十二指肠内的

The objective of the study was to obtain the gene of bovine enterokinase light chain,which would be used in the cleavage and purification of fusion proteins.The fragment of bovine enterokinase light chain cDNA was obtained by RT-PCR from a sold bovine′s duodenal mucosa, then cloned into the pUCmT cloning vector and sequenced.Compared with the sequence deposited in GenBank,the cloned gene sequence is correct.

为克隆表达牛肠激酶轻链编码基因，以期应用于融合蛋白的切割与纯化，从市售北方黄牛十二指肠组织中提取总RNA，以RT-PCR方法扩增其cDNA片段，将此片段克隆于pUCmT载体中，经过特异性限制性内切酶酶切分析片段正确后，进行全序列分析。

Methods Clinical data of 15 cases of duodenal invasion by cancer of hepatic flexure of colon were analyzed retrospectively.

我院自 1 9 8 1年2月~ 2 0 0 2年 1 2月收治结肠癌侵犯十二指肠患者1 5例，并有 4例形成癌性内瘘，现就其外科治疗的有关问题报告如下。1 临床资料1。

Results:11 cases, 3 cases and 1 case located ileum, jejunum, duodenum respectively.

结果：位于回肠11例，位于空肠3例，十二指肠的1例。15例患者CT均表现为肠壁不规则增厚，单发13例，其中表现为结节型5例、壁内浸润型的6例、息肉样肿块型2例。

Objective To explore the treatment ways and effectiveness of metallic self-expanding stent in palliation of inoperable malignant gastroduodenal obstruction.

目的 探讨不能手术的胃十二指肠恶性梗阻金属内支架治疗方法和效果。

The typical roentgen features of intramural hematotha of duodenum are presented by UGI series, ultrasound and CT studies.

典型的十二指肠壁内血肿可由上肠胃道钡剂摄影，超音波与电脑断层来加以展现。

Results: NKA-I cells was first found in the duodenum mucose on the 14th day of fetus, earlier than in the jejunum ( 16th day ) and ileum ( 17th day ), and its Positive reaction and the number of cells increased with further development, after birth the 30th day, it became quite identical to that of adult rat; NKA-I cells were seen in the colon mucosa on the 17th day of fetus, later on the number kept decreasing till grown up stage; No change was observed in the stomach mucosa except that few cells showed up on the 15th day of fetus; No positive cell was found on the oesphagus wall.

结果： NKA-I细胞首先见于胚胎14 d的十二指肠粘膜，早于空肠(胚胎16 d)和回肠(胚胎17 d)，其阳性反应强度及细胞量随发育而增加，30 d时与成年鼠相似；结肠粘膜内于胚胎17 d见细胞，但此后数量较少直至成年；胃粘膜于胚胎15 d见个别细胞外，以后无明显变化；食道壁始终未见阳性细胞。

An upper gastrointestinal endoscopic examination revealed a polypoid mass moving to and fro between the stomach and the duodenum.

在上消化道内视镜检查的时候，我们发现一个肿瘤在胃和十二指肠之间来回移动。

Methods The bile duct of rabbit was excided and a pipe supporting bile duct was inserted through duodenal major papilla to establish a model. V.G staining and TGF-beta 1 immunohistochemistry staining on tubal wall of rabbit bile duct in different times were used to determine quantitatively the intensity of light TGF-beta 1 positive area and the relationship between the integral-optical density of bile duct tissue collagen content and time.

切开兔胆管并自十二指肠乳头行胆管内支撑方法建立模型，将不同时期梗阻段胆管壁进行V.G染色和β1型转化生长因子（transforming growth factor beta 1，TGF-β1）免疫组化染色，测定TGF-β1阳性区域的光度以及胆管组织胶原含量积分光密度随时间变化关系。

The location of the SS-,5-HT-,Gas- and VIP-positive cells mostly show up in the colon,the pylorus,the duodenums and the cardia respectively

消化道内5-HT、SS、Gas和VIP 4种细胞出现最多的部位分别是结肠、幽门腺区、十二指肠和贲门腺区。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
