用酶、免疫组织化学染色法，半薄、超薄切片光、电镜观察和淋巴管间接注射法等多种技术研究了兔和Ｗｉｓｔａｒ大鼠肝的起始淋巴管（毛细淋巴管），以明确肝起始淋巴管的分布和形态特征，并测量了有关数据，为研究肝淋巴生成机理提供必要的依据。结果发现，肝起始淋巴管仅存在于较大的门管区结缔组织内，而肝小叶内无起始淋巴管。起始淋巴管在门管区的出现率约为２５％；其最大平均直径兔为２２．６μｍ，鼠为２７．６μｍ；平均横截面积兔为２３２．４μｍ２，鼠为２６８．８μｍ２。起始淋巴管的数密度兔为２．９个／ｍｍ２，鼠为２．２个／ｍｍ２；体密度兔为０．０００９８，鼠为０．００１４。出现起始淋巴管的门管区最小面积兔为３．９ｍｍ２，鼠为２．８ｍｍ２。在兔和鼠肝的被膜内均未发现起始淋巴管和淋巴管。
The initial lymphatic vessels (lymphatic vessels) of the liver of rabbits and Wistar rats were studied with various techniques such as enzyme, immunohistochemical staining, semi-thin, ultra-thin sliced light, electron microscopy and indirect lymphatic injection to clarify The distribution and morphological features of the initial lymphatic vessels in the liver were measured and the relevant data were measured to provide the necessary basis for studying the mechanism of hepatic lymphangiogenesis. The results showed that the initial hepatic lymphatic vessels only exist in the larger portal area connective tissue, and no initial lymphatics in the hepatic lobules. The initial incidence of lymphatic vessels in the portal area was about 25%; its maximum mean diameter was 22.6μm for rabbits and 27.6μm for mice; the average cross-sectional area was 232.4μm2 for rabbits and 268.8μm2 for mice. The number of initial lymphathetic rabbits was 2.9 per mm2, and the number of mice was 2.2 per mm2. The body density was 0.00098 for rabbits and 0.0014 for mice. The minimum area of the portal area where the initiating lymphatics appeared was 3.9 mm2 and the mouse was 2.8 mm2. No initial lymphatic and lymphatic vessels were found in the tunica of rabbit and rat liver.
