摘要 该文应用光镜、电镜和细胞计数技术对胚胎发育期虎斑颈槽蛇胸腺的发育分化进行了研究。在胚胎发育11期,胸腺原基内出现前淋巴细胞。从胚胎发育12期至出生前(16期),淋巴细胞不断增殖分化,小淋巴细胞逐渐增多,而淋巴母细胞和中淋巴细胞逐渐减少。胸腺皮质和髓质形成于16期。巨噬细胞以及肌样细胞和胸腺APUD细胞分别形成于胚胎发育14期和15期,随后数量有所增加,分别分布于胸腺皮质和髓质。 The embryonic development of thymus in snake ( Rhabdophis tigrina ) was investigated with light and electron microscopy, as well as cell account and immunohistochemical methods.The pro lyphoid cells located in thymus at stage 11. From stage 12 to birth time(stage 16) the miotics and development of lymphoid cells progressed, the number of small lymphocytes decreased.The thymic cortex and medulla developed completely at stage 16. Macrophage appeared at stage 14, while myoid cells and thymic APUD cells located in thymic medulla at stage 15 and their numbers slightly increased at stage 16.
