Fig. 3From: Reduction of intraarticular adhesion of knee by local application of rapamycin in rabbits via inhibition of fibroblast proliferation and collagen synthesisThe collagen density of intraarticular adhesion tissue in the RAPA groups (0.2mg/ml (a), 0.1mg/ml (b), 0.05mg/ml (c) and the control group (d). The collagen tissues show blue in the section with Masson’s trichrome staining under the light microscope (×200). RAPA could reduce collagen synthesis and fibrosis. The density of collagen tissue in the 0.2 mg/ml RAPA group and the 0.1 mg/ml RAPA group revealed a significant decrease compared with those in the 0.05 mg/ml RAPA group and control groupBack to article page
