The complex carbohydrates in the camel duodenal glands were examined histochemically at light and electron microscopic levels. The duodenal glands of the camel were distributed in the submucosa 2 m caudal from the pylorus. These were branched tubuloalveolar glands. The terminal portion of each lobule was formed by only one type of mucous cell. The duodenal gland cells contained acidic and neutral carbohydrates. The mucous cells mainly contained sulfate and carboxyl carbohydrate with sialic acid, and they also contained a few neutral carbohydrates with different saccharide residues such as mannose, glucose, galactose, N-acetyl glucosamine and N-acetyl galactosamine. The results showed that the secretary granules of the duodenal glands in the camel contain mainly acidic carbohydrates. These findings seem to be the morphological characteristics of the duodenal glands in the camel.
在光学和电子显微镜水平上，对骆驼十二指肠腺中的复合碳水化合物进行了组织化学检查。骆驼的十二指肠腺分布在幽门后方2米处的黏膜下层。这些是分支管状泡状腺。每个小叶的末端部分仅由一种黏液细胞形成。十二指肠腺细胞含有酸性和中性碳水化合物。黏液细胞主要含有带唾液酸的硫酸盐和羧基碳水化合物，它们还含有一些带有不同糖残基的中性碳水化合物，如甘露糖、葡萄糖、半乳糖、N-乙酰葡糖胺和N-乙酰半乳糖胺。结果表明，骆驼十二指肠腺的分泌颗粒主要含有酸性碳水化合物。这些发现似乎是骆驼十二指肠腺的形态学特征。
