利用兔耳内透明的护城河小室，通过直接显微镜观察，研究了新生毛细血管和新生毛细血管的通透性，并与陈旧毛细血管进行了比较。这些研究表明，在这样的小室中，静脉注射的蓝色染料T-1824更快地穿过毛细血管萌芽和新形成的毛细血管的壁，而不是穿过旧的毛细血管的壁。因此，毛细血管内皮细胞的通透性随年龄的变化而变化，新近形成的内皮细胞通透性更强。
The permeability of blood capillary sprouts and newly formed blood capillaries, as compared to that of older blood capillaries, was studied by direct microscopic observation, using transparent moat chambers in rabbits'' ears. These studies show that in such chambers the blue dye T-1824, injected intravenously, passes more rapidly through the walls of blood capillary sprouts and newly formed blood capillaries than through the walls of older blood capillaries. Thus the permeability of blood capillary endothelium was found to vary with age, the more recently formed endothelium being more permeable.
