Effects of the Col II solution on cartilage and bone damage in MNX-induced osteoarthritis in rats by safranin-O stain histological analysis for cartilage repair in rat knee joints. The histological and pathological changes in rat knee joints were examined by safranin-O stain 6 weeks after MNX treatment (magnification: × 40). The red colour arrow indicates cartilage damage. The blue colour arrow indicates mild cartilage damage. The green colour arrow indicates cartilage damage preservation
