Between January 1990 and February 1991, ureteroscopic removal of ureteral stone was performed in 40 cases at outpatient department under local anesthesia(36 cases) and epidural anesthesia(4 cases). The results were as follows. The success rate of ureteral stone removal was 82.1% (32 among 39 cases) in lower ureter, 86.7 %(26 among 30 cases) in female and 70.0%(7 among 10 cases) in male. Anesthetic methods were local(36 cases), and epidural(4 cases), Mean duration of hospitalization was 1.4 days(0-7 days). The associated complication rate was low, with most patients being treated conservatively. Therefore, we believe that the ureteroscopic stone removal at outpatient department can be done safely if we select patients properly(especially women). have adequate equipment and execute properly the basic technique.

The skin, the largest organ in the body, undergoes age-related changes influenced by both intrinsic and extrinsic factors. The primary external factor is photoaging which causes hyperpigmentation, uneven skin surface, deep wrinkles, and markedly enlarged capillaries. In the human dermis, it decreases fibroblast function, resulting in a lack of collagen structure and also decreases keratinocyte function, which compromises the strength of the protective barrier. In this study, we found that treatment with γ-aminobutyric acid (GABA) had no toxicity to skin fibroblasts and GABA enhanced their migration ability, which can accelerate skin wound healing. UVB radiation was found to significantly induce the production of matrix metalloproteinase 1 (MMP-1), but treatment with GABA resulted in the inhibition of MMP-1 production. We also investigated the enhancement of filaggrin and aquaporin 3 in keratinocytes after treatment with GABA, showing that GABA can effectively improve skin moisturization. In vivo experiments showed that oral administration of GABA significantly improved skin wrinkles and epidermal thickness. After the intake of GABA, there was a significant decrease observed in the increase of skin thickness measured by calipers and erythema. Additionally, the decrease in skin moisture and elasticity in hairless mice exposed to UVB radiation was also significantly restored. Overall, this study demonstrates the potential of GABA as functional food material for improving skin aging and moisturizing.

PURPOSE: The purpose of this study is to understand and analyse the actual education environment of the subject, life science, and how it is taught in high school, and thereby make a realistic assessment of whether a medical life science experience program is necessary. METHODS: The test method to assess the actual curriculum was developed by Life Science teachers, medical school faculty and education specialists. The subject was divided into 4 areas consisting of 6 items each. Our survey was mailed out. The analysis consisted of frequency analysis, chi-square analysis, correlation analysis, and variance analysis using SPSS 13.0 for Windows. RESULTS: Over 90% of Life Science class teachers agreed that teaching should be done through lectures and lab experiments in parallel. However, currently the class is heavily lecture-oriented due to the lack of lab facilities, the lack of budget and the difficulty of organizing lab courses. Due to the nature of the subject, lab experiments are crucial. Therefore, it is recommended that a biomedical science experience program be included in the curriculum. This program should be offered during vacation and geared toward high school freshmen and sophomore students. CONCLUSION: This research clearly showed the need to develop a high school biomedical science experience program. In order for the program to be successful, one must take into consideration the safety of experiments, the capability of the instructors, the development of a variety of experiments, the accessibility of the location of the lab, securing interest in education at a community level and the compilation of an experience program at every educational level.

Insulin therapy is indicated in the treatment of gestational diabetic women and overt diabetic pregnant women for hyperglycemia after failure to respond to the diets and exercise regimens. The insulin is administered to mimic normal pancreatic function. The normal pancreas secretes 50% of the total daily insulin as mealtime boluses. This delivery may be mimicked by four-injection-per-day of combination of NPH and regular insulin (RI). Hypoglycemia is a well-recognized complication of intensive insulin therapy in patients with Type II diabetes. Recently, it has been reported that insulin-lispro, an analogue of regular human insulin with a peak insulin action achieved with a 1 hour after injection improves postprandial glucose concentration in non-pregnant diabetic patients. Treatment of gestational or diabetic pregnant women with NPH and insulin-lispro has significantly lower postprandial glucose levels without an increase in hypoglycemic events. Here, we report 2 cases of hyperglycemic control with four times daily administration of NPH & insulin-lispro on diabetes in pregnancy, with brief reviews.

PURPOSE: Complex clinical information in cerebral angiointervention unit requires effective management of statistical analysis for the classification of diagnosis and intervention including follow-up data from the interventional treatment. We present an application of Microsoft Access program for the management of patient data in cerebral angiointervention unit which suggests practical methods in recording and analyzing the patient data. MATERIALS AND METHODS: Since January 2002, patient information from cerebral angiointervention was managed by a database with over 4000 patients. We designed a program which incorporates six items; Table, Query, Form, Report, Page and Macro. Patient data, follow-up data and information regarding diagnosis and intervention were established in the Form section, related by serial number, and connected to each other to an independent Table. Problems in running the program were corrected by establishing Entity Relationship (ER) diagrams of Tables to define relationships between Tables. Convenient Queries, Forms and Reports were created to display expected information were applied from selected Tables. RESULTS: The relationship program which incorporated six items conveniently provided the number of cases per year, incidence of disease, lesion site, and case analysis based on interventional treatment. We were able to follow the patients after the interventional procedures by creating queries and reports. Lists of disease and patients files were identified easily each time by the Macro function. In addition, product names, size and characteristics of materials used were indexed and easily available. CONCLUSION: Microsoft Access program is effective in the management of patient data in cerebral angiointervention unit. Accumulation of large amounts of complex data handled by multiple users may require client/sever solutions such as a Microsoft SQL Server.

PURPOSE: The purpose of this study is to determine whether luminacin, a marine microbial extract from the Streptomyces species, has anti-tumor effects on head and neck squamous cell carcinoma (HNSCC) cell lines via autophagic cell death. MATERIALS AND METHODS: Inhibition of cell survival and increased cell death was measured using cell viability, colony forming, and apoptosis assays. Migration and invasion abilities of head and cancer cells were evaluated using wound healing, scattering, and invasion assays. Changes in the signal pathway related to autophagic cell death were investigated. Drug toxicity of luminacin was examined in in vitro HaCaT cells and an in vivo zebrafish model. RESULTS: Luminacin showed potent cytotoxicity in HNSCC cells in cell viability, colony forming, and fluorescence-activated cell sorting analysis. In vitro migration and invasion of HNSCC cells were attenuated by luminacin treatment. Combined with Beclin-1 and LC3B, Luminacin induced autophagic cell death in head and neck cancer cells. In addition, in a zebrafish model and human keratinocyte cell line used for toxicity testing, luminacin treatment with a cytotoxic concentration to HNSCC cells did not cause toxicity. CONCLUSION: Taken together, these results demonstrate that luminacin induces the inhibition of growth and cancer progression via autophagic cell death in HNSCC cell lines, indicating a possible alternative chemotherapeutic approach for treatment of HNSCC.

INTRODUCTION: Comparing with living donor renal transplantation, cadaveric renal transplantation is usually performed as an emergency procedure and has prolonged preservation time and increased incidence of delayed graft function. Korean Network for Organ Sharing (KONOS) was launched from February 2000 to manage the organ transplantation in Korea and expected to increase donor organs supply and an effective organ allocation. PURPOSE: In order to compare the result of cadaveric renal transplantation before and after KONOS system, 108 cadaveric renal transplants performed in Dongsan hospital until October 2003 were reviewed and analyzed. METHODS: Donors and recipients were divided into two groups (group 1; transplantation performed before KONOS, group 2; transplantation after KONOS) and their characteristics and results were analyzed retrospectively. RESULTS: Among donor factors, number of multi-organ procurement increased (23.1% vs 78.6%), and use of inotrophic agent decreased (63% vs 46%) significantly after KONOS, however cold preservation time was not changed even after KONOS system. Procured organs per one donor in our hospital was increased from 2.25 to 2.65. Increased recipient age (from 30.1 to 41.9 years old), more chance to diabetic patient and decreasing number of HLA mismatching (4.6 to 3.9) were considered as a result of KONOS allocation system. However, early results including incidence of acute rejection episode and delayed graft function, and serum creatinine level at the end of one year were no statistic differences. The number of early graft loss were decreased up to 2 years after transplantation. CONCLUSION: Renal transplantation from cadaveric donor after KONOS resulted in lower early graft loss but increased waiting time due to organ shortage is a serious problem to be solved in the future.

BACKGROUND/AIMS: Endoscopic resection is the first-line treatment for rectal neuroendocrine tumors (NETs) measuring < 1 cm and those between 1 and 2 cm in size. However, conventional endoscopic resection cannot achieve complete resection in all cases. We aimed to analyze clinical outcomes of precut endoscopic mucosal resection (EMR-P) used for the management of rectal NET. METHODS: EMR-P was used to treat rectal NET in 72 patients at a single tertiary center between 2011 and 2015. Both, circumferential precutting and EMR were performed with the same snare device in all patients. Demographics, procedural details, and histopathological features were reviewed for all cases. RESULTS: Mean size of the tumor measured endoscopically was 6.8±2.8 mm. En bloc and complete resection was achieved in 71 (98.6%) and 67 patients (93.1%), respectively. The mean time required for resection was 9.0±5.6 min. Immediate and delayed bleeding developed in six (8.3%) and 4 patients (5.6%), respectively. Immediate bleeding observed during EMR-P was associated with the risk of delayed bleeding. CONCLUSIONS: Both, the en bloc and complete resection rates of EMR-P in the treatment of rectal NETs using the same snare for precutting and EMR were noted to be high. The procedure was short and safe. EMR-P may be a good treatment choice for the management of rectal NETs.

BACKGROUND: A reliable rapid assay for hepatitis C virus (HCV) may be helpful in various clinical settings. We evaluated the performance of the OraQuick HCV Rapid Antibody Test (OraSure Technologies Inc., Bethlehem, PA, USA). METHODS: Clinical sensitivity and specificity were evaluated with oral fluids and sera from 137 patients diagnosed with hepatitis C and 300 healthy blood donors in a multi-center collaborative study. The stored sera of 200 proven HCV-infected patients and 200 healthy subjects were also evaluated. Analytical sensitivity was estimated with 4 commercial seroconversion panels and 7 Korean reference panels. The performance of 4 laboratory-based tests (3 chemiluminescence assays and 1 enzyme immunoassay) and 4 rapid test kits was compared. We also assessed the interference due to bilirubin, hemoglobin, lipid, rheumatoid factor, multipara, and several viral infections. RESULTS: The clinical sensitivity and specificity of the OraQuick HCV test using oral fluid were 97.8% (95% confidence interval [CI], 93.2-99.4%) and 100% (95% CI, 98.4-100%), respectively. The clinical sensitivity using serum samples was 100%. Using the 4 seroconversion panels, the OraQuick HCV test showed results comparable to those of the laboratory-based assays; its analytical sensitivity was higher than that of the other rapid test kits. There was no cross-reactivity with common interfering factors. CONCLUSIONS: The clinical performance of the OraQuick HCV Test is comparable to that of laboratory-based tests with both serum and oral fluid. This supports the supplementary use of rapid HCV testing using oral fluid in various medical and non-medical settings.
