ABSTRACTObjective: Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation in joints. Ageratum conyzoides L. (Babandotan)leaves are proven to be used in inflammation therapy, yet there is a little data regarding the effects of the leaves on RA. The aim of this study is toinvestigate anti-RA activity of the ethanolic extract of A. conyzoides L. leaves (EEAL) harvested from Bogor, Indonesia, in rats.Methods: The phytochemical screening analysis and thin-layer chromatography were performed to analyze the constituents of the EEAL. This studyused white male Sprague Dawley rats which were divided into 6 groups; normal control and negative control groups, both given 0.5% carboxymethylcellulose; the positive control group, given methotrexate suspension (0.05 mg/200 g bw.); the dose variation extract is 40 mg, 80 mg, and 160 mg/200 gbody weight. All the groups were induced with 0.1 ml Complete Freund’s adjuvant on day 1, except normal control group. Some parameters will bemeasured, such as paw edema, levels of leukocyte and lymphocyte, concentrations of tumor necrosis factor-α (TNF-α), and the number of osteoclastsper mm2.Results: For 21 days the rats have given treated the EEAL in three doses, was showed the decreasing volume of paw edema, levels of blood leukocytesand lymphocytes, concentrations of TNF-α and the number of osteoclasts, compared to the rat model of RA.Conclusion: This study showed that the leaves of A. conyzoides L. harvested from Bogor, Indonesia, have activity as anti-RA in a rat model, in whichflavonoid plays a role in inhibition of chronic inflammatory processes.Keywords: Ageratum conyzoides L. leaves, Anti-rheumatoid arthritis, Complete Freund’s adjuvant, Flavonoids.

This study was to investigate the antinociceptive effects of moxibustion in a complete Freund's adjuvant (CFA)-induced arthritic rat model, and the effects of moxibustion on immunohistochemical changes at the spinal cord level. Moxibustion was applied to the ipsilateral (right) Zusanli (ST36) acupoint to the lesion side for 9 days to CFA-induced arthritic rats. The stepping force was measured as a behavioral test, c-Fos immunohistochemistry, NO production and nNOS Western blots were examined to evaluate antinociceptive effects. Moxibustion at ST36 significantly improved the stepping force in the affected hind limb in CFA-induced arthritis. Moreover, moxibustion at ST36 suppressed the production of NO and the protein expression of c-Fos and nNOS induced by arthritis. These results suggest that moxibustion at ST36 has a potent antinociceptive effect in an arthritic rat model, and modulates neuronal excitability and endogenous NO production by suppressing c-Fos and nNOS protein expression.
