Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

Background/Aims: Recent epidemiologic studies have shown a continued increase in colorectal cancer incidence among younger adults. Little is known about the factors that contribute to the development of young-onset colorectal neoplasia (CRN). Methods: A cross-sectional analysis was performed for individuals younger than 40 years who underwent colonoscopy in Seoul St. Mary’s Hospital and its affiliated health screening center. High-risk CRN was defined as adenoma or sessile serrated lesion ≥ 10 mm, with three or more adenomas, villous histology, high grade dysplasia, or carcinoma. Results: Of these 13,621 included participants, 2,023 (14.9%) had one and more CRN. Young patients with CRN tended to be elderly, male, obese, smoker, having a habit of drinking, and having comorbidities such as hypertension, dyslipidemia, diabetes, and chronic kidney disease. In a multivariate analysis adjusted for age, sex, obesity, smoking status, and alcohol intake, old age (odds ratio [OR], 1.086; 95% confidence interval [CI], 1.054 to 1.119), male sex (OR, 1.748; 95% CI, 1.247 to 2.451), obesity (OR, 1.439; 95% CI, 1.133 to 1.828), and smoking (OR, 1.654; 95% CI, 1.287 to 2.127) were independent risk factors for overall CRN. Obesity and smoking as two modifiable factors increased the risk for high-risk CRN even more than for overall CRN (OR, 1.734; 95% CI, 1.168 to 2.575 and OR, 1.797; 95% CI, 1.172 to 2.753, respectively). Conclusions: Obesity and smoking were modifiable risk factors for CRN in young adults. They increased the risk for highrisk CRN even more than for overall CRN. A colonoscopy might be beneficial for young individuals with these factors.

Background and Objectives: Stem cells are a valuable resource for treatment of many disease, but limited access to stem cells in some organs such as brain restricts their utility. Many approaches have been attempted to restore the function following brain stem injury (BSI) and spinal cord injury (SCI). The use of the human umbilical cord blood cells (hUCB) - a rich source of nonembryonic or adult stem cells - has recently been reported to ameliorate the behavioral consequences of stroke. Mateiials and Methods: Forty rats were divided into 8 groups: (1) SCI l+hUCB (infused 1 day post injury); (2) SCI 2+hUCB (infused 2 days post injury); (3) SCI 3+hUCB (infused 3 days post injury); (4) SCI 4+hUCB (infused 4 days post injury); (5) SCI 5+hUCB (mfusedt 5 days post injury); (6) SCI 6+hUCB (infused 6 days post injury); (7) LO+hUCB (laminectomy+hUCB); and (8) LO (laminectomy only). SCI was produced by compressing the spinal cord for one minute with an aneurysm clip calibrated to a closing pressure of 50 g. We report here that immunhistotochemical identification of fluorescent hUCB positive cells in the brain stem after compressed spinal cord injury using mouse anti-human mitochondria monoclonal antibody (MAB1273). Results: All SCI+hUCB (1-8) groups contained fluorescent hUCB positive cells in the all area of the brain stem. But especially a large number of fluorescent hUCB positive cells were observed in the whole area of the brain stem of the experimental 5 (SCI 5+hUCB) and 6 (SCI 6+hUCB)groups. No hUCB positive cells were found in the brain stem of group with non-injured spinal cord of these animals and group with laminectomy only. Conclusion: These results suggest that hUCB are potentially useful as a vector for treating a variety of the central nervous system disorders, and we are sure that continuous of stem cell study will give an best opportunity to treat the uncurable disorders in the future.

간질성 신염은 신장의 간질을 선택적으로 침범하는 염증성 질환으로 여러가지 원인에 의해 유발되며, 이 중 약물에 의한 경우는 각종 항생제, 비스테로이드성 진통제, 항경련제, 이뇨제, 면역억제제등에 의한 증례들이 보고되고 있다. 현재 각종 질환-특히 만성질환-의 치료에서 한약이 차지하는 비중이 적지 않으나, 그 각각의 성분들이 유발할 수 있는 부작용들에 대한 연구는 거의 없는 실정이다. 저자들은 관절염 치료를 위해 중국산 한약을 복용한 후 복통, 피로감 및 육안적 혈뇨를 주소로 내원한 두 환자에서, 단백뇨와 신기능 장애를 보여 시행한 신조직 생검상 급성 간질성 신염에 합당한 병리학적 소견을 보이고, 한약 복용 중지 후 급속한 회복을 보여, 한약에 의해 유발된 것으로 사료되는 급성 간질성 신염 2예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Acute interstitial nephritis is a disease characterized by renal interstitial inflammatory cell infiltration and acute renal functional deterioration. This is caused mainly by antibiotics, NSAID and diuretics such as thiazide, but cases induced by herb medication are rare. We experienced two cases of acute interstitial nephritis after treatment with herb medication. One 71-year-old female patient and the other 60-year-old female were admitted to the hospital because of general weakness and gross hematuria. Microscopic hematuria, pyuria, and proteinuria were presented. After definitive diagnosis with a renal biopsy, we noted rapid recovery of renal function by drug withdrawal and steroid therapy. We report these cases with a review of the referenced literatures. Key Words : Herb medication, Acute Interstitial nephritis.

Identification of a sensitive urinary biomarker, selenium-binding protein 1, for early detection of acute kidney injury

Kim, Kyeong Seok,Yang, Hun Yong,Song, Hosup,Kang, Ye Rim,Kwon, JiHoon,An, JiHye,Son, Ji Yeon,Kwack, Seung Jun,Kim, Young-Mi,Bae, Ok-Nam,Ahn, Mee-Young,Lee, Jaewon,Yoon, Sungpil,Lee, Byung μ,Kim, Hyung TAYLOR & FRANCIS 2017 Journal of Toxicology and Environmental Health Vol.80 No.9

<P>Acute kidney injury (AKI) is associated with increased mortality rate in patients but clinically available biomarkers for disease detection are currently not available. Recently, a new biomarker, selenium-binding protein 1 (SBP1), was identified for detection of nephrotoxicity using proteomic analysis. The aim of this study was to assess the sensitivity of urinary SBP1 levels as an early detection of AKI using animal models such as cisplatin or ischemia/reperfusion (I/R). Sprague-Dawley rats were injected with cisplatin (6 mg/kg, once i.p.) and sacrificed at 1, 3, or 5 days after treatment. Ischemia was achieved by bilaterally occluding both kidneys with a microvascular clamp for 45 min and verified visually by a change in tissue color. After post-reperfusion, urine samples were collected at 9, 24, and 48 hr intervals. Urinary excretion of protein-based biomarkers was measured by Western blot analysis. In cisplatin-treated rats, mild histopathologic alterations were noted at day 1 which became severe at day 3. Blood urea nitrogen (BUN) and serum creatinine (SCr) levels were significantly increased at day 3. Levels of urinary excretion of SBP1, neutrophil gelatinase-associated lipocalin (NGAL), and a tissue inhibitor of metalloproteinase-1 (TIMP-1) were markedly elevated at day 3 and 5 following drug treatment. In the vehicle-treated I/R group, serum levels of BUN and SCr and AST activity were significantly increased compared to sham. Urinary excretion of SBP1 and NGAL rose markedly following I/R. The urinary levels of SBP1, NGAL, TIMP-1, and KIM-1 proteins excreted by AKI patients and normal subjects were compared. Among these proteins, a marked rise in SBP1 was observed in urine of patients with AKI compared to normal subjects. Based upon receiver-operator curves (ROC), SBP1 displayed a higher area under the curve (AUC) scores than levels of SCr, BUN, total protein, and glucose. In particular, SBP1 protein was readily detected in small amounts of urine without purification. Data thus indicate that urinary excretion of SBP1 may be useful as a reliable biomarker for early diagnosis of AKI in patients.</P>

Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

On non-moraic geminates

Young-Seok Kim 한국음운론학회 2002 음성·음운·형태론 연구 Vol.8 No.2

Kim, Young-Seok 2002. On Non-moraic Geminates. Studies in Phonetics, Phonology and Morphology 8.2. 187-200. In Moraic Theory, it is generally assumed that geminates are lexically specified for a mora, so that a CVC syllable should always count as heavy if the coda consonant is part of an underlying geminate, even in languages like Korean where a CVC syllable invariably counts as light otherwise. Based on I-gemination and other geminates derived by total assimilation, we show that this assumption is simply not tenable. The mora is a unit of phonological weight, not of segment length. In this paper we explore ways to represent non-moraic geminates, and propose a return to the skeletal theory minimally supplemented with the Moraic Projection. (Sogang University)

In this study, we compared backpropagation network(BPNN) with probabilistic neural network(PNN) as the classification algorithm of welding flaws. For this purpose variables are appied the same to two algorithm. Here, feature variable is composed of time signal itself and frequency signal itself. Those are ultrasonic signals reflected on welding flaws. Through this process, we comfirmed advantages/disadvantages of two algorithms, identified application methods of two algorithms to classification methods of welding flaws. These advantages/disadvantages and application methods are based on theoretical backgrounds.
