Intra-articular Injection of Baicalein Inhibits Cartilage Catabolism and NLRP3 Inflammasome Signaling in a Posttraumatic OA Model
Figure 2
Baicalein treatment ameliorated OA cartilage lesions. (a) Representative images of cartilage in the tibial plateau and femur (right knee of rats). Safranin O-Fast Green staining was performed to evaluate the relative content of proteoglycan (red color in Safranin O staining) and articular cartilage degeneration. Cartilage erosion and cartilage fibrillation were shown as black arrows. Proteoglycan loss was exhibited as a black box. Original magnification ×100 ( for each group). (b) OARSI scores assessed by two experienced observers ( for each group). Values are the ; vs. sham group. ## vs. DMM group.
