Abstract:The pancreas is an important digestive organ. Previous anatomical and histological studies on porcine pancreas mainly focused on the distribution of blood vessels and ducts. In this research, 24 control animals in another experiment were used to observe and measure the histo-morphological data of the pancreas of Bama minipigs. The result showed that the pancreas morphology of Bama minipigs is quite different. As a whole, the gross structure can be divided into 3 lobes, namely, spleen lobe, duodenal lobe and connecting lobe. According to the size, it can be divided into 3 types: the standard type, the thin type and the thick type ( among the 24 pigs, 3 types account for 16 / 24, 6 / 24 and 2 / 24, respectively) . The relative weight of pancreas accounts for 0. 09% to 0. 15% of body weight. The islets of Bama minipigs are generally small, and most of them are ultra-small type which compose of endocrine cell clusters. The relative weight of islets account for 1. 52% to 4. 98% of the pancreas and β cells account for 0. 012% to 0. 024% of body mass.

摘要:胰腺是重要的消化器官。 以往关于猪胰腺的解剖组织学研究,主要侧重于血管和导管的分布。 本研究利用本课题和其他课题中的 24 头对照组动物,观察和测定巴马小型猪胰腺的组织形态学数据。 结果表明:巴马小型猪的胰腺形态变异较大,大体结构可分为 3 个叶,即脾叶、十二指肠叶和连接叶;初步分为 3 种类型,即标准型、纤细型和粗壮型;24 头猪中,3 种类型分别占比 16 / 24、6 / 24 和 2 / 24。 胰腺占比体质量的 0. 09% ~ 0. 15%。 巴马小型猪的胰岛普遍较小,以超小胰岛居多。 胰岛占比胰腺的 1. 52% ~ 4. 98%。 胰岛 β 细胞占比体质量的 0. 012‰ ~ 0. 024‰。
