Abstract

By means of the multilayer graphic and plastic reconstruction methods using series of semithin sections, spatial tridimensional organization of the epithelial complexes and blood microcirculatory bed in the rat palatal salivary glands and the lacrimal gland of the human newborn have been studied. Since their ducts serve not only for discharging their secrete into the external medium, but also for accumulation (as collectors), the sublobular unit--adenomere should be referred to as a part of elementary level of organization of the epithelial complexes. The adenomere has in its composition a collecting centrally situating duct. However, while studying structure of the blood microcirculatory bed, it is found out that there is not any strict territorial correspondence between its functional units and structural units of the glandular epithelium. Nevertheless, giving a great importance to a tight syntopic connection of the collecting ducts of the adenomeres with the postcapillary venules (that belong to filtrating microvessels), these are sublobular units--adenomeres that are distinguished as structural-functional units in the glands.

摘要

通过使用一系列半薄切片的多层图形和塑性重建方法,对大鼠腭唾液腺和人类新生儿泪腺中上皮复合体和血液微循环床的空间三维组织进行了研究。由于它们的导管不仅用于将分泌物排入外部介质,还用于积累(作为收集器),小叶下单位——腺小叶应被视为上皮复合体组织基本水平的一部分。腺小叶的组成中有一条位于中央的收集导管。然而,在研究血液微循环床的结构时发现,其功能单位与腺上皮的结构单位之间不存在任何严格的区域对应关系。尽管如此,由于非常重视腺小叶收集导管与毛细血管后微静脉(属于滤过微血管)的紧密同位连接,这些小叶下单位——腺小叶被视为腺体中的结构功能单位。
