本文采用辣根过氧化物酶标记伴刀豆球蛋白A(Con A-HRP)法来研究人和犬、大小鼠消化管各段Con A受体的分布。结果表明:各段消化管粘膜上皮细胞都具有不同程度的阳性反应。除胃粘膜上皮细胞的核上区为阴性外,其他各段均以核上区反应最强。杯状细胞除人和犬的小肠及大小鼠的大肠阴性反应外,均有程度不等的阳性反应。胃底腺内壁细胞和主细胞的反应有明显的种系差异,人和犬二种细胞都为阳性反应,而大小鼠只有主细胞有阳性反应。肠腺阳性反应。神经元有较强的反应。平滑肌有不同强度的反应,人、犬比大小鼠强。由此提示消化管是一个高度异质性的细胞群体,并有种系差异。
In this paper, Con A-HRP method was used to study the distribution of Con A receptors in the digestive tract of human and canine, rat and mouse. The results showed that the digestive tract mucosal epithelial cells in all stages had different degrees of positive reaction. In addition to gastric mucosal epithelial cells in the nuclear area is negative, the other sections are the strongest nuclear reaction area. Goblet cells in addition to human and canine small intestine and large-mouse negative reaction of the large intestine, there are varying degrees of positive reactions. Stomach gland wall cells and the reaction of the main cells have obvious differences in germline, both human and canine cells are positive, while the size of the main mouse only positive reaction. Intestinal gland positive reaction. Neurons have a strong response. Smooth muscle has different strength of the reaction, human, dog stronger than the size of mice. This suggests that the digestive tract is a highly heterogeneous cell population and has germ line differences.
