| 摘 要： | 目的观察大鼠直肠壁内淋巴管的分布和形态、结构特点，为探讨直肠癌淋巴道转移的机制，提供形态学依据。方法用半薄、超薄切片、光镜和电镜下观察大鼠淋巴管的微细分布。结果大鼠直肠壁的黏膜固有层深部可见毛细淋巴管，黏膜下层、肌层和浆膜层均有毛细淋巴管和淋巴管。结论直肠壁各层内均有毛细淋巴管，除黏膜层外，还存有淋巴管。

Fine distribution and morphologic feature of intramural lymphatics in rats' rectum |
| |
| Abstract: | Objective To observe the fine distribution and morphologic feature of the intramural lymphatics in rats' rectum and to provide the morphological evidence for studying the mechanism of lymphous metastasis of rectum carcinoma.Methods The intramural lymphatics of rectum in rats were studied by light and electron microscopy.Results There were capillarylymphatics in deep lamina propria of runica membrane in the wall of rats' rectum and there were capillary lymphatics and lymphatics in tela submucosa,and lymphatics muscularis mucosa and serosa.Conclusion There are capillary lymphatics and lymphatics in every layer of rectum but tunica mucosa without lymphatics. |
