摘要
在肠卷石蜡切片上,应用Grimelius法对锡嘴雀消化道嗜银细胞的分布、密度、形态等方面进行了比较研究。结果显示:在食管和腺胃等消化部位均未发现嗜银细胞,在肠段处遍及该种内分泌细胞,其分布密度整体呈上升趋势,在直肠处出现密度极值,而在十二指肠处的分布密度最低。嗜银细胞主要分布于黏膜及腺泡上皮之间,有少量位于上皮细胞基部。嗜银细胞的形态具有多样性:主要有椭圆形、锥体形、梭形等。其中锥体形嗜银细胞突起伸向肠腔,以发挥其内分泌作用。根据其内分泌细胞的结构形态可以认为锡嘴雀消化道内的嗜银细胞兼具内分泌与外分泌2种功能。
Based on the paraffin sections in the intestine,distribution,density,shape other aspects in argentaffine cells in digestive tract of Hawfinch were compared by using Grimelius method.Results are as follows： argentaffine cells couldn＇t be found in esophagus,proventriculus other digestive parts;the argentaffine cells could be found throughout most of the intestine;the argentaffine cells distribute in an upward trend;density maximum occurs in the rectum,in the duodenum density at the minimum.Argyrophil cells were mainly distributed in the epithelial cells of mucosa layer gastric gland,a few at the bottom of epithelial cells.Argyrophil cells are in the form of diversity： mainly oval,tapering,fusiform so on,among which tapering argentaffine cell extending to the gut lumen to play its role in endocrine.According to their structure morphology of endocrine cells,it is thought that argyrophil cells in the digestive tract of Hawfinch have functions of endocrine exocrine.
