Immunocytochemical methods were employed to demonstrate endocrine cells, containing peptides and serotonin, in the gut of the impala. Cells immunoreactive to serotonin, somatostatin, gastrin, cholecystokinin, glucagon, neurotensin, secretin, glucose-dependent insulinotropic peptide and motilin were detected. Antisera raised to substance P and pancreatic polypeptide failed to stain any cells. The distribution of these peptide-containing cells is more in line with the situation in sheep than other ruminants. In contrast, the distribution and abundance of serotonin cells in the gut of the impala parallels the situation seen in game herbivores.
采用免疫细胞化学方法在黑斑羚的肠道中显示含肽和5-羟色胺的内分泌细胞。检测到对5-羟色胺、生长抑素、胃泌素、胆囊收缩素、胰高血糖素、神经降压素、促胰液素、葡萄糖依赖性促胰岛素多肽和胃动素呈免疫反应的细胞。针对P物质和胰多肽产生的抗血清未能使任何细胞着色。这些含肽细胞的分布与绵羊的情况比其他反刍动物更为一致。相比之下，黑斑羚肠道中5-羟色胺细胞的分布和数量与食草性猎物的情况相似。
