Figure 2

Explanted cranial tibial muscle of a rabbit after implantation of MgCa0.8 for 6 weeks. The former position of the screw head is marked by the black circle. To obtain cross sections of the central implantation site for histological and immunohistochemical studies, the muscle was cut into halves first, then one piece of the distal part was embedded in paraffin. The vertical black lines indicate which part of the muscle was used.
