摘　　要：用电镜观察了大鼠膈毛细淋巴管的超微结构.结果表明,内皮细胞较薄,无孔窗和周细胞,基底膜薄而不连续.内皮细胞间的连结有三种基本形式:重叠连结(53.2%)、端端连结(20.3%)和插入连结(12.5%).此外,还有变异的端侧连结及连结的对放状态(>30nm)(11%),伴粘着装置的连结占54%;.胞质内含有大量囊泡,其分布形式有:向腔面和非腔面开放,贴附于腔面和非腔面及游离于胞质中.囊泡分有衣囊泡和无衣囊泡.Ultrastructure of the lymphatic capillaries of the diaphragma in rat were studied with electron microscopy. Endothelial cells were found to be thin, non - fenestrated and lacking of pericytes and a continuous basal lamina. The endothelial cells were joined to each other in three basic types of intercellular junctions: overlapping type(53.2%), end-to-end type(20.3%) and interdigitating type (12.5%). In addition, there were some variant intercellular junctions, such as end - to - lateral type (3%), open junction(>30nm)(11%) and adherent type(5.4%). Large amounts of vesicles were present within the cytoplasma. The distribution of the vesicles was as follows: opened onto or touched the abluminal surfaces, opened onto or touched the luminal surfaces without visible connection to either surface. Vesicles was diveded into uncoated and coated vesicles.
