The beginning portion of the small intestine,starting at the lower end of the stomach and extending to the jejunum.

十二指肠小肠的开始部分，开始于胃的底部，伸入空肠它充满并推向细胞的顶部，迫使核移向狭窄的基部。

The GLUT2 mRNA expression were not affected by xylanase whether in duodenum or in jejunum.

而木聚糖酶对GLUT2 mRNA表达的影响，在十二指肠和空肠均无显著变化。

In order to clone the VIP gene in the gastrointestinal tract from beijing duck, one pair of specific primers to VIP gene was designed and synthesized according to the chick sequence (X80906). Encoding VIP cDNA fragments were amplified by RT-PCR from the total RNA in the Proventriculus, the Duodenum and the Jejunum of Beijing duck. Their PCR products were ligated into pGEM-T easy vector, which was transformed into E. coil JM109. Positive bacteria clones were screened and identified by PCR method and digested with the double restriction enzyme EcoRⅠ. The sequence of VIP gene fragment was also determined and analyzed.

为从北京鸭胃肠道中扩增血管活性肠肽基因，根据鸡VIP基因（GenBank登录号X80906），设计了一对简并引物，从北京鸭腺胃、十二指肠和空肠提取总RNA，通过反转录－聚合酶链反应扩增，将从腺胃、十二指肠和空肠中扩增出的产物克隆到pGEM-Teasy载体上，导入大肠杆菌JM109，阳性克隆经双酶切鉴定后测序，将测序结果与鸡和鹅（GenBank登录号为DQ023161）的VIP基因进行同源性比较。

RouxenY reconstruction after gastrectomy offers well outcome for the treatment of peripapillary duodenal diverticulum.

Based on preliminary pharmacodynamical test on animals, the inhibition of gastric acid secretion of FM—DDS is better than its ordinary tablets, and the antiulcerative effect is better as well.

根据体外溶出试验表明，FPRP在服药10小时后脉冲式释药，这时药物应是到达回肠以下部位，为此，进行了药物肠道吸收部位及吸收机理的研究，结果表明：法莫替丁在十二指肠、空肠、回肠、结肠等部位均有吸收，其吸收量顺序：十二指肠＞空肠＞回肠＞结肠，其吸收机理属于被动扩散。

Result: The absorption rates in rat stomachs at 2 h after administration was 76.31%; The absorption rates at colon, duodenum, ileum and jejunum were 46.25%, 40.54%, 38.21%, 32.77%, respectively. The absorption rate constant at concentrations of 10.014 4, 20.028 8-40.057 6 mg·L-1 in intestine were 0.643 4, 0.613 7, 0.597 0 h-1, respectively. The K a of scopoletin at pH of 6.0, 6.8 and 7.4 in intestine were 0.621 7, 0.603 3, 0.613 7 h-1, respectively.

结果：东莨菪素在大鼠胃中2 h的吸收百分率为76.31%；东莨菪素在结肠、十二指肠、回肠、空肠的吸收率分别为46.25%，40.54%，38.21%，32.77%；不同质量浓度东莨菪素10.014 4，20.028 8，40.057 6 mg·L-1在小肠的吸收速率常数分别为0.643 4，0.613 7，0.597 0 h-1；不同pH(6.0，6.8，7.4在小肠的吸收速率常数分别为0.621 7，0.603 3，

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。
