By means of macro-microscopical preparation methods, horseradish peroxidase injection, semithin sections, electron microscopy histotopography and composition of microvessels of the sciatic nerve have been studied in 20 mature male white rats. The perineural membrane has been stated to have no its own vascular network. In composition of the sciatic nerve and its large branches muscular venules are revealed; they run longitudinally along the whole length of the endoneural space and are tributaries of the epineural veins. A suggestion is made that presence of the contractile apparatus in the venular wall can play an important role in formation of the postcapillary resistance, regulating the hydrostatic pressure value in the lumen of endoneural capillaries ad intensity of liquor filtration into the interstitial space.
通过宏观-微观制备方法，对20只成年雄性白色大鼠的坐骨神经微血管组成进行了辣根过氧化物酶注射、半薄切片、电子显微镜组织拓扑学研究。结果表明，神经束膜没有自身的血管网络。在坐骨神经及其大分支的组成中发现了肌性小静脉；它们沿神经内膜间隙的全长纵向走行，是神经外膜静脉的属支。有人提出，小静脉壁中收缩装置的存在可能在毛细血管后阻力的形成中起重要作用，调节神经内膜毛细血管腔内的静水压力值以及液体滤过到间质空间的强度。
