Abstract

The effects of temporary ligation of the testicular artery have been analysed in rats with respect to Sertoli cells and multinucleated spermatogenic cells. The first cells to show ultrastructural changes are the Sertoli cells which progressively degenerate, leading to complete necrosis as the duration of ligation and post-ligation survival interval increases. The degree of degeneration of spermatogenic cells depends on the severity of Sertoli cell destruction. Temporary ligation of the testicular artery causes the formation of various types of multinucleated spermatogenic cells in the seminiferous epithelium. The mechanisms involved in the multinucleate formation are cell fusion, karyokinesis devoid of cytokinesis and phagocytosis. The variety of noxious agents causing formation of multinucleated spermatogenic cells in the seminiferous tubules of a number of species including man implies that the occurrence of multinucleated spermatogenic cells is not a specific response of the testis to a particular type of agent.

摘要

已针对支持细胞和多核生精细胞，分析了大鼠睾丸动脉临时结扎的影响。最早出现超微结构变化的细胞是支持细胞，随着结扎持续时间和结扎后存活间隔的增加，支持细胞会逐渐退化，最终完全坏死。生精细胞的退化程度取决于支持细胞破坏的严重程度。睾丸动脉临时结扎会导致生精上皮中形成各种类型的多核生精细胞。多核形成所涉及的机制包括细胞融合、无胞质分裂的核分裂和吞噬作用。在包括人类在内的许多物种的生精小管中，多种有害物质都会导致多核生精细胞的形成，这表明多核生精细胞的出现并非睾丸对特定类型物质的特异性反应。
