中文摘要 本研究目是開發設計一個能穩定控制藥物釋放的多功能性骨關節鈦植入物系統。對於人工關節,伴隨著植體之植入,通常會有導致發炎反應及細菌感染的發生,因此有文獻指出使用藥物載體,將藥物直接送達目標處,且持續釋放藥物,使得植體植入後有最直接的藥物治療,也可以降低人體對於藥物所需的含量,減輕身體負擔。
鈦和鈦合金經常使用於骨外科植入物,因為它們具有良好的生物相容性,無毒性和好的機械性能。以燒結方式將鈦珠粉末塗佈於鈦金屬人工關節上之技術已發展成熟,經燒結方式鍵結上多孔性鈦珠表面具有良好的粗糙度及孔隙率外,鈦珠表面亦具有良好之表面積。另外利用微弧氧化(micro-arc oxidation, MAO)一簡單且具成本效益的生物陶瓷技術,在表面形成多孔、耐磨耗及抗腐蝕陶瓷相硬化膜。由於多孔表面結構有相當重要的骨整合性,能有效使骨生長至其表面,以增加自然骨與植體間介面的機械咬合性,進一步提供骨內生長的特性,使增生的骨質能進入多孔鈦間隙,達到良好固定效果。而後使用drop-dry法將含有藥物之溶液滴在試片表面,使藥物於孔洞內及表面,以利藥物攜帶。完成後使用聚乳酸具甘醇酸(polylactic acid-polyglycolic acid, PLGA)一種長效型生物可降解高分子和聚麩胺酸(gamma polyglutamic acid, -PGA)為一親水性佳且可降解高分子,作為表面塗層,此高分子薄膜可以有效調控抗生素於身體內之釋放速率及藥量,進而達到長效型藥物釋放之效果。
最後進行藥物釋放、抗菌、生物親和性等測試。在藥物釋放部分,將製備好的試片浸泡於模擬體液中,於不同時間點收取其溶液,並使用UV-Vis進行吸光值測定。在抗菌測試方面,使用金黃色葡萄球菌,初步結果由抑菌環及紫外光/可見光光度法分析,證實藥物不僅成功地攜帶並隨時間連續且穩定的釋放。生物親和性部分,藉由細胞活性測試及觀察細胞型態,證實適當的藥量對於細胞的活性及增生是不影響的。
以上結果證明,此物遞送系統兼具有前期抗菌抗發炎、中期促進骨生長及後期骨內生長之特性,並且可以廣泛應用在組織工程及藥物學等各種應用上。
英文摘要 Total hip arthroplasty (THA) is an established procedure to restore mobility and to improve quality of life in patients that suffer from severe osteoarthritis or femoral fractures in close proximity to the hip joint. The technology of sintering coated titanium (Ti) bead on titanium prosthesis has been developed for many years. The porous surface of the sintered titanium beads has good roughness and porosity to induce better bone ingrowth. After implantation the formation of a bacterial surface biofilm and compromised immunity at the implant/tissue interface may lead to persistent infections around titanium implants. So far, extensive inflammation and poor osseointegration have been identified as the major reasons for early orthopedic implant failures. In this study, we focus on the development of a polymer-coated ceramic composite for antimicrobial drug delivery. A micro-arc oxidation (MAO) was used to produce a porous structure comprising calcium acetate hydrate (Ca(CH3COO)2•H2O) and sodium phosphate monobasic monohydrate (NaH2PO4•H2O) for improving the biocompatibility of titanium. Using a drop-dry method aqueous drug was loaded into the porous surface. Finally, Polylactic acid-polyglycolic acid (PLGA), a biodegradable polymer and Poly gamma glutamic acid (-PGA) were coated through spin coating as a barrier to control drug release. The use of PLGA film can effectively regulate the release rate and amount of the antibiotic dose within the body. The phenomenon of inflammation or infection decreased for the effect of long-circulated drug release.
The bactericidal effect of antibiotic on the porous surface was evaluated by using MRSA bacteria (SA10780). Additionally, the results obtained from UV-Vis analysis suggested that the drug was successfully filled into coatings and released over time with antibiotic/Polymer solution, which could provide a high bactericidal effect against MRSA by the bactericidal effect of antibiotic. These findings demonstrate that using porous structure with PLGA and -PGA is promising as cost-effective drug delivery formulation for delivering drugs locally and continuously. Furthermore, antimicrobial study demonstrates that the antimicrobial activity of antibiotic toward the growth inhibition of a bacterium model of MRSA is not compromised after being loaded into the porous structure.
We demonstrate the preparation and characteristics of Ti implants with a layer of MAO porous coating that have extended drug release properties, biocompatibility for human osteoblasts and potentially improved antibacterial properties. With the reserved drug activity, the porous structure based drug delivery system may find various applications in tissue engineering and pharmaceutical science.
