Using mice , the researchers showed for the first time that tbi reduces the levels of a protein called potassium - chloride co - transporter 2 ( kcc2 ) within a portion of the brain called the dentate gyrus 通过耗子实验，研究者第一次发现创伤性脑损伤导致齿状回氯化钾协同转运酶水平降低。
In order to develop the three aspects of a language , task - based instruction ( tbi ) is fostered , and it has a greater and greater impact on language teaching in the world 为了使语言能力的三个方面( accuracy , fluencyandcomplexity )都得到发展，任务式教学法在世界范围内逐渐兴起，并显示出其巨大影响力。
The response of normal rats and only tbi conditioned rats spleen cells to balb / c and c57bl / 6 mice spleen cells were all violent , the values of si were 2 . 22 + 0 . 26 , 2 . 28 + 0 . 27 , 2 . 30 + 0 . 15 , 2 . 18 + 0 . 31 正常未经处理大鼠及只经tbi处理大鼠的脾细胞对balwc和c57bl历’ j ’鼠的脾细胞均有强烈增殖反应， si值分别为2
There have been isolated reports in the literature of the natural history and less than complete knowledge of the epidemiology and the pathophysiology of endocrine alteration occurring after traumatic brain injury ( tbi ) 摘要对于脑外伤病人于脑伤后体内内分泌改变的自然病程、流行病学及病理生理学只有少数的报告。
This article describes one primarily adrenal - dysfunction patient with severe tbi who had no evidence of present or prior adrenal autoimmune disease , infection , hemorrhage , or malignancy 本文报告一位无肾上腺自体免疫病、感染、出血及恶性肿瘤病史的严重脑外伤患者发生原发性肾上腺功能不全，呈现脑外伤引发原发性肾上腺功能不全的状况。
It could be applied to the forensic practice in expertizing the time course after traumatic brain injury . part ii the dynamically changes of map - 2 and the gene expression of map - 2 mrna after tbi microtubules play important functional and architectural roles in neurons 应用上海天能公司gis 700d凝胶图像分析系统对westernblotting后蛋白杂交条带进行扫描，并用脚与正常对照组密度之比，即相对密度值进行定量分析。
Second , balb / c mice were conditioned with 9 . 0gy lethal tbi and divided into two groups randomly . group a were injected with bone marrow cells 4x107 and speen cells 2107 from chimeric rats , and group b injected with bone marrow cells 4xl07 and speen cells 2xl07 from normal rats 第二步， balb c小鼠经至死剂量全身照射后随机分为两组， a组输入嵌合体大鼠的骨髓细胞和脾细胞， b组输入正常大鼠的骨髓细胞和脾细胞，比较gvhd发生情况。
Skehan ( 2002 : 228 ) pointed out task - based instruction could be considered simply a more thoroughgoing version of clt . it may be that versions of tbi with clear provision for focus on form will show that continued progress is possible in promoting accuracy and complexity as well as fluency 任务式教学法可以被看成是更加十足的交际教学法的翻版，它对语言形式的关注表明在语言的准确性、流利性和复杂性三方面都取得不断进步是可能的( 2002 ： 228 ) 。
The experiment includes two procedure . first , sd rats were conditioned with 5 . 5gy sublethal total body irradiation ( tbi ) , followed by infusion of balb / c mice bone marrow cells 8x107 on day 0 , then were intraperitonially administered cyclophosphamide ( cp ) 150mg / kg on day 2 . the procedure let sd rats become chimerism and have specific immunologic tolerance 实验分两步：第一步， sd大鼠经亚至死剂量5 . 5gy全身照射后，尾静脉输入balb c小鼠的骨髓细胞8 10 ~ 7 ， 2天后腹腔内注射环磷酰胺150mg kg ，诱导形成嵌合体大鼠，使其对balb c小鼠产生特异性免疫耐受。
Several genes and cytokines take part in the accommodation of these changes and influence the severity of brain injury , such as tumor necrosis factor a , bel - 2 gene family and ced gene family ( cystein - dependent aspartate - specific protease , caspase ) . they are all has relationship with cell death after tbi and control the different cascade of cell death . there are two kinds of cell death after traumatic brain injury ( tbi ) that is necrosis and apoptosis 脑外伤后脑组织发生的这些改变由许多基因、细胞因子参与调节并影响着损伤程度，除脑水肿外，脑损伤程度主要取决于细胞因子，这些因子包括肿瘤坏死因子- ( tumornecrosisfactor - , tnf - ) ， b细胞淋巴瘤白血病- 2 ( b - celllymphoma leukemia - 2 , bcl - 2 )基因中的bcl - 2 、 bax ， ced基因家族中的半胱天冬酶( cystein - dependentaspartate - specificprotease , caspase )等，它们都与脑损伤后的神经细胞死亡有关，控制着引起细胞死亡的不同层面。
