Korean oriental medicine prescription is widely used for the treatment of gouty diseases. In the present study, we investigated anti-inflammatory effects of modified Korean herbal formulation, mixed extract of medicinal herbs(MEMH), and its modulatory effects on inflammatory mediators associated with gouty arthritis. Both in vitro and in vivo studies were carried out to assess the anti-inflammatory efficacy of MEMH on monosodium urate(MSU) crystals-induced gouty inflammation. MSU crystals stimulated human chondrosarcoma cell line, SW1353, and human primary chondrocytes were treated with MEMH in vitro. The expression levels of pro-inflammatory mediators and metalloproteases were analyzed. The effect of MEMH on NFκB signaling pathway in SW1353 cells was examined. Effect of MEMH on the mR NA expression level of pro-inflammatory mediators and chemotactic factor from human monocytic cell line, THP-1, was also analyzed. The probable role of MEMH in the differentiation process of osteoblast like cells, SaO S-2, after MSU treatment was also observed. To investigate the effects of MEMH in vivo, MSU crystals-induced ankle arthritic model was established. Histopathological changes in affected joints and plasma levels of pro-inflammatory mediators(IL-1β and TNFα) were recorded. MEMH inhibited NFκB signaling pathway and COX-2 protein expression in chondrocytes. MSU-induced mR NA expressions of pro-inflammatory mediators and chemotactic cytokines were suppressed by MEMH. In MSU crystals-induced ankle arthritic mouse model, administration of MEMH relieved inflammatory symptoms and decreased the plasma levels of IL-1β and TNFα. The results indicated that MEMH can effectively inhibit the expression of inflammatory mediators in gouty arthritis, demonstrating its potential for treating gouty arthritis.

OBJECTIVE: To quantitatively evaluate the therapeutic effects of Red Liriope platyphylla(RLP) on atopic dermatitis(AD), alterations in the luciferase(Luc) signal and general phenotype biomarkers were compared in phthalic anhydride(PA) treated Interleukin-4(IL-4)/Luc/Consensus non-coding sequence-1(CNS-1) transgenic(Tg) mice following treatment with aqueous extract of RLP(AEt RLP) for4 ***: Alterations in AD phenotypes were measured in IL-4/Luc/CNS-1 Tg mice following treatment with AEt RLP using inflammation parameter analysis, bioluminescence imaging analysis, histological analysis, reverse transcription-polymerase chain reaction, enzyme linked immunosorbent assay and Western blot ***: RLP contained high concentrations of total phenolic compounds, total flavonoid compounds and 5-HNE related to AD therapy. The Luc signal was only detected in the abdominal region and the submandibular lymph node(SL), mesenteric lymph node(ML), thymus and pancreas of the PA treated group. This signal was significantly decreased by 28%-73% throughout the body and in the four organs in PA + AEt RLP treated group. Furthermore, the lymph node weight, immunoglobulin E concentration and dermal thickness were decreased by 37%-67% in the PA + AEt RLP treated ***: Our findings suggest that the therapeutic effect of AEt RLP on PA induced AD could be successfully quantified by comparison of Luc signals and AD phenotype markers in IL-4/Luc/CNS-1Tg mice, and that the Luc signal was as sensitive as the general AD phenotypes, enabling detection of effects without euthanasia.

AIM： To investigate the role of O-GIcNAcylation of nuclear factor-kappa B （NF-KB） in retinal ganglion cell （RGC） death and analysedthe effect of Aralia elata （AE） on neurodegen- eration in diabetic mice. METHODS： C57BL/6mice with streptozotocin-induced diabetes were fed daily with AE extract or control （CTL） diet at the onset of diabetes mellitus （DM）. Two months af- tar injection of streptozotocin or saline, the degree of cell death and the expression of O-GIcNAc transferase （OGT）, N-acetyl-b-D-glucosaminidase （OGA）, O-GIcNAcylated pro- teins, and O-GIcNAcylation of NF-KB were examined. RESULTS： AE did not affect the metabolic status of diabetic mice. The decrease in the inner retinal thickness （P〈0.001 vs CTL, P〈0.01 vs DM） and increases in RGCs with terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling （P〈0.001 vs CTL, P〈0.0001 vs DM）, glial activation, and active caspase-3 （P〈0.0001 vs CTL, P〈0.0001 vs DM） were blocked in diabetic retinas of AE extract-fed mice. Expression levels of protein O-GIcNAcylation and OGT were increased in diabetic retinas （P〈0.0001 vs CTL）, and the level of O-GIcNAcylation of the NF-KB p65 subunit was higher in diabetic retinas than in controls （P〈0.0001 vs CTL）. AE extract downregulated O-GIcNAcylation of NF-KB and prevented neurodegeneration induced by hyperglycemia （P〈0.0001 vs DM）. CONCLUSION： O-GIcNAcylation of NF-KB is concerned in neuronal degeneration and that AE prevents diabetes-in- duced RGC apoptosis via downregulation of NF-KB O-GI- cNAcylation. Hence, O-GIcNAcylation may be a new object for the treatment of DR, and AE may have therapeutic pos- sibility to prevent diabetes-induced neurodegeneration.

Background Although some studies measured the burden of caregivers and the factors that influenced their feelings of burden, few studies have measured the quality of life （QOL） for primary caregivers of patients with muscular dystrophy （MD）. We assessed the QOL for primary caregivers of patients with MD in South Korea and identified factors associated with caregivers＇ QOL. Methods Ninety dyads of patients with MD and their primary caregivers were enrolled in this study. The QOL of caregivers of patients with MD was assessed subjectively using the World Health Organization Quality of Life Assessment, Life Brief Form. Caregivers＇ emotional status was assessed using the Beck Depression Inventory （BDI） and family function level was evaluated using the Family APGAR scale. Patients reported their emotional status using the BDI or the Children＇s Depression Inventory. The functional levels of patients were evaluated by the modified Barthel Index. Results Caregivers＇ QOL was statistically associated with family income, family function, emotional status of patients, level of education, and emotional status of caregivers （P 〈0.05）. Caregivers who were employed had a significantly higher QOL than those who were not （P 〈0.05）. In multiple regression analyses, emotional and employment status of caregivers was strongly associated with caregivers＇ QOL. Conclusion Rehabilitation teams should consider not only the physical factors of patients but also the psychological and demographic factors of primary caregivers of patients with MD.

Chinese Science Bulletin 2010年第1期55卷 94-98页

作者： LEE jun-hee PARK Su-A PARK KoEun KIM Jae-Hyun KIM Kyung-Shik LEE Jihye Kim WanDoo Bio-Mechatronics Team Division of Nano-Machinery Korea Institute of Machinery and Materials (KIMM) Nano-Mechanics Team Division of Nano-Machinery Korea Institute of Machinery and Materials (KIMM) Nano-Mechatronics Team Division of Nano-Machinery Korea Institute of Machinery and Materials (KIMM)

In this paper, we design and fabricate a 3D scaffold using rapid prototyping (RP) technology for tissue engineering. The scaffold should have a three-dimensional interconnected pore network. We fabricate a polycaprolactone (PCL) scaffold with interconnecting pores and uniform porosity for cell ingrowth using a 3D plotting system. In order to keep the three dimensional shape under mechanical loading while implanted, we design an oscillating nozzle system to increase elastic modulus and yield strength of PCL strand. We characterize the influence of pore geometry, compressive modulus of the scaffold, elastic modulus and yield strength of the strand using SEM, dynamical mechanical analysis (DMA) and Nano-UTM. Finally the cell responses on scaffolds are observed.

LTD Seoul 132-703 Korea

The purpose of this study was to determine the relationship between insulin resistance, obesity and serum prostate-specific antigen （PSA） levels in healthy men with serum PSA level below 4 ng mL-1. The men included in the study cohort were 11 827 healthy male employees of the Korea Hydro and Nuclear Power Co., LTD who had undergone medical checkups including fasting glucose, fasting insulin and serum PSA between January 2003 and December 2008. Insulin resistance was calculated by homeostasis model assessment （HOMA [fasting glucose × fasting insulin]/22.5） and quantitative insulin sensitivity check index （QUICK/; 1/[log （fasting insulin）＋ log （fasting glucose）]）. Age-adjusted body mass index （BMI） was significantly increased according to increasing quartile of insulin resistance as determined by HOMA and QUICKI, respectively, in analysis of variance （ANOVA） test and Duncan＇s multiple comparison test （P 〈 0.001）, but age-adjusted serum PSA concentration was significantly decreased according to increasing quartile of insulin resistance as determined by HOMA and QUICK/（P 〈 0.001）. Age, BMI, insulin resistance by HOMA or QUICK/were significantly independent variables to serum PSA level in a multivariate linear regression analysis （P 〈 0.001）. Insulin resistance was a significant independent variable to serum PSA level along with BMI. Insulin resistance and BMI were negatively correlated with serum PSA level in healthy men. Insulin resistance was positively correlated with BMI.
