The nervous system of the mermithid nematode Romanomermis culicivorax was investigated at different developmental stages for the distribution of catecholamine(s). The catecholaminergic nervous system increased in complexity during development. In the adult nematode, catecholamine(s) occurred in the nerve ring and associated ganglia, cephalic nerves, ventral and dorsal nerve cords and mid-body region ganglia. The distribution of catecholaminergic ganglia in the tail region was different for each sex. The tail region of males contained 16-20 catecholaminergic ganglia, whereas the tail of females contained only 2 ganglia. The catecholamine widely distributed throughout the nervous system of R. culicivorax is not dopamine, since immunoreactivity to dopamine was observed only in the amphids. The results suggest that the catecholamine(s) is widely distributed within the nervous system of R. culicivorax and might function as a neurohormone or neurotransmitter in controlling physiological and developmental processes.
研究了食蚊罗索线虫在不同发育阶段儿茶酚胺的分布情况，以了解其神经系统。儿茶酚胺能神经系统在发育过程中复杂性增加。在成年线虫中，儿茶酚胺存在于神经环及相关神经节、头部神经、腹侧和背侧神经索以及身体中部区域神经节中。儿茶酚胺能神经节在尾部区域的分布因性别而异。雄性尾部区域含有16 - 20个儿茶酚胺能神经节，而雌性尾部仅含有2个神经节。食蚊罗索线虫整个神经系统中广泛分布的儿茶酚胺不是多巴胺，因为仅在头感器中观察到对多巴胺的免疫反应性。结果表明，儿茶酚胺在食蚊罗索线虫的神经系统中广泛分布，可能作为神经激素或神经递质来控制生理和发育过程。
