作者用血管内注入追示剂的方法研究机体各器官的屏障。经肉眼、光镜和电镜观察,初步证明,家兔的子宫存在着屏障。关于这一屏障结构的组成,作者认为:①子宫壁的平滑肌层和子宫内膜的固有层,平滑肌层则是主要的。此层除了平滑肌的小泡吞噬追示剂以外,巨噬细胞成群存在或成堆存在。巨噬细胞的胞质内吞噬了大量追示剂。这一现象表明,追示剂在 The authors use the method of intravascular injection of chaser to study the various organs of the body barrier. The naked eye, light and electron microscopy, initially proved that there is a barrier in the rabbit’s uterus. On the composition of the barrier structure, the authors believe: ① uterine wall and endometrial lamina propria, smooth muscle layer is the main. In addition to this layer of smooth muscle vesicles phagocytosis reminders, macrophages exist in groups or piles. Macrophage cytoplasm swallowed a large number of chaser agent. This phenomenon shows that the chase agent in
