摘要
应用卵白素-生物素-过氧化物酶复合物(avidin-biotin-peroxidase complex,ABC)免疫组织化学方法对家鸽(columbae livia domesticus)消化道生长抑素细胞的分布密度和形态学特点进行了观察。结果表明:生长抑素(somatostatin,简称SS)细胞主要分布于胃体及其以下部位,其中胃体部的分布密度最高,小肠各段的分布密度较低,且小肠各部位间差异不显著。而在食管和嗉囊中均未发现SS细胞。SS细胞的形态多样,主要有圆形、椭圆形和锥体形等。主要分布在上皮细胞基部、上皮细胞之间和腺泡上皮细胞之间。通过形态学观察认为:家鸽消化道生长抑素细胞的分布与其消化道各部位的功能有关。
The morphological features and relative frequency of Somatostatin secreting cells in the digestive tract of the columbae livia domesticus were investigated by avidin-biotin-peroxidase complex immunohistochemical methods.The somatostatin secreting cells were presented in somatostatin body and below.and the number of somatostatin body was the largest and a few were showed in intestine,There was no significant difference between the various parts of the small intestine.But the Somatostatin secreting cells were not founded in the esophagus and crop.The shape of Somatostatin secreting cells was diverse;there were round,ellipse,cone and so on.The cells are found in between epithelial cells,at the basal region of epithelial cell,between glandular epithelial cells.By the morphological observation,we consider that the distribution of somatostatin cells in the digestive tract is relevanted to the function of each part of digestive tract.
