PTH (80 μg/kg per day (hPTH), s.c., 4 weeks ) induces a ~35% recovery of this loss and a ~40% reversal of the associated decreases in trabecular number (Tb.N) and connectivity. PTH also causes a shift from single to double calcein-labeled trabecular surfaces, a significant enhancement in the mineralizing perimeter and a respective 2- and 3-fold stimulation of the mineral appositional rate (MAR) and bone formation rate (BFR).
