Abstract
Colchicum luteum (CL) has been traditionally used in the Unani system of medicine as a chief ingredient of many polyherbal formulations for the treatment of joint pain and rheumatoid arthritis (RA). To evaluate the antiarthritic activity of CL hydroalcoholic extract (CLHE) in formaldehyde and complete Freund's adjuvant (CFA) induced arthritis. Arthritis was induced by administration of either formaldehyde (2% v/v) or CFA into the subplantar surface of the hind paw of the animal. Joint swelling was measured on days 8, 9 and 10 in formaldehyde induced arthritis and days 3, 7, 14 and 21 in CFA induced arthritis. In order to evaluate the effect of CLHE on disease progression, serum TNF-α level and synovial expression of proinflammatory mediators (TNF-R1, IL-6 and IL-1β) was determined in CFA induced arthritis. CLHE produced a significant and dose dependent inhibition of joint swelling during the entire duration of the study in both, formaldehyde and CFA induced arthritis. Serum TNF-α level was also reduced significantly in a dose dependent manner in all the CLHE treated groups. The expression of proinflammatory mediators (TNF-R1, IL-6 and IL-1β) was also found to be less in the CLHE treated group as compared to control. We believe that the antiarthritic activity of CLHE was due to its modulatory effect on the expression of proinflammatory cytokine in the synovium. Our results contribute towards validation of the traditional use of CL in the treatment of RA and other inflammatory joint disorders.
    • "Oral administration of GSHE for 21 days resulted in significant reduction in joint inflammation and joint diameter. GSHE treatment showed consistent decrease in joint diameter and none of the treated groups showed an increase in joint diameter from day 14, as observed in the AIA group, which is the result of heightened cell-mediated immune response (Nair et al., 2011; Newbould, 1963). Our results clearly revealed that GSHE inhibited arthritis induced by immunization with CFA. "
    [Show abstract] [Hide abstract] ABSTRACT: Glorisa superba (GS) is amedicinal plant that has been traditionally used in the treatment of joint pain and rheumatoid arthritis (RA). The present study was carried out to investigate the antiarthritic activity of Glorisa superba hydroalcoholic extract (GSHE) in an adjuvant-induced arthritis (AIA) rat model. Arthritis was induced by sub-plantar administration of complete Freund’s adjuvant (CFA) and GSHE (25, 50, or 100 mg/kg/day) was administered orally for 21 consecutive days. Joint diameter was measured on Days 0, 3, 7, 14, and 21. GSHE dose dependently attenuates the increased joint diameter and serum tumor necrosis factor (TNF)-α level following induction of arthritis by adjuvant. This attenuation was well substantiated with reduced mRNA expression of interleukin (IL)-1β, IL-6, TNF-α, and NF-κB. Additionally, GSHE inhibited phosphorylation of the mitogen-activated protein kinases (MAPK) signaling pathway as there was decreased protein expression of MAPK (p-p38/p38 and p-ERK/ERK p-JNK/ JNK ratio). Moreover, GSHE in a dose-dependent fashion normalized the redox status of ankle joint (GSH, malonaldialdehyde [MDA], and NO levels and superoxide dismutase [SOD] and catalase [CAT] activities) and displayed decreased inflammatory cell infiltration in histopathological findings. Taken together, these findings indicate that GSHE protects against AIA by modulating MAPK

    • "The effect of indomethacin treatment on serum pro-inflammatory cytokine levels is similar to the results reported earlier. [3,4,22] This difference in effect on the cytokine profile suggests that RCAE may be having different or additional mechanisms (in comparison to indomethacin) which are responsible for its antiarthritic effect.

    [Show abstract] [Hide abstract] ABSTRACT: Introduction: Rosa centifolia L. (Rosaceae) have been used for the treatment of joint pain and rheumatoid arthritis (RA) in the traditional system of medicine. Aim: In this study, the antiarthritic activity of the alcoholic extract from the floral parts of R. centifolia was investigated. Materials and methods: The anti-inflammatory and antiarthritic activity of R. centifolia alcoholic extract (RCAE: 32, 64, and 128 mg/kg) was evaluated using the carrageenan-induced paw edema and complete Freund's adjuvant (CFA) induced arthritis model. Serum from arthritic rats was collected for the estimation of pro-inflammatory cytokine levels. Further, the safety of RCAE was evaluated in an acute and sub-acute (28-day) oral toxicity study. Results: RCAE (64 and 128 mg/kg) significantly (P < 0.01) inhibited carrageenan-induced paw edema at 1, 3, and 6 h post carrageenan challenge and demonstrated significant (P < 0.01) antiarthritic activity on days 3, 7, 14, and 21 day following CFA immunization. Further, RCAE (128 mg/kg) treatment also produced a significant (P < 0.01) decrease in circulating pro-inflammatory cytokine levels as compared with control. Further, no toxicologically significant treatment-related effects were observed in the oral sub-acute toxicity study conducted with the extract. Conclusion: The result of study demonstrates the antiarthritic activity of R. centifolia and validates its traditional use for the treatment of RA.

    • "The inhibition of formaldehyde induced joint edema is one the most suitable methods to evaluate antiproliferative activity and screen anti arthritic agents. The injection of formaldehyde into rat paw produced localized inflammation and pain which is biphasic in nature i.e as early neurogenic component followed by a later tissue mediated response (Nair et al. 2011; Owoyele et al. 2011). Polyprenol inhibited the proliferative global edematous response to formaldehyde in dose dependent manner, suggesting that it may alter certain aspects of the inflammatory response similar to that of aspirin with possible antiarthritic potential.
