A method for the intravital microscopic study of the tracheal mucosal microcirculation in the rabbit is described. A low tracheostomy is performed for ventilation, while a hole cut in the ventral portion of the trachea cranial to the tracheostomy is used for observations. The trachea is immobilized by a fixation device. Microscopic observations are made with a Leitz stereo microscope. The microvasculature of the rabbit tracheal mucosa is characterized by centripetally arranged arterioles which subdivide into a fairly sparse capillary network at the mucosal surface. The capillaries drain into venular networks at different levels of the mucosa and collect finally into circumferentially arranged veins which run mainly between the cartilages. For comparative purposes the microvasculature of the human tracheal mucosa has been analysed in clarified (Spalteholz) preparations. This investigation shows that the microvascular architecture is principally the same in the human and rabbit tracheal mucosa. There is, however, a much denser capillary network in the human tracheal mucosa.
本文描述了一种对家兔气管黏膜微循环进行活体显微镜研究的方法。行低位气管切开术用于通气，而在气管切开术上方气管腹侧部切开的孔用于观察。气管通过固定装置固定。使用Leitz体视显微镜进行显微镜观察。家兔气管黏膜的微血管系统的特征是小动脉向心排列，在黏膜表面分成相当稀疏的毛细血管网。毛细血管在黏膜的不同水平汇入静脉网，最终汇入主要在软骨之间走行的环形排列的静脉。为了进行比较，在透明（斯帕尔陶兹）标本中分析了人气管黏膜的微血管系统。这项研究表明，人和家兔气管黏膜的微血管结构基本相同。然而，人气管黏膜中的毛细血管网要密集得多。
