The histomorphological investigations carried out on the ultimobranchial body of the Teleost Anoptichthys jordani Hubbs and Innes have enabled us to establish that it is an epithelial multifollicular body which lies within the transverse septum, beneath the musculature of the oesophagus and caudal to the Sinus venosus. Its parenchyma is surrounded by an extensive nerve network revealed by the Bodian silver technique. This nerve network and the occurrence of MAO activity in the ultimobranchial tissue indicate that it possesses a sympathetic innervation. The follicular epithelium sometimes acquire a pseudostratified condition in some follicles and sometimes in multistratified in others. In this latter case the presence of two main types of cell was noticed (light cells and dark cells). In these cells by the fluorescence microscopic analysis was revealed an intensely green fluorescence due to the presence of an aromatic monoamine, dopamine. This conclusion was further confirmed by the agreement between the argyrophilic cells and the fluorescent cells after silver staining. The possible partecipation of dopamine in the elaboration of polypeptide factor (calcitonin) is suggested. A notable analogy from the structural point of view to the calcitonin-producing cells of higher Vertebrates is also confirmed by the markedly argyrophilia of the main cells.
对盲眼鱼（Anoptichthys jordani Hubbs and Innes）鳃后体进行的组织形态学研究使我们能够确定，它是一个上皮性多滤泡体，位于横隔内，食管肌肉组织下方，静脉窦后方。其实质被博迪安银染技术显示的广泛神经网络所包围。该神经网络以及鳃后体组织中MAO活性的存在表明它具有交感神经支配。滤泡上皮在一些滤泡中有时呈假复层状态，在另一些滤泡中有时呈复层状态。在后一种情况下，注意到有两种主要类型的细胞（亮细胞和暗细胞）。通过荧光显微镜分析发现，这些细胞由于存在芳香单胺多巴胺而呈现强烈的绿色荧光。银染后嗜银细胞与荧光细胞的一致性进一步证实了这一结论。有人提出多巴胺可能参与多肽因子（降钙素）的合成。主细胞明显的嗜银性也从结构角度证实了与高等脊椎动物产生降钙素细胞的显著相似性。
