This study is a quasi-experimental research using non-equivalent control group pre-post design in order to understand the effectiveness of biomedical ethics education using movies. This study selected the first-year 45 students and 63 students who were attending at two 4-year-course nursing colleges as an experimental group and control group, respectively. Then, this study provided the experimental group with the lecture on biomedical ethics for 16 weeks using the movie related to the ethical issues covering 10 areas. Data collection was done for 5 days from August 26, 2013 until December 5, 2013, and conducted pre-post questionnaire survey on the 1st week session and 16th session after explaining there search purpose and getting a written agreement from the subjects. As a result of analysis of the collected data using SPSS Statistics 18, it was found that students' average point of biomedical ethics awareness improved to 3.31 from 3.07; additionally, in the analysis of the data by sub-area, the point in artificial abortion improved to 3.69 from 3.08; artificial insemination from 2.99 to 3.57; fetal diagnosis from 3.10 to 3.45; a newborn's right to life from 3.39 to 3.55 and organ transplant from 3.26 to 3.53, respectively(P<.001). On the contrary, the research results showed that there was no change in the point of the mercy-killing, brain death, and human biotechnology areas, respectively(p>.05). Conclusively, movie-aided education could be diversely used for nursing education provided movie contents should be in accord with a lecture subject in a way that can arouse students' interest and concern, and improve educational satisfaction.

This study was conducted to investigate the changes of heavy metals in percolated water of paddy soil in which rice was cultivated in conditions of 0%, 5%. 30% addition of bituminous and anthracite fly ash respectively. In cultivated plot, the contents of Fe in percolated water increased gradually during the cultivation. But there was no sharp difference of Fe contents in fly ash treated plots. The contents of Mn in percolated water increased gradually during the cultivation and was high in the cultivated plot. But difference in the contents of Mn among plots not clear. The contents of Zn in percolated water was highest during 20-25 days in the cultivation, thereafter decreased gradually. The fly ash did not cause to increase the contents of Zn in percolated water. The contents of Cu in percolated water decreased through the cultivation. Fly ash treatment did not cause to increase the contents of Cu in percolated water. The contents of Pb in percolated water decreased gradually over the cultivation. Fly ash treatment did not largely influence to Pb percolation. In mid-July. Pb did not almost appeared in percolated water. The contents of Cd was highest about 15 days of the transplant, thereafter decreased gradually. After 40 day of the cultivation, leach of Cd stopped. When fly ashes were applied in paddy soil, the contents of heavy metals in percolated water was not so much compared with control plot. It seems that originally low contents of heavy metals in fly ash and decrease in solubility of heavy metals in a relatively high soil pH make it possible to use fly ash as a soil conditioner.

Purpose: To investigate the influence of exogenous p53 upregulated modulator of apoptosis (PUMA) expression on cell proliferation and apoptosis in human non-small cell lung cancer A549 cells and transplanted tumor cell growth in nude mice. Materials and Methods: A549 cells were divided into the following groups: control, non-carrier (NC), PUMA (transfected with pCEP4-(HA) 2-PUMA plasmid), DDP ($10{\mu}g/mL$ cisplatin treatment) and PUMA+DDP (transfected with pCEP4-(HA)2-PUMA plasmid and $10{\mu}g/mL$ cisplatin treatment). The MTT method was used to detect the cell survival rate. Cell apoptosis rates were measured by flow cytometry, and PUMA, Bax and Bcl-2 protein expression levels were measured by Western blotting. Results: Compared to the control group, the PUMA, DDP and PUMA+DDP groups all had significantly decreased A549 cell proliferation (p<0.01), with the largest reduction in the PUMA+DDP group. Conversely, the apoptosis rates of the three groups were significantly increased (P<0.01), and the PUMA and DDP treatments were synergistic. Moreover, Bax protein levels significantly increased (p<0.01), while Bcl-2 protein levels significantly decreased (p<0.01). Finally, both the volume and the weights of transplanted tumors were significantly reduced (p<0.01), and the inhibition ratio of the PUMA+DDP group was significantly higher than in the single DDP or PUMA groups. Conclusions: Exogenous PUMA effectively inhibited lung cancer A549 cell proliferation and transplanted tumor growth by increasing Bax protein levels and reducing Bcl-2 protein levels.

The current treatment of extensive meniscal injuries has resulted in numerous investigations and clinical trials to restore normal meniscal functions. A cryopreserved meniscal allograft transplantation is one of the successful methods available to restore the meniscus. All the procedures of 26 cases were performed in an minimal open fashion, though initial four cases were done with the aid of arthroscope. In all of the grafts, we used a bone bridge which was attached to meniscus for better stability and healing. Anterior cruciate ligament reconstructions were also performed simultaneously with the meniscal procedures. We attempted to minimize articular cartilage by employing so called the "Key-hole technique" for the medial meniscus transplantation. First, the meniscal cartilage bone bridge was shaped into a cylinder and a bone tunnel was made just beside the medial border of the anterior criciate ligament insertion of the recipient knee joint, and the bone bridge of the meniscal cartilage was push to press-fit. The inserted meniscal cartilage was sutured by the usually employed technique under arthroscopic control. The lateral meniscus was shaped different to the medial meniscus in that the bone bridge was semicylindrical and the bone trough was made beside the lateral border of the anterior criciate ligament insertion of the recipient knee joint. The meniscus was put into the bone trough and the leading suture was extracted anterior to the tibia and tied the knot. The inserted meniscus was sutured in the same manner as the medial meniscus transplantation. By the above described method, the authors were able to minimize the articular cartilage invasion and transplant the meniscus with relative accuracy.

Unerupted maxillary anterior teeth is not a common case, However it may present practitioners with management problem. The cause of impaction is considered to be multifactorial, and local cause is the most common. These impacted teeth require surgical intervention, removal, transplantation, or surgical exposure, with or without orthodontic traction to align the malpositioned tooth. The preferred option is surgical exposure and orthodontic correction. Surgical intervention and orthodontic correction should not be delayed to avoid unnecessary difficulties in aligning the tooth in the arch. Surgical exposure should be performed with the intent of providing sufficient attached gingiva rather than simply uncovering the crown, which results in only alveolar mucosal attachment. Attached gingiva is essential to secure the gingival tissues to the adjacent teeth at the dentogingival junction. Thus preventing loss of periodontal tissues as a result of the pull of the surrounding soft tissues and facial muscles. Labially impacted maxillary anterior teeth uncovered with an apically positioned flap technique have more un- esthetic sequelae than those uncovered with a closed-eruption technique. In the case of severly displaced impacted teeth, autotransplantation ensures preservation of the alveolar bone and will facilitate future placement of an osseointegrated implant once growth has ceased or if ankylosis/resorption of the transplant occurs.

Bronchiolitis obliterans (BO) is a nonspecific inflammatory injury affecting primarily the small airways. Its inflammatory process is characterized by fibrotic obliteration of the lumen of bronchioles. BO can be idiopathic or associated with connective tissue disease, inhaled toxins, infections, drugs, and chronic graft-versus-host-disease (GVHD). Pulmonary complications occur in 40~60% of patients who undergo allogeneic bone marrow transplantation (BMT), causing 10~40% of transplant-related deaths. BO is a characteristic pulmonary complication which occurs usually within a few years after BMT. Documented complications of BO include air-leak syndromes such as pneumomediastinum, subcutaneous emphysema and pneumothorax. We report a case of a 30-year-old male patient with BO due to chronic GVHD after allogenic BMT who presented with recurrent bilateral pneumothoraces.

Cyclosporine (CsA) has become well established as a potent immunosuppressive agent in the renal transplantation. However, therapy is complicated by large intraindividual and interindividual variability in pharmacokinetics of CsA and frequent undesirable clinical outcomes such as graft rejection and nephrotoxicity. The objective of this study was to determine the CsA trough blood concentrations that were associated with acute graft rejection and renal toxicity in renal transplant patients. Also, the ability of the current recommendation of therapeutic range for CsA to prevent graft rejections and CsA-associated renal toxicity was assessed. The clinical courses of the patients on CsA as an immusuppressive agent for preventing the graft rejection with renal ransplantation performed at Seoul National University Hospital from January 1995 to September 1998 were retrospectively reviewed. Total of 78 patients were included and three of them were retransplantation cases. Twenty-two acute episodes of rejection were identified, but only 16 episodes were clinically significant. Of these all the episodes occurred during the first month after transplantation except one. Mean daily doses of CsA were $427.2\pm72.1,\;352.6\pm56.8,\;308.62\pm48.3\;and\;268.47.1\;mg$ at posttransplant 1, 3, 6, and 12 months, respectively. Mean CsA whole blood though levels were $259.8\pm36.2,\;238.5\pm39,\;200.8\pm45.8\;and\;161.9\pm25.8\;ng/ml$ at posttransplant 1, 3, 6 and 12 months, respectively. Mean daily doses/weight were $7.9\pm1,\;6.4\pm1,\;5.3\pm0.7\;and\;4.6\pm0.7\;mg/kg$ at posttransplant 1, 3, 6 and 12 months, respectively. CsA doses decreased significantly as months progressed (p<0.001). During the first month after transplantation, only $12.5\%$ of the patients in rejection group had CsA concentration in therapeutic range, and 87.5, 93.8, and $100\%$ were within the therapeutic range at posttransplant 3, 6, and 12 months, respectively. These results suggested that CsA concentrations of $250\sim300\;ng/ml$ might be appropriate for preventing the acute rejection during the first posttransplant month.

Purpose: The survival rate for childhood acute lymphoblastic leukemia (ALL) has improved significantly. However, overall prognosis for the 20 to 25% of patients who relapse is poor, and allogeneic hematopoietic stem cell transplantation (HSCT) offers the best chance for cure. In this study, we identified significant prognostic variables by analyzing the outcomes of allogeneic HSCT in ALL patients in second complete remission (CR). Methods: Fifty-three ALL patients (42 men, 79%) who received HSCT in second CR from August 1991 to February 2009 were included (26 sibling donor HSCTs, 49%; 42 bone marrow transplantations, 79%). Study endpoints included cumulative incidence of acute and chronic graft-versus-host disease (GVHD), relapse, 1-year transplant-related mortality (TRM), disease-free survival (DFS), and overall survival (OS). Results: Cumulative incidences of acute GVHD (grade 2 or above) and chronic GVHD were 45.3% and 28.5%, respectively. The estimated 5-year DFS and OS for the cohort was $45.2{\pm}6.8%$ and $48.3{\pm}7%$, respectively. Only donor type, i.e., sibling versus unrelated, showed significant correlation with DFS in multivariate analysis ($p$=0.010). The rates of relapse and 1 year TRM were $28.9{\pm}6.4%$ and $26.4{\pm}6.1%$, respectively, and unrelated donor HSCT ($p$=0.002) and HLA mismatch ($p$=0.022) were significantly correlated with increased TRM in univariate analysis. Conclusion: In this single institution study spanning more than 17 years, sibling donor HSCT was the only factor predicting a favorable result in multivariate analysis, possibly due to increased TRM resulting from unrelated donor HSCT.

To verify suitability of the developed nutrient solution for fertigation culture of cucumber, chemical changes of soil, growth characteristics and yield of cucumber as affected by conventional fertigation method (Control), the developed nutrient solution for fertigation culture (DNF) and Yamasaki cucumber recipe (YCR) were investigated. At 48 days after transplant, photosynthetic and transpiration rate of cucumber leaves were the highest in 3/2 strength of DNF and 1/2 strength of YCR, but not different with the Control, in the later growing period photosynthetic rate was the highest in 3/2 strength of DNF and YCR and was clearly different with the Control, transpiration rate was the highest in 3/2 strength of DNF and 1/2, 1 strengths of YCR. The growth and yield of cucumber, nutrient elements of cucumber leaves except for calcium were more in DNF and YCR than in the Control. Compared with pre-treated loam soil, pH of the soil was low and electric conductivity was high in all treatments, amounts of accumulated phosphorus, potassium, calcium, and magnesium were much in the higher concentrations per the kinds of nutrient solutions. From the above results, it was considered that the developed nutrient solution has suitability as nutrient solution for fertigation culture of cucumber.
