目的
2
研究接骨木新品种盐丹对大鼠骨折愈合的影响。
方法
2
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
2
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
2
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。
OBJECTIVE
2
To investigate the effect of a new variety of
Sambucus williamsii
Hance Yandan on the healing in rats with fractures.
METHODS
2
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
2
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 proce
ss, 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
2
Yandan has the effect of promoting fracture healing in rats, and its effect is superior to that of wild
S. williamsii
