【摘要】 本实验对大鼠磨牙牙周韧带细胞结构的超微结构进行了较细致的观察。使用5%EDTA-2Na脱钙液对样本进行充分脱钙,常规电镜制片。观察到牙周韧带的细胞成份有:成纤维细胞、成骨细胞、成牙骨质细胞、破骨细胞、破牙骨质细胞、巨噬细胞、未分化间质细胞、组织细胞、上皮细胞等。结合各细胞成份的超微结构,对其功能进行了探讨。更多还原

【Abstract】 An observation of the ultrastructure of cellular elements in periodontium of rats wasmade.The tissue was prefixed with a mixed solution of 5% glutaraldehyde and 4% paraforma-ldehyde.Then fully decalcified in 5% disodium EDTA solution.After that,the tissue wasfollowed by the usual specimen preparation for transmission electron microscopy.The cellularelements observed were:fibroblasts,osteoblasts,cementoblasts,osteoclasts,cementoclasts,macrophages,undifferentiated mesenchymal cells,mast cells,epithelial cells and so on.According to its ultrastructure,a disscusion of the function of each cellular elements wasmade.更多还原
