Abstract

Hitherto undescribed catecholamine-containing neuronal perikarya (CCNP) were demonstrated in the white and grey matter of the rat cervical spinal cord. In the white matter they were mainly located in the dorsal part of the lateral funiculus; the number of CCNP in the left lateral funiculus was significantly higher than that in the right and they also extended further caudally. After colchicine treatment, a greater number of CCNP were visible on both sides, the left side again containing more CCNP than the right. In addition, CCNP in colchicine-treated animals were observed further caudally than in untreated animals. In contrast, no lateralization was apparent in the grey matter CCNP.

摘要

在大鼠颈脊髓的白质和灰质中发现了迄今未描述过的含儿茶酚胺神经元胞体（CCNP）。在白质中，它们主要位于外侧索的背侧部分；左侧外侧索中的CCNP数量明显高于右侧，并且它们在尾侧延伸得更远。秋水仙碱处理后，两侧可见更多的CCNP，左侧的CCNP数量再次多于右侧。此外，与未处理的动物相比，秋水仙碱处理的动物中CCNP在尾侧的分布更远。相比之下，灰质中的CCNP没有明显的左右侧化现象。
