摘要


本實驗利用原花青素為天然交聯劑,以製備膠原蛋白、透明質酸、三鈣磷酸鹽複合式填補材料 (CHTP)。在材料物性分析部分,首先以不同交聯程度的膠原蛋白材料透過固定指數進行交聯程度評估,之後以最適化交聯程度的 CHTP 複合材料,利用機械強度、含水率以及生物降解速率測定來評估其材料特性。生物相容性部分則以類骨母細胞 ( MG-63) 細胞進行體外測試。 經 5% 原花青素交聯後的複合材料 (CHTP-5%) 具有很高的澎潤度 (420%) 與機械強度 (40 kPa),經三十天之體外降解測試後仍有60%以上餘重。體外生物適應性結果亦顯示,CHTP-5% 複合材料對於 MG-63 細胞具有促進增生之效用。由材料機械性質、澎潤度、降解速率以及體外生物適應性等實驗結果顯示, CHTP-5% 複合材料為一具潛力的填補材料。

並列摘要


In this study, composite restoration materials (CHTP) made of type I collagen, hyaluronic acid (HA) and tricalcium phosphate (β-TCP) were prepared and crosslinked with the natural crosslinking agent, oligomeric proanthocyanidins (OPCs). The crosslinking property was evaluated. The mechanical strength, swelling ratio and in vitro degradation rate of the optimally crosslinked CHTP composite were investigated. In vitro tests were carried out to evaluate the biocompatibility using MG-63 cell line. Results indicated that the crosslinked composite using 5% OPCs solution (CHTP-5%) had high swelling ratio (420%) and mechanical strength (40 kPa), and remained more than 60% weight after 30 days in vitro degradation test. The results of in vitro tests showed that CHTP-5% would promote the proliferation of MG-63 cell. The results of material analyses and in-vitro tests showed that CHTP-5% composite is of great potential to serve as a useful bone restoration material.
