				        	Objective To study the effect of type Ⅱ collagen (C Ⅱ) from Zaoeys dummies (Cantor)on the immune functions of rats with collagen-induced arthritis and to understand the mechanisms of RA treated with Zaoeys dhumnades (Cantor).Methods The rats with collagen-induced arthritis were randomly divided into three group:C Ⅱ from Zaocys dhumnades,bovine C Ⅱ and arthritis control group,a normal control group was set up,too.Every group had 7 rats.The C Ⅱ from Zaocys dhumnades and the bovine C Ⅱ group were fed with C Ⅱ from Zaocys dhumnades (15 mg/kg) and bovine C Ⅱ (15 mg/kg) per day respectivelyfor 15 days.The CD4/CD8 subset ratio,serum levels of anti-C Ⅱ antibody,TNF-a,IL-10,IL-1 and IL-4 in.rats were measured.Results In the arthritis group,CD4/CD8 subset ratio (P<0.05) and serum levels of type Ⅱ collagen antibody (P<0.01) and TNF-a (P<0.01) were significant increased and IL-10 (P<0.01) was significantly decreased.In the C Ⅱ from Zaocys dhumnades and bovine C Ⅱ group,CD4/CD8 subset ratio (P<0.05) and the level of TNF-a (P<0.01) were significantly decreased compared with the arthritis group,and had no difference compared with the normal group.The level of anti-C Ⅱ antibody was declined significantly compared with the arthritis group (P<0.05) and had statistical difference with the normal group (P<0.01).The level of IL-10 was significantly increased(P<0.01),but lower than the normal group(P<0.05).There was no statistical difference in the level of IL-1 and IL--4 in.all four groups.Conclusion C Ⅱ from Zaoeys dhum-nades (Cantor) is as effective as bovine C Ⅱ in modifying the immune functions of collagen-induced arth-ritis in rats.They can decrease the level of anti-C Ⅱ antibody,the level of TNF-a,CD4/CD8 subset ratio and increase the level of IL-10 in the peripheral blood of rats with collagen-induced arthritis.C Ⅱ from Zaocys dhumnades may be one of the important pharmacological active components that have the potential in treating rheumatoid arthritis.
