本文比较了老年大鼠(26～28月龄)、成年大鼠(3～5月龄)及幼鼠(生后21天)胃窦粘膜内Ec细胞的形态。实验分别取上述三个时期的大鼠胃窦粘膜,应用免疫组织化学PAP法特异地显示粘膜内5-羟色胺样内分泌细胞(Ec细胞)。在光镜下观察了Ec细胞的形态和分布,计数了单位面积内细胞数目,并用OPTON图像分析仪IBAS1系统测量了细胞面积。结果如下:1.老年大鼠和成年大鼠胃窦粘膜Ec细胞数量上无明显差异,但均高于幼
This article compared the morphology of EC cells in the antral mucosa of aged rats (26-28 months old), adult rats (3-5 months old) and young rats (21 days after birth). The gastric mucosa of the antral mucosa of rats in the above three periods were respectively taken for experiment. The mucosal serotonin-like endocrine cells (Ec cells) were specifically displayed by the immunohistochemical PAP method. The morphology and distribution of Ec cells were observed under a light microscope, the number of cells per unit area was counted, and the cell area was measured by the IBAS1 system of the OPTON image analyzer. The results are as follows: 1. There was no significant difference in the number of antral gastric mucosal EC cells between the aged rats and adult rats,
