Microscopic pictures showing no fibrous tissue deposition in control group (A). Excessive epidural deposition of fibrous tissue is seen in laminectomy group (black arrow) with granuloma formation (yellow arrow) around spinal cord accompanied by increased thickness of dura mater that invade nervous tissue (*) in some sections (B, C). Markedly decreased epidural fibrous tissue formation (black arrow) is seen in PRF group (D). Denser epidural scar tissue formation (black arrow) is seen in Chi/Ag-NPs group (E). Very mild epidural fibrosis (black arrow) is seen in the combined PRF and Chi/Ag-NPs treatment group (F). B: Bone; S: spinal cord. MT, X: 40 bar 200 μm
