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.
