Abstract

: Catecholamines (CA) are known to play an important role in the physiology of most invertebrates. Here we provide the results on catecholaminergic systems study of two annelid species: Pygospio elegans (Spionidae) and Platynereis dumerilii (Nereididae). The nervous system was studied with the histochemical method of monoamine condensation with glyoxylic acid in combination with confocal laser scanning microscopy. Both animals possess developed catecholaminergic systems with similar general organization. However, in P. dumerilii considerably fewer cells were detected. In both species, CA-positive cells were found in the brain, ventral nerve cord as well as in the stomatogastric system, body wall, palps, prostomium, and regions around the chaetae. According to the cell morphology and their location in the most agile parts of

线虫和鸭嘴兽儿茶酚胺能系统的组织

儿茶酚胺(CA)在大多数无脊椎动物的生理中起着重要作用。本文提供了两种环节动物——秀丽Pygospio elegans (Spionidae)和沙蚕Platynereis dumerilii (neididae)的儿茶酚胺系统研究结果。采用单胺与乙醛酸缩合的组织化学方法，结合激光共聚焦扫描显微镜对神经系统进行研究。这两种动物都具有发达的儿茶酚胺能系统，具有相似的总体组织。然而，在P. dumerilii中检测到的细胞要少得多。在这两个物种中，ca阳性细胞在大脑、腹侧神经索以及口胃系统、体壁、触须、口口和毛囊周围区域都被发现。根据细胞形态和它们在最灵活部位的位置

期刊介绍： Scientific peer-reviewed journal INVERTEBRATE ZOOLOGY publishes original papers, reviews and brief communications on morphology, anatomy, embryology, taxonomy, phylogeny, and ecology of any group of invertebrates from protistans to lower chordates. INVERTEBRATE ZOOLOGY accepts manuscripts in English or Russian and publishes them in printed and electronic versions. The Russian translations of English titles, abstracts and figure captions of the papers written by non-Russian authors can be provided by the editors. Invertebrate Zoology invites authors to publish extended monographic manuscripts after usual reviewing procedure. The monographic manuscripts can include up to 400 thousand letters and be prepared in English or in Russian. Accepted monographic manuscripts will have priority to be published in the nearest issue of the journal.
