摘　　要：目的研究磁力矫治器产生静磁场对SD大鼠面颌肌细胞形态和超微结构的影响。方法本研究于2010年6月至2012年11月在昆明医学院口腔医学研究所完成。将SD大鼠面颌肌细胞加载磁场强度为971.77mT的静磁场,倒置显微镜观察细胞形态学变化,透射电镜观察细胞超微结构的改变。结果倒置显微镜观察细胞形态正常,细胞生长适应性良好;透射电镜观察细胞质游离核糖体、高尔基体、糖原、线粒体、粗面内质网和微丝均较发达。结论磁力矫治器模拟静磁场对细胞形态和细胞内部结构无损伤,其可产生促进细胞生长的生物学效应。Objective To explore the effects of the static magnetic field of magnetic functional appliance on the morphology and uhrastructure of the SD rat＇ s maxillofacial skeleton muscle cells. Methods Loading the static magnetic field with magnetic field intensity 971.77 mT on the third generation of the SD rat＇s maxillofacial skeleton muscle ceils, morphological changes were observed under inverted microscope ; uhrastructure changes were observed under transmission electron microscope. Results The cells were in normally cell morphology and good adaptability was observed by inverted microscope. The cytoplasmic free ribosomes, Golgi apparatus, glycogen, mitochoudria, rough-endoplasmic reticulum and microfilaments were observed by TEM. Conclusion The simulating static magnetic field of magnetic functional appliance has no damage to morphology and internal structure of the cells. Static magnetic fields have the biological effects of promoting cell growth.
