Abstract

I. The findings of seminiferous tubules after total curettage of the testicular parenchyme confirm the previous studies of the author on the origin of regenerates whose source are the cells of the walls of the seminiferous tubules, that are parts of the Moskoff's islets in the tunica albuginea. 2. In the 7th month after operation, in the first place the interstitial components of the parenchyme are substituted. The submicroscopical finding shows hyperplasia of interstitial cells from undifferentiated stages, through modified fibroblasts up to the adult Leydig cell. 3. The findings in the 10th month after operation confirm the regeneration of the seminiferous tubules in which Sertoli cells and spermatogonias are present. No higher stages of germinal cells were observed. A pecularity of the submicroscopical picture at that time is the reduplication of the lamellar layer of the tubular wall with a great number of foldings. In the interstitium Leyding cells were observed.

摘要

一、睾丸实质完全刮除后曲细精管的研究结果证实了作者先前关于再生起源的研究,其来源是曲细精管壁的细胞,这些细胞是白膜中莫斯科夫岛的一部分。2. 术后第7个月,首先是实质的间质成分被替代。亚显微镜观察结果显示,间质细胞从未分化阶段开始增生,经过形态改变的成纤维细胞,直至成年型睾丸间质细胞。3. 术后第10个月的研究结果证实了曲细精管的再生,其中存在支持细胞和精原细胞。未观察到生殖细胞的更高阶段。此时亚显微镜图像的一个特点是管壁板层的重复,伴有大量褶皱。在间质中观察到了睾丸间质细胞。
