ABSTRACT
Objective:
To establish a pristine-induced rheumatoid arthritis model in mice,and to evaluate its histological and immunological distinction.Methods:
Thirty female BALB/c mice,6-8 weeks old,were randomly divided into 2 groups,a control group and pristine group.The mice in pristine group were injected intraperitoneally with 0.5 ml pristine three times at 0,9,and 18 weeks, while mice in the control group receiving saline at the same time.Arthritis score and paw thickness were measured and histopathological assessment of joint sections was performed.The expression of phagocytes,dendritic,neutrophils,T and B cells markers in spleen were determined by flow cytometry.Results:
In model-marking group,11 mice were presented with macroscopic evidence of arthritis such as erythema or swelling.The paw thickness in pristine-induced mice was significant higher than that in the control groups[(2.90±0.51) mm vs(1.29±0.47 mm),P<0.05].In addition,arthritis score in pristine-induced mice was 9.55±2.80 at 21 weeks after first injection with 0.5 ml pristine.H&E staining revealed a significant increase of synovial inflammation, cartilage and bone destruction after stimulated with pristine.Meanwhile,the expression levels of CD11b,CD11c,GR1,CD4,CD8 and CD154 were obviously increased in model-marking group when compared with that in control group.Conclusion:
The pristine-induced model presents the similar histological and immunological distinctions with human rheumatism arthritis,which can mimic the pathogenesis of rheumatism arthritis.
