摘　　要：利用阿利新蓝和过碘酸雪夫试剂染色方法对鲫鱼(Carassius auratus)、鲢鱼(Hypophthalmichthysmolirtix)、鲇鱼(Silurus asotus)、中华蟾蜍(Bufo bufo gargarizans)、黑斑蛙(Rana nigromaculata)、中华鳖(Trionyx sinensis)和巴西彩龟(Trachemys scripta elegans)消化道黏液细胞进行了观察与分类,结果显示,AB-PAS染色后动物消化管黏液细胞表现为4个类型:Ⅰ型玫瑰红色;Ⅱ型蓝绿色;Ⅲ型紫红色;Ⅳ型蓝紫色。除鲫鱼和鲢鱼外,这些动物食管始部黏液细胞形态多样,表现为多种类型,食管中部杯状细胞密集排列,主要是Ⅱ型和Ⅳ型。除鲫鱼外各种动物胃体黏膜上皮细胞与胃腺颈部细胞主要为Ⅰ型和Ⅲ型,黏液颗粒集中在细胞的核上区。胃腺黏液细胞着色淡,鲇鱼、黑斑蛙、中华鲢与巴西彩龟为Ⅰ型和Ⅲ型,中华蟾蜍为Ⅲ型和Ⅳ型。中华鳖、巴西彩龟、鲇鱼、黑斑蛙、中华蟾蜍小肠和鲢鱼肠各部的杯状细胞主要为Ⅲ型和Ⅳ型,鲫鱼肠各部和中华鳖、巴西彩龟、鲇鱼、黑斑蛙、中华蟾蜍大肠的杯状细胞主要为Ⅱ型和Ⅳ型。The type and distribution of mucous cells in digestive tract of Carassius auratus, Hypophthalmichthys molirtix, Silurus asotus , Bufo bufo gargarizans , Rana nigronmaulata , Trachemys scripta elegans and Trionyx sinensis are studied by using the AB-PAS staining. There are four types of mucous cells observed, type Ⅰ in rose-red colour, type Ⅱ in green, type Ⅲ in purplish-red,and type IV in purplish-blue.These four types of cells are located in the forepart of oesophagus, except in C. auratus and H. molirtix. Whereas, the goblet cells, which mainly belong to type Ⅱ and Ⅳ , are arranged closely in the middle and last part of oesophagus. The mucosal epithelium and mucous neck cells of fundic gland in stomach mainly contain type Ⅲ and type Ⅰ cells, in which the mucous granules are concentrated in their shallow part, except in C. auratus. The mucous cells of stomach gland of H. molirtix, R. nigromaculata, T. scripta elegans and Trionyx sinensis mainly belong to types Ⅲ and Ⅰ, but the cells of B. b. gargarizans mainly belong to types Ⅲ and Ⅳ , with slightly staining. The goblet cells of intestinum tenue of S. asotus, B. b. gargarizans , R. nigronmaulata , Trachemys scripta elegans , Trionyx sinensis and cells in all parts of intestinum of H. molirtix mainly belong to types Ⅲ and Ⅳ , and the goblet cells in all parts intestinum of C. auratus and in intestinum crassum of S. asotus, B. b. gargarizans, R. nigromaulata, Trachemys scripta elegans, Trionyx sinensis mainly belong to types Ⅱ and Ⅳ .
