  • Purpose: Porphyromonas gingivalis and Tannerella forsythia have been implicated as the major etiologic agents of periodontal disease. These two bacteria are frequently isolated together from the periodontal lesion, and it has been suggested that their interaction may increase each one's virulence potential. The purpose of this study was to identify proteins on the surface of these organisms that are involved in interbacterial binding. Methods: Biotin labeling of surface proteins of P. gingivalis and T. forsythia and liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis was performed to identify surface proteins involved in the coaggregating activity between P. gingivalis and T. forsythia. Results: It was found that three major T. forsythia proteins sized 161, 100, and 62 kDa were involved in binding to P. gingivalis, and P. gingivalis proteins sized 35, 32, and 26 kDa were involved in binding to T. forsythia cells. Conclusions: LC-MS/MS analysis identified one T. forsythia surface protein (TonB-linked outer membrane protein) involved in interbacterial binding to P. gingivalis. However, the nature of other T. forsythia and P. gingivalis surface proteins identified by biotin labeling could not be determined. Further analysis of these proteins will help elucidate the molecular mechanisms that mediate coaggregation between P. gingivalis and T. forsythia.

  • Umbelliferae medicinal crops have low germination under natural condition. Special objective of this study is to investigate morphological characteristics of seeds and effects of environmental factors such as light and temperature on their germination and seedling growth in Umbelliferae plants, using them as oriental medicine materials. Fruits of Umbelliferae are bi-partite type and form 2 seeds. Their oil canals and funiculus or carpaphore has apparently specific shape. Seed shape of Buplerum falcatum, Ligusticum acutilobum and Foeniculum vulgare are oblong, Ledeboutiella seseloides, Angelica dahurica, Angelica gigas elliptic, and Ostericum koreanum ovate. Color of seed coats varied from yellow to dark brown. Seed size was 3.2 to 6.9 mm in length, 1.7 to 4.9 mm in width. One thousand-seed weight of Buplerum falcatum was lowest(at 1,660 mg) and Ledebouriella seseloides and Angelica gigas were relatively highest(at 3,970 mg) having larger size than any others. Optimum temperatures for seed germination and seedling growth ranged from 20 to $25^{\circ}C$ and especially temperature at $25^{\circ}C$ improved seed germinations of Ledebouriella seseloides, Angelica dahurica and Ligusticum acutilobum regardless of light condition.

  • Although immunotherapy has been broadly successful in the treatment of hematologic malignancies and a subset of solid tumors, its clinical outcomes for glioblastoma are still inadequate. The results could be due to neuroanatomical structures such as the blood-brain-barrier, antigenic heterogeneity, and the highly immunosuppressive microenvironment of glioblastomas. The antitumor efficacy of endogenously activated effector cells induced by peptide or dendritic cell vaccines in particular has been insufficient to control tumors. Effector cells, such as T cells and natural killer (NK) cells can be expanded rapidly ex vivo and transferred to patients. The identification of neoantigens derived from tumor-specific mutations is expanding the list of tumor-specific antigens for glioblastoma. Moreover, recent advances in gene-editing technologies enable the effector cells to not only have multiple biological functionalities, such as cytokine production, multiple antigen recognition, and increased cell trafficking, but also relieve the immunosuppressive nature of the glioblastoma microenvironment by blocking immune inhibitory molecules, which together improve their cytotoxicity, persistence, and safety. Allogeneic chimeric antigen receptor (CAR) T cells edited to reduce graft-versus-host disease and allorejection, or induced pluripotent stem cell-derived NK cells expressing CARs that use NK-specific signaling domain can be a good candidate for off-the-shelf products of glioblastoma immunotherapy. We here discuss current progress and future directions for T cell and NK cell therapy in glioblastoma.

  • The purpose of this study is how have the form and theory of the five element theory in the (黃帝內徑) by the investigation of the course of the course of the five element introduced the ancient oriental medicine from ancient oriental philosophy. The following results were obtained. 1. The five elements in (尙書) meaned the uses of water, fire, earth, wood, metal which were important in living. Because these had very important meaning in ancient political and economic society, emphasized to big law(洪範) 2. The five elements in (左傳) and (國語) mean the five uses too, and there are the phases of "five win metal"(火勝金) and "wather win fire"(水勝火), but these only meaned the physical interrelation. 3. In the five circulating factor theory made by Chu Yen(鄒衍) which have the attribute of the five elements, he more reasonably had argued human affairs like that a dynasty become different in step with the circulating five favors. There is the regular annual policy in the (呂氏春秋) which closely connected nature and human living, and attached the various colors, animals, visceras, flavors, sounds, the sexagenary cycle and so on to the five elements. 4. In the (春秋繁露) writed in fore-period of Han(漢) dynasty, the interactions of the five elements are concretely applicated to policy, Dong Jung Soe(童仲舒) had discrived the interactions of the five elements by Dong Lyu Sang Dong theory(同類相動說) and the misfortune theory(災異說), emphasized the sympathy of nature and human. Thought there is many content which are superstitious and contradictory, I concider which that affcted many effects in the formation of five element theory of oriental medicine. In the (淮南子) the order of matters were explained by the five element theory too, as the interrelations of the five elements were explained by the sexagenary ctcle, I assume that the bud of O-Un theory(五運理論). And there was not founded the fullscale intriduction of the five element theory in the Ma Wang Tye(馬王堆) excavated finds, the Mu Yyi medical writings formed the dynasty(武威漢代醫簡) and the documents about Pyun Jak(偏鵲) and Sun U Ie(淳于意). 5. The application of the five element theory in the (Whang Di Nei Qing) (黃帝內徑) is devided into the attachement to the five elements, the interelations of the five elments, and Un Gi theery(運氣論). In the attachment to the five elemeant theory, it made the attachment of the five viseras of (今文尙書) party a standard and attached the sections of a human body, the whole internal organs of sense, the five colors, the five flavors and the five sounds and so on to the five elements. It put to use by means of the apllivation of the interrelation of the five elements in the transferations of the diseases and the relative severeness of a disease in step with change of time and season. Un Gi theory(運氣論) which synthesized by the attachment to the five elements, the inter-relations of the five elements and the climate which observerd from ancient times systematically argued the effects of weather to human. 6. The application of the five elements theory in (黃帝內徑) have the significant what had get rid of irrational factors like that the emotion and action of human could to influense the weather, what had been formes more rational thingking by the obesrvation of human and nature. It is required more reserches about the possibility of the formation of the doctrinal faction bt the geographical effect of the Yon, Je(燕,薺) region, the application of the five element theory in other ancient medical books and the relationship of the five element theory and Yin Yang(陰陽)

  • Literature on the relationship between recurrent urinary tract infections and urinary bladder carcinoma risk has been inconsistent. Therefore, we carried out this systematic review of observational studies to ascertain if there is any association between chronic urinary tract infection and urinary bladder carcinoma. A total of 10 databases were searched using Boolean: CINAHL, PUBMED, Google Scholar, Medline, Science Direct, SCIRUS, Cochrane, UK PubMed central, NHS evidence and WHO-website. The search yielded an initial hit of 3,518 articles and after screening and critical appraisal, seven studies were included for this review. Four articles reported an association between chronic urinary tract infections and bladder cancer while three concluded a weak or no association at least in one gender. Main findings in this review were that most of the studies reported an association between chronic urinary tract infections and bladder cancer risk. However, inferences about the causal association between chronic urinary tract infections and bladder cancer risk should be drawn cautiously considering the methodological limitations of case-control studies included in this review. Therefore, more empirical evidence is needed to determine the causal nature of relationships between chronic urinary tract infections and bladder cancer risk.

  • Effective Microorganisms (EM), a fermented medium developed by Professor Higa at the University of the Ryukyus, is a mixed culture containing dozens of microorganisms which are beneficial to nature including people, animals, plants and many microbial species in environment. EM is known to contain more than 80 kinds of anaerobic or aerobic microbes including photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, fungi and so on, with yeast, lactic acid bacteria and photosynthetic bacteria as the main species of EM. Antioxidant effect generated by the concert of complex coexistence and coprosperity among these microbes is considered to be the main source of EM benefits. Currently, EM is earning an increasing attention with applications in agriculture, forestry, animal husbandry, fisheries, environment and medicine among others. At the same time, however, a quantitative interpretation of EM system based on a mixed culture model needs efforts from biochemical engineers for efficient production and further promotion of EM. In this paper, we describe the functions of major microbes in EM and current researches and applications of EM in agriculture, forestry, animal husbandry, fisheries, environment and medicine.

  • 위암은 최근에 균일한 성격의 단일 질환이 아니라, 매우 이질적인 질환으로 인식되고 있다. 수술이 불가능한 진행성 또는 전이성 위암의 경우 일반적으로 완치가 불가능하며 항암치료를 하지 않는 경우 중앙 생존기간이 3-6개월 정도로 알려져 있다. 따라서 항암치료를 하는 경우가 최선의 지지 치료에 비하여 삶의 질이나 생명연장의 측면에서 우월함을 이미 여러 연구를 통해서 확인되고 있다. 지난 기간 동안 다양한 항암치료가 진행성 위암의 치료에 적용되었고, 최근에 여러 표적 치료와 면역치료가 도입되고 있으나, 여전히 다른 암종에 비하여 진행성 위암환자에서는 현저한 생명연장은 아직 저조하고 답보 상태에 있다. 그러나 향후 위암의 분자생물학적인 특성이 자세히 알려지면서 이러한 어려움들은 극복될 것으로 기대된다.

  • The aims of this article is to examine that Daegeum Sanjo Rhythm (DSR) compare with Jinyang-jangdan and Jajinmori-jangdan on music therapy. Daegeum has the largest range of notes in wind instruments through Korean music. Jangdan is the essential element of rhythm in Korean music. Just as human body sound and resonant with their rhyme and meters, jangdan has its own rhythms of physical structures and sequence and repeat. Jinyang-jangdan, which is close to western minor code, expresses heartbreaking grief and great mourning feeling, so it makes one feel the catharsis through that rhythm. Jinyang-jangdan of daegeum music may be slow, but it can be sublimated into grim music for human. So, people overcome the sadness through grim music. On the other hand, jajinmori-jangdan gives charm and gaiety to people and to everything. So, it is exciting that it's often performed in festival and parade. Rhythmical music is a tool to improve the well-being of humanity and increase our life choices. Therefore, music therapy surely needs both influences of daegeum sanjo music regardless of the rhythm. Because, daegeum sanjo music is nature-friendly music of the rhythm.
