中肠

In feed add glucanase, xylanase, cellulose-based compound enzyme enzymes, anti-nutritional factors can degrade into small molecules fragments, the release of nutrients, reduce chyme viscosity, so that nutrition the material can be fully digested and absorbed to reduce the ileum bacteria substrate, inhibiting growth and reproduction of harmful micro-organisms to prevent diarrhea.

在饲料中添加以-葡聚糖酶、木聚糖酶、纤维素酶等为主的复合酶制剂，能够将抗营养因子降解成小分子片段，释放营养物质，降低食糜粘度，使营养物质能被充分消化吸收，减少回肠中细菌的底物，抑制有害微生物生长繁殖，防止腹泻。

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。

In zebrafish, the expression of fez becomes detectable at the anterior edge of the presumptive neuroectoderm by 70% epiboly.

本文用整体原位杂交的方法揭示了在斑马鱼胚胎发育过程中，Fez基因的表达最早出现在原肠期胚胎头部未来的神经外胚层细胞中，此时胚盘仅下包约70％。

The result showed no expression was detected in mantel, conductor muscle, intestine, sexual gland except in hemocyte.

结果表明，alpha-2巨球蛋白仅在血细胞中有表达，而在外套膜、闭壳肌、肠和性腺中没有表达。

Transcripts of zebrafish Hspa5 are present in fertilized eggs, suggesting their maternal origin. Zygotic expression of Hspa5 starts during midgastrulation and occurs in the hypoblast cells. It is specifically expressed in the hatching gland and the notochord during segmentation.

结果表明，Hspa5 mRNA在卵子中就存在，是一个母源基因；其合子基因的表达开始于原肠中期的下胚层，在体节期发生在脊索和孵化腺中。

This study proved that rutin could be directly absorbed into intestinal capillaries and lacteal ducts without hydrolysis by intestinal microflora.

本实验证明原型的芸香素药物分子可直接被吸收进入小肠绒毛中的微血管与乳糜管中，而不一定需要经过肠内微生菌丛的水解作用后才可被生体吸收。

Using reverse transcription PCR, kininogen mRNA was also detected in lamprey gut, kidney, and leukocyte, but absent in lamprey buccal gland.

运用反转录PCR技术，检测出激肽原还存在于七鳃鳗的肠、肾和白细胞中，但不存在于口腔腺中。

With Mab 2A3, the first positive cells were detected at the limb bud stage of the embryos. Distinguishable positive haemocytes with a diameter of about 7μm appeared in embryonic-nauplius. At the following nauplius I stage, configuration of haemocytes became more integrated and clear. Their diameters were almost similar to those of haemocytes from adult shrimp. With Mab 1H11, the first positive granular haemocytes were identified at the stage of embryonic-nauplius which existed in clusters with positive punctate fluorescence of granules distributed around the periphery of granular haemocytes.

通过对包括囊胚期、原肠胚期、肢芽期、膜内无节幼体期和无节幼体Ⅰ期在内的中国对虾胚胎的间接免疫荧光检测，最早在肢芽期胚胎中检测到2A3阳性信号；在膜内无节幼体期，2A3阳性血细胞平均直径约7μm，聚集成簇；在无节幼体Ⅰ期，血细胞形态更加完整清晰，平均直径已与成体对虾血细胞相似。1H11阳性大颗粒细胞最早在膜内无节幼体期胚胎中出现，这些细胞同样成簇存在，在其细胞质外围可见点状荧光。

ABSTRACT: Objective To study the effect of montmorillonite in promoting diffussion of creatinine from blood vessel to intestine and preventing absorption of creatinine in intestinal perfusate.

目的 研究蒙脱石对血管灌流液中的肌酐向肠道扩散的促进作用和阻止肠灌流液中肌酐的吸收作用。

Results: Large number of immunoreactive fibres was detected in lamina propria and muscularis mucosae. Strong staining of ganglion cells in the Auerbach's and the Meissner's plexus were observed on the normal specimens. There was very little or no immunoreactive fibre in the lamina propria and muscularis mucosae of the aganglionic bowel. However there was strong immunoreactivity in the perineurium of the hypertrophic nerve trunks in the submucosal and intramural layers of aganglionic segments.

结果： 正常肠段的粘膜固有层和粘膜肌层中有大量的P75NGFR阳性纤维，粘膜下和肌间神经丛中神经节细胞表现为P75NGFR强阳性，痉挛段肠管粘膜固有层和粘膜肌层中P75NGFR阳性纤维明显减少或缺如，粘膜下和肌间粗大神经纤维的神经束膜表现为P75NGFR强阳性，象一个环包绕在周围。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
