Chang-Back-San and Chil-Mi-Chang-Back-San have been used for the treatment of neuralgia and arthritis in traditional medicine. The anti-inflammatory activities of Chang-Back-San and Chil-Mi-Chang-Back-San water extract (CBSE and CCBSE) on the carrageenin induced edema, Corton oil induced granuloma pouch, and adjuvant arthritis in rats were examined. The analgesic effects of the CBSE and CCBSE were also investigated utilizing acetic acid induced writhing syndrome in mice. The oral administration of CBSE and CCBSE showed to have the anti-inflammatory activities in 1% carrageenin induced edema in rats. They also showed significant inhibitory effects on granuloma and exudate formation in rats. In the method of adjuvant arthritis, they orally administered for 19 days, inhibited the hind paw edema in rats from 3rd day to 19th day, especially CCBSE has the efficacy more than CBSE. They significantly decreased the number of writhing syndromes induced by acetic acid in mice. In the present study, CBSE and CCBSE were indicated to have the anti-inflammatory and analgesic activities.

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.

In order to access the suppressive effects of piroxicam (PX) and hydrolyzed products of Scutellariae Radix (PSH) on arthritis, we investigated whether PSH gel could suppress the progression of collagen-induced arthritis. PX, one of nonsteroidal anti-inflammatory drugs has been used in the systemic and topical treatment in a variety of inflammatory conditions. Scutellariae Radix, one of the herbal medicines, was used for the purpose of anti-inflammatory and anti-bacterials. For the purpose of transdermal absorption of the hydrogel preparations, two classes of hydrogels (PX, PSH) were formulated with carbomer 940, diethylene glycol monoethyl ether, polyethylene glycol-8-glyceryl caprylate/caprate and triethanolamine. In carrageenan-induced edema in rat hind paws, inhibition of foot swelling was more increased in PSH than PX hydrogel. Rheumatoid factors including serum IgG, IgM and collagen specific antibody were present much lower in PSH gel treated mice than control. Histological examination revealed that PSH hydrogel inhibited infiltration of inflammatory cells into affected paw joint, compared with control. The PSH hydrogel would be a suitable preparation to increase transdermal treatment for anti-inflammatory effects on collagen-induced arthritis.

This study evaluated the anti-inflammatory potential of the crude alkaloidal fraction (CAF) of methanol extract of Solanum trilobatum Linn. (Solanacea) root in animal models of inflammation. Crude alkaloidal fraction at doses of 25, 50 and 100 mg/kg significantly (p < 0.01) reduced carrageenan induced rat paw volume at 3 h after carrageenan challenge as compared to control group of animals. CAF (25, 50 and 100 mg/kg) significantly (p < 0.01) and dose dependently suppressed cotton pellet induced granuloma formation. Topical application of CAF (1, 5 and 10 mg/ear) markedly inhibited multiple application of TPA in mice. CAF elicited pronounced inhibitory effects on formaldehyde and adjuvant induced arthritis in rats. These results indicate that CAF of methanol extract of the Solanum trilobatum has anti-inflammatory activity in acute and chronic inflammation.

Objectives : The present study was undertaken to evaluate whether Atractylodis Rhizoma Alba ethanol (ARA-E) extract, which is the pericarp of $Atractylodes$ $japonica$ Koidz. has an effect on collagen-induced arthritis (CIA) in mice. Methods : Male DBA/1J mice were induced by intradermal injection of bovine collagen-II in Freund's incomplete adjuvant (IFA). The CIA mice in the onset of arthritis were treated daily with oral administration of ARA-E extract at dose of 50 mg/kg/bw for 28 days. Arthritis index, histopathological changes and the levels of anti-type II collagen (CII) IgG and inflammatory cytokine, TNF-${\alpha}$ in sera of mice were measured to evaluate the antiarthritic effect of ARA-E. Results : ARA-E extract significantly decreased the arthritic scores and inhibited pathological changes of knee joint tissues in CIA mice. ARA-E extract also significantly decreased the serum levels of anti-CII IgG and TNF-${\alpha}$ in CIA mice. These results indicate that ARA-E extract may effectively prevent arthritic damages in CIA mice, at least partially, by inhibiting the production of autoantibodies and inflammatory cytokine. Conclusions : This studies suggest that ARA-E has a therapeutic potential in inflammatory joint diseases such as rheumatoid arthritis.

Rheumatoid arthritis is characterized by the focal loss of cartilage due to an up-regulation of inflammatory pathways, which produce inflammatory mediators, such as interleukin-1beta(IL-$1{\beta}$), IL-6, tumour necrosis factor alpha(TNF-$\alpha$), prostaglandin, and nitric oxide(NO). We investigated the anti-arthritic effects of water extract from FLOS LONICERAE(FLWE) in vitro and in vivo. Extract inhibited the production of inflammatory mediators(NO, IL-$1{\beta}$, TNF-$\alpha$, and prostaglandin $E_2$) and the expression of inducible NO synthase(iNOS) and cyclooxygenase-2(COX-2) in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages in a dose-dependent manner. FLWE also inhibited TNF-$\alpha$, IL-$1{\beta}$, IL-6, and $PGE_2$ production as well as COX activity in collagen-induced mouse arthritis. Moreover, FLWE significantly suppressed collagen-induced mouse arthritis. These results suggest that FLOS LONICERAE may be useful for therapy against inflammatory immune diseases and rheumatoid arthritis, probably by suppressing the production of inflammatory mediators.

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.

The anti-inflammatory effect of Spirulina fusiformis on monosodium urate crystal-induced inflammation in mice has been investigated and compared with the non-steroidal anti-inflammatory drug Indomethacin. The paw volume, lysosomal enzyme activities, lipid peroxidation, anti-oxidant status and inflammatory mediator tumour necrosis factor-$\alpha$ were studied in control and monosodium urate crystal-induced mice after oral administration of Spirulina platensis in an experimental model for gouty arthritis. In the induced mice, the levels of lysosomal enzymes, inflammatory mediator tumour necrosis factor-$\alpha$, lipid peroxidation and the paw volume increased significantly, whereas the antioxidant status decreased when compared to control mice. $\beta$-glucuronidase and lactate dehydrogenase level were also found to be increased in untreated monosodium urate crystal-incubated polymorphonuclear leucocytes. After the oral administration of Spirulina fusiformis, the physical and biochemical changes observed in monosodium urate crystal-induced animals were significantly restored to near normal levels. The results clearly indicated the anti-inflammatory role of Spirulina fusiformis, a promising drug for gouty arthritis.

We recently demonstrated that bee venom (BV) injection into acupoint (i.e. Zusanli) produced more potent anti-inflammatory and antinociciptive effect in Freunds adjuvant induced rheumatoid arthritis (RA) model as compared with that of non-acupoint injection(i.e back). However, the precise components underlying BV-induced antinociceptive and/or anti-inflammatory effects have not been fully understood. Therefore, we further investigated the anti-arthritic effect of BV after extracting the whole BV according to solubility (water soluble: BVA, ethylacetate soluble: BVE). Subcutaneous BVA treatment (0.9 mg/kg/day) into Zusanli acupoint was found to dramatically inhibit paw edema and radiological change (i.e. new bone proliferation and soft tissue swelling) caused by Freunds adjuvant injection. In addition, the increase of serum interleukin-6 by RA induction was normalized by the BVA treatment as similar with that of non-arthritic animals. On the other hand, BVA therapy significantly reduced arthritis induced nociceptive behaviors (i.e., nociceptive score for mechanical hyperalgesia and thermal hyperalgesia). Furthermore, BVA treatment significantly suppressed adjuvant induced Fos expression in the lumbar spinal cord at 3 weeks post-adjuvant injection. However, BVE treatment (0.05 mg/kg/day) has not any anti-inflammatory and anti-nociceptive effect on RA. Based on the present results, we demonstrated that BVA might be a effective fraction in whole BV for long-term treatment of RA-induced pain and inflammation. However, it is clear necessary that further fraction study about BVA was required for elucidating an effective component of BVA.
