中文摘要：

[目的]该研究旨在探讨非洲雏鸵鸟肠道各型杯状细胞的分布规律。[方法]采用阿利新蓝一过碘酸雪夫反应（AB／PAS）观察雏鸵鸟肠道杯状细胞的类型与分布。阿利新蓝（AB）将酸性黏多糖染为蓝色，雪夫试剂（PAS）将中性黏多糖染为红色。[结果]根据染色结果可将杯状细胞分为4种类型：Ⅰ型红色：PAS阳性，AB阴性Ⅱ型蓝色，AB阳性，PAS阴性；Ⅲ型紫红色，PAS阳性强于AB阳性，Ⅳ型蓝紫色，AB阳性强于PAs阳性。在雏鸵鸟肠道内，以Ⅲ型和Ⅳ型杯状细胞为主。十二指肠、空肠、回肠中杯状细胞数量逐渐减少，盲肠、结肠、直肠中杯状细胞数量逐渐增加。大肠中杯状细胞数量明显比小肠中要多，直肠是含杯状细胞数量最多的肠段。[结论]以上结果表明，各型杯状细胞的分布与肠道结构及功能密切相关，其分泌的黏液在机体消化与黏膜免疫方面都具有重要作用。

英文摘要：

[Objective] This study aimed to investigate the distribution law of different goblet cells in the intestinal tracts of African ostrich chicks. [Method] Alcian blue/pe- riodic acid-schiff reaction （AB/PAS） was adopted to observe and analyze the types and distribution of goblet cells in the intestinal tracts of ostrich chicks. Acid mu- copolysaccharide could be stained blue with alcian blue （AB）, and neutral mu- copolysaccharide could be stained red with periodic acid-schiff reagent （PAS）. [Result] According to AB/PAS results, goblet cells in the intestinal tracts were divided in- to four types： TypeⅠ was pure red, with AB negative result and PAS positive result containing neutral mucoitin; type Ⅱ was pure blue, with AB positive result and PAS negative result containing acidic mucoitin; type Ⅲ was purple reddish, with PAS posi- tive result greater than AB; typeⅣ was purple blue, with AB positive result greater than PAS. Large quantities of goblet cells were found in the intestinal tracts of os- trich chicks, mostly type III and IV.The quantities of goblet cells were decreased gradually in the duodenum, jejunum and ileum, while the quantities were increased in the cecum, colon and rectum. The goblet cells in the large intestine are more than that in the small intestine. The most quantities of goblet cells were contained in rectum. [Conclusion] These results indicate that the distribution of goblet cells is closely related with the structure and function of intestinal tracts. The mucus secret- ed by the goblet Cells plays a series of important roles in the digestion and mucosal immunization.
