摘要
目的 通过猕猴舌下—舌神经移位移植后的病理改变，证实舌神经移位移植后运动神经可以再生，舌肌可以重建其动力功能的临床应用价值。方法 采用 Ｈ Ｅ 常规染色，嗜银，髓鞘特殊染色及免疫酶标记、透射电镜，观察不同时期神经移位移植后舌肌的组织反应及神经重建状况，测定肌纤维中羟脯氨酸的含量。结果 神经移植３ 月、６ 月、１２ 月粘膜未见萎缩，舌肌间肌纤维萎缩以舌前份较为明显， Ｓ－ １００ 蛋白染色显示肌束及肌纤维间可见神经纤维，较对照侧少，随时间延长，其间神经纤维逐渐增多，神经吻合处神经纤维排列紊乱，处于再生修复状态，嗜银、髓鞘染色及透射电镜观察均证实远颅端神经再生现象，舌肌内羟脯氨酸的含量测定对照侧小于实验侧，实验侧其含量术后随时间延长逐渐降低。结论 舌下—舌神经移位移植的方法是可行的，病理学证实神经可以再生修复。
Objective To use the concentrated APF foam to prevent caries safely and effectively.Methods The bovine enamel was treated with 5000ppm APF foam,while the application consequence of 5000ppmAPF foam was increased.The anticaries effects of 5000ppm and 12300ppm APF foam were tested to see whether a reduction in concentration was possible.Results When 5000ppm APF foam application frequeney was increased,the lesion depth in enamel was shallow,the demineralization degree was lighter,the anticaries effects were equal to that of routine.Conclusion From the results of this experiment,it appears that decreasing the concentration of fluoride and increasing the application consequence of APF foam is justified.
