Introduction: In our previous studies, we isolated porcine skin-derived mesenchymal stem cells (pSDMSCs) from the ears of adult miniature pigs and evaluated the pluripotency of these pSDMSCs based on expressions of transcription factors, such as Oct-4, Sox-2, and Nanog. Moreover, the characteristic of mesenchymal stem cells was revealed by the expression of various mesenchymal stem cell markers, including CD29, CD44, CD90, and vimentin. The aim of this study was to evaluate in vivo osteogenesis after maxillary sinus lift procedures with autogenous pSDMSCs and scaffold. Materials and Methods: The autogenous pSDMSCs were isolated from the 4 miniature pigs, and cultured to 3rd passage with same methods of our previous studies. After cell membranes were labeled using a PKH26, $1{\times}10^{7}$ cells/$100{\mu}L$ of autogenous pSDMSCs were grafted into the maxillary sinus with a demineralized bone matrix (DBM) and fibrin glue scaffold. In the contralateral control side, only a scaffold was grafted, without SDMSCs. After two animals each were euthanized at 2 and 4 weeks after grafting, the in vivo osteogenesis was evaluated with histolomorphometric and osteocalcin immunohistochemical studies. Results: In vivo PKH26 expression was detected in all specimens at 2 and 4 weeks after grafting. Trabecular bone formation and osteocalcin expression were more pronounced around the grafted materials in the autogenous pSDMSCs-grafted group compared to the control group. Newly generated bone was observed growing from the periphery to the center of the grafted material. Conclusion: The results of the present study suggest that autogenous skin-derived mesenchymal stem cells grafting with a DBM and fibrin glue scaffold can be a predictable method in the maxillary sinus floor elevation technique for implant surgery.

Cytomegalovirus (CMV)는 신 이식 후 발생하는 감염의 가장 흔한 원인으로, 예방요법과 새로운항 바이러스 제제의 도입에도 불구하고 심각한 결과를 초래하며, 거부반응을 촉진한다는 의견도 제시되고 있다. 저자들은 이식 전 CMV 양성이었던 환아에서 후기 CMV 질환이 발병한 증례를 보고하고자 한다. 이식 6개월 후 mycophenolate mofetil ((MMF)을 투여한 후로 설사와 복통을 호소하던 환아는 이식 후 8개월에 소장이 파열되었다. 환아는 6주간의 치료후에 호전되었다. CMV감염의 위험 인자로 MMF의 역할에 대해서는 더 논의가 필요하나, MMF 투여 시이식 후 바이러스 감염에 대한 주의와 주기적인 추적 관찰이 필요하다.

Objective : Microvascular decompression (MVD) for hemifacial spasm (HFS) involving the vertebral artery (VA) can be technically challenging. We investigated the therapeutic effects of a bioglue-coated Teflon sling technique on the VA during MVD in 42 cases. Methods : A bioglue-coated Teflon sling was crafted by the surgeon and applied to patients in whom neurovascular compression was caused by the VA. The radiologic data, intra-operative findings with detailed introduction of the procedure, and the clinical outcomes of each patient were reviewed and analyzed. Results : The 42 patients included in the analysis consisted of 22 females and 20 males, with an average follow-up duration of 76 months (range 24-132 months). Intraoperative investigation revealed that an artery other than the VA was responsible for the neurovascular compression in all cases : posterior inferior cerebellar artery (PICA) in 23 patients (54.7%) and anterior inferior cerebellar artery (AICA) in 11 patients (26.2%). All patients became symptom-free after MVD. Neither recurrence nor postoperative neurological deficit was noted during the 2-year follow-up, except in one patient who developed permanent deafness. Cerebrospinal fluid (CSF) leak occurred in three patients, and one required dural repair. Conclusion : Transposition of the VA using a bioglue-coated Teflon sling is a safe and effective surgical technique for HFS involving the VA. A future prospective study to compare clinical outcomes between groups with and without use of this novel technique is required.

Cancer preventive activities of green tea and its main constituent, (-)-epigallocatechin gallate (EGCG) have been extensively studied by scientists all over the world. Since 1983, we have studied the cancer chemopreventive effects of EGCG as well as green tea extract and underlying molecular mechanisms. The first part of this review summarizes groundbreaking topics with EGCG and green tea extract: 1) Delayed cancer onset as revealed by a 10-year prospective cohort study, 2) Prevention of colorectal adenoma recurrence by a double-blind randomized clinical phase II trial, 3) Inhibition of metastasis of B16 melanoma cells to the lungs of mice, 4) Increase in the average value of Young's moduli, i.e., cell stiffness, for human lung cancer cell lines and inhibition of cell motility and 5) Synergistic enhancement of anticancer activity against human cancer cell lines with the combination of EGCG and anticancer compounds. In the second part, we became interested in cancer stem cells (CSCs). 1) Cancer stem cells in mouse skin carcinogenesis by way of introduction, after which we discuss two subjects from our review on human CSCs reported by other investigators gathered from a search of PubMed, 2) Expression of stemness markers of human CSCs compared with their parental cells, and 3) EGCG decreases or increases the expression of mRNA and protein in human CSCs. On this point, EGCG inhibited self-renewal and expression of pluripotency-maintaining transcription factors in human CSCs. Human CSCs are thus a target for cancer prevention and treatment with EGCG and green tea catechins.

Introduction: In order to control the tobacco scourge, an array of measures is required. Among them is focusing on adolescent relationships as it has been shown that being in a close relationship with a smoker or a non smoker will in the long run be a major factor in deciding whether the individual adopts smoking for initial non-smokers or ceases the habit for initial smokers. Objectives: To assess the attitude of youth towards other smokers and towards marrying a smoker. Materials and Methods: A cross-sectional study was carried out among 415 students from five universities in the United Arab Emirates (UAE). Self-administered structured questionnaires were used for data collection. The Chi square test was used to detect significant differences between frequencies. Results: Of the 415 participants who provided their gender information, 99 (24%) were males and 314 (76%) were females. Of all the participants, 83.5% were not willing to marry smokers, while 16.5% were willing. Of those whose parents smoked (106) 68% did not like it when their parents smoked, 13.6% had no opinion, 17.5% did not mind, while the other 1% had other thoughts. Of those whose close friends smoked, 43.4% did not like it, 16.2% did not have any opinion, 36.9% did not mind while 3.5% had other thoughts. Conclusion: Most participants, both males and females are not willing to marry smokers and prefer to have non-smokers as spouses. Also, smokers are seen as less attractive by both genders in contrast to what appears as popular beliefs amongst youngsters and what is depicted in tobacco advertisements. Tobacco control activities can be undertaken in the community and colleges by incorporating students as facilitators.

Integrated control strategies are important for sustainable control of schistosomiasis and soil-transmitted helminthiasis, despite their challenges for their effective implementation. With the support of Good Neighbors International in collaboration with National Institute of Medical Research, Mwanza, Tanzania, integrated control applying mass drug administration (MDA), health education using PHAST, and improved safe water supply has been implemented on Kome Island over 5 years for controlling schistosomiasis and soil-transmitted helminths (STHs). Baseline surveys for schistosomiasis and STHs was conducted before implementation of any integrated control strategies, followed by 4 cross-sectional follow-up surveys on randomly selected samples of schoolchildren and adults in 10 primary schools and 8 villages, respectively, on Kome islands. Those follow-up surveys were conducted for impact evaluation after introduction of control strategies interventions in the study area. Five rounds of MDA have been implemented from 2009 along with PHAST and improved water supply with pumped wells as other control strategies for complementing MDA. A remarkable steady decline of schistosomiasis and STHs was observed from 2009 to 2012 with significant trends in their prevalence decline, and thereafter infection rate has remained at a low sustainable control. By the third follow-up survey in 2012, Schistosoma mansoni infection prevalence was reduced by 90.5% and hookworm by 93.3% among schoolchildren while in adults the corresponding reduction was 83.2% and 56.9%, respectively. Integrated control strategies have successfully reduced S. mansoni and STH infection status to a lower level. This study further suggests that monitoring and evaluation is a crucial component of any large-scale STH and schistosomiasis intervention.

Objectives : The purpose of this study was to propose the utilization plan of Ryodoraku in the U-health care systems. Methods : Computerized literature searches were performed for Ryodoraku related articles using the following databases: KISS, RISS, DBPIA, NDSL from 1990 to Oct 2010. Search terms were '양도락' or 'Ryodoraku' or 'U-health'. Due to Ryodoraku coming from Japan, additional literature review(articles published by 2008) on Japanese journal of Ryodoraku medicine was done for compensation. Results : 1. Introduction of U-health : As rapid progress of population aging and strong interest in health, the demand for the traditional Korean medical service is increasing. Until now healthcare service has provided post treatment by face-to-face manner. But according to related researches, proactive treatment is resulted to be more effective for preventing diseases. Particularly, the existing healthcare services have limitations in preventing and managing chronic geriatric degenrative diseases such as metabolic syndrome, CVA, coronary heart diseases, parkinson's diseases, degenerative joint disease, spondylosis, etc., because the cause of the above is complex and even related to life habit. As the advent of ubiquitous technology, patients with the chronic geriatric degenrative diseases can improve life habit such as poor eating habits and physical inactivity without the constraints of time and space through u-healthcare service. Therefor, lots of researches for u-healthcare service focus on providing the personalized healthcare service for preventing and managing that. To cope with this situations, The concept of u-healthcare service should be adopted in the traditional korean medicine and diagnostic devices suitable for it should be also devised and developed based on traditonal korean medine. 2. Review of existing Ryodoraku related articles for applying to U-health : articles investigating feasibility applying Ryodoraku to meridian diagnosis and raising problems of it, articles providing recent research trends of Ryodoraku, Ryodoraku related articles considering usefulness for U-health, and articles confirming the repeatability and reproducity of Ryodoraku were included. Based on the review of the above Ryodoraku related articles, several application of Ryodoraku in the U-health care system. Conclusions : To make preparations for the increasing need of traditional Korean medicine due to rising morbidity rate of chronic geriatric degenerative diseases, it is necessary to appropriately apply Ryodoraku to the U-health care system. The application of Ryodoraku is as follows. 1. To use Ryodoraku additionally to the established diagnostic device of metabolic syndrome, CVA, coronary heart diseases, parkinson's diseases, degenerative joint disease, spondylosis. 2. To apply Ryodoraku to the symptoms or diseases having a tendency to be diagnosed by correlation between the affected meridian and the lesion such as headache, nuchal pain, shoulder pain, low back pain, sciatica, HNP, etc. 3. To secure the repeatability and reproducity of Ryodoraku. 4. To devise and develop Ryodoraku appliance in order to overcome the known drawbacks and to improve error of measurement.
