摘　　要：目的探讨恒古骨伤愈合剂对骨质疏松性骨折(osteoporotic fracture,OPF)兔骨密度(bone mineral density,BMD)及血清Dickkopf-1(DKK-1)蛋白含量的影响。方法 45只雌性日本大耳兔随机分为治疗组、OPF模型组(模型组)和空白对照组(对照组),每组15只。治疗组和模型组兔切除双侧卵巢24周证实骨质疏松后再造成左侧桡骨骨折。于骨折手术次日治疗组每2天用恒古骨伤愈合剂灌胃1次,模型组使用等量生理盐水灌胃。各组于卵巢切除术前、术后24周及术后48周行全身BMD和血清DKK-1蛋白含量测定。结果卵巢切除术后24周,模型组BMD低于对照组(P<0.05)。与模型组比较,治疗组干预后兔全身BMD提高(P<0.05),血清DKK-1蛋白含量降低(P<0.05);治疗组干预后血清DKK-1蛋白含量低于干预前(P<0.05)。结论恒古骨伤愈合剂可提高OPF兔BMD,降低血清DKK-1蛋白含量水平。Objective To explore the effect of Osteoking on bone mineral density （BMD） and serum Dickkopf-1 （DKK-1） protein levels in rabbits with osteoporotic fracture （OPF）. Methods Totally 45 female Japanese big-ear rabbits were randomly divided into the treatment group, the model group, and the blank control group （as the control group）, 15 in each group. Bilateral ovaries were ectomized for 24 weeks in the treatment group and the model group. Their left radial factures were induced after confirmed osteoporosis. Rabbits in the treatment group were administered with Osteoking by gastrogavage, once per two days. Equal volume of normal saline was given to rabbits in the model group. The general BMD and serum DKK-1 protein levels were detected before ovariectomy, at week 24 and 48 after ovariectomy. Results There was significant difference in the general BMD at week 24 after ovariectomy between the model group and the control group, and it was lower in the model group. Compared with the model group, the general BMD significantly increased and serum DKK-1 protein levels significantly decreased in the treatment group after intervention. Serum DKK-1 protein levels were significantly lower after intervention than before intervention in the treatment group. Conclusion Osteoking could improve the BMD of OPF rabbits, and reduce their serum DKK-1 protein levels as well.
