| 摘要: |
| 运用H.E.染色法和SP 免疫组织化学技术, 观察了褶纹冠蚌(Cristaria plicata(Leach)中枢神经系统脏神经节的谷氨酸(glutamate, Glu)、γ-氨基丁酸(γ-aminobutyric acid, GABA)、多巴胺(dopamine, DA)、乙酰胆碱(acetylcholine, Ach)和5-羟色胺(5-hydroxytryptamine, 5-HT)神经元的分布和形态。Glu 神经元、GABA神经元和DA神经元多为小型细胞, Ach 神经元多为中型细胞, 5-HT 神经元多为大、中型细胞, 偶见小型细胞。并且DA 神经元分布在脏神经节的整个胞体区, Ach 神经元多分布于近外套神经和鳃神经根部, 而在中央纤维网区域存在大量GABA 能神经纤维。结果表明, 褶纹冠蚌脏神经节内含有Glu、GABA、DA、Ach 和5-HT 能神经元, 但这5 种神经元的形态和分布有所不同。 |

| Distribution of glutamatergic, GABAergic, dopaminergic, acetycholinergic and serotonergic neurons in the visceral ganglion of the bivalve Cristaria plicata |

| Abstract: |
| The distribution and morphology of glutamate-, GABA-, dopamine- acetycholine- and serotone-containing neurons in the visceral ganglion of the bivalve Cristaria plicata were observed by Hematoxylin-Eosin staining method and SP immunohistochemical technique. The cellular layer of the visceral ganglion had glutamatergic, GABAergic and dopaminergic neurons in small size and acetycholinergic neurons in medium size, and most of serotonergic neurons were in large cell bodies. Moreover, dopaminergic neurons were widely distributed in the whole cortex of the ganglion, whereas acetycholinergic neurons were mainly localized near the pallial nerves and the roots of branchial nerves. GABAergic fibers could be seen in the central neuropil. The present results indicate that the visceral ganglion in the visceral ganglion of the Cristaria plicata contains glutamatergic, GABAergic, dopaminergic, acetycholinergic and serotonergic neurons with different quantities and densities. |
