Figure 6

Plain radiographs and three-dimensional images of rats’ joints. (a) The plain radiographs showed that soft-tissue swelling (yellow arrows), uniform joint space narrowing (triangles), and damaged bone substance (red arrows) were markedly alleviated in the joints of rats in the APE group. (b) The three-dimensional images showed that bone destruction (red arrows) was much less robust in the APE group compared with the model and other treated groups.
