Abstract

Aim: We synthesized MgO NPs via sol-gel reaction and investigated them as carriers to deliver Mg²⁺ to the affected joint for osteoarthritis (OA).Materials & methods: The physicochemical properties of samples were characterized by transmission electron microscope (TEM), dynamic light scattering (DLS) and x-ray diffraction (XRD). The release of Mg²⁺ was monitored by ICP-MS. The potential cytotoxicity was evaluated using MTT assay. The efficacy and biosafety were evaluated in a rabbit OA model.Results: MgO NPs can prolong the Mg²⁺ release time from 0.5 h to 12 h. No significant cytotoxicity was observed when concentrations below 250 μg/ml. Intra-articular samples could effectively alleviate the degeneration and destruction of the cartilage.Conclusion: this study demonstrates the potential of MgO NPs as a safe and effective treatment of OA. Simultaneously, the size of the particles may play a significant role in influencing the therapeutic outcome.

氧化镁纳米粒子的溶胶凝胶合成及其作为骨关节炎治疗剂的评估。

目的：我们通过溶胶-凝胶反应合成了氧化镁 NPs，并研究了将其作为载体将 Mg2+ 输送到受影响关节以治疗骨关节炎（OA）。材料与方法：透射电子显微镜（TEM）、动态光散射（DLS）和 X 射线衍射（XRD）对样品的理化性质进行了表征。ICP-MS 监测了 Mg2+ 的释放。使用 MTT 试验评估了潜在的细胞毒性。在兔 OA 模型中评估了药效和生物安全性。研究结果当浓度低于 250 μg/ml 时，未观察到明显的细胞毒性。关节内样本可有效缓解软骨的退化和破坏。结论：本研究表明氧化镁氧化物具有安全有效治疗 OA 的潜力。同时，颗粒的大小可能会对治疗效果产生重要影响。
