在活体内

However, incubation of cells for 72 hrs in the presence of nicotine and/or arecoline treatments and antibody against IL-1αor IL-1βsignificantly increased cell growth as compared with the antibody free one.

这些结果建议在活体内IL-8的分泌会受到IL-l 局部产生的特殊调节。

Since 1991, the teaching group of veterinary pathology in Inner Mongolia Agricultural University have accomplished 3 research subjects supported by the National foundation of science and technology. In the process of research, a local AEV strain, the AVE-NH937 strain, was isolated and established. The detailed pathological lesions and the dynamic location of AEV in natural and experimental cases of chicken, chickling and embryos were reported.

全世界和我国的科学工作者对本病进行了广泛的研究，内蒙古农业大学兽医病理学科自1991年，连续3次获得国家自然科学基金委员会的资助，分离并建立了AEV-NH937株，系统描述了自然病例和人工感染的成年鸡、雏鸡、鸡胚的病理变化，人工感染后AEV在鸡体内的动态分布，并制备出琼扩抗原和灭活油乳剂疫苗用于临床检测和预防，取得了重要研究成果。

These results show that codA gene cloned from E. coli can express specifically in the anther of both monocotyledon and dicotyledon plant species upon induction of 5-FC, and the in vivo expression product of the gene can transform the 5-FC used externally into 5-FU, which leads to all or partial inactivity of anthers and/or pollens.

以上结果表明，codA基因在单子叶植物和双子叶植物花药中的特异性表达，能将外用的5-FC在体内转化为5-FU，导致花药或花粉的部分和全部失活。

A GFP-labeled Hela cell line and a mouse tumor model based on the cell line were established, and the animal model provides useful experimental materials for cervical cancer study. The in vivo fluorescence imaging system could be used to quantitatively evaluate the living tumor cell growth in vivo but not the size or volume of the tumor detected by slide caliper.

绿色荧光蛋白能够在人宫颈癌细胞Hela中长期稳定表达，用绿色荧光蛋白标记的人宫颈癌细胞Hela建立的裸鼠肿瘤模型可以为人宫颈癌研究提供理想的实验材料，应用小动物活体成像系统能够客观定量评价活的肿瘤细胞在动物体内的生长情况，而不是肿瘤体积的变化。

Conclusions— Our results provide the first evidence that CathA acts in vivo as an endothelin-1–inactivating enzyme and strongly confirm a crucial role of this enzyme in effective elastic fiber formation.

结论——我们首次证实CathA在体内发挥了内皮素-1–灭活酶的作用，并证实其在有效弹性纤维形成中有重要作用。

利用多种细胞因子促进细胞向成骨细胞的分化，以保证细胞在植入体内后能够保持并充分发挥其成骨活

Methods:(1) Dissoluble PGN and CpG DNA were immobilized onto the surface of biotin cuvette for establishing target. Another effective tracking approach was established by immobilizing Escherichia lipid A F583 onto the surface of Non-derivatised cuvett. The biosensor technology was applied to screen anti-inflammatory TCM targeting on three key molecules.(2) The active compositions were isolated by AB-8 macroreticular resin from lycium bark. After the activities of compositions were evaluated, the most effective compositions was confirmed. In vitro, the affinities of different concentrations composition E binding with PGN, CpG DNA and lipid A were measured separately. The effect of composition E on vigor of RAW264.7 cells were tested by MTT and CCK-8, and its inhibition on TNF-α, which was released from RAW264.7 cells induced by PGN, CpG DNA and LPS, was also tested by ELISA. In vivo, murine sepsis models were made by intravenously heat-killed E.coli and heat-killed S.aureus, then protection of composition E on mice sepsis model were observed.

(1)将PGN及CpG DNA包被于生物素样品池，将lipid A包被于非衍生样品池，分别建立以PGN、CpG DNA及lipid A为靶点的技术平台，对114种抗炎中药水提物进行筛选、评价其活性物质含量，并评估出针对上述三种病原分子均具有较高结合活性的中药；(2)利用生物传感器跟踪检测技术、大孔吸附树脂分离技术，从地骨皮中定向分离与PGN、CpG DNA及lipid A均具有较高亲和力的活性组分；在体外实验中，测定不同浓度活性组分与PGN、CpG DNA及lipid A亲和力；MTT法及CCK-8法检测活性组分对RAW264.7细胞活力的影响；ELISA法检测活性组分对PGN(2μg/ml)、CpG DNA(10μg/ml)及LPS(100ng/ml)刺激小鼠RAW264.7细胞分泌TNF-α的抑制作用；在体内实验中，采用尾静脉注射致死剂量热灭活大肠杆菌和热灭活金黄色葡萄球菌，建立细菌脓毒症小鼠模型，观察活性组分对脓毒症模型小鼠的保护作用。
