Bone grafts are very significant for the reconstruction of the trauma and the deformations created thereafter. Various bone forming and promoting agents are widely studied. Hence, in this study, we aim to evaluate the osteoinduction effect of scaffold impregnated with Simvastatin in wistor rats in an observational study.
We implanted 18 Wistar rats to be equally divided as controls and test groups. Polycaprolactone coated with 20 mg concentration of Simavastatin under sterile condition was used as test and hydroxy appetite as control. Then, we observed the histopathological Heamatoxilin and Eosin and ABH, sections at 4, 12, and 26 weeks. We noted the calcium deposition and bone formation.
We observed a significant variation among groups at 4, 12, and 26 weeks in the calcium deposition. While for the bone formation no significant variation were noted among groups at 4 and 12 weeks, however, there was a significant difference noted at 26 weeks. At the end of 12 weeks, mild fibroblast proliferation was seen in the surrounding area. After 26 weeks, ABH sections showed focal area of fibroblast proliferation with mild mononuclear infiltration was noticed; but implant could not be located.
We conclude that Simavastatin showed an anabolic effect on bone healing.
骨移植对于创伤修复及后续形成的畸形矫正非常重要。各种骨形成和促进剂都得到了广泛研究。因此,在本研究中,我们旨在通过一项观察性研究评估在Wistar大鼠中,负载辛伐他汀的支架的骨诱导作用。
我们植入了18只Wistar大鼠,并将其平均分为对照组和试验组。在无菌条件下,使用涂有20毫克浓度辛伐他汀的聚己内酯作为试验材料,羟基磷灰石作为对照。然后,我们在第4、12和26周观察组织病理学苏木精和伊红染色以及ABH切片,记录钙沉积和骨形成情况。
我们观察到在第4、12和26周时,各组之间的钙沉积存在显著差异。在第4周和12周时,各组之间的骨形成没有显著差异,但在第26周时存在显著差异。在12周结束时,在周围区域可见轻度成纤维细胞增殖。26周后,ABH切片显示有成纤维细胞增殖的局部区域,并伴有轻度单核细胞浸润,但未找到植入物。
我们得出结论,辛伐他汀对骨愈合具有合成代谢作用。
