| 摘 要： | 目的：了解超氧化物歧化酶（ＳＯＤ）对变链菌Ｉｎｇｂｒｉｔ、６７１５生长和粘附的影响情况。方法：用麦氏比浊法分别比较不同浓度ＳＯＤ对两种变链菌蔗糖琼脂培养基纯培养的细菌生长量；用液闪计数值比较ＳＯＤ对两种变链菌体外在羟基磷灰石（ＨＡ）上的粘附量。结果：在ＳＯＤ存在时，两种致龋菌的生长量大于没有ＳＯＤ时的生长量；ＳＯＤ作用于获得性膜和致龋菌的体外粘附过程时，两种致龋菌的粘附量显著降低，ＳＯＤ作用于致龋菌生长过程，变链菌Ｉｎｇｂｒｉｔ的粘附量升高，变链菌６７１５的粘附量显著降低。结论：外源性ＳＯＤ促进致龋菌的生长，使致龋菌的粘附量发生改变

| Abstract: | Aim: To investigate the effect of SOD on the growth and adhesion of S mutans Ingbritt and 6715. Methods: ZThe concentrations and the numbers adhered to HA of 2 strains of oral bacteria incubated with different level SOD were determined by Mc Farland colorimeter method and cpm values respectively. Results: The concentrations of 2 strains incubated with SOD were significant higher than those of strains incubated without SOD. The numbers were significant low when SOD existed in acquired pellicle and during adhesive process. When 2 strains were incubated with SOD, the nubers of S mutans Ingbritt were high and 6715 were significant low. Conclusion: Exogenous SOD promotes the growth of S mutans and influenced the numbers adhered to HA. |
