Therapeutic effects and mechanisms of total flavonoids of Turpinia Arguta Seen on adjuvant arthritis in rats

AIM: To investigate the therapeutic effects and mechanisms of total flavonoids of Turpinia Arguta Seen (TFS) on adjuvant arthritis in rats. METHODS: The model of adjuvant arthritis was induced by injection of Freund's Complete Adjuvant (FCA). Secondary paw swelling of AA rats was measured with volume meter and polyarthritis index were scored. The splenocyte proliferation, (interleukin-1) IL-1 and interleukin-2 (IL-2) production were assayed by cell proliferation assay. Prostaglandin E(2) (PGE(2)) production was determined by radioimmunoassay. RESULTS: TFS (80, 160, 320 mg/kg, i.g.) could significantly inhibit secondary inflammatory reaction (secondary swelling, multiple arthritis, pathologic change of ankle arthritis) in AA rats. The results in vivo showed that the low response of splenocytes to concanavalin A (Con A) and lipopolysaccharide (LPS) and the decreased IL-2 synthesis were restored in AA rats treated with TFS (160, 320 mg/kg, i.g.), while the elevated IL-1 and PGE(2) released from peritoneal macrophages (PMphi) were also reduced. CONCLUSION: TFS has significant therapeutic effect on AA rats, which might be relate to its immunoregulatory actions.

Effects and mechanisms of total glucosides of paeony on adjuvant arthritis in rats

Total glucosides of paeony (TGP) is the major active constituent of Paeonia lactiflora Pall. The present study was carried out to investigate the effects of TGP on adjuvant arthritis (AA) of rat and its possible mechanisms. AA was induced by metatarsal footpad injection with complete Freund's adjuvant in male Sprague-Dawley rats. The secondary inflammatory reaction was evaluated by hind paw swelling, polyarthritis index. Activity of interleukin-1 (IL-1) was detected by Con A-induced thymocytes proliferation of C57BL/6J mice assay. The tumor necrosis factor alpha (TNFalpha), prostaglandin E(2) (PGE(2)) and cyclic adenosine monophosphate (cAMP) levels in synoviocytes were assessed by radioimmunoassay (RIA). PGE(2) receptors, EP2 and EP4, were analyzed by Western blot analysis. The level of IL-6 was measured by ELISA. Intragastric administration of TGP (50,100 mg/kg) significantly decreased secondary inflammatory reaction in AA rats. Suppressing the activity of IL-1 and TNFalpha, decreased PGE(2) and increased cAMP levels in synoviocytes of AA rats were observed after administration of TGP. In the immunoblot analysis, TGP could up-regulate the expression of EP2 and EP4. These results showed TGP significantly inhibited the progression of AA, and the inhibitory effects might be associated with its ability to mediate the level of cAMP and inhibit the production of IL-1, TNFalpha, IL-6 and PGE(2) from activated synoviocytes.

Therapeutic effects of daphnetin on adjuvant-induced arthritic rats

AIM OF THIS STUDY: Daphnetin was regarded as the mark compound for quality control of Zushima-Pian, a traditional Chinese medicine tablet for treating rheumatoid arthritis (RA). However, no in vivo study on the therapeutic effects of daphnetin for RA has been reported. MATERIALS AND METHODS: The adjuvant arthritic (AA) rat model was developed to evaluate the anti-arthritic effects of daphnetin. After immunized with Freund's complete adjuvant (FCA), the rats were treated with daphnetin (2.25 and 4.5mg/kg) for three weeks. We determined the change of secondary paw swelling and the arthritis scores of these tested rats. The severity of arthritis in the knee joints was evaluated by histological assessment of cartilage destruction. The levels of IL-1, TNF-alpha and MIF in the serum were measured by ELISA. RESULTS AND CONCLUSIONS: Our results showed that daphnetin significantly reduced paw swelling and decreased the arthritis scores. The pathological examination demonstrated that articular cartilage degeneration with synovial hyperplasia and inflammatory cells infiltration in AA rats were suppressed by daphnetin. There was significant reduction in production of interleukin-1 (IL-1), tumor necrosis factor (TNF-alpha) and macrophage migration inhibitory factor (MIF) in serum of AA rats treated with daphnetin except the low dose group (2.25mg/kg) on TNF-alpha. In conclusion, we demonstrates that daphnetin is highly effective on preventing and suppressing the development and progression of adjuvant-induced arthritis and provides direct evidences that daphnetin is one of the active principle of Zushima-Pian for treating rheumatoid arthritis.
