| 摘 要： | 为了满足临床病理诊断及科研的需要，克服电镜原位细胞或组织包埋法之不足，作者研究出一种改良的透射电子显微镜细胞或组织原位简便快速包埋法。其特点是：①操作简便，全部包埋步骤（固定、脱水、浸泡及包埋）均在同一载体（培养瓶或显微镜观察的组织切片）上进行，能保存原位组织或细胞的超微结构；②快速，从固定到制备成超薄切片全过程仅需５小时；③易从载体上将包埋片分离下来，分离下来的包埋片完整，超微结构清晰。该方法不仅可用于单层培养细胞的超微结构研究，也可用于超微结构病理诊断，电镜免疫组织化学等方面的研究。文内还对该方法的操作要点进行了讨论。

| Abstract: | A simple and rapid method of preparing cell or tissue embedded in situ for transmission electron microscopy (TEM) is recommended. It is very simple; all procedures, including fixation, dehydration, infiltration and embedding, are performed on the same carrier (cultrue vase or microscopic slides). It is also very rapid; the whole process takes only five hours. The entire cell or tissue embedded in situ is easily separated from the carrier. The ultrastructures of the cell or tissue embedded in situ are well preserved with minimal damage. This method can be used in preparing cultured monolayer cell for TEM study, paraffin section for electron microscopic diagnosis, and frozen section for TEM immunohistochemistry or enzymehistochemistry. The main points of the procedures of preparation have been discussed. |
