本文观察到60/钴γ线800拉德全身照射后大鼠小肠亲银细胞和嗜银细胞同其它上皮细胞具有相似的损伤和修复过程。其中,十二指肠亲银细胞和嗜银细胞的数目,照后第2～3天比对照组显著减少(t>0.01),照后第5天显著增加(t>0.01)。肠腺的内分泌细胞损失较绒毛的少,恢复较绒毛的快。空、迴肠的变化和十二指肠相平行,但不如十二指肠明显,提示十二指肠内分泌细胞对辐射比空、迴肠更为敏感。 In this paper, it is observed that the small intestine-like cells and argyrophilic cells of rat 60 have similar damage and repair process with other epithelial cells. Among them, the number of duodenal pro-silver cells and argyrophilic cells was significantly decreased (t> 0.01) on the 2nd to 3rd days after irradiation, and significantly increased on the 5th day after irradiation (t> 0.01). The loss of endocrine cells in the gut gland is less than in the villus, and recovery is faster than in the villus. Empty, ileal changes parallel to the duodenum, but not as obvious duodenum, suggesting that duodenal endocrine cells more sensitive to radiation than empty, ileum.
