Abstract

The distribution and relative frequency of gastrointestinal endocrine cells were investigated in the stomach and small intestine (duodenum and jejunum) of a lion (Panthera leo). The present study was an immunohistochemical investigation of endocrine cells showing immunoreactivity for serotonin, gastrin, or cholecystokinin (CCK). Serotonin-immunoreactive (IR) cells were detected throughout the gastrointestinal tract with the highest frequency in the duodenum. Gastrin-IR cells were numerous in the pyloric region of the stomach and moderate numbers were also seen in the duodenum and jejunum. Moderate numbers of CCK-IR cells were only detected in the duodenum and jejunum.
