This study aims to provide a histological description of different regions of the gastric and duodenal mucosa in Rhesus monkey, as well as to analyze the distribution and the relative frequency of 5-HT. The cardia region mucosa consists of simple columnar epithelium PAS + and AB + and the 5-HT cells were observed at the base of the gland (QA [5-HT cells]/mm²) = 8.72 ± 4.98). The body region, has a smaller number of glands. The 5-HT cells were found predominant in the base of the gastric glands. QA= 6.96 ± 3.81. When compared to body region, the stomach fundus has smaller gastric pits. The 5-HT cells are found at the base of the glands near the main cells. QA = 5.29 ± 2.09. The pylorus region was found to have deep pits and well-developed gastric glands. The 5-HT cells are scarce, at the base of the pyloric gland. QA = 1.18 ± 1.36. The duodenum presented goblet cells strong PAS + and AB +. 5-HT cells were found both in the lining epithelium and in the intestinal glands. QA = 8.16 ± 2.59.

5HT在恒河猴（猕猴）的胃和十二指肠中的表达。

本研究旨在提供恒河猴胃和十二指肠粘膜不同区域的组织学描述，并分析5-HT的分布和相对频率。ia门区粘膜由简单的柱状上皮PAS +和AB +组成，在腺体底部观察到5-HT细胞（QA [5-HT细胞] /mm²）= 8.72±4.98。身体部位的腺体较少。发现5-HT细胞主要在胃腺的底部。QA ＝ 6.96±3.81。与身体部位相比，胃底的胃凹较小。5-HT细胞位于主要细胞附近腺体的底部。质量检查= 5.29±2.09。发现幽门区域有深凹坑和发达的胃腺。5-HT细胞在幽门腺底部稀少。QA = 1.18±1.36。十二指肠呈现杯状细胞强PAS +和AB +。在衬里上皮和肠腺中均发现了5-HT细胞。质量检查= 8.16±2.59。
