Objective. Rebampide is a gastroprotective agent used to treat gastritis. It possesses anti-inflammatory and anti-arthritis effects, but the mechanisms of these effects are not well understood. The objective of this study was to explore mechanisms underlying the therapeutic effects of rebamipide in inflammatory arthritis. Methods. Collagen-induced arthritis (CIA) was induced in DBA/1J mice. DBA/1J mice were immunized with chicken type II collagen, then treated intraperitoneally with rebamipide (10 mg/kg or 30 mg/kg) or vehicle (10% carboxymethylcellulose solution) alone. Seven weeks later, plasma samples were collected. Plasma metabolic profiles were analyzed using ultra performance liquid chromatography/quadrupole time-of-flight mass spectrometry-based metabolomics study and metabolite biomarkers were identified through multivariate data analysis. Results. Low dose rebamipide treatment reduced the clinical arthritis score compared with vehicle treatment, whereas high dose rebamipide in CIA aggravated arthritis severity. Based on multivariate analysis, 17 metabolites were identified. The plasma levels of metabolites associated with fatty acids and phospholipid metabolism were significantly lower with rebamipide treatment than with vehicle. The levels of $15-deoxy-^{{\Delta}12,14}$ prostaglandin J2 and thromboxane B3 decreased only in high dose-treated groups. Certain peptide molecules, including enterostatin (VPDPR) enterostatin and bradykinin dramatically increased in rebamipide-treated groups at both doses. Additionally, corticosterone increased in the low dose-treated group and decreased in the high dose-treated group. Conclusion. Metabolomics analysis revealed the anti-inflammatory effects of rebamipide and suggested the potential of the drug repositioning in metabolism- and lipid-associated diseases.

Objective : The purpose of this study was to investigate the effects of Aurothiomalate acupuncture containing Sodium Aurothiomalate on Type II collagen-induced arthritic DBA/1 mice. Methods : The mice were divided into three groups, one control group and two test groups. The control group was injected with saline on Choksamni(ST36) and the two test groups were injected either with Aurothiomalate acupuncture into Choksamni(AT1 group), or with Aurothiomalate acupuncture into Hwando(G30, AT2 group). We measured the incidence of arthritis, the mean index of arthritis, the number of arthritic limbs for the clinical examination and evaluation. We also examined the changes in the level of TNF-$\alpha$ and IL-$1{\beta}$. Results : 1. The incidence of arthritis in mice of the AT1 and AT2 groups were significantly lower than that of the control group. 2. The mean indices of arthritis in mice of the AT1 and AT2 groups were significantly lower than that of the control group. 3. The mean number of arthritic limbs in mice of the AT1 and AT2 groups were significantly lower than that of the control group. 4. The levels of TNF-$\alpha$ of the mice in the AT1 and AT2 groups were significantly different from that of the control group. 5. The levels of IL-$1{\beta}$ of the mice in the AT1 and AT2 groups were not significantly different from that of the control group. Conclusion : These results indicate that the treatment with Aurothiomalate acupuncture could improve the clinical status of Arthritis by suppressing immune responses in the mice of Type II collagen-induced arthritic.

Laboratory inbred mice are used widely and commonly in biomedical research, but inbred mice do not have a big enough gene pool for the research. In this study, genetic and morphometric analyses were performed to obtain data on the characteristics of a newly developing inbred strain (KWM/Hym) captured from Chuncheon, Korea. All of five Korean wild male mice have the zinc-finger Y (ZfY) gene. Also, all of 19 Korean wild mice used in this analysis have the AKV-type murine leukemia virus gene, indicating that Korean wild mice might be Mus musculus musculus. To identify the genetic polymorphism in KWM/Hym, SNP analysis was performed. In a comparison with 28 SNP markers, there was a considerable difference between KWM/Hym and several inbred strains. The homogeneity between KWM/Hym and the inbred strains was as follows: C57BL/6J (39.3%), BALB/c AJic (42.9%), and DBA/2J (50%). KWM/Hym is most similar to the PWK/PhJ inbred strain (96.4%) derived from wild mice (Czech Republic). To identify the morphometric characteristics of KWM/Hym, the external morphology was measured. The tail ratio of male and female was $79.60{\pm}3.09$ and $73.55{\pm}6.14%$, respectively. KWM/Hym has short and agouticolored hairs and its belly is white with golden hair. Taking these results together, KWM/Hym, a newly developing inbred mouse originated from wild mouse, might be use as new genetic resources to overcome the limitations of the current laboratory mice.

Cirsium japonicum var. ussuriense is often used in treatment of human disease such as hemorrhage, blood congestion and inflammation. The present study has been undertaken to investigate the effect of the leaf extract from C. japonicum var. ussuriense (CLE) on the development of collagen-induced arthritis (CIA) in DBA1/J mice. CLE administration suppressed markedly the arthritis incidence and arthritis score in CIA mice. Also, CLE significantly suppressed the release of $PGE_2$, TNF-${\alpha}$, IL-4 and IL-6 in CIA mice. However, CLE significantly increased the production of IL-10, but not IL-4. These results suggest that CLE suppress inflammatory mediators and regulates Th1 and Th2 cytokines. These properties may contribute to the anti-arthritis action of CLE.

The potential therapeutic action of shikonin in an experimental model of rheumatoid arthritis (RA) was investigated. As a RA animal model, DBA/1J mice were immunized two times with type II collagen. After the second collagen immunization, mice were orally administered shikonin (2 mg/kg) once a day for 35 days, and the incidence, clinical score, bone mineral density (BMD), bone mineral content (BMC) and joint histopathology were evaluated. BMD in the proximal regions of the tibia largely increased in the shikonin treatment group compared with the control group. We also examined the effect of shikonin on inflammatory cytokines and cartilage protection. Shikonin treatment significantly reduced the incidence and severity of collagen-induced arthritis (CIA), markedly abrogating joint swelling and cartilage destruction. Shikonin also significantly inhibited the production of matrix metalloproteinase (MMP)-1 and up-regulated tissue inhibitors of metalloproteinase (TIMP)-1 in mice with CIA. In conclusion, shikonin exerted therapeutic effects through regulation of MMP/TIMP; these results suggest that shikonin is an outstanding candidate as a cartilage protective medicine for RA.
