摘　　要：为观察豚鼠和兔气管淋巴管的分布特征及超微结构，本文应用淋巴管间接注射、光镜和电镜观察及计算机图像分析的方法进行了研究。结果表明，两种动物气管淋巴管结构、分布相似。粘膜层仅存在丰富的毛细淋巴管，粘膜下层、肌层、外膜层有毛细淋巴管和淋巴管分布。在320张组织切片中，淋巴管检出李豚鼠为36％；兔为23％（P＜0．01）。淋巴管的平均最大直径豚鼠为22．6±14．1μm（x±s）；兔为23．7±14．9μm（x±s）。体密度豚鼠为2．05±0．49μm3／μm3×10－3（x±Sx）；兔为1．29±0．40μm3／μm3×10－3（x±Sx）。截面密度豚鼠为5．89±1．20Ly／mm2（x±Sx）；兔为2．32±0．58Ly／mm2（x±Sx）。豚鼠气管淋巴管比兔的丰富。超微结构，毛细淋巴管的壁均由一层内皮细胞围成，基膜不完整或缺乏，无周细胞和孔窗。内皮细胞间连接形式可分为端端、重叠和嵌合连接。内皮细胞胞质内有大量囊泡。The distribution and uitrastructure of tracheal intramural lymphatic vessels in guinea - pig and rabbit were studied by interinjection of lymphatic vessels, light and electron microscope and a computer image analysis system. The distribution and ultrastructure of the both animals were similar. Rich lmphatic capillaries were found in mucosa. There were lymphatic capillaries and lymph vessels in submucosa, muscularis and adventitia. Present percentage of lymphatic vessels (guinea - pig 36% ; rabbit 23%; p<0. 01 ) was examined in 320 tissue sections. Maxium diamerer [guinea - pig 22. 6±14．1μm (x±s); rabbit: 23. 7±14. 9μm (x±s)] were measured by Olympus Hight microscopy fixed micrometer. Volume density [guinea-pig: 2. 05±0.49μm3/μm3×10-3 (x±Sx) ; rabbit: 1. 29±0. 40μm3/μm3 ×10-3 (x±Sx)] and number density [guinea - pig: 5. 89±1.20Ly/mm2 (x±Sx); rabbit: 2. 32±0.58Ly/mm2 (x±Sx)] were determinied by a computer image analysis system. The density of tracheal lymphatic vessels in guinea - pig was greater than that in rabbit. The wall of lymphatic capillaries were consisted by a single layer of endothliocytes. The besal lamina was incontinous or missing. There are no pericyte and pores.The endotheliccytes were joined each other by three types, the end - to - end, overlapping and interdigitating. There were large vesicles in endotheliocytes.
