The Effects of Parathyroid Hormone Applied at Different Regimes on the Trochanteric Region of the Femur in Ovariectomized Rat Model of Osteoporosis

Figure 3

Analysis of fluorescence apposition bands in transversal sections from the subtrochanteric region of rat femur. The sections (all sections 15 mm distal from femoral head) were studied by fluorescence microscopy. In the OVX group, we could mainly observe a periosteal activity. In the sham group, only a minimal periosteal bone formation could be seen. The PTH e2d-treated animals showed weaker endosteal appositions in comparison to the PTH 5x/w animals.
