Abstract: AIM: To investigate the immune therapeutic effect of a small amount of oral soluble chicken collagen type Ⅱ (SCC Ⅱ) on adjuvant arthritis (AA) in rats.METHODS: The ConA-induced the proliferative responses of splenocytes, mesenteric lymph node cells(MLNCs) and peyer' s patche cells(PPCs), IL-1 and TNFαproductions in the supernatants of peritoneal macrophages(PMΥ) and synovial membrane cells (SMCs) combined with the changes of the indices such as ankle joint secondary inflammatory responses, thymus indices and so on in AA rats were assayed or observed.RESULTS: SCC Ⅱ(0.03, 0.30 and 3.00 mg·kg-1·d-1, d 12-18, ig) could improve the overreduced ConA-induced splenocyte proliferative responses, but further reduced those of MLNCs and PPCs, inhibited the IL-1 and TNFαproductions in PMΥand SMCs, and ameliorated the secondary inflammatory responses in AA rats.CONCLUSION: A small amount of oral SCC Ⅱ(ig) have the immunotherapeutic effect on AA in rats.
