          摘   要  目的  研究接骨木新品种盐丹对大鼠骨折愈合的影响。方法  将SD大鼠随机分为假手术组、模型组、中华跌打丸组(0.54
          g/kg)、野生接骨木组(5.4 g/kg,以生药量计)和盐丹高、中、低剂量组(10.8、5.4、2.7 g/kg,以生药量计),每组12只。除假手术组外,
          其余各组大鼠制备股骨骨折模型。于术后第2天起,各组大鼠灌胃相应药物和蒸馏水,每日1次,连续8周。于给药2、4、8周后,检
          测大鼠血清中钙、磷、碱性磷酸酶(ALP)和骨钙素(OCN)水平,利用 Micro-CT 扫描评价骨折股骨形态和骨微结构参数[骨密度
         (BMD)、骨体积/组织体积(BV/TV)、骨小梁数量(Tb.N)、骨小梁分离度(Tb.Sp)、骨小梁厚度(Tb.Th)],采用苏木精-伊红染色观察
          骨组织骨折处的形态变化。结果  与模型组比较,盐丹高剂量组大鼠给药2、4、8周后血清中钙水平(给药4周除外)均显著降低,
          磷、ALP、OCN水平均显著升高(P<0.05);骨折部位可见骨性骨痂形成、骨折断端连接、骨折线逐渐模糊或消失、骨髓腔开通等骨
          修复过程,骨组织骨折处可见大量肉芽组织、成纤维细胞、软骨细胞、新生骨小梁以及新生骨板等;给药 8 周后的 BMD、BV/TV、
          Tb.N、Tb.Th均显著升高,Tb.Sp显著降低(P<0.05)。野生接骨木组上述大部分指标变化不明显。结论  盐丹具有促进大鼠骨折愈
          合的作用,且作用优于野生接骨木。

          ABSTRACT    OBJECTIVE To investigate the effect of a new variety of Sambucus williamsii Hance Yandan on the healing in rats
          with  fractures.  METHODS  SD  rats  were  randomly  allocated  to  sham  surgery  group,  model  group,  Zhonghua  dieda  pill  group
         (0.54  g/kg),  wild  S.  williamsii  group (5.4  g/kg,  using  raw  drug  dosage),  and  high-,  medium-,  and  low-dose  groups  of Yandan
         (10.8,  5.4,  2.7  g/kg,  using  raw  drug  dosage),  with  12  rats  in  each  group.  Except  for  the  sham  surgery  group,  the  remaining
          groups were prepared with a femoral fracture model. Starting from the second day after surgery, each group was intubated with the
          corresponding drugs and distilled water once daily for 8 consecutive weeks. At 2, 4, and 8 weeks after administration, the levels of
          calcium,  phosphorus,  alkaline  phosphatase (ALP),  and  osteocalcin (OCN)  in  rat  serum  were  detected.  Micro-CT  scanning  was
          used  to  evaluate  the  morphology  and  bone  microstructural  parameters  of  the  fractured  femur  [bone  mineral  density (BMD),  bone
          volume/tissue  volume (BV/TV),  trabecular  number (Tb.N),  trabecular  separation (Tb.Sp),  trabecular  thickness (Tb.Th)],  and
          hematoxylin-eosin  staining  was  adopted  to  observe  the  morphological  changes  at  the  bone  fracture  site.  RESULTS  Compared  with
          the model group, the levels of calcium in rat serum were significantly decreased (except at 4 weeks after administration), and the
          levels of phosphorus, ALP, and OCN were significantly increased (P<0.05) at 2, 4, and 8 weeks after administration in the high-
          dose  group  of Yandan;  bone  callus  formation,  connection  of  fracture  ends,  gradual  blurring  or  disappearance  of  the  fracture  line,
          and opening of the marrow cavity were observed in the bone repair process, and a large amount of granulation tissue, fibroblasts,
          chondrocytes, new trabeculae, and new bone plates were visible at the fracture site of bone tissue; after 8 weeks of administration,
          BMD,  BV/TV,  Tb.N,  and  Tb.Th  were  significantly  increased,  and  Tb.Sp  was  significantly  decreased (P<0.05).  Most  of  the
          above  indicators  in  the  wild  S.  williamsii  Hance  group  showed  no  significant  changes.  CONCLUSIONS  Yandan  has  the  effect  of
          promoting fracture healing in rats, and its effect is superior to that of wild S. williamsii.
