To understand the role of the mucosa-associated microbiota in pathogenicity of ulcerative colitis, paired biopsies were obtained during colonoscopy from the ulcerated and nonulcerated gut mucosa of 24 patients with UC. The dominant bacteria and four important groups lactic acid bacteria, Clostridium leptum subgroup, Bacteroides spp.

通过PCR-DGGE技术比较24例溃疡性结肠炎患者肠道内溃疡粘膜以及与溃疡粘膜相距5cm的非溃疡粘膜所黏附的优势菌以及拟杆菌、柔嫩梭菌、乳酸菌和双歧杆菌的组成情况，结果表明同一肠段两个部位的优势菌组成很相似，而柔嫩梭菌及乳酸菌的组成存在很大的差异。

Nevertheless, even if the affected bowel loops at the abnormal anatomic location are not dilated and small internal hernias with low-grade obstruction are detected, we recommend that surgical colleagues use appropriate care to decrease hernial strangulation. Examples of such care include carefully monitoring the patient's vital signs and physical examination results or performing follow-up CT or gastrointestinal studies enhanced with intraluminal contrast material, including CT enteroclysis.

尽管处于异常解剖部位的受累肠管没有扩张，腹内疝较小，梗阻程度较轻，我们也推荐外科同事给予适当的护理减小疝性绞窄，例如详细的监护病人生命体征、进行体格检查、复查CT、使用管腔内造影剂的胃肠增强检查，包括CT肠造影术。

A variation in gastrulation involving the movement of cells into endodermal and mesodermal positions through the thickened primitive streak arose in reptiles and can still be seen in bird and mammalian embryos lending support to the theory that birds and mammals evolved from reptiles.

密实的原肠胚通过细胞运动进入内胚层和中胚层，爬虫，鸟，哺乳动物的胚胎都如此。因此提出这样的理论，鸟类和哺乳动物是由爬虫进化而来的。

Results totally 287 strains were isolated from the 256 positive samples , and the gram-negative bacilli were 225(78.4%,), the gram-positive coccus were 41(14.3%), snd the monilia were 21(7.3%).the distributions of clinical bacteria were respiratory tract(63.4%),urinaryract(7.0%),secretion(includingwound .3%),blood(5.9%),stool(5.2%), pucture fluid(4.9%), and other sites(7.3%). of all isolating bacterium,from the first to the fifth were ps.aeruginosa(19.5%),k.pneumoniae(16.7%), e.coli(14.3%), a.baumannii(11.8%) and psemal (10.1%).resistant rates of methecillin-resistant s.aureus,methecillin-resistant coagulase-negative staphylococci and vancomycin-resistantwere 88.2%、70.0% and 11.1% respectively;the incidence of e.coli and k.penumoniae produce extended speutrum beta-lactamase were 68.6%和65.2%, 44.6% of ps.aeruginosa isolates were resistant to imipenem; the highest examining rate of 21 kinds of monilia was candida albicans (66.7％),resistant rate of candida albicans to fluconazole and amphotricin b was 51.3％ and 1.3%.

结果 在254份检出细菌阳性标本中共培养出287株细菌，其中革兰阴性杆菌225株（78.4％），革兰阳性球菌41株（14.3%），念珠菌21株（7.3%），检出菌来自呼吸道标本占63.4%，其他标本各占5%左右；细菌检出占构成比前三位的依次为铜绿假单胞菌19.5%、肺炎克雷伯菌16.7%、大肠埃希菌14.3%；耐甲氧西林金黄色葡萄球菌、耐甲氧西林凝固酶阴性葡萄球菌和耐万古霉素的肠球菌的发生率分别为88.2%、70.0%和11.1%；大肠埃希菌和肺炎克雷伯菌的超广谱β-内酰胺酶的检出率分别为68.6%和65.2%，铜绿假单胞菌对亚胺培南的耐药率为40.2%；白色念珠菌对氟康唑的耐药率为81.3％，对两性霉素的耐药率为3.2%。

SECK: Nickerson explains that while we are subject to gravity, there are spaces within our bodies where it doesn't exert as strong a pull — like the lungs and intestines, where bacteria often multiply.

SECK先生：尼克森解释说，虽然我们受到重力的约束，我们的身体内有没有发挥的地方作为一个强有力的拉动，如肺，肠，往往在细菌繁殖-空间。

Bacteria affiliated with the most dominant phylotype, TG1, were endobionts of the flagellates Trichonympha agilis and Pyrsonympha vertens and were distributed all over the hindgut lumen area and close to the hindgut wall, in accordance with the distribution of the two flagellates.

在该白蚁肠道最占优势的&白蚁菌群1&类细菌主要是Pyrsonympha vertens和Trichonympha agilis这两种鞭毛虫的内共生菌，随着两种鞭毛虫的分布而遍布于肠腔各处及靠肠壁的区域。

The basolateral M cell surface is invaginated to form an intracellular central pocket into and out of which lymphocytes and macrophages.

M细胞是一种特化的上皮细胞，多分布于Peyer's结圆顶区的周边，FAE的顶端未见M细胞；其结构有别于相邻的肠上皮细胞，表面没有长而整齐的微绒毛，取而代之的是粗而短的微皱褶，胞质内终末网不发达，溶酶体较少，基底膜向顶部穹隆状突起，形成一&口袋&样结构，其中含有多个免疫活性细胞。

F951 distributes extensively into tissues,but the relative affinity varies enormously, being higher for kidney, liver, spleen and bone marrow and lower for heart, lung, brain, intestine, skin, fat and reproductive gland. At about 2 hours postdose, the concentrations of F951 reached the maximums and began to reduce slowly.

结果显示，F951在小鼠体内的分布不均匀，在肾、肝、脾、骨髓中分布浓度明显高于其它器官，在给药后8小时内单位重量组织中的F951含量教高，以后开始缓慢下降；F951在小鼠的心、肺、脑、肠、皮肤、脂肪、生殖腺中也有低水平的分布。

The colour patterns of the gut contents were recorded by video microscopy immediately after the alimentary canal was dissected out of the sandfly body,and used to deter...

此时期pH的降低，是利什曼感染型发生期。结论：本法可用于检测白蛉中肠的pH，具有简便准确等优点，通过对pH变化的检测，可间接反映肠道内利什曼感染型的发展变化。
