Abstract
退化性關節炎是一種緩慢漸進式的退化性疾病,目前治療關節炎藥物的研究重點,在於進一步修飾已知傳統藥物之官能基,使其成為具有改善連結組織結構(CTSMAs)以及減緩關節炎症狀之藥物(DMODs)。國外臨床上四環黴素(DC)已普遍使用於治療關節炎,它能抑制第一型介白素B(IL-1B) 和基質金屬蛋白酶類(MMPs)的生合成,也能改善subchondrobone的組織結構,長期使用能有效的治療關節炎。關節腔直接注射玻尿酸(HA)亦是目前臨床上廣泛用於治療關節炎的方式,可抑制MMPs的表現及促進醣胺聚醣(GAG)生成外,亦具備高黏度與黏彈的特性,給予關節物理性的保護並提供止痛的效果。本篇論文是利用鋅離子連結DC及玻尿酸,於外科手術引發關節炎之紐西蘭白兔做關節腔直接注射法來驗證HA-DC膠體是否具備協同之治療效果。本次研究結果顯示,此HA-DC膠體能提供較佳之黏彈性質,並具有止痛功能;此巨型網狀結構使得HA不易被降解,可延緩並增強藥物保護關節軟骨之效果。而關節軟骨染色與切片的結果更顯示,使用HA-DC膠體之組別具有較正常之關節軟骨分佈,只產生少量的磨損裂縫及骨刺,顯示此藥物產生修復與抑制軟骨降解之效果;且相較於單獨使用HA或DC顯示了更佳的治療效果。這些實驗結果符合我們先前一系列的細胞實驗與膠體備製測試,數據皆顯示此HA-DC膠體結構確實能有效減緩關節炎症狀並提供良好之止痛效果。
