From 10 to 21 days after the operation, some of G cells showed gathering and some were found in upper portion of the pyloric glands and the number of G cells increased apparently ( P < 0.01). 细胞计数显示,术后10~21d,G细胞数量明显增多(P<0.01)。
Epithelia at gastric body and pyloric area sank inward respectively, forming simple tubular fundic and pyloric glands, no cardiac gland was found; 胃体及幽门区上皮分别内陷形成单管状的胃底腺和幽门腺,无贲门腺;
Pyloric caecums and intestine have a columnar epithelium. but have not the structure of glands in the mucous layer. 肠短,管壁厚,都具有柱状上皮,不具备腺体结构;
In I/ R2-4 groups, D cells were various in shape and were also observed in upper zone of the pyloric glands. 在I/R2-4组,则可见D细胞形态多样,并可见分布于幽门腺上1/3处。
Results: D cells were predominantly present in middle lower zone of the pyloric glands in control rats with various shapes. 结果:正常大鼠胃窦黏膜中D细胞主要分布于幽门腺的中、下1/3处,形态多样;
Observing from fundus gland to pyloric gland, as well as, from neck, body te bottom of the glands, the reaction of PNA binding was weakened progressively. 从界嵴循胃底腺至胃窦幽门腺的顺序观察,PNA结合反应显示逐渐减弱趋势;
In mice, the antral Gas-IR cells in the gastric antrum of mouse were aggregated in the lower zone of pyloric glands, smaller in size than those of the other animals, with a few of them showing protrusions too. 而小鼠胃窦黏膜中Gas-IR细胞主要集中分布于幽门腺的基部,细胞较小,也可看到胞质突起。
On the contrary, the pyloric glands, duodenum glands as well as main pancreatic duct glands are heavily stained with DBA, but various between the mucous glands stained with PNA. 幽门腺、十二指肠腺以及主胰管腺虽与DBA呈强阳性反应,但对PNA反应则不同。
In I/ R2 and I/ R3 groups, the D cells were markedly increased in number, varied in shape, and were also noticed in the upper zone of the pyloric glands. 在IR2组和IR3组则可见D细胞的数目明显增多,形态多样,并可见D细胞也分布于幽门腺上13处。
