Histological investigations were carried out on the sympathetic trunks of fourteen healthy, mature male and female coypu specimens of standard race, aged 8-24 months. The histological preparations impregnated using Bielschowski and Gross's method were prepared from front cervical, mid-cervical (central cervical), and pectoral-cervical ganglia as well as from pectoral, lumbar and sacral ganglia. An entire range of nerve cells displaying a certain type and degree of change was found in the above mentioned sympathetic ganglia. These cells are classified in the following order: cells with protoplasmic argyrophilia, cells with vacuole formations, with hyperplasia or hypertrophia of the processes, neuronophagic cells and degenerating cells.
对14只年龄在8至24个月的标准品种健康成熟的雄性和雌性河狸鼠的交感干进行了组织学研究。使用 Bielschowski 和 Gross 方法浸渍的组织学标本取自颈前、颈中（颈中央）、胸颈神经节以及胸、腰和骶神经节。在上述交感神经节中发现了一系列呈现出一定类型和程度变化的神经细胞。这些细胞按以下顺序分类：原生质嗜银细胞、有空泡形成的细胞、突起增生或肥大的细胞、噬神经元细胞和退化细胞。
