对苏氏鲶鳃结构进行扫描和透射电镜观察。鲶鳃丝末端膨大呈杓状结构 ,每一鳃丝两侧具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。还探讨了鲶鳃丝和鳃小片特殊的结构与功能
Scanning and transmission electron microscopy observations of the gill structure of the catfish Suisu. Catfish gill filaments swollen tip-like structure, each gill filaments on both sides of a large number of pleated gilllets, adjacent gill filaments gilllets in close inlaid arrangement. Gill ram and gill rake surface distribution of many taste buds. Gill filaments respiratory surface epithelial cells thin, highly vascularized, the formation of respiratory surface uplift; non-respiratory surface by the micro-spine cells connected to each other, the gap with the secretory cell openings. Gill pieces from the monolayer or several layers of epithelial cells and the basement membrane separated by the columnar cells and the flange around the vascular cavity, chlorine cells are distributed in the base of the gill piece, and has an open mouth outside. The special structure and function of gill filaments and gills are also discussed
