摘要
应用Grimelius银染法对黄雀(Carduelis spinus)消化道嗜银细胞的分布、密度、形态进行了研究。结果显示:食管和嗉囊中未发现嗜银细胞,消化道其他部位均有嗜银细胞,其分布密度大体呈波浪型,有两个分布高峰分别是腺胃和回肠,十二指肠分布密度最低。嗜银细胞主要分布于粘膜上皮之间和腺泡上皮之间,也有少量位于上皮细胞基部。嗜银细胞形态多样呈椭圆形、锥体形、梭形等,其中锥体形嗜银细胞突起伸向肠腔,梭形嗜银细胞两端均有突起,分别指向肠腔和固有膜。笔者还结合黄雀消化道嗜银细胞分布型的形成与各部位消化功能有关的特点进行了讨论,认为黄雀消化道内嗜银细胞具有内、外分泌两种功能。
Using the silver niterate method of grimelius to study the distributed density and morphology of cells in the digestive tract of Carduelis spinus.The results are as follows： the argentaffine cells could be found throughout most of the digestive tract, the argentaffine cells distribute wavelike, we couldn＇t find the argentaffine cells in esophagud and ingluvitis, there are two high peaks, they are stomach and ileum, duodenum distribute the density lowest. The argentaffine cells were seen between epithelial cells of mucosa layer and gastric gland, a few at the bottom of epithelial cells. The shape of argentaffine cells was diberse, there were ellipse, tapering, shuttle and so on. Tapering cells always had one long processus extending to the gut lumen, shuttle cells had two long processus, one extending to the gut lumen, the other extending to the lamina propria. This text still combined the characteristics that the argentaffine cells in digestive tract of Carduelis spinus maybe related to different digestive function of different region to carry on a discussion. Thinking that argentaffine cells in digestive tract of Carduelis spinus might have both exocrine and endocrine functions.
