Lungs of the human fetuses have been investigated at the age of 11, 18, 22 and 25 weeks. General histological staining methods and silver nitrate impregnation of the sections after Grimelius have been applied. Single argyrophile endocrinic cells (apudocytes) are revealed in the fetal lungs during all the time investigated. Groups of the argyrophilic cells--neuroepithelial bodies (NEB)--appear later and in small quantity. The quantity of the apudocytes and NEB gradually increases, especially noticeably in the distal parts of the bronchial tree. The number of the apudocytes increases during the canalicular stage of the pulmonary development. The endocrinic apparatus of the human lungs is forming in connection with development of the airy pathways, respiratory part and intraorganic vascular system.
对11、18、22和25周龄的人类胎儿肺部进行了研究。应用了常规组织学染色方法以及格里梅利乌斯法对切片进行硝酸银浸染。在整个研究期间，胎儿肺部均发现有单个嗜银内分泌细胞（亲银细胞）。嗜银细胞群——神经上皮小体（NEB）——出现较晚且数量较少。亲银细胞和NEB的数量逐渐增加，在支气管树的远端部分尤其明显。在肺发育的小管期，亲银细胞数量增加。人类肺部的内分泌器官是与气道、呼吸部分和器官内血管系统的发育相关联而形成的。
