肝深淋巴管的分布及其与肝浅淋巴管的交通

DISTRIBUTION OF HEPATIC DEEP LYMPHATICS AND THEIR COMMUNICATION WITH HEPATIC SUPERFICIAL LYMPHATICS

目的 :探讨肝浅淋巴管和深淋巴管的交通 ,以及肝淋巴管的交通在肝脏病理学方面的意义。材料和方法 :采用普鲁士蓝注射、厚片透明和组织切片的方法 ,在 52例小儿和 8例胎儿的肝脏对肝淋巴管作了形态学观察。结果 :肝深淋巴管包括小叶间淋巴管和小叶下淋巴管 ,分别位于门管区的疏松结缔组织和小叶下静脉的外膜内。星状浅淋巴管和少数区域淋巴管经肝表面的小凹或裂隙注入小叶间淋巴管。阻断肝深淋巴管时 ,注射剂经肝深淋巴管返流入肝浅淋巴管。结论 :肝浅淋巴管和肝深淋巴管之间存在着丰富的交通关系。当肝深淋巴管引流受阻时 。

Objective: To explore communication of hepatic superficial lymphatics and hepatic deep lymphatics and its pathological effects on hepatic diseases. Mothods: Hepatic lymphatics were observed on livers of 52 children and 8 fetuses with injection of Prussian blue, transparent thick slices and tissue slices. Results: Hepatic deep lymphatics consisted of interlobular lymphatics and sublobular lymphatics, which were located in loose connective tissues of portal areas and the adventitia of sublobular veins respectively. Star superficial lymphatics and a few regional superficial lymphatics communicated with interlobular lymphatics at foveae and cracks. When hepatic deep lymphatics were obstructed, the dye in hepatic deep lymphatics flowed into hepatic superficial lymphatics. Conclusion: There is rich communication of hepatic superficial lymphatics and hepatic deep lymphatics. When hepatic deep lymphatics are obstructed, the lymph of the liver may flow through hepatic deep lymphatics.
