| 摘 要： | 目的：观察放线共生放线杆菌对人牙龈成纤维细胞超微结构的影响。方法：１００ｍｇ／Ｌ细菌表面相关物质和人牙龈成纤维细胞在ＣＯ２孵箱内培养７２ｈ后，采用透射电镜观察细菌表面相关物质对成纤维细胞超微结构的影响。结果：主要使细胞粗面内质网扩张，线粒体水肿，溶酶体增多，但未见膜性结构有明显破坏现象。结论：此物质可影响细胞的超微结构，但不致细胞死亡

| Abstract: | Objective: To investigate the effects of surface associated material(SAM) of Actinobacillus actinomycetemcomitans (A.a) on the ultrastructure of human gingival fibroblasts(HGFs). Method:HGFs were exposed to 100 mg/L of SAM in a conventional culture for 72 hours, then the ultrastructure of the cells were observed under transmission electron microscope(TEM). Result:Dilated rough endoplasmic reticulum, distended mitochondria and increased lysosome were observed, while no obvious damage of membrane structure was found. Conclusion: SAM at the concentration of 100 mg/L may cause ultrastructure changes of HGFs rather than cell death. |
