Case analysis   Rheumatoid arthritis rat model

Rheumatoid arthritis (RA) is characterised by chronic inflammation and by the destruction of synovial joints, leading to joint deformity and disability. Currently, there is no preventive treatment or cure for RA. Animal models of rheumatoid arthritis are used extensively in research on pathogenesis of inflammatory arthritis and in the pharmaceutical industry in the testing of potential anti-arthritic agents.

Caracteristics

The ankle joint and toe are swollen. The expression levels of serum TNF-N, IL-2, IL-6, IL-1 and other inflammatory factors were higher in RA model than control. The inflammation around the joint and soft tissue cause synovial hyperplasia, cartilage destruction.
