Bee venom (BV) has been traditionally applied to relieve pain and to cure inflammatory diseases such as rheumatoid arthritis (RA) and neuritis. While several investigators have evaluated the anti-inflammatory effect of BV treatment, the anti-nociceptive effect of BV treatment on inflammatory pain is not reported. Therefore, we decided to evaluate the analgesic effect of BV treatment using Freund's adjuvant induced chronic arthritis model. Freund's adjuvant-induced arthritis has been used as an experimental animal model for RA in humans to assess the efficacy of the anti-inflammatory/analgesic drugs. In this study, subcutaneous BV treatment (1mg/kg/day) produced significantly reductions of symptoms related to arthritic pain (i.e. mechanical hyperalgesia and thermal hyperalgesia). The anti-nociceptive effect of BV was observed from at least 12 days after BV treatment. Furthermore, BV treatment significantly suppressed adjuvant induced Fos expression in lumbar spinal cord. We also found that local injection of BV into near the inflammatory site (especially Zusanli-acupoint) showed more potent analgesic effect on arthritic pain rather than distant injection of BV from inflammatory site (arbitrary side of back). The present study demonstrates that BV treatment has anti-nociceptive effect on arthritis induced inflammatory pain. The analgesic effect of BV on RA is probably mediated by the effect of BV itself or possible other mechanism such as counter-irritation. Furthermore, it is possible that BV acupuncture is one of the promising candidates for long-term therapy of RA.

Anti-inflammatory, anti-arthritic and analgesic activity of each herbal extract, which is extracted from Bacopa monnieriis, Cassia fistula and Phyllanthus polyphyllus, respectively. The treatment of herbal extract exhibited anti-inflammatory effect as a dose-dependent manner, from 1.25 mg/kg to 12.5 mg/kg, in acute inflammatory models (carrageen and egg-albumin induced rat hind paw edema). It also elicited significant anti-inflammatory activity in chronic inflammatory models (cotton pellet granuloma and Freund's adjuvant induced polyarthritis in rat). In cotton pellet granuloma test, the extract exhibited the inhibitory effect of 23 and 57% at the dose of 6.25 and 12.5 mg/kg, respectively. In Freund's adjuvant induced model, the treatment of the extract of 1.25, 6.25 and 12.5 mg/kg showed the inhibitory effect of 23, 56 and 66% at 8 days, respectively. In the acetic acid-induced model, the extract significantly reduced abdominal writhing in mice when compared to the control group, reducing the mean number of writhing from $41{\pm}2$ in the control group to $17{\pm}3$ and $15{\pm}2$ at the dose of 6.25 and 12.5 mg/kg. From these experiments, the extract, which was extracted from the combination of Bacopa monnieriis, Cassia fistula and Phyllanthus polyphyllus, (w/w/w = 1/2/1) is surprisingly found a significant analgesic and anti-inflammatory activity.

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.

Gold sodium thiomalate (GST, gold compound) is a widely used anti-arthritic, anti-rheumatic and anti-inflammatory drug that is considered a good alternative to sodium salicylate (NaSA) for individuals who cannot tolerate salicylates. Nitric oxide (NO) synthesized by inducible nitric oxide synthase (iNOS) has been implicated as a mediator of inflammation. Recent evidence suggests that anti-inflammatory effect of NaSA lies in the inhibition of iNOS, but nothing has been reported about the direct effect of iNOS expression by GST. The present study was designed to elucidate sequentially the action mechanisms of GST and NaSA on lipopolysaccharide (LPS) plus interferon-gamma (IFN-$\gamma$) induced iNOS expression in RAW 264.7 macrophages. Both GST and NaSA inhibited NO production and iNOS protein expression in a dose dependent manner. GST inhibited iNOS mRNA expression induced by LPS plus IFN-$\gamma$, whereas NaSA did not. These findings suggest that GST may exert anti-arthritic, anti-rheumatic and anti-inflammatory effect by inhibiting iNOS expression induced by LPS plus IFN-$\gamma$ at transcriptional level, whereas NaSA exert its effect by inhibiting iNOS expression at the translational or posttranslational level.

Phytoceramide (Pcer) is found mainly in plants and yeast. It can be neuroprotective and immunostimulatory on various cell types. In this study, the therapeutic effect of Pcer was explored using the carrageenan/kaolin (C/K)-induced arthritis rat model and fibroblast-like synoviocytes (FLS). Pcer treatment (1, 10, and 30 mg/kg/day) were given to the arthritic rats for 6 days after disease induction. Weight distribution ration (WDR), knee thickness, squeaking score, serum levels of proinflammatory mediators, and histological analysis were measured and performed to evaluate arthritic symptoms in the rat model. In interleukin (IL)-1β-stimulated FLS, proinflammatory mediators were measured after Pcer (1-30 µM) treatment. Arthritic symptoms in rats with Pcer treatment were significantly decreased at days 4 to 6 after C/K arthritis induction. Inflammation in the knee joints were also significantly decreased in rats with Pcer treatment. Furthermore, in IL-1β-stimulated FLS, the expressions of proinflammatory mediators were also inhibited by Pcer. As shown by the results, Pcer has anti-arthritic effects in the C/K rat model and in synovial cells, suggesting that Pcer has the potential to be a useful agent in arthritis treatment.

In Northeast Asia, Paeoniae Radix has been used in treatments of inflammation-causing diseases such as arthritis for many centuries. Paeoniflorin, one of the principle bioactive monoterpene glucosides from the paeony root, is reported to be mostly responsible for the effectiveness of the treatments. However, the anti-inflammatory effect of a monoterpene, paeoniflorigenone (PFG) which partially has the moiety of paeoniflorin minus a glucose structure is unknown. Thus, the aim of this work was to investigate anti-inflammatory activity of PFG. For the investigation, PFG activity on the NO (nitric oxide) production from LPS-stimulated macrophages, and the anti-inflammatory effect was tested in the animal model of septic arthritis caused by Candida albicans, a major etiological agent for septic arthritis. For induction of the arthritis, mice were administered with an emulsion of C. albicans cell wall (CACW) mixed with Complete Freund's Adjuvant (CFA) via footpad-injection (Day 0); PFG at a dose of 0.5 or 1 mg/mouse (25 or 50 mg/kg of body-weight) was given to the animals on Day 3, 6, and 9; footpads were scored for arthritis. Moreover, the PFG effect on proliferation of T-lymphocyte that causes aggravation of arthritis was additionally tested. Data resulting from those tests showed that PFG inhibited the NO production from the stimulated macrophage in a dose dependent manner (P<0.05), indicating that PFG is an anti-inflammatory. To confirm the in-vitro results, anti-inflammatory activity of PFG was determined against C. albicans-caused septic arthritis. Data showed that PFG-treatment reduced footpad-swelling which indicates that PFG has anti-arthritic effect (P<0.05), which is therapeutic. The anti-arthritic effect appeared to be mediated by PFG suppression of T-cell proliferation. Ultimately, PFG, a monoterpene component, has anti-inflammatory activity analogous to paeoniflorin. The anti-inflammatory activity treats the septic arthritis due to a pathogenic fungus C. albicans.

Objectives: To investigate anti-inflammatory and anti-arthritic effects of Gyulpidaehwangbakcho-tang (GDBT) extract in a murine model of rheumatoid arthritis. Methods: The mice received $100{\mu}g$ of bovine type II collagen in Freund's complete adjuvant by intradermal injection at the base of the tail on day 0 and a booster injection on day 21. The mice were orally administered with GDBT (200 or 50mg/kg dissolved in distilled water) daily from day 1 to day 21 after arthritis incidence, and monitored for disease incidence and the severity of arthritis up to day 21. In order to evaluate the effect of GDBT on disease progression, we examined pro-inflammatory cytokines including IL-$1{\beta}$, IL-6, TNF-${\alpha}$, COX-2 and NOS-II. Results: GDBT produced a significant and dose dependent inhibition of arthritis and inflammation during the entire duration of the study. This action was characterized by the decreased production of IL-$1{\beta}$, IL-6, TNF-${\alpha}$, COX-2, and NOS-II in vivo. Conclusion: We believe that the anti-arthritic activity of GDBT is due to its modulatory effect on the expression of pro-inflammatory cytokine in the synovium. Our results contribute towards validation of the traditional use of GDBT in the treatment of RA and other inflammatory joint disorders.

This study was conducted to investigate the effect of an anti-inflammatory and analgesic action of the glucosamine HCl (Glucosamine) and SH-1 (Glucosamine + Oriental herbal composition combined group). Male sprague-Dawley rats $(200{\sim}250g)$ and ICR mice $(20{\sim}30g)$ were randomized and these experimental groups were divided into 4 groups. Two control group were given as negative control (saline) and positive control (Ibuprofen, 100 mg/kg) and two groups given as oral administration of Glucosamine (320 m/kg) and SH-1. Carrageenan induced paw edema test, hot plate method, croton oil induced granuloma, capillary permeability test and acetic acid writhing syndrome were also shown to be comparable in the SH-1 group to anti-inflammatory drug group such as positive control group (Ibuprofen). Although further studies should be performed to confirm the effects of SH-1, present results suggest that the combined administration of SH-1 have potential action in anti-inflammatory and analgesic action. It could be applicable for the improvement of arthritic symptoms as a new diet-supplement.

We evaluated the anti-arthritic effect of a new diet-supplement product containing red ginseng, glucosamine, shark cartilage, ascorbic acid and manganese chloride for the relieving arthritic symptoms. Anti-inflammatory activities of the aqueous extract of red ginseng (250 and 500 mg/kg), glucosamine (240 mg/kg) and shark cartilage (240 mg/kg) were tested individually on vascular permeability and carrageenan-induced paw edema. Glucosamine and shark cartilage showed the inhibition of vascular permeability by 29.6 and 32.9%, respectively. Red ginseng (500 mg/kg) and shark cartilage showed the inhibition of carrageenan-induced paw edema at 0.5, 1, 2 and 3 hr. The supplement (red ginseng mixture: RGM) composed of red ginseng (43.5%), glucosamine (25.0%), shark cartilage (25.0%), ascorbic acid (5.0%) and manganese chloride (1.5%) was prepared and its inhibitory activities including vascular permeability and carrageenan-induced paw edema were comparable to anti-inflammatory drugs such as diclofenac and ibuprofen. It was also tested on adjuvant-induced arthritis in rats as one of chronic arthritic tests and Randall-Selitto assay as an analgesic test. RGM showed the inhibition against the swelling of rat paws induced by Mycobacterium tuberculosis at a dose of 1,500 mg/kg. Determination of cytokines of the sera sampled from arthritis-induced animals indicated that RGM increased the levels of $interferon-{\gamma}$ and interleukin-6, representing the immunostimulatory effect by red ginseng. RGM treatment moderately reduced the production of NO in RAW 264.7 cells in a dose-dependent manner. Taken together, these results support that RGM can be applicable for the improvement of arthritic as a new diet-supplement.

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.
