Our results demonstrate: The structures of the organs are normal, and the shapes of cells are clearly visible. There are lots of positive brown granules in Chief cells and Parietal cells in abomasum as well as the mucosa epithelial cells and gland cells of duodenum. Three bands with a molecular mass close to 120KDa、110KD and 98KDa were identified by Western Blot. The Ob-R levels of 120KDa in abomasum were significantly higher than that of in small intestine. The levels of 110KDa were similar in the two organs. The expression of 98KDa Ob-R was weak.

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，

Pancreatoduodenectomy is the routine operation performed for pancreas carcinoma. There is also operation plan suggesting the resection of the nerve plexus and soft tissue distributing along the artery vessels, and the nerve fiber bat around the pancreas. This operation is also named as skeletonization of the vasculature.

胰腺癌的主要治疗措施是根治性胰十二指肠切除术，也有的手术方案还建议切除胰腺周围沿动脉血管分布的神经丛和其他软组织，全部切除胰周区域的神经纤维板，即所谓的血管骨骼化。

Results In pancreatic cancer patients the positive rate of plasma K - ms gene mutation was 73 %, without false positivity, and higher than that in the pancreatic juice and duodenal juice, but lower than that in the fine - needle aspirates. Plasma K - ras gene mutation was not found in patients with benign pancreatic disease and healthy subjects.

结果 胰腺癌患者血浆K-Fas基因的突变阳性率为73％，无假阳性率，高于胰液、十二指肠液的检测率，低于细针穿刺的检测率；胰腺良性病变患者及健康对照者血浆中未检测到K-ras基因的突变；胰腺癌组K-ras基因突变与非胰腺癌组及健康对照组相比具有显著性差别。

Methods Charcoal powder propelling test of intestine was used to observe the effects of Na3VO4 on intestinal propulsive motility in mice. The change of constrictive activities of isolated duodenal tracts was determinated after Na3VO4 administration. The electrical potential difference was also measured across the wall of reverted intestinal sacs.

采用碳末推进实验观察经胃给予小鼠原钒酸钠后胃肠推进率的变化，同时应用离体肠管观察原钒酸钠对小鼠十二指肠运动的影响，并同步测量药物对翻转小肠囊的葡萄糖－钠转运电位的影响。

Nner Mongolian fine wool wethers of two years old with permanent ruminal and duodenal cannulas, divided into 4 groups of 3 at randomly, were used in this trail.

·一 试呛三：不同日粮阴阳离子水平的对绵羊生产性能及氮平衡的迈响选用12 ／q安装有永久性瘤胃窿管及十二指肠疹管的内蒙古半细毛羊渴羊，随机分成4组，每组3个重复，饲给4种不同阴阳离子水平日粮，以研究在大量饲g玉米秸秆条件下DCAB对绵羊干物质采食量（DMI人体重变化及氮平衡的形响。
