Therapeutic effect of tripterine on adjuvant arthritis in rats

AIMS OF THE STUDY: Tripterygium wilfordii Hoog f., a perennial vine, is used in traditional Chinese medicine for treatment of rheumatoid arthritis. This study was to determine whether tripterine, isolated from Tripterygium wilfordii Hoog f., had therapeutic effects on adjuvant arthritis. MATERIALS AND METHODS: Adjuvant arthritis (AA) was induced in rats on day 0. Tripterine 5, 10 and 20 mg kg(-1)day(-1), or prednisone 10 mg kg(-1)day(-1) was given to rats intragastrically from day 19 to day 24. RESULTS: Tripterine significantly inhibited paw swelling and bone destruction in AA rats. Serum level of IgG anti-Mycobacterium tuberculosis antibodies and delayed-type hypersensitivity (DTH) induced by Mycobacterium tuberculosis were also decreased by tripterine. The effects of tripterine were associated with decreased interleukin-1beta (IL-1beta) mRNA expression in ankle joint synovial membrane and tumor necrosis factor-alpha (TNF-alpha) mRNA expression in homogenized paws from adjuvant-induced arthritic rats. CONCLUSIONS: These findings suggested that tripterine had a therapeutic effect on adjuvant arthritis.     

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.

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.
