用凝集素亲和细胞化学ABC法比较分析了63例7～38周人胚胎升结肠和降结肠粘膜凝集素受体的定位分布.发现升结肠粘膜能表达刀豆素A受体和大豆素受体,降结肠粘膜能表达刀豆素体、大豆素受体和荆豆素-1受体,且升结肠和降结肠的刀豆素A受体和大豆素受体存在量的差异,两段结肠粘膜均不表达麦胚凝集素受体.表明:在胚胎发育过程中,升结肠和降结肠粘膜的糖复合物既有一定的相似性,也存在质和量的差异.
The localization distribution of ascending colon and descending colon mucosal lectin receptors in 63 cases of human embryos from 7 to 38 weeks was compared and analyzed by lectin affinity cell chemistry ABC method, and it was found that ascending colon mucosa could express concanavalin A receptor and daidzin receptor Body, descending colon mucosa can express concanavalin, daidzin receptor and ursolicin-1 receptor, and concanavalin and descending colon concanavalin A receptor and the difference between the amount of daidzin receptors, two segments Colonic mucosa did not express wheat germ agglutinin receptor, indicating that during the process of embryonic development, ascending colon and descending colon mucosa of sugar complexes have some similarities, there are differences in quality and quantity.
