Abstract

The lumbar spinal cord of the rat was studied by combined retrograde fluorescent labelling with 4',6-diamidino-2-phenylindole-2HCl (DAPI) and immunoperoxidase procedure using serotonin antiserum. A peculiar small neuronal group endowed more densely than other anterior horn neurons with serotonin-like immunoreactive fibers was recognized in the anterior column of lumbar segments L1-L2. At the same time, this small nucleus was shown to contain the motoneurons innervating the cremaster muscle by means of retrograde labelling with DAPI. It is tentatively suggested that the bulbospinal descending serotonin system is particularly intimately connected with the function of the cremaster muscle.

摘要

采用4',6-二脒基-2-苯基吲哚-2盐酸盐（DAPI）逆行荧光标记与使用血清素抗血清的免疫过氧化物酶法相结合，对大鼠腰脊髓进行了研究。在腰段L1-L2的前柱中识别出一个特殊的小神经元群，其比其他前角神经元更密集地分布着血清素样免疫反应纤维。同时，通过DAPI逆行标记显示该小核包含支配提睾肌的运动神经元。初步认为延髓脊髓下行血清素系统与提睾肌的功能特别密切相关。
