Notes:
Summary Rabbits were first immunized and later challenged with the same antigen (bovine serum albumin, or ferritin) by injection into the tibialis anterior tendon. Inflammatory changes of the tenosynovium and epitenon included infiltration by neutrophils (early) and mononuclear cells (later) over a 6-week course of tenosynovitis. A pattern of antigen entrapment in the tendon together with immunoglobulin was shown by use of radiolabelled antigen and immunochemical staining. Half-life of antigen in the tissues averaged 5 days over the 6-week period. Changes in the epitenon included cellular necrosis, appearance of phagocytic cells, and disruption of the collagen matrix. Tissues of control animals (challenged without prior immunization) showed minimal changes and significantly less retention of antigen (P〉0.005). The model is relevant to the mechanism of tendon damage associated with antigen-driven chronic inflammation, as may be the case in rheumatoid arthritis.
