Abstract
抗組織沾黏隔離膜是一種用於手術中,像是引導骨再生手術,隔離組織的醫療材料。過去製做隔離膜的主要材料各自有其問題,聚四氟乙烯易包覆不全而引發併發症,且不可被生物吸收。可吸收的高分子材料容易引發患部的發炎反應。膠原蛋白則因降解速度太快,無法維持整個療程。本實驗使用羧甲基纖維素及透明質酸製做出一可吸收之隔離膜,並在其中加入鎂離子作為膜劑釋放之生長因子。
本研究使用拉力試驗機測量隔離膜之物理性質,並以MTT試驗測量各種組成比例的隔離膜對於類骨母細胞活性的影響,然後使用電子顯微鏡觀察隔離膜表面之微結構並探討其對細胞型態的影響。
根據力學性質測量結果,本研究發現隔離膜的物理性質可以藉由調控油與含水量來控制。此外,本研究亦發現於製程中加入植物油之隔離膜其表面會有孔洞性,且孔洞的性質能以羧甲基纖維素-透明質酸的比例來控制。而細胞實驗的結果顯示隔離膜中加入植物油與鎂離子可以促進細胞的生長。總體而言,我們認為以此方法製成之隔離膜以釋放生長因子是可行且具有潛力的。
