The fruit of Terminalia chebula Retzius has been used as a panacea in India and Southeast Asia but its biological activities have not been fully elucidated. Here we report anti-arthritic and analgesic effect of NDI10218, a standardized ethanol extract of Terminalia chebula, on collagen-induced arthritis and acetic acid-induced writhing model, respectively. Arthritis was induced in DBA/1J mice by immunizing bovine type II collagen and mice were treated with NDI10218 daily for 5 weeks after the onset of the disease. NDI10218 reduced the arthritis index and blocked the synovial hyperplasia in a dose-dependent manner. The serum levels of pro-inflammatory cytokines TNF-${\alpha}$, IL-6, and IL-$1{\beta}$ were significantly reduced in mice treated with NDI10218. Production of the inflammatory IL-17, but not immunosuppressive IL-10, was also inhibited in splenocytes isolated from NDI10218-treated arthritis mice. Administration of NDI10218 markedly decreased the number of T cell subpopulations in the regional lymph nodes of the arthritis mice. Finally, NDI10218 reduced the number of abdominal contractions in acetic acid-induced writhing model, suggesting an analgesic effect of this extract. Taken together, these results suggest that NDI10218 can be a new therapeutic candidate for the treatment of rheumatoid arthritis.

Objective : Airway inflammation is now regarded as a defining feature of asthma. The importance of eosinophits in the airway inflammation of asthma patients is widely recognized, and eosinophils mobilization in the respiratory epithelium is activated by chemoattractants and cytokines. This study was designed to examine the extent of the ability of Moutan Cortex Radicis to inhibit eosinophil chemotaxis of pulmonary epithelium after allergic stimulation. Material and Methods : Water extracts of Moutan Cortex Radicis and pulmonary epithelial cell lines A549(human type II-like epithelial cells) and human eosinophils were used. Cytotoxic effects of Moutan Cortex Radicis were estimated via MTS assay, and the effects of Moutan Cortex Radicis on chemokines from prestimulated A549 cells were estimated by sandwich ELISA and RT-PCR. Chemotaxis assay on prestimulated eosinophils treated with Moutan Cortex Radicis. was conducted Result : In this study we demonstrated that $TNF-{\alpha}$ and IL-4, $IL-1{\beta}$ induced the accumulation of chemokines' mRNA in the pulmonary epithelial cell lines A549 in a dose-dependent manner. Chemokines of eotaxin, ICAM-1, YCAM-1, IL-8, IL-16 were inhibited by Moutan Cortex Radicis in a dose dependent manner, but RANTES showed no inhibition due to Moutan Cortex Radicis. Eosinophil migration was inhibited at high concentrations of Moutan Cortex Radicis. Conculusion : These findings are indicative of supression of chemokines accomplished by Moutan Cortex Radicis treatment, demonstrating the potential therapeutic value of Moutan Cortex Radicis for treating diseases such as asthma.

Pregnancy is a unique event in which a fetus develops in the uterus despite being genetically and immunologically different from the mother, and the underlying mechanisms remain poorly understood. To analyze the differential gene expression profiles in nonpregnant and 7 days post coitus (dpc) pregnant uterus of mice, we performed a global proteomic study by 2-D gel electrophoresis (2-DE) and MALDI-TOF-MS. The uterine proteins were separated using 2-DE, Approximately 1,000 spots were detected on staining with Coomassie brilliant blue. An image analysis using Melanie III (Swiss Institute for Bioinformatics) was performed to detect variations in protein spots between pregnant and nonpregnant uterus. Twenty-one spots were identified as differentially expressed proteins, of which 10 were up-regulated proteins such as alpha-fetoprotein, chloride intracellular channel 1, transgelin, heat-shock protein beta-1, and carbonic anhydrase II, while 11 were down-regulated proteins such as X-box binding protein, glutathione S-transferase omega 1, olfactory receptor Olfr204, and metalloproteinase-disintegrin domain containing protein TECADAM. Most of the identified proteins appeared to be related with catabolism, cell growth, metabolism, regulation, cell protection, protein repair, or protection. Our results uncovered key proteins of mouse uterus involved in pregnancy.

Objectives : This study was carried out to know the anti-osteroarthritic effects of Bangkibokryeong-tang(Fanjifuling-tang(BBT)) on the papain-induced osteoarthritis C57BL/10 mouse. Methods : Osteoarthritis was induced by injection of papain(6 ${\mu}l$) into knee joint of mouse. Osteoarthritic mice were divided into 4 groups(normal, control, joins(R), BBT). The injection did not fit the normal group. A week later, after the injection of papain, control group was taken normal saline 200 ${\mu}l$, positive control group was taken joins(R)(100 mg/kg), treated group was taken extract of Bangkibokryeong-tang(Fanjifuling-tang(BBT))(400 mg/kg). After then, we examined hepatotoxicity, nephrotoxicity, inflammation cytokines, expression of inflammation factor mRNA, hemotology, histology through the micro CT-arthrography, and etc. Results : 1. Hepatotoxicity and nephrotoxicity have not expressed. 2. The levels of IL-$1{\beta}$, TNF-${\alpha}$, IL-6, MCP-1, Thromboxane B2, Leukotriene B4, Prostaglandin E2 in serum were significantly decreased. 3. In hematology, the levels of neutrophils and monocytes were significantly decreased. 4. The expression of inflammation factor mRNA like TNF-${\alpha}$ and IL-6, COX-2, iNOS-II were significantly inhibited. 5. In micro CT-arthrography, cartilage volume was less decreased. 6. The degree of osteoarthritis induced damage of joint of BBT group is low in histopathologic observation(hematoxylin&eosin(H&E), Safranin-O). Conclusions : According to this study, BBT has effect of anti-osteoarthritis. Further clinical research for the cartilage protective effect is necessary.

We report the expression, purification, and characterization of L-asparaginase (AnsA) from Rhizobium etli. The enzyme was purified to homogeneity in a single-step procedure involving affinity chromatography, and the kinetic parameters $K_m$, $V_{max}$, and $k_{cat}$ for L-asparagine were determined. The enzymatic activity in the presence of a number of substrates and metal ions was investigated. The molecular mass of the enzyme was 47 kDa by SDS-PAGE. The enzyme showed a maximal activity at $50^{\circ}C$, but the optimal temperature of activity was $37^{\circ}C$. It also showed maximal and optimal activities at pH 9.0. The values of $K_m$, $V_{max}$, $k_{cat}$, and $k_{cat}/K_m$ were $8.9{\pm}0.967{\times}10^{-3}$ M, $128{\pm}2.8$ U/mg protein, $106{\pm}2s^{-1}$, and $1.2{\pm}0.105{\times}10^4M^{-1}s^{-1}$, respectively. The L-asparaginase activity was reduced in the presence of $Mn^{2+}$, $Zn^{2+}$, $Ca^{2+}$, and $Mg^{2+}$ metal ions for about 52% to 31%. In addition, we found that $NH_4{^+}$, L-Asp, D-Asn, and ${\beta}$-aspartyl-hydroxamate in the reaction buffer reduced the activity of the enzyme, whereas L-Gln did not modify its enzymatic activity. This is the first report on the expression and characterization of the L-asparaginase (AnsA) from R. etli. Phylogenetic analysis of asparaginases reveals an increasing group of known sequences of the Rhizobial-type asparaginase II family.

Objectives : The effects of water extract of deer antler herbal-acupunture solution(DHS), prepared from the pilose antler of Cervus korea TEMMINCK var. mantchuricus Swinhoe (Nokyong), a traditional immunosuppressive and immune-activating Korean herbal- acupuncture, on collagen-induced arthritis(CIA:RA model) in mice was studied. Destruction of cartilage and bone are hallmarks of human rheumatoid arthritis, and controlling these erosive processes is the most challenging objective in the treatment of RA. Methods : We investigated the tissue protective effects of deer antler treatment using established murine collagen-induced arthritis(CIA) as a model. Potential synergy of low dosages of anti-inflammatory glucocorticosteroids and deer antler was also evaluated. Results : Treatment of established murine CIA with deer antler herbal-acupunture solution(DHS) $(10-50{\mu}g/day)$ suppressed disease activity and protected against cartilage and bone destruction. Although $10-50{\mu}g/day$ DHS had only a moderate effect on the inflammatory component of the disease activity, it strongly reduced cartilage pathology, as determined by histological examination. Serum cartilage oligomeric matrix protein(COMP) levels were significantly reduced, confirming decreased cartilage involvement. Histological analysis showed that bone destruction was prevented. DHS administration increased serum IL-1Ra levels and reduced anticollagen type II antibody levels. Treatment with low-dose $DHS(1{\mu}g/day)$ was ineffective in suppressing disease score, serum COMP or joint destruction. Synergistic suppression of both arthritis oseverity and COMP levels was noted when low-dose DHS was combined with prednisolone(0.05mg/kg/day), however, which in itself was not effective. Conclusion : DHS was shown to have the inhibiting effects against $IL-1{\alpha}-$ and $IL-1{\beta}-stimulated$ bone resorption. These results indicated that the DAS is not only highly stable and applicable to clinical uses in bone resorption, but also it will be served as a potent anti-inflammatory and anti-arthritic agents for treatment of human RA.

Objectives & Methods : The purpose of this study is to observe the effects of Angelicae Radix Pharmacopuncture(AR-P) at Joksamni(ST36) on collagen II induced arthritis in DBA/1J mice. The authors evaluated arthritis index, arthritis incidence and joint edema, and measured body weight, spleen size and stenosis rate, serum cytokine level, serum antibody level, immune cell populations In spleen, lymph node, and knee joint, and performed histological analysis of CIA mouse joint. Results : In the AR-P group, arthritis index, arthritis incidence and joint edema were decreased, and the enlargement, malformation and stenosis of spleen and the malformation of joint appeared milder than the control group. In AR-P group, the levels of $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, $IFN-{\gamma}$ in serum were significantly decreased. And the level of anti-collagen II in serum was maintained lower in AR-P group than in the control group. In AR-P group, the level of $IFN-{\gamma}$ and IL-10, and $IFN-{\gamma}/IL-4$ ratio were significantly decreased, and the ratios of $CD3e^+$ cells to $CD45^+$ cells, $CD4^+$ cells to $CD8^+$ cells in spleen were similarly maintained as those of the normal group. In the AR-P group, the populations of $CD4^+/CD25^+$ cells in spleen and lymph nodes, $CD45R^+/CD69^+$ cells in lymph nodes, $CD3^+/CD69^+$ cells and $CD11b^+/Gr-1^+$ cells in knee joint were decreased. In the histological analysis, the cartilage destruction, synovial cell proliferation and the collagen fiber destruction were decreased in the AR-P group Conclusions : The results suggest that AR-P at right ST36 has a therapeutic effect on collagen-induced arthritis in mice.

Acetyl-L-carnitine (ALC), an endogenous component of the L-carnitine family, is a naturally existing molecule synthesized from L-carnitine (LC) by carnitine acetyl transferase. ALC has been shown to improve the cognitive performance of patients suffering from dementia of the Alzheimer's type and proposed for treating Alzheimer's disease in pharmacological doses. The purpose of the present study was to evaluate the bioefuivalence of two ALC tablets, $Nicetile^{TM} (Dong-A Pharmaceutical Co.) and $L-Cartin^{TM}$ (Kuhn Il Pharmaceutical Co.), according to the guidelines of Korea Food and Drug Administration (KFDA). The ALC release from the two ALC tablets in vitro was tested using KP VII Apparatus II method in various dissolution media (pH 1.2, 6.0 and 6.8). Twenty six normal male volunteers, $24.46\pm3.67$ years in age and $64.45\pm5.54$ kg in body weight, were divided into two groups and a randomized $2\times2$cross-over study was employed. After one tablet containing 500 mg of ALC was orally administered, blood was taken at predetermined time intervals and the concentrations of ALC in serum were determined using HPLC with fluorescence detector. Because of the presence of endogenous ALC, the calibration was performed using dialyzed serum. The dissolution profiles of the two ALC tablets were similar in all the dissolution media. The pharmacokinetic parameters such as $AUC_t,\;C_{max}\;and\;T_{max}$ were calculated and ANOVA was utilized for the statistical analysis of the parameters. The results showed that the differences in $AUC_t,\;C_{max}\;and\;T_{max}$ between two tablets were $0.35\%,\;0.93\%\;and\;2.34\%$ respectively, when calculated against the $Nicetile^{TM} tablet. The powers $(1-\beta)\;for\;AUC_t$ , and Cmax were $98.72\%\;and\;85.48\%$, respectively. Minimum detectable differences $(\Delta)\;at\;\alpha=0.05\;and\;1-\beta=0.8$ were less than $20\%,\;(e.g.,\;13.21\%\;and\;18.42\%\;for\;AUC_t,\;and\;C_{max}$ respectively). The $90\%$ confidence intervals were within $\pm20\%\;(e.g.,\;-7.38\sim8.09\;and\;-9.86\sim11.72\;for\;AUC_t,\;and\;C_{max}$, respectively). These two parameters met the criteria of KFDA for bioequivalence, indicating that $L-Cartin^{TM}$ tablet is bioequivalent to $Nicetile^{TM} tablet.

This paper described the ultimate strength and deformation limit of new uniplanar T-joints in cold-formed square hollow sections. The new T-joint had the configuration that only a branch member was oriented at 45 degrees to a chord member in the plane of the truss. This study focused on the branch-rotated T-joints governed by chord web failure. Based on the test results of the T-joint in cold-formed square hollow sections, the deformation lirnit was found to be 3%B for $16.7{\leq}2(B/T){\leq}33.3$ and $0.63{\leq}(b_1/B)=0.7$. Existing strength formulas for traditional T-joint were investigated, and the new strength formula for the branch-rotated T-joint was proposed. This proposed formula was based on column buckling theory considering the rounded corners of cold-formed square hollow sections. Finally, the optimization condition of yield stress and $2{\gamma}$ was recommended to select the optimized chord section.
