屏障

When any impairment occurs, the barrier can no longer exist and may result in enterogenous infection and multiple system organ failure and the burn patient may be in a serious state.

结果：完整的胃肠粘膜屏障应包括胃肠道完整的解剖结构，正常的生物菌群和健全的免疫功能，一方受到损害，胃肠屏障即不存在，直接后果是肠源性感染和多脏器功能不全综合征的发生，烧伤旋即进入持续性危重状态。

Mucous membrane protective screen is formed by the join between cell of alvine mucous membrane and cell, atrophy of cell of alvine mucous membrane, wither dies, cellular connective can send alvine path to connect flabbily appear a gender to increase, provide passageway; chemical protective screen for the bacterium inside bowel and toxin the digestive juice that shows epithelial excretive mucus and alvine memory are in bowel and digest enzymatic the chemistry that waits for material to reach its to develop.

黏膜屏障由肠黏膜细胞和细胞间的连接构成，肠黏膜细胞萎缩、凋亡、细胞连接的松弛可致肠道通透性增加，为肠内细菌及毒素提供通道；化学屏障指肠上皮细胞分泌的黏液及肠内存在的消化液和消化酶等物质及其发挥的化学功能。

The technology of culture of exogenetic NGF in vitro is qualified now, however, the exogenetic NGF cant get through blood-brain barrier and blood-nerve barrier because it is a kind of marcomolecular protein, thus its extensive application on clinic is limited, now, many scholors have turned their study direction to enhancing the content of endogenous NGF.

外源性NGF的体外合成技术已基本成熟，然而，外源性神经营养因子作为一种高分子蛋白物质不能通过消化道给药、不能通过血脑屏障和血神经屏障的问题阻碍了它在临床上的广泛应用，所以NGF在临床上并没有真正发挥出其营养神经的作用。

There are two systems in the portal system, namely, gastrosplenic GS system and portomesenteric system, and between the two systems there is a functional barrier. DSRS + SPD + Disconnection operation can strengthen this barrier.

在门静脉系统的肠系膜区与胃脾区两个功能区之间存在功能屏障，DSRS+SPD加断流术可增强这一屏障。

Results of scale model experiment of several typical urban road noise barrier s are presented,and optimizing scheme of designs road moise barriers are put forward in this the- sis.

本文给出了几种典型的城市道路声屏障缩尺模型实验方法及结果，并据此提出了道路声屏障设计的优化方案。

Vitamin E and quercetin are both effective anti-oxidant, but it is still unclear whether VE and quercetin can protect nerval system of mice through crossing placenta barrier and blood-brain barrier.

维生素E和槲皮素都是有效的抗氧化剂，但VE和槲皮素是否可以通过胎盘屏障和血脑屏障对子代小鼠的神经系统产生保护作用，目前还不清楚。

Methods Brain microvascular endothelial cells and neuroglial cells of newborn rats were cultured in vitro, and treated with 1,2-dichloroethane at a dose of 0 μl/ml, 5 μl/ml, 10 μl/ml or 20 μl/ml.

方法］在体外建立了血脑屏障细胞模型，并从形态学上观察1，2-二氯乙烷对血脑屏障细胞的损伤作用。

Interpretation NMO-IgG is a specific marker autoantibody of neuromyelitis optica and binds at or near the blood-brain barrier.

NMO-IgG抗体为视神经脊髓炎的特异性自身抗体标志物，在血脑屏障或血脑屏障附近结合。

They are already being evaluated in clinical trials as potential therapeutic agents for major human neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and motor neuron disease. However, delivery of polypeptide growth factors to compromised neurons in the CNS is problematic because their plasmatic half-life are very short and their abilities to cross the blood-brain barrier are theoretically null.

然而由于中枢神经系统中存在血脑屏障，神经营养因子类物质难以通过血脑屏障而到达靶部位；同时又因为神经营养因子在体内生物半衰期较短，使得全身性用药效果不够理想，另外还往往产生意想不到的副作用，如何解决这些问题对于深入研究神经营养因子在神经损伤及神经系统退行性疾病中的作用及开展临床应用前景研究有着十分重要的意义。

Environment changes in intestine cavity, specially changes of bacterium group, is vital to happening of bowel inflammation probably through antigen stimulation, metabolism of epithelial cells of intestine and penetrability to intestine wall and influence to conglutinating immune system.

但肠粘膜屏障的完整性可能由于关键基因分子决定簇郑州大学2004级临床医学硕士专业学位班炎症性肠病发病机制和治疗方面某些进展突变而减弱，肠腔内菌群的代谢产物穿透肠粘膜屏障引发固有膜免疫细胞的免疫反应。

Objective To investigate the effects of interleukin-1 β converting enzyme gene on the biologic characteristics of ovarian cancer cells.

目的 探讨白细胞介素-1 β转换酶的表达，对卵巢癌细胞生物学特性的影响。

Campylobacter: This illness is the most commonly identified cause of diarrheal illness in the world.
