目的：在超微结构水平研究猪囊尾蚴石灰小体的形成和代谢。方法：透射电镜。结果：石灰小体的形成可分成两个阶段：细胞内形成阶段和细胞外代谢阶段。石灰小体是在一种细胞内形成的，我们称为成石灰小体细胞。在形成的早期，石灰小体以分泌颗粒的形式出现在细胞内。随着石灰小体的发育，小体呈珠粒和板层样。此时，成石灰小体细胞胀大且细胞器消失。最后，小体聚集成致密黑色背景的颗粒，而成石灰小体细胞的核和细胞器全部消失。在一个成熟的成石灰小体细胞内有１－３或１０－２０个石灰小体。然后，小体释放到实质组织，随着代谢的消耗逐渐呈同心圆样的板层结构和空泡结构。结论：石灰小体是在一种细胞内形成，在实质组织的代谢过程中被消耗。
OBJECTIVE: To study the formation and metabolism of lime cysticercus cellulosae at the ultrastructure level. Methods: Transmission electron microscopy. Results: The formation of lime bodies can be divided into two phases: the intracellular formation phase and the extracellular metabolic phase. Lime bodies are formed within a cell, which we call lime bodies. In the early stages of formation, lime bodies occur as secretory granules in the cells. With the development of lime body, the body was beads and lamella-like. At this point, as a large body of lime cells swell and organelles disappear. Finally, the bodies clustered in dense black background particles, and limestone cells and organelles all disappear. There are 1-3 or 10-20 lime bodies in a mature limestone cell. Then, the body is released to the parenchyma, with the consumption of metabolism gradually concentric-like lamellar structure and vacuolar structure. Conclusion: Lime bodies are formed within a cell and are consumed during the metabolism of parenchymal tissue.
