| 摘 要： | 对苏氏Mang鲶鳃结构进行扫描和透射电镜观察。Mang鲶鳃丝末端膨大呈杓状结构，每一鳃丝两侧具有许多呈褶状的鳃小片，相邻两鳃丝上的鳃小片紧密镶嵌排列。鳃弓和鳃耙表面分布众多味蕾。鳃丝呼吸面上皮细胞薄，高度血管化，形成呼吸面隆起，非呼吸面由微脊细胞彼此相连，间缝具分泌细胞开口。鳃小片由单层或数层外上皮细胞和由基膜相隔的柱状细胞及其围在血管腔的凸缘构成，氯细胞多分布在鳃小片基部，并有开口通外，还探讨了Mang鲶鳃丝和鳃小片特殊的结构与功能。

| Abstract: | The f ine structure of the gill in Pangasius sutchi has been investigated using transmission and scanning
electron microscopy. The terminal of gill filament of Pangasius sutchi expands to be spoon-shaped. Many
secondary gill lamellae arrange on two sides of each f ilament, and inlay each other. There are many taste buds
distributing on the surface of gill arches and gill rakers. The respiratory surface of gill f ilament is rough and
highly full of bloodvessels; the non-respiratory surface of gill f ilament is composed of tetragonal or hexagonal
epithelial cells, which form various patterns. There are many holes among the circular ridgy patterns. The basic
structure of the secondary lamellae consists of one or two outer epithelial layers, an intermediate basement
membrane layer internal to which are the pillar cells and their f langes which line the blood channels. The chloride
cells are frequently found in the base regions of the secondary lamellae and are overlain by a single epithelial
layer , they often seemed to be open at the surface between adjacent epithelial cells. The relationships between the
special structure of f ish gills and their funct ion are discussed. |
