  • Loss of pancreatic β-cells by oxidative stress or cytokines is associated with diabetes mellitus (DM). DJ-1 is known to as a multifunctional protein, which plays an important role in cell survival. We prepared cell permeable wild type (WT) and mutant type (M26I) Tat-DJ-1 proteins to investigate the effects of DJ-1 against combined cytokines (IL-1β, IFN-γ and TNF-α)-induced RINm5F cell death. Both Tat-DJ-1 proteins were transduced into RINm5F cells. WT Tat-DJ-1 proteins significantly protected against cell death from cytokines by reducing intracellular toxicities. Also, WT Tat-DJ-1 proteins markedly regulated cytokines-induced pro- and anti-apoptosis proteins. However, M26I Tat-DJ-1 protein showed relatively low protective effects, as compared to WT Tat-DJ-1 protein. Our experiments demonstrated that WT Tat-DJ-1 protein protects against cytokine-induced RINm5F cell death by suppressing intracellular toxicities and regulating apoptosisrelated protein expression. Thus, WT Tat-DJ-1 protein could potentially serve as a therapeutic agent for DM and cytokine related diseases.

  • In this study, the immunological effect of a traditional Korea herbal acupuncture, that has been widely used for the treatment of various immunological disorders including inflammation in Korea, was examined in vitro and in vivo. In our previous study demonstrated that BV increased the expression of IFN-γ mRNA, that plays pivotal role in T cell response. This study was designated to evaluate the effect of BV on helper T cell development by monitoring Th1/Th2 specific cytokine secretion patterns in artificially induced Th1/Th2 polarized condition and in vivo. The results demonstrated that BV didn't have mitogenic effects on the unstimulated CD4+ T cell, but increased the CD4+ T cell proliferation upon activation with anti-CD3/CD28 antibody. The Th1 cells were over-populated dramatically in Th1 driven condition with BV treatment, while the Th2 cells were increased slightly in Th2 skewed condition. Furthermore, under Th1-skewed conditions, the level of IFN-γ was considerably increased with BV treatment. Besides, the expression of T-bet, a transcription factor that plays pivotal role in Th1 lineage programming, was increased with BV treatment. The expressions of IFN-γ and T-bet were also significantly increased in vivo. The results that Th1 specific cytokine secretion were considerably increased and Th2 specific cytokine secretion were not significantly changed in vitro and in vivo indicated that BV enhances Th1 lineage development, Therefore, these results suggest that BV might be desirable agent for correction of Th1 dominant pathological disorders.

  • Porcine circovirus type 2 (PCV2) is a single-stranded circular DNA virus associated with Postweaning multisystemic wasting syndrome (PMWS), which is considered to be an important infectious swine viral disease. PCV2 capsid protein encoded by ORF2 is a structural protein and expected as the high immunogenicity protein. In this study, we generated recombinant baculovirus containing ORF2 of PCV2 and analyzed the optimal conditions for the production of capsid protein in insect cell. Production and status of recombinant capsid protein in insect cell were confirmed by SDS-PAGE and Western blot analysis using His tag antibody and anti-PCV2 serum. The yield of recombinant capsid protein was high like as shown visible on SDS-PAGE. Optimal multiplicity of infection (MOI) and infection time of recombinant virus were determined as 5 MOI and 4 days, respectively. ORF2 is known to have N-linked glycosylation site, but we couldn't detect the glycosylation of recombinant protein in insect cells.

  • The black seed coat of soybeans contain anthocyanins which promote health. However, mature soybean seeds contain anti-nutritional factors like lipoxygenase, lectin and Kunitz Trypsin Inhibitor (KTI) proteins. Furthermore, these seeds can be used only after the genetic elimination of these proteins. Therefore, the objective of this study was to develop novel soybean genotypes with black seed coat and triple recessive alleles (lx1lx1lx2lx2lx3lx3, titilele) for lipoxygenase, lectin, and KTI proteins. From a cross of parent1 (lx1lx2lx3/lx1lx2lx3, ti/ti, Le/Le) and parent2 (lx1lx2lx3/lx1lx2lx3, Ti/Ti, le/le), 132 F2 seeds were obtained. A 3:1 segregation ratio was observed during F2 seed generation for the inheritance of lectin and KTI proteins. Between a cross of the Le and Ti genes, the observed independent inheritance ratio in the F2 seed generation was 9: 3 : 3 : 1 (69 Le_Ti_: 32 leleTi_: 22 Le_titi: 9 leletiti) (χ2=2.87, P=0.5 - 0.1). From nine F2 seeds with triple recessive alleles (lx1lx1lx2lx2lx3lx3, titilele genotype), one novel strain posessing black seed coat, and free of lipoxygenase, lectin and KTI proteins, was selected. The seed coat color of the new strain was black and the cotyledon color of the mature seed was green. The weight of 100 seeds belonging to the new strain was 35.4 g. This black soybean strain with lx1lx1lx2lx2lx3lx3, titilele genotype is a novel strain free of lipoxygenase, lectin, and KTI proteins.

  • Objectives: We estimated the asthma-related health care utilization and costs in Korea from the insurer's and societal perspective. Methods: We extracted the insurance claims records from the Korea National Health Insurance claims database for determining the health care services provided to patients with asthma in 2003. Patients were defined as having asthma if they had ${\geq}$2 medical claims with diagnosis of asthma and they had been prescribed anti-asthma medicines, Annual claims records were aggeregated for each patient to produce patient-specific information on the total utilization and costs. The total asthma-related cost was the sum of the direct healthcare costs, the transportation costs for visits to health care providers and the patient's or caregivers' costs for the time spent on hospital or outpatient visits. Results: A total of 699,603people were identified as asthma patients, yielding an asthma prevalence of 1.47%. Each asthma patient had 7.56 outpatient visits, 0.01 ED visits and 0.02 admissions per year to treat asthma. The per-capita insurance-covered costs increased with age, from 128,276 Won for children aged 1 to 14 years to 270,729 Won for those aged 75 or older. The total cost in the nation varied from 121,865 million to 174,949 million Won depending on the perspectives. From a societal perspective, direct health care costs accounted for 84.9%, transportation costs for 15.1 % and time costs for 9.2% of the total costs. Conclusions: Hospitalizations and ED visits represented only a small portion of the asthma-related costs. Most of the societal burden was attributed to direct medical expenditures, with outpatient visits and medications emerging as the single largest cost components.

  • The KFDA (Korea Food & Drug Administration) has performed a collaborative toxico-genomics project since 2003. Its aim is to construct a toxicologenomic database of 12 hepatotoxic compounds from mice livers. Phenylbutazone which is non-steroidal anti-inflammatory drug was assigned. It was administered at low (0.0238 mg/kg) and at high (0.238 mg/kg) dose (5 mice per group) orally to the postnatal 6 weeks ICR mice, then the serum and liver were collected at the indicated time (6, 24 and 72 h) after administration. Serum biochemical markers for liver toxicity were measured and histopathologic studies also were carried out. The gene expression profiling was carried out by using Applied Biosystems 1700 Full Genome Expression Mouse. The 2-way ANOVA was used to find genes that reflected phenylbutazone-induced acute toxicity or dose-dependant changes. By self-organization maps (SOM), we identified groups with unique gene expression patterns, some of them are supposed to be related to phenylbutazone induced toxicity, including lipid metabolism abnormality, oxidative stress, cell death and cytoskeleton destruction.

  • To develope the novel anti-allergic drug, many sophoricoside derivatives were synthesized. Among these derivatives, JSH-II-3, JSH-Ⅵ-3, JSH-Ⅶ-3, and JSH-Ⅷ-3 were selected and subjected to high throughput toxicity screening (HTTS) because they revealed strong IL-5 inhibitory activity and limitation of quantity. Mouse lymphoma thymidine kinase (tk$\^$+/-/) gene assay (MOLY) and single cell gel electrophoresis (Comet) assay in mammalian cells were used as HTTS tool in our laboratory. In MOLY assay, JSH-Ⅶ-3 at 50 ∼ 6 $\mu\textrm{g}$/ml concentrations was not shown significant mutagenic effect in the absence and presence of S-9 metabolic activation system. However, the concentration of ISH-II-3, 38 $\mu\textrm{g}$/ml, induced increased mutation frequency (MF) in the presence of S-9 metabolic activation system. Also in comet assay, DNA damage was not observed in JSH-Ⅵ-3 and JSH-Ⅶ-3, wherase concentration of 32.8 $\mu\textrm{g}$/ml in JSH-II-3 and 13.9 $\mu\textrm{g}$/ml in JSH-Ⅶ-3 were induced DNA damage in the absence of S-9 metabolic activation system. Therefore, we suggest that JSH-Ⅵ-3 and JSH-Ⅶ-3 have no genotoxic effects but JSH-II-3 and JSH-Ⅷ-3 induce some mutagenicity and DNA strand breaks in mouse lymphoma cell line used this study.

  • This study is to enhance drug penetration via skin and investigate anti-inflammation effect following adoption of ultrasound. For this goal gel containing triamcinolone was prepared and the skin penetration rate and the change effects of blood plasma ingredients and serum enzyme were investigated. Using Franz type diffusion cell and the skin of hairless mouse, the permeation enhancing effect of ultrasound was tested. After the injury by direct trauma, the blood test was performed by measuring WBC, lymphocyte, and neutrophyl, and by analyzing CPK and LDH. The ultrasound transducer whose technical specification is geometric area(GA) $1.4\;cm^2$, effective radiation area(ERA) $0.8\;cm^2$, and beam non-uniformity ratio(BNR) 6.0 max was used. The influence of frequency having an effect on skin permeation rate was higher in the case of using 1MHz and continuous treatment. The temperature of receptor phase was not influenced in skin permeation by phonophoresis. Skin permeation increase attended by intensity of ultrasound, the permeation of triamcinolone was accelerated at $2.5\;w/cm^2\;than\;1.0\;w/cm^2$. Following muscle injury phonophoretic group the number of WBC, neutrophil and lympholyte were decreased significantly as compared with both control group and ultrasound group. The result of variation of serum CPK and LDH activity conformed to the phonophoretic effect as same pattern with the variation of WBC, neutrophil and lymphocyte.

  • BACKGROUND/OBJECTIVES: Inflammation is associated with various types of acute and chronic alcohol liver diseases. In this study, we examined whether umbelliferone (7-hydroxycoumarin, UF) ameliorates chronic alcohol-induced liver damage by modulating inflammatory response and the antioxidant system. METHODS: Rats were fed a Liber-Decarli liquid diet containing 5% alcohol with or without UF (0.05 g/L) for 8 weeks, while normal rats received an isocaloric carbohydrate liquid diet. RESULTS: Chronic alcohol intake significantly increased serum tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin 6 levels and decreased interleukin 10 level; however, UF supplementation reversed the cytokines related to liver damage. UF significantly suppressed hepatic lipopolysaccharide binding protein, toll-like receptor 4 (TLR4), nuclear factor kappa B, and TNF-${\alpha}$ gene expression increases in response to chronic alcohol intake. Masson's trichrome staining revealed that UF improved mild hepatic fibrosis caused by alcohol, and UF also significantly increased the mRNA expressions and activities of superoxide dismutase and catalase in liver, and thus, decreased lipid peroxide and mitochondrial hydrogen peroxide levels. CONCLUSIONS: The findings of this study indicate that UF protects against alcohol-induced liver damage by inhibiting the TLR4 signaling pathway and activating the antioxidant system.
