幽门腺

在大鼠胃窦黏膜中，Gas-IR细胞主要分布于幽门腺的中、下1/3处，细胞大小不等，形态多样，可见细胞发出细长的胞质突起，伸向邻近细胞或腺腔。

In the gastric antrum of rat , the Gas-IR cells were predominantly located in the lower third of the pyloric gland , varied in shape , with thin protrusions found in some cells projecting between adjacent cells or into the acinar cavities .

具有胃腺窝上皮型和幽门腺型特定型粘液。

正常胃窦粘膜上皮和幽门腺细胞分裂指数为5.93±1.23（x±s，下同）；

In normal control group , the mitotic index of the antral mucosal epithelial and glandular cells was 5.93 ± 1.23 ;

结果显示，在与大肠化生区相邻的胃粘膜，G细胞突然消失，假幽门腺化生也缺乏G细胞，而小肠化生仍保留少数G细胞；

The results , showed that G cells well absent both in mucosa adjacent to clonic metaplasia and pseudopyloric metaplasia while they were still present , though fewer than normal , in small intestinal metaplasia .

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；

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 .

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。

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 .

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。

In I / R2-4 groups , D cells were various in shape and were also observed in upper zone of the pyloric glands .

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。

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 .

The pathological changes of tubular adenoma were complex and various , showing the trend of multi differentiation , such as colonic gland , pyloric gland , and squamous epithelia differentiation .

组织化学研究表明，贲门腺和幽门腺主要由粘液细胞组成，但在腺管底部也可能具有壁细胞和主细胞；

Study of showed that the cardiac gland and pyloric glandular mainly by the mucus cells , but also may have Xianguan at the bottom of the wall and the main cells ;

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。

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 .

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；

Epithelia at gastric body and pyloric area sank inward respectively , forming simple tubular fundic and pyloric glands , no cardiac gland was found ;

幽门螺旋杆菌感染标本的胃体部黏膜中，三叶因子1在固有层颈黏液细胞和假幽门腺化生细胞中表达，其阳性表达率与黏膜萎缩程度有关。

RESULTS ? In gastric fundic mucosa infected with HP , the TFF ? 1 was expressed in mucous neck cells and pseudopyloric gland metaplasia , and related to the atrophy of mucous membrane .
