The regional distribution and relative frequency of endocrine cells in the gastrointestinal tract of the camel, Camelus bactrianus, were investigated using immunohistochemical methods. Ten types of immunoreactive (IR) endocrine cells were identified in this study. Among these cell types, only serotonin- and somatostatin-IR cells were detected in almost all regions of the gastrointestinal tract. Most of the cell types showed peak density in the pyloric gland region. The others showed restricted distribution: gastrin, cholecystokinin (CCK), motilin, bovine pancreatic polypeptide (BPP), and (gastric) substance P in the stomach; gastrin, CCK, BPP, gastric inhibitory polypeptide (GIP), glucagon, peptide tyrosine tyrosine (PYY) and substance P in the small intestine; and CCK, motilin, BPP, and PYY in the large intestine. Fundamentally the distribution pattern of endocrine cells in the gastrointestinal tract of the camel is similar to that of cattle. The distribution and frequency of endocrine cells in the glandular sac region are the same as those of the cardiac gland.
采用免疫组织化学方法，对双峰驼胃肠道内分泌细胞的区域分布及相对频率进行了研究。本研究鉴定出10种免疫反应性（IR）内分泌细胞。在这些细胞类型中，几乎在胃肠道的所有区域均检测到了5-羟色胺和生长抑素免疫反应性细胞。大多数细胞类型在幽门腺区域密度最高。其他细胞则分布受限：胃泌素、胆囊收缩素（CCK）、胃动素、牛胰多肽（BPP）和（胃）P物质分布于胃中；胃泌素、CCK、BPP、胃抑制多肽（GIP）、胰高血糖素、肽YY（PYY）和P物质分布于小肠中；CCK、胃动素、BPP和PYY分布于大肠中。从根本上讲，骆驼胃肠道内分泌细胞的分布模式与牛相似。腺囊区域内分泌细胞的分布和频率与贲门腺相同。
