摘要 目的:制备大鼠骨质疏松模型,皮下注射依替膦酸钠,观察其对骨质疏松的疗效。方法:将4月龄w istar雌性大鼠61只随机分为6组:卵巢切除组(O组)、假手术组(S组)、雌二醇阳性对照组(E组)、药物注射低剂量组(L组)、中剂量组(M组)、高剂量组(H组),给药12周。测定动物子宫重量,血清钙、磷、ALP含量,骨重及骨钙、磷含量和骨形态计量等指标。结果:O组子宫重量、骨钙、磷含量及骨小梁体积和宽度均显著低于S和E组,骨干重和灰重下降;OB I升高、OC I显著增加,破骨显著大于成骨;OS、MAR及血清ALP活性等均显著增加。提示卵巢切除后由于骨再建平衡破坏,骨转换加速,骨量明显丢失。依替膦酸钠各剂量组对子宫均无影响,其余指标与S、E组接近。结论:皮下注射国产依替膦酸钠能有效防治切除卵巢大鼠骨质疏松,对子宫无刺激作用。
