Abstract

OBJECTIVE

To investigate the effects of the decoction of Rhizoma Dioscoreae septemlobae (RD) on the biomechanical and bone histomorphometric parameters of femur in the ovariectomized rats.

METHODS

25 female Wistar rats without pregnancy and deliver were divided into 5 groups randomly: sham (sham-operation), ovariectomy (OVX), OVX + high dosage RD (4 g/kg x d), OVX + middle dosage RD (2 g/kg x d) and OVX + low dosage RD (1 g/kg x d), n = 5 in every group. After intragastric administration 12-week period continuously, the biomechanical and the bone histomorphometric parameters of the femur of the rats in every group were determined, respectively, including percentage of trabecular bone volume (TBV%), percentage of trabecular osteoid (TOS%), mean osteoid width (MOSW), percentage of mineralizing surface (MdS%), percentage of double mineralizing surface (DMds%), percentage of DMds/MdS (%), percentage of travecular formation surface (TFS%), percentage of trabecular resorption surface (TRS%), mineral apposition rate (MAR), mineralizing lag time (MLT).

RESULTS

The maximum loading, deflection, the maximum strain of the femur in the OVX group was 125.78 +/- 15.48 (N), 1.87 +/- 0.22 (mm), 9.34 +/- 1.10 (%), it was significantly lower than that in the sham group (P< 0.05, P < 0.01), respectively. The maximum loading and maximum stress was increased in different extent in the every dose group of OVX + RD, respectively. TBV% of femur was significantily lower in the OVX group than that in the sham group (P < 0.01). The MdS%, DMds%, DMds/MdS (%), TOS%, MOSW, TRS%, MAR was significantly higher in the OVX group than that in the sham group, respectively (P < 0.01). In the RA high and middle dosage group, the TBV% of femur was significantly higher than that in the model group (P < 0.05), and the MdS%, DMds%, DMds/MdS (%), TRS%, TOS%, MOSW, MAR was significantly lower than that in the model group, respectively (P < 0.05), and MLT was decurtated slightly (P > 0.05).

CONCLUSION

The decoction of RD can decline the bone turnover and the loss of bone of femur in the ovariectomized rats.
