Image of fibroblast in epidural fibrosis tissue of the laminectomy sites treated with suramin of 300 mg/ml (a), 200 mg/ml (b), 100 mg/ml (c), and saline (control, d). Note that less fibroblasts were found in the 300 mg/ml suramin group (a) and 200 mg/ml suramin group (b). However, a large number of fibroblasts were found in 100 mg/ml suramin group (c) and control group (d). The magnification is ×400
