中文摘要:

      采用阿立新蓝过碘酸雪夫试剂染色法，研究了波纹唇鱼消化道黏液细胞的类型和分布规律。波纹唇鱼黏液细胞在消化道各部位均有分布，不同部位黏液细胞密度和类型均有差异。在靠近消化腔的部位分布Ⅱ型黏液细胞；在黏膜层基部多分布Ⅲ型和Ⅳ型黏液细胞。口咽腔、舌和食道部位主要分布Ⅱ型和Ⅳ型黏液细胞；小肠和直肠黏膜层顶部主要分布Ⅱ型和Ⅳ型黏液细胞，基部主要为Ⅲ型和Ⅳ型黏液细胞。

英文摘要:

      The types and distribution of mucous cells in the alimentary canal of Cheilinus undulates Rüppell were studied using the AB-PAS (Alcian blue and periodic acid Schiff's reagent) staining method. The mucous cells are distributed in every part of the alimentary canal of Cheilinus undulates Rüppell, however, the cell densities and cell types vary at different locations. Type Ⅱ mucous cells are mainly located near the gastrovascular cavity, while type Ⅲ and type Ⅳ mucous cells are mainly found in the bottom of the mucous layer. Buccopharyngeal cavity, tongue and esophagus mainly posesse type Ⅱ and type Ⅳ mucous cells. The top of protuberances in small intestine and recta is characterized by type Ⅱ and type Ⅳ mucous cells, and the bottom is characterized by type Ⅲ and type Ⅳ mucous cells.KEY WORDSCheilinus undulates RüppellDigestive tractMucous cellsTypes and distribution
