Evaluation of Osseointegration Ability of Porous Polyethylene Implant (Medpor) Treated with Chitosan

Figure 7

The whole and local tomography of histologic images of the Medpor plates implanted into skulls of 3 rabbits at 3 weeks after surgery. All bone tissue sample was stained with H&E dye. The images of original Medpor are on left column (a, b, c, and d) and the images of Medpor soaking with chitosan are on right column (a′, b′, c′, and d′). Same alphabet means same rabbit (ex. a = a′). Image of (d) is zooming in local part of (c), and (d′) is zooming in local part of (c′). The pink color means alive new bone tissue which provides strong osseointegration ability with host bone tissue.
