恒河猴胸腺的显微与超微结构观察

应用组织学、组织化学和透射电镜技术观察表明，恒河猴胸腺外包被膜，被膜结缔组织伸入其内部形成许多小隔，将胸腺实质分成许多小叶，小叶又由皮质和髓质组成，大部分的髓质彼此相连，被膜和小叶间隔内含有较多的肥大细胞。皮质主要由幼稚T细胞和皮皮细胞构成，另有少量的巨噬细胞和肥大细胞等；皮人还可见典型的血－胸腺屏障。髓质主要由成熟T细胞和上皮细胞组成，另有较多的肥大细胞和少量的巨噬细胞、交错突细胞、B淋巴细胞、浆细胞、嗜酸性粒细胞、肌样细胞以及一些胸腺小体和胸腺小囊。

Microstructure and Ultrastructure of the Thymus of the Rhesus Monkey (Macaca mulatta )

The thymus of the rhesus monkey ( Macaca mulatta) was studied by histological, histochemical and transmission electron microscopic techniques. The results showed that it was surrounded by a capsule continuous with thin connective tissue septa that divided the organ into many lobules, each consisting of cortex and medulla, and most of the medullae connected with each other. There were many mast cells in the capsule and interlobular septa. The cortex mainly consisted of immature T lymphocytes, epithelial cells, some mast cells, and macrophages and, in addition, typical blood-thymus barrier. The medulla was mainly composed of mature T lymphocytes, epithelial cells, also some mast cells and a few macrophages, interdigitating cells, myroid cells, B lymphocytes, plasma cells, eosinophilic granulocytes, thymic corpuscles and thymic cysts.
