. The combined U-maspin levels and NT thickness had a sensitivity of 100% in prenatal screening for fetal trisomy 18, with a specificity of 98.1%. Conclusion: A combination of U-maspin levels and NT thickness is highly efficacious for noninvasive prenatal screening of fetal trisomy 18 in the first trimester of pregnancy.

For the development and management of u-City(ubiquitous city), Ubiquitous City Construction Law was enacted(March 3, 2008) to form the legal basis of u-City plan, construction and managements afterwards. Among u-City elements, the u-City Management Center has its own meaning and importance in roles which are crucial to the u-City developments, and its legal establishment is one of the core u-City realization factors. In spite of its crucial position for u-City, the legal arrangement of its basis concept, physical/systematic structures, and managerial finance sources and their standardizations are very immature. Therefore, the purpose of this study is to analyse its overall problem issues and then to suggest the basic directions and enforcement strategies to form its legal basis.
