Abstract:
AIM: To observe the therapeutic effect of modified Bushen Huoxue granules (MBHG) on ovariec-tomized osteoporosis rats.METHODS: Female SD rats were randomly given sham operation (n =10) and ovariectomy, and then the model rats were further randomly divided into model group, MBHG treatment groups at doses of 200 mg/kg, 100 mg/kg and 50 mg/kg respectively, and positive control (estradiol valerate) group, with 10 rats in each group by intra-gastric administration for 12 weeks.The morphology, area, thickness, spacing and area percentage of trabecular bone in the rats were observed.The serum levels of calcium (Ca), phosphorus (P) and alkaline phosphatase (ALP) were mea-sured by automatic analyzer.Bone mineral density (BMD) was analyzed.Serum estradiol (E2 ), osteocalcin (BGP), os-teoprotegerin (OPG), receptor activator of nuclear factor-κB (RANK) and receptor activator of nuclear factor κB ligand (RANKL) levels were detected by ELISA.RESULTS: Compared with model group, trabecular bone significantly widened in all treatment groups with large number, and net-like structure restored partially.The thickness, area and area percenta-ges of trabecular bone in treatments groups were higher than those in model group,and trabecular spacing was less than that in model group (P <0.05).The serum Ca, P, E2 and OPG, and femoral BMD were significantly higher in treatment groups than those in model group, and the levels of ALP, BGP, RANK and RANKL were significantly lower than those in model group (P <0.01).CONCLUSION: MBHG has a significant therapeutic effect on ovariectomized osteoporosis rats. The mechanism may be related to the regulation of OPG and inhibition of RANKL secretion.
