Effect of FK506 on fibroblast counts and scar area in sciatic nerve anastomosis of rats. (a) The area of scar tissue for each rat was defined as the mean scar area of six sections and the data were expressed as mean±S.D. in mm2. *P<0.05, **P<0.01 compared with the area of scar tissue in normal control group. #P<0.05, compared with that in model group. (b) Fibroblast counting was expressed as the number per counting area. *P<0.05, **P<0.01 compared with the number of fibroblast in normal control group. #P<0.05, compared with that in model group. (c) Correlation between scar area and fibroblast number (linear correlation analysis). The scar area (mm2) was apparently positively correlated with the fibroblast number (number per counting area; r=0.9915, P<0.0001)
