Background: Urinary kidney injury molecule-1 (KIM-1) is an early and sensitivebiomarker of acute kidney injury, but it is unclear if it is a biomarker of chronicglomerulonephritis. We evaluated whether urinary KIM-1 levels in patients withimmunoglobulin A (IgA) nephropathy can be a marker to reflect clinicopathologicalseverity and predict the prognosis. Methods: We measured urinary KIM-1 levels in 40 patients (15 males; mean age36.6712.9 years) with IgA nephropathy and 10 healthy people (5 males; mean age37.379.6 years) as controls. The correlation of urinary KIM-1 levels with patients’clinical parameters, histological grades, and follow-up data were analyzed using themodified H. S. Lee grading system and tubulointerstitial change scores. Results: Urinary KIM-1 levels were higher in patients with IgA nephropathy thanhealthy controls (P¼0.001). Univariate and multivariate regression analyses showedthat urinary KIM-1 levels had a direct correlation with H. S. Lee grade andtubulointerstitial inflammation (P¼0.004 and P¼0.011, respectively). Conclusion: In patients with IgA nephropathy, urinary KIM-1 has a significantcorrelation with histopathologic severity.

No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

Purpose: The consequences of precipitously rising allergic skin inflammation rates worldwide have accelerated the risk of atopic dermatitis (AD). Natural product-based agents with good efficacy and low risk of side effects offer promising prevention and treatment strategies for inflammation-related diseases. We have already reported that Platycodon grandiflorum root-derived saponins (Changkil saponins, CKS) have many pharmacological effects, including anti-inflammatory and anti-allergic effects, but its influence on AD remains unclear. Therefore, we evaluated the inhibitory effect of CKS, mainly platycodin D, on AD-like skin symptoms in mice and the possible mechanisms in cells. Methods: Mice were sensitized and challenged with 2,4-dinitrochlorobenzene (DNCB). Four weeks after challenge, mice were treated with oral administration of CKS for 4 weeks. In addition, cells were used to evaluate the effect of CKS, mainly platycodin D, on the TARC expression regulated mechanism. Results: CKS attenuated DNCB-induced dermatitis severity, serum levels of IgE and TARC, and mRNA expression of TARC, TNF-α, IFN-γ, IL-4, IL-5, and IL-13 in mice. Histopathological examination showed reduced thickness of the epidermis/dermis and dermal infiltration of inflammatory cells and mast cells in the ears. Moreover, CKS and platycodin D inhibited TNF-α/IFN-γ-induced TARC expression through the suppression of NF-κB and STAT1 and induction of Nrf2/ARE-mediated hemeoxygenase-1 (HO-1) expression in cells. Conclusion: We suggest that CKS and platycodin D inhibited the development of AD-like skin symptoms by regulating cytokine mediators and may be an effective alternative therapy for AD-like skin symptoms.ⓒ2014 Elsevler Gmbh.

Non-Hodgkin's 림프종의 약 40%는 결절외(extranodal) 림프종으로 대개 위장관에서 발생하며 이들 중 점막 연관 림프조직(mucosa-associated lymphoid tissue: MALT)에서 기원한 림프종은 MALT 림프종으로 분류된다. 위 외의 부위에서 원발성으로 발생하는 MALT 림프종은 매우 드물지만 실제 거의 모든 신체 장기에 발생하는 것으로 알려져 있는데, 가장 흔한 부위인 위 외에도 폐, 갑상선, 침샘, 눈물샘에 발생하고, 드물게 안구, 유방, 방광, 신장, 흉선 등에도 보고된 바 있다. MALT 림프종은 오랜 기간동안 원격 전이하지 않고 국소 병변으로 남아 있는 특징이 있어 치료 방향 또한 국소 병변의 치료에 집중되며, 예후도 림프절 기원의 림프종에 비해 양호한 것으로 알려져 있다. 본 저자 등은 자궁 내막에 원발성으로 발생한 MALT 림프종 1예를 경험하였기에 문헌 고찰과 함께 이를 보고하고자 한다. Mucosa associated lymphoid tissue (MALT) lymphoma can rarely develop primarily in extranodal sites other than stomach which is the most common site for it. Other rare primary sites are small intestine, colorectum, esophagus, lung, thyroid, salivary gland, lacrymal gland, breast and skin. MALT lymphoma represents a distinct clinicopathologic features: it is usually localized to their original site for a long time and shows much more favorable prognosis than lymphoma at other site, but some MALT lymphoma can arise simultaneously or successively in different organ or give rise to another MALT lymphoma of other organ and can be multifocally disseminated or recurred. We report a very rare case of high grade B-cell lymphoma of mucosa associated lymphoid tissue (MALT) of the uterine endometrium, which was confirmed by immunohistochemical assay.

The button mushroom (Agaricus bisporus) is one of the most widely cultivated important edible mushroom species. In the breeding of new button mushroom, ‘Seolgang’ was developed by crossing two monokaryons ‘CM020913-27’ and ‘SSU423-31’. Because of the secondarily homothallism, only a small percentage of the basidia produce 3 or 4 spores, which are mostly haploid (n) and do not fruit. Single spore cultures derived from these types of spores produce a vegetative mycelium that also contain a variable number of genetically identical nuclei per cell called monokaryon. The lack of clamp connections between monokaryon and dikaryon required a series of mycelial culture and fruiting test. After crossing, hybrids were cultivated on a small scale and on a commercial scale at a farm. For this, the spawn was made by a commercial spawn producer and the spawned compost by a commercial compost producer. Mycelial growth of ‘Seolgang’ on CDA was better at 20℃ and 25℃ when it was compared with that of ‘505 Ho’. The mature cap shape of new strain ‘Seolgang’ is oblate spheroid and the immature cap shape is round to oblate spheroid. The cap diameter was 41.2 mm on average. In comparison with white strain ‘505 Ho’, the strain had a yield that was 9% higher. It produced fruiting bodies which had a higher weight on average per fruiting body and were 19% firmer with a good shelf life. Days of fruiting body were 3-4 days later than those of ‘505 Ho’. The physical characteristics such as elasticity, chewiness, adhesiveness were better than that of ‘505 Ho’. Genetic analysis of the new strain ‘Seolgang’ showed different profiles compared to ‘505 Ho’, CM02913-27, SSU413-31, when RAPD primers A02 and O04 were used.

For evaluating the lumbar disc space, the fact that the postmyelography computed tomography was more accurate than computed tomography or myelography was well know. But the technical difficulty is limitation of gantry angle. The prone position scanning may help to lessen this trouble. A prospective computed tomographic scanning was performed in both the prone and supine position on 43 patients, who had low back pain. The angle between the vertebral end plate and vertical line was measured in both position at ??, ?? and ?? interspaces. The adavantages of prone scanning in spinal aligment was noted at L5-S1 disc space(79.1%) and also more desirable if computed tomography was performed with metrizamide. With above advantages, the evaluation of bulging annulus was become more easier.

Product liability (PL) law has been in force since July 2002 in Korea. PL burdens manufacturer with additiuonal cost and this PL cost depends on product reliability. Product reliability is influenced by the decisions made during the design and manufacturing of the product. In this paper, PL cost considering injury intensity, customer claim and product reliability is quantified and a reliability design model is presented. The optimal reliability and development period to minimize total cost which includes manufacturing cost, PL cost and product development cost are determined. Numerical experiments are illustrated to evaluate the model and sensitivity analysis is performed.
