關節潤滑液,可覆蓋於人工關節表面,並形成足以抵抗關節間磨耗的保護膜。其主要成分包含了蛋白質、脂質、玻尿酸等。可想見的,不同成分所混合的潤滑液會具有不同的摩擦特性,也相對影響到潤滑薄膜所表現出的物理特性。 迄今為止,尚無完整的研究去了解人工關節於關節中之潤滑機制,因此在本研究中,將不同成分混合的潤滑液及其相應的物理特性量化與分析。亦從臨床上收集到的關節潤滑液作為對照,以評估正常標準的摩擦係數。同時藉由分析跟評估相關數據來判定幾項主要影響人工關節摩擦特性的變因。 本研究中同時分析比較了SDS-PAGE和ELISA所得到的實驗數據。藉由蛋白質電泳影像可以半定量的特性建立較為經濟且快速的檢測、定量系統,也可做為量化評估實行人工關節置換手術其必要性的參考依據,並有助於評估不同病症之病患最適當的治療方式,以期達到最佳的治療效果。
The synovial fluid is squeezed as a lubrication thin film to protect the articulating materials in the artificial joint system. Various compositions such as proteins, lipids, hyaluronic acid are contained in the synovial fluid. Therefore, the lubrication thin film properties from various compositions are critical to the tribological properties of artificial joint materials. In this research, we are going to retrieve the synovial fluids for quantitative analysis of various compositions. The friction coefficients of the collected synovial fluids will be measured as well. By doing so, we are able to obtain the critical factors affecting the tribological behaviors of artificial joint system. The purpose of this research was compared SDS-PAGE image analysis with ELISAs. The research outcome can further assist to develop the medical grade lubricating additives for arthroplasty in order to improve the performance of artificial joints.
