The investigation has been performed in 118 serial sections of human embryos. The development of vascular bed in ganglia of the respiratory tube at early embryogenesis has been studied. The main attention has been paid to the formation of periganglial vascular bed. Loop-like and arc-shaped connections between the developing vessels and galglia and rearrangement of periganglial vascular bed during embryogenesis are described. Three stages in the development of blood supply to the ganglia of the respiratory tube are noted: I stage--avascular (embryos are 17-30 mm long); II stage--formation of periganglial vascular bed (embryos are 33-50 mm long); III stage--formation of intraganglial vascular bed (embryos are 55 mm long and more). Within I and II stages, reorganization phases in the vascular bed are described. A suggestion is made that the vascular factor of the development and differentiation of ganglial elements starts acting since the formation of periganglial vascular bed; before this, the mesenchima surrounding the neuronal plexus performs their trophic.
该研究在118个连续的人类胚胎切片上进行。对胚胎早期发育阶段呼吸管神经节中血管床的发育进行了研究。主要关注神经节周围血管床的形成。描述了发育中的血管与神经节之间的环状和弧形连接以及胚胎发生过程中神经节周围血管床的重排。注意到呼吸管神经节血液供应发育的三个阶段：I期——无血管期（胚胎长度为17 - 30毫米）；II期——神经节周围血管床形成期（胚胎长度为33 - 50毫米）；III期——神经节内血管床形成期（胚胎长度为55毫米及以上）。在I期和II期内，描述了血管床的重组阶段。有人提出，神经节成分发育和分化的血管因素自神经节周围血管床形成时开始起作用；在此之前，围绕神经丛的间充质发挥其营养作用。
