摘要:

目的: 研究仙灵骨葆联合益生菌对骨质疏松性骨折大鼠的愈合作用。方法: 将雌性SD大鼠50只随机分成5组,分别为常规骨折对照组、骨质疏松性骨折模型组、仙灵骨葆组、益生菌组、仙灵骨葆联合益生菌组,每组10只。除常规骨折对照组外,其余均切除双侧卵巢制备骨质疏松模型。6周后,每组均制备右侧股骨中段横型骨折模型。然后分别灌胃给予生理盐水、仙灵骨葆(250 mg·kg-1·d-1)及益生菌(12.5 g·kg-1·d-1)。术后5周取各组右侧股骨标本,骨密度仪测量骨密度,CR摄片和Micro-CT扫描观察股骨相关参数。酶联免疫法测定大鼠血清骨源性碱性磷酸酶(BALP)、抗酒石酸酸性磷酸酶(TRACP),显色法测定钙浓度(Ca),HE染色观察骨折骨膜组织病理变化。结果: 与骨质疏松性骨折组比较,给予仙灵骨葆或益生菌组的BALP水平增高,TRACP水平降低,骨密度和骨痂量增多,骨折线模糊,骨小梁数量和厚度增加,骨小梁间隔降低,而仙灵骨葆联合益生菌组作用最明显(P<0.05,P<0.01)。结论: 益生菌和仙灵骨葆均有促进骨质疏松性骨折愈合的治疗作用,联合用药有更佳效果。

Abstract:

AIM: To study the healing effect of Xianling GuBao (XLGB) plus probiotics on osteoporotic fracture rats. METHODS: Fifty female Sprague-Dawley rats were randomly divided into five groups: fracture control group, osteoporotic fracture model group, XLGB treatment group, probiotics treatment group and XLGB combined probiotics treatment group, 10 rats in each group. In addition to the conventional fracture control group, the other groups were treated with bilateral ovaries to prepare osteoporosis model. After 6 weeks, each group was prepared for right middle femoral fracture model. Then, Saline, XLGB (250 mg·kg-1·d-1) or probiotics (12.5 g·kg-1·d-1) were intragastrically administered separately. The right femur specimens of each group were taken 5 weeks after surgery. The bone mineral density was measured bone mineral density scanner, CR and Micro-CT were used to observe femur related parameters in rats. The bone alkaline phosphatase(BALP), tartrate resistant acid phosphatase (TRACP) contents were measured by ELISA kit, calcium(Ca)concentration was measured by biochemical analyzer. HE staining was used to observe the pathological changes of periosteum in fractures. RESULTS: Compared with the osteoporotic fracture group, the BALP level was increased, the TRACP level was decreased, the bone density and the amount of callus were increased, the fracture line was blurred, the number and thickness of the trabecular bone were increased, and the trabecular space was decreased in XLGB and probiotic group, and XLGB combined probiotic group expressed the most obvious effect of treatment (P<0.05, P<0.01). CONCLUSION: Both XLGB and probiotics showed the therapeutic effect on osteoporotic fractures, and the combination of drugs has a better effect on osteoporotic fracture.
