- Paper Abstract
- Ethnopharmacological relevance: Zanthoxylum piperitum has been used as a traditional Asian medicine to treat hypertension, stroke, bruise and muscle pain. It has been known to induce detoxification; affect anti-bacterial, anti-oxidant, and tyrosinase activity; inhibit osteosarcoma proliferation; anti-osteoarthritis inflammation. In this study, we aim to identify the therapeutic effect of Z. piperitum 90% EtOH extract (ZPE-LR) on rheumatoid arthritis. Material and methods: We investigated the anti-rheumatoid arthritis and -immunomodulatory activities of the ZPE-LR in collagen-induced arthritic (CIA) mice, a rheumatoid arthritis animal model. In order to assess the analgesic effects of ZPE-LR in vivo, acetic acid injection, formaldehyde injection, hot plate model was used. The mechanism for anti-inflammatory activity of ZPE-LR was identified with LPS-stimulated Raw 264.7 cells. Results: Pharmacologically, oral administration of ZPE-LR into CIA mice resulted in a significant and dose-dependent decrease in clinical arthritis score and paw swelling compared to untreated negative control. Pathologic examination showed that ZPE-LR prevented morphological change in cartilage and destruction of phalanges in CIA mice. This protective effect was associated with reduced pain, inflammatory mediators such as NO, TNF-α, IL-1β, and IL-6, as well as COX-2 and iNOS expression. Furthermore, reduction of phosphor-ERK and BDNF indicates a novel rheumatoid arthritis-regulating mechanism by ZPE-LR treatment. Conclusions: These data suggest that the administration of ZPE-LR remarkably inhibited CIA progression and might be helpful in suppressing inflammation and pain in rheumatoid arthritis.
