目的 探讨乌司他丁对失血性休克大鼠回肠黏膜细胞凋亡的影响。

In rat esophagus, the positive varicosities and fibres could be observed in the circular muscle layer and the muscularis mucosae layer at 21st day before birth. With the development of rat digestive tract, neurokinin A-immunoreactivity positive nerves could be observed gradually in the epithelium, submucosa, longitudinal muscle layer, myenteric plexus and submucosal plexes, while mature nerve fibres could be seen at one month after birth. 2. In rat stomach, the positive reaction of NKA initially happened in the myenteric plexus at the 14th day of embryo, and then appeared on circular muscles, longitudinal muscles, submucosal, muscularis mucosae, lamina propria and epithelium. 30 days after birth, expression of NKA is same as seen in adaulthood. 3. In rat small intestinal, the NKA-IR could first be found in the myenteric plexus of the duodenum, jejunum and ileum at 14th , 15th and 17th day before birth respectively. Then the NKA-IR occurred in the longitudinal muscle layer, circular muscle layer, intestinal villus, intestinal gland, muscularis mucosae, submucosa, submucosal plexes, mucosa plexus and deep muscular plexus.

结果 1、在食管，于胚胎21天的粘膜肌层和环肌层内观察到神经激肽A免疫阳性膨体纤维，出生后，随幼鼠的生长发育，相继在上皮，粘膜下层，纵肌层、肌间丛、粘膜下丛有NKA-IR表达，30天时已和成年鼠相似；2、在胃，首先于胚胎14天的肌间丛出现NKA-IR的表达，随发育相继在环肌、纵肌，粘膜下层、粘膜肌、固有膜及上皮内出现NKA-IR的表达，30天时具备成年鼠的分布特征；3、在小肠，分别于胚胎14、15、17天的十二指肠、空肠和回肠的肌间丛处出现NKA-IR的表达，随发育相继出现在纵肌、环肌、绒毛、小肠腺周、粘膜肌、粘膜下层、粘膜下丛、粘膜丛、深肌丛。

Results Both of the propellant rates (P＜0.01) of charcoal powder in the small intestines of the mice were raised remarkably and the constriction (P＜0.01) of the ileum smooth muscle of the rat was greatly strengthened by Goldenrod Herb.

多斑艾美球虫主要寄生于空肠、回肠、盲肠和直肠绒毛中部到顶部的上皮细胞中，引起轻微病变。

The most commonly involved bowels were terminal ileum (12/15, 80%), cecum (9/15, 60%) and appendix (4/15, 27%).

最常好发的部位为回肠末端(12/15， 73%)，盲肠(9/15， 60%)及阑尾(4/15， 27%)。

肠系膜任一种将小肠和腹腔后壁联结起来的腹膜，尤指包被着空肠及回肠的这种腹膜

Results The morphology of endocrine cells in digestive tract was of multiplicity.The density of 5-HT cells was the highest in the colon,but not found in the esophagus,cardia gastric and cecum.The results showed that SS cells were distributed in the pylorus mostly,but not detected in the cardia,colon,cecum and rectum.Gas positive cells were the most in the duodenums,while in the esophagus and cardia was not discovered.In the cardia VIP cells were maximum,but in the esophagus,duodenums and ileum did not appear.

结果 消化道中4种免疫阳性细胞形态多样，大多呈椭圆形和锥体形。5-HT阳性细胞数量以结肠最多，空肠和回肠次之，幽门腺区、十二指肠和直肠较少，食管、贲门腺区、胃底腺区和盲肠中未见；SS阳性细胞在幽门腺区数量最多，贲门腺区、结肠、盲肠和直肠中未见；Gas阳性细胞大量出现于十二指肠，在食管、贲门腺区和盲肠未见；除个别器官未见VIP阳性细胞外，在消化道的其余各段均有分布。

Objective: to approach the application value of prophylactic terminal ileum stoma in the low-set rectal cancer protected anus operation.
