The mucosal capillaries of the proximal intestine in a freshwater teleost (Prochilodus scrofa) are lined by an endothelial sheet with several fenestrated or pored domes, which are observed both in the thinner and thicker cytoplasmic extensions of the endothelium. These domes sometimes communicate between the inner and the outer side of the capillary wall, forming a transendothelial channel-like structure with internal diaphragms. The pored domes seem to be a frequent structure in fishes. Their ultrastructure in the proximal segment of the intestine, where the flow of substances through the endothelium is intense, is described.
淡水硬骨鱼（野结鱼）近端肠道的黏膜毛细血管由一层内皮细胞覆盖，内皮细胞有几个有孔的或带孔的穹顶，在内皮细胞较薄和较厚的细胞质延伸部分均能观察到。这些穹顶有时在毛细血管壁的内侧和外侧之间相通，形成一种带有内部隔膜的跨内皮通道样结构。有孔穹顶似乎是鱼类中常见的结构。本文描述了它们在肠道近端的超微结构，此处物质通过内皮的流动很强烈。
