Histological sections (40 ×) of tarsotibial joints of left hind paw form different animal groups. A Control group showed normal synovial space (S), articular cartilage (CT), bone structure (BN) and absence of inflammatory cells; B CFA-induced arthritic group showed marked infiltration of inflammatory cells, synovial hyperplasia and marked reduction in synovial joint (shown by arrow); C prednisolone-treated group and D dry latex of C. procera-treated group showed less inflammatory cell infiltration, minimal synovial hyperplasia and modest reduction in joint space
