A histochemical investigation was carried out to detect glycoproteins in the epithelium of the small and large intestine, ceca and cloaca (coprodeum) of Columba livia. The results showed that the goblet cells of both crypts and villi of the various segments studied presented neutral and acid glycoproteins. Acid glycoproteins include sulphoglycoproteins and sialoglycoproteins with predominance of the sulphated components, particularly in the large intestine, ceca and coprodeum. In the striated border neutral glycoproteins were the predominant components in an inner wide band and the acid in a superficial pellicle.
对家鸽小肠、大肠、盲肠和泄殖腔（粪道）上皮中的糖蛋白进行了组织化学研究。结果表明，在所研究的各个肠段的隐窝和绒毛中的杯状细胞均呈现中性和酸性糖蛋白。酸性糖蛋白包括硫酸糖蛋白和唾液酸糖蛋白，其中硫酸化成分占优势，特别是在大肠、盲肠和粪道中。在纹状缘，中性糖蛋白是内侧宽带中的主要成分，而酸性糖蛋白是表层薄膜中的主要成分。
