目的:制备柞蚕丝素蛋白/羟基磷灰石复合支架,改善单纯羟基磷灰石(HA)支架材料的生物学特性。方法:将羟基磷灰石多孔支架材料浸泡在柞蚕丝素蛋白的水溶液中,抽真空处理48h,采取冷冻干燥法制备的方法,进行羟基磷灰石支架表面修饰。实验分为HA 支架组(单纯羟基磷灰石支架组)与(TSF/HA)柞蚕丝素蛋白/羟基磷灰石支架组。按ISO 10993标准,两组分别做体外降解实验、吸水测试及细胞粘附实验。结果:SEM镜下观察TSF/HA支架孔隙内壁上细胞粘附高于单纯HA支架,吸水率实验检测TSF-HA支架组吸水率高于单纯HA支架组,体外降解实验TSF/HA支架降解速率快于单纯HA支架,各项检测差异均有统计学意义(P<0.05)。结论: TSF/HA支架材料具有比单纯HA支架材料更优良的生物学特性,可以用于后续的实验研究。
目的:製備柞蠶絲素蛋白/羥基燐灰石複閤支架,改善單純羥基燐灰石(HA)支架材料的生物學特性。方法:將羥基燐灰石多孔支架材料浸泡在柞蠶絲素蛋白的水溶液中,抽真空處理48h,採取冷凍榦燥法製備的方法,進行羥基燐灰石支架錶麵脩飾。實驗分為HA 支架組(單純羥基燐灰石支架組)與(TSF/HA)柞蠶絲素蛋白/羥基燐灰石支架組。按ISO 10993標準,兩組分彆做體外降解實驗、吸水測試及細胞粘附實驗。結果:SEM鏡下觀察TSF/HA支架孔隙內壁上細胞粘附高于單純HA支架,吸水率實驗檢測TSF-HA支架組吸水率高于單純HA支架組,體外降解實驗TSF/HA支架降解速率快于單純HA支架,各項檢測差異均有統計學意義(P<0.05)。結論: TSF/HA支架材料具有比單純HA支架材料更優良的生物學特性,可以用于後續的實驗研究。

Objective:Prepare the artificial scaffold with tussan silk fibroin(TSF) and hydroxyapatite(HA), improve the biological properties of simple hydroxyapatite. Methods:The porous scaffolds were soaked in TSF water solution 24hours, then these scaffolds were vacuum treatment at-10℃for 48 hours and the complex scaffold----TSF/HA were gained. The scaffolds were separated into two groups, simple HA and complex TSF/HA. According to the ISO 10993 criterion,the biological properties detection included degradation in vitro, water absorption test and celladhesion test. Result:The complex TSF/HA scaffold had innumerable TSF bal on the inner wal of cells of HA under SEM. The degradation and water absorption of complex TSF/HA scaffold were obvious fast than that of simple HA (P<0.05). The celladhesion of complex TSF/HA were significantly higher than simple HA scaffold (P<0.05). conclusion:Complex TSF/HA scaffold had bet er biological properties than HA, which could be used in the subsequent experimental studies.
