| 目的 制备牛血清白蛋白（BSA）温敏凝胶给药系统，并考察给药系统的释放情况。方法 以温敏凝胶材料普朗尼克F127为载体，以相变温度为指标，通过倒置试管法筛选普朗尼克F127的浓度。通过BCA蛋白定量试剂盒法测定BSA的含量。以PBS缓冲液为释放介质，考察凝胶给药系统中BSA的释放。结果 浓度为20%（w/v）的普朗尼克F127凝胶的相变温度为23℃，载入BSA后相变温度不变。BSA在普朗尼克F127凝胶系统中的释放12h可释放80%以上，具有缓释效果，且释放接近零级动力学过程。结论 BSA-普朗尼克F127温敏凝胶系统制备方法简单，具有明显的缓释效果。 |

| Objective To study on the preparation of bovine serum albumin (BSA) loaded temperature-sensitive gel and the release property of BSA.Methods Pluoronic F127 was selected as carriers.The concentration of pluoronic F127 was optimized through the inverted test tube method using the phase-transition temperature as the index.The concentration of BSA was determined using BCA kits.The release property of BSA was investigated using PBS as the dissolution media.Results The phase-transition temperature of pluoronic F127 with the concentration of 20% (w/v) was 23℃ and retained identically when BSA was loaded.The results of release showed that after 12h,more than 80% of BSA was released and the release property was nearly zero-order kinetics.Conclusion The preparation technique of BSA loaded pluoronic F127 temperature-sensitive gel is feasible.The release of BSA could be well controlled. |
