Chondroprotective Effects and Multitarget Mechanisms of Fu Yuan Capsule in a Rat Osteoarthritis Model

Figure 1

Histological analysis of articular cartilage sections. (a) Hematoxylin-eosin staining of knee joint sections in the control group showed a smooth surface and a clear laminar structure in the articular cartilage. By contrast, the cartilage surface in the model group was rough with some superficial leakage and ulcers. Furthermore, Fu Yuan Capsule-treated cartilage showed fewer lesions compared with the model group (magnification, 200x). (b) Mankin’s score of articular cartilage. Data are expressed as mean ± SD. compared with the control group; compared with the other groups.
