目的 评价双膦酸盐Alendronate抑制牙槽骨骨吸收的作用。方法 建立骨质疏松及牙槽骨吸收动物模型,建模术后六周,给实验组皮下注射Alendronate每周3次,共6周;用血生化指标骨生物力学、骨密度测量、组织形态学等方法进行药效评价。结果 股骨骨密度对照 组与用药组相比明显降低(P<0.01);血清碱性磷酸酶对照组与用药组相比明显升 高(P<0.01);骨生物力学各项指标实验组与对照组也有明显差异。组织形态学: 实验组牙龈轻度炎症,牙槽骨水平吸收与对照组相比明显减少;对照组牙龈乳突炎症明显, 上皮钉突增生,炎细胞浸润,牙槽骨明显水平吸收。结论 Alendron ate治疗骨质疏松有明显的疗效,能够增加骨量,阻止骨丢失;对病理性牙槽骨骨吸收有显著的治疗作用。
目的 評價雙膦痠鹽Alendronate抑製牙槽骨骨吸收的作用。方法 建立骨質疏鬆及牙槽骨吸收動物模型,建模術後六週,給實驗組皮下註射Alendronate每週3次,共6週;用血生化指標骨生物力學、骨密度測量、組織形態學等方法進行藥效評價。結果 股骨骨密度對照 組與用藥組相比明顯降低(P<0.01);血清堿性燐痠酶對照組與用藥組相比明顯升 高(P<0.01);骨生物力學各項指標實驗組與對照組也有明顯差異。組織形態學: 實驗組牙齦輕度炎癥,牙槽骨水平吸收與對照組相比明顯減少;對照組牙齦乳突炎癥明顯, 上皮釘突增生,炎細胞浸潤,牙槽骨明顯水平吸收。結論 Alendron ate治療骨質疏鬆有明顯的療效,能夠增加骨量,阻止骨丟失;對病理性牙槽骨骨吸收有顯著的治療作用。

Objective.Osteoporosis and periodontal disease animal models were used to evaluate the anti-resorption effect of alendr onate on bone.Methods.To establish osteoporosis and alveo lar bone resorption animal models.The experimental groups (ovariectomized dental ligature group and simple dental ligature group) were given alendronate in 0. 5mg/kg BW by subcutaneous injection after six weeks of ovariectomy and dental ligature,three times a week for 6 weeks.All the animals were sacrifised 12 weeks after the operation.The blood samples were collected for determination of bioch emical indexes.The left femora and jaw bone were processed for histomorphometry. The right femora and mendibles were prepared for determination of bone density and bone biodynamics.Results.As compared with the control groups (without alendronate),the values of experimental groups (with alendronate ) were all significantly improved on bone density and bone anti-curve power.The alkaline phosphatase,calcium in serum of ovariectomy groups (without alendronate ) were obviously increased.In the alendronate group,however,these indexes werec lose to normal levels.In histomorphometry,there were little inflammation in gingiva and less level alveolar bone resorption in the experimental groups;but there was obvious gingivitis and level alveolar bone resorption in the control groups .Conclusion.Alendronate can effectively treat osteoporosis,increase bone volume and prevent bone lose in ovariectomized female rats and inhibit pathological alveolar bone resorption.
