Objective : This study aimed to compare the clinical and radiologic outcomes of patients with subaxial cervical injury who underwent anterior cervical discectomy and fusion (ACDF) with autologous iliac bone graft or polyetheretherketone (PEEK) cages using demineralized bone matrix (DBM). Methods : From January 2005 to December 2010, 70 patients who underwent one-level ACDF with plate fixation for post-traumatic subaxial cervical spinal injury in a single institution were retrospectively investigated. Autologous iliac crest grafts were used in 33 patients (Group I), whereas 37 patients underwent ACDF using a PEEK cage filled with DBM (Group II). Plain radiographs were used to assess bone fusion, interbody height (IBH), segmental angle (SA), overall cervical sagittal alignment (CSA, C2-7 angle), and development of adjacent segmental degeneration (ASD). Clinical outcome was assessed using a visual analog scale (VAS) for pain and Frankel grade. Results : The mean follow-up duration for patients in Group I and Group II was 28.9 and 25.4 months, respectively. All patients from both groups achieved solid fusion during the follow-up period. The IBH and SA of the fused segment and CSA in Group II were better maintained during the follow-up period. Nine patients in Group I and two patients in Group II developed radiologic ASD. There were no statistically significant differences in the VAS score and Frankel grade between the groups. Conclusion : This study showed that PEEK cage filled with DBM, and plate fixation is at least as safe and effective as ACDF using autograft, with good maintenance of cervical alignment. With advantages such as no donor site morbidity and no graft-related complications, PEEK cage filled with DBM, and plate fixation provide a promising surgical option for treating traumatic subaxial cervical spine injuries.

2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin (TCDD) are well known as the most toxic environmental compound in these days. Many researches are reported that dioxin produces multiple toxic effects, such as endocrine toxicity, reproductive toxicity, immunotoxicity and cancer. In this study, we carried to discover novel evidence for previously unknown gene expression patterns in human exposed to dioxin by using radioactive cDNA microarray. 548 workers who were divided into experimental and control groups according to their urinary Naphthol levels were enrolled in our study. Blood mRNA in human was isolated, and the gene expression profiles were analyzed by cDNA microarray. Gene expression analysis identified 52 genes which exhibited a significant change. In our study, most notably, genes involved in cell cycle, cell proliferation, signal transduction and apoptosis in human exposed to dioxin, such as CCND3, TSHR, and EFRN5, were up-regulated. In the current study, we observed gene expression of people that are exposed to dioxin using radioactive cDNA microarray. Through these results, we suggest when objects are exposed to toxic compounds, such as dioxin, the radioactive cDNA microarray may be using in sensitively detecting of cancerous change.

The purpose of this study was to investigate the daily life experiences of medical students and to explore gender differences in these experiences using the Experience Sampling Method (ESM) as the method. The instrument, the Experience Sampling Form (ESF), consisted of questions on the external and internal experiences of the respondents. Data were collected from 2,035 ESFs by 91 students (male=52, female=39) at three medical schools for one week. The data was analyzed using the statistical tests of the t-test and ${\chi}^2$ test. Activity places were significantly different by gender (${\chi}^2=16.576$, p=.001). Males spent more time in learning places such as schools, libraries, etc., whereas females spent their time in personal places, including their homes, dormitories, etc. Males undertook more learning activities than did females, and females undertook more social/leisure activities and basic life activities than did male students (${\chi}^2=18.753$, p=.001). They were in a learning place and performing learning activities. There were significant perceptual differences between males and females about their flow levels, competency levels, and difficulty levels, based on the activity type. These results can help us to understand the daily lives of medical students and can be useful in developing counseling programs and educational activities for students.

Background: In radiation therapy, estimation of surface doses is clinically important. This study aimed to obtain an analytical relationship to determine the skin surface dose, kerma and the depth of maximum dose, with energies of 6 and 18 megavoltage (MV). Materials and Methods: To obtain the dose on the surface of skin, using the relationship between dose and kerma and solving differential equations governing the two quantities, a general relationship of dose changes relative to the depth was obtained. By dosimetry all the standard square fields of $5cm{\times}5cm$ to $40cm{\times}40cm$, an equation similar to response to differential equations of the dose and kerma were fitted on the measurements for any field size and energy. Applying two conditions: a) equality of the area under dose distribution and kerma changes in versus depth in 6 and 18 MV, b) equality of the kerma and dose at $x=d_{max}$ and using these results, coefficients of the obtained analytical relationship were determined. By putting the depth of zero in the relation, amount of PDD and kerma on the surface of the skin, could be obtained. Results: Using the MATLAB software, an exponential binomial function with R-Square >0.9953 was determined for any field size and depth in two energy modes 6 and 18MV, the surface PDD and kerma was obtained and both of them increase due to the increase of the field, but they reduce due to increased energy and from the obtained relation, depth of maximum dose can be determined. Conclusions: Using this analytical formula, one can find the skin surface dose, kerma and thickness of the buildup region.

Objectives : Korean medicine practice is not specifically described in medical law, and then has always been a quarrel. So far The criteria for judgment in Korean Medicine Doctor's Medical Devices Using should clinically prove it only by Korean medicine theory and academic Traditionally descending from old ancestors. Comprehensively review of Korean Medicine Doctor's Medical Devices Using and Duty of Care, and then present a new understandings to determine future Korean Medicine Practice. Method : An existing court cases of Korean Medicine Doctor's Medical Devices Using and Duty of Care were reviewed. After reviewing various papers published for several years, various opinions were reviewed and suggested. Results : The range of Korean Medicine Doctor's Medical Devices Using has changed since the 1951 National Medical Law stipulated Korean medicine as medical professionals. The issue of the recent ruling that distinguishes medical practice from Korean medicine practice were condensed into what emphasis to interpret amongst 1) The basic principles of learning, 2) Curriculum and professionalism, 3) Risks. The Constitutional Court's ruling was important in order of 'Risk', 'curriculum and expertise', and 'basic principles of learning.' A duty of Care means an obligation to pay attention to something. A duty of Care does not mean a "highest level," but requires a "best care" and does "best under given conditions." Even in the duty of Care, Because Korean medicine has a purpose to protect and promote the health of the people, Some standards of western medicine have to be adapted to the current general medical technology. Korean Medicine doctors can recognize the duty of care in the "some basic range" of knowledge belonging to western medicine. Conclusions : The interpretation of Korean Medicine practice are currently in compatible the argument that should clearly divide Korean medicine from Western medicine, and that should be changed in light of the changing medical environment. Therefore If Korean medicine's standard is applied to the extent to which Korean Medicine doctors are educated, it is necessary to define a new definition to actively interpret Korean Medical practice. The academic basis of Korean medicine and the level of Korean medicine practice based on the books that are traditionally available, and then current textbooks of Korean Medicine College, Korean Medicine Clinical Care Guidelines, and classification of Korean standard medical practices should be standardized. Increasingly, Korean Medicine practice should be interpreted according to reality, focusing on protecting and promoting the health of the people rather than academic differences.
