Figure 2From: Protective effects of calcium gluconate on osteoarthritis induced by anterior cruciate ligament transection and partial medial meniscectomy in Sprague–Dawley ratsHistopathological observations of the tibial and femoral articular cartilage. Of sham controls (A, B), OA controls (C, D), and the diclofenac sodium (E, F) or calcium gluconate 100 mg/kg (G, H), 50 mg/kg (I, J), and 25 mg/kg (K, L)-treated groups. Histopathological changes were markedly inhibited by calcium gluconate. Arrows indicate the thickness of tibia or femur articular cartilage; OA, osteoarthritis; gaps indicate the intra-joint space between the articular surface of the tibia and femur. Scale bar = 80 μm.Back to article page
