The aim of the present study was to investigate the effect of gender on the distribution of pancreatic islets in native chicken. Ten adult male and ten adult female Isfahan native chickens were used in this experiment. Results showed a distinct sexual dimorphism in the native chicken pancreas which depends upon the various fractions of the pancreatic lobes, which were occupied by alpha, beta and mixed islets. In both sexes, the islets were more frequently found in the splenic and the third lobes, whereas they were more scarcely observed in the ventral and the dorsal lobes. In both sexes, there were no alpha islets in the dorsal and ventral pancreatic lobes. The mean percentage of beta islets in the third and splenic lobes were significantly greater in males than females (p < 0.05). However, the mean percentage of mixed islets in the third and splenic lobes were significantly greater in females than males (p < 0.05). The mean percentage of the alpha islets in the splenic and third lobes and the mean percentage of beta and mixed islets in the dorsal and ventral lobes was similar in both sexes in chickens. There was no sex difference in the mean percentage of whole gland islets (p > 0.05).
本研究的目的是调查性别对本地鸡胰岛分布的影响。本实验使用了10只成年雄性和10只成年雌性伊斯法罕本地鸡。结果显示，本地鸡胰腺存在明显的性别二态性，这取决于胰腺叶的不同部分，这些部分被α、β和混合胰岛占据。在两性中，胰岛在脾叶和第三叶中出现的频率更高，而在腹侧叶和背侧叶中则较少观察到。在两性中，背侧和腹侧胰腺叶均无α胰岛。雄性第三叶和脾叶中β胰岛的平均百分比显著高于雌性（p < 0.05）。然而，雌性第三叶和脾叶中混合胰岛的平均百分比显著高于雄性（p < 0.05）。鸡的两性中，脾叶和第三叶中α胰岛的平均百分比以及背侧叶和腹侧叶中β胰岛和混合胰岛的平均百分比相似。全腺胰岛的平均百分比不存在性别差异（p > 0.05）。
