本文用自然杀伤细胞(NK)功能缺陷的Beige小鼠6只,正常C_(57BL/6J)小鼠6只,C_(57BL/6J)裸鼠6只,比较观察了其淋巴结和胸腺的组织学特点。取各组小鼠腹腔淋巴结和胸腺、Bouin液固定、HE和Foot法染色,光镜观察。本实验发现,Beige小鼠淋巴结被膜明显增厚,内有成群胞质丰富的圆形细胞,胞核较小,居于中央。Foot法染色,可见这些细胞周围有网状纤维。被膜内有由矮立方形细胞围成的管道,腔内含液体,但未见淋巴细胞。关于被膜的这种结构特点,尚未见到类似的报道。淋巴结皮质浅层仅有少量致密淋巴组织,周围为密集的网状细胞,其间有少许
In this study, 6 Beige mice, 6 normal C57BL / 6J mice and 6 C57BL / 6J nude mice were used to study the histological features of lymph nodes and thymus Features. Peritoneal lymph nodes and thymus were taken from the mice in each group, fixed with Bouin solution, stained with HE and Foot, and observed with light microscope. The experiment found that Beige mice significantly thicken the lymph nodes, there are groups of cytoplasm rich round cells, smaller nuclei, living in the center. Foot staining, showing that these cells around the reticular fibers. Envelope surrounded by dwarf cubic cells, the lumen contains liquid, but no lymphocytes. There is no similar report on this structural feature of the envelope. Only a small amount of lymph node cortical shallow lymphoid tissue around the dense reticular cells, during which a little
