Initial adherenced cells mostly are round or short fusiform. Division growth of adherenced cells was shown 72 hours after fully changing suspension(.2)Flow cytometry analysis of the adherenced MSCs indicated good homogenicity of passage cells. More than 95% CD34- and CD44+ demonstrated the cells we get were purified MSCs.

The results revealed that the uroliths of goats associated with feeding cottonseed meals diet were the mixture of amount powdery and few granular. X-ray radiology of 'sandy uroliths' feeding cottenseed meals diet to goats was negative. Intravenous urography demonstrated granules of uroliths in the bladder with different density.'sandy uroliths' in kidney, bladder and sigmoid flexure were found with B-mode ultrasonogram.

结果显示：饲喂棉饼诱发的山羊泌尿系统结石呈砂石样，X射线腹部平片呈阴性，经泛影葡胺静脉尿路造影后可见膀胱内有密度不均匀的结石样颗粒分布；B超检查在泌尿道多处出现结石颗粒的强光点或光团并伴有声影；螺旋CT检查发现在泌尿系统的膀胱和尿道中有明确的结石影。

The masculine Sun is the particular significator of the marriage partner in a woman's horoscope , and the feminine Moon signifies the spouse in a man's chart.

阳性的太阳，在女生的命盘中有着丈夫的特殊含义，而阴性的月亮在男性命盘上则意味着妻子。

Mainly using protein - film voltammetric technique, we have achieved direct electrochemical response of lots of proteins such as hemoglobin, myoglobin, cytocrome c, cytocrome b5, horseradish peroxiase, GOD ,Vitreoscillia sp. haemoglobin, etc., at a series of protein membrane modified electrodes, for instance, protein/kieselgubr, protein/polyethylene glycol, protein/polyethyleneimine, protein/phosphatidylcholine, protein/DNA, protein/montmorillonite/polyvinyl alcohol, protein/silver nanoparticle/ cysteamine membrane modified electrode, etc., which are prepared by casting, incorperating or layer by layer self-assembly methods. Electrochemical behavior of these proteins in the films have been studied, and their structural and conformational changes have also been examined with spectrometric techniques.

三年来，在基金委的支持下，我们以蛋白膜伏安法这一新技术作为主要的研究手段，并结合其他生物、化学技术，研究了血红蛋白、肌红蛋白、细胞色素C、细胞色素b5、辣根过氧化物酶、葡萄糖氧化酶以及好氧革兰式阴性菌透明颤菌中的血红素类蛋白等多种蛋白质在以涂布和自组装方法制成的蛋白质/硅藻土膜、蛋白质/聚乙二醇膜、蛋白质/卵磷脂膜、蛋白质/聚乙烯亚胺膜、蛋白质/蒙托石/聚乙烯醇自组装膜以及蛋白质/银胶/半胱胺自组装膜等修饰电极上的直接电化学行为，结合各种光谱技术，对蛋白质在膜中的构象进行表征，探索其电子传递机理。

If a pool tests positive for HIV, the individual sample can be detected and removed for further processing, and the donor can be deferred and notified (Kaiser Daily HIV/AIDS Report, 8/19/04). Because NAT looks for the virus and not antibodies, health professionals are able to identify HIV-positive patients in the days immediately following infection -- when they are most contagious -- which could help slow the spread of virus.

研究者以标准的艾滋病病毒抗体检测法检测时发现583例艾滋病病毒呈阳性反应的受试者，但是当他们用更加成熟的核酸扩增法检测那些呈阴性反应的受试者的时候，又发现了另外的23例病毒。

Complicated working conditions, such as water-retaining structures to bear a lot of water pressure, Seepage from the osmotic pressure of building the strength and stability negative; sluiceway discharge structure, right bed and bank erosion has a strong role.

使工作环境复杂化，例如水保留的结构负担很多从建立力量和稳定阴性渗透压的水压，渗流；闸沟放电结构、正确的床和银行侵蚀有一个强的角色。

The SMMC-7721 hepatoma cell line of experimental groups and control groups were cultured with the addition of sodium selenite, potassium iodide or triiodothyronine (T3). The cell quantity was checked by the MTT assay , and the cell cycle was observed by flow cytometry and levels of AFP and ALB in the culture solution were determined by RIA.The SD rats were divided into positive control group, negative control group, T3 group and mixture group (the mixture of sodium selenite, KI and T3). After two weeks of the administration of sodium selenite、 KI and T3,Walker256 cells were transplanted into the abdominal cavity. The administration was kept on for another two weeks, then observed the morbility and mortality of the rats with ascites carcinoma. At the end, the ascites were for the cells counting and the cell cycles analysising.

方 法：在体外，应用细胞培养的方法，培养SMMC－7721肝癌细胞系，分为试验组和对照组，试验组加入不同浓度Se、I或T3干预，培养一段时间后，通过噻唑蓝试验、流式细胞仪，观察细胞数量及细胞周期的变化，测定细胞培养上清液中甲胎蛋白、白蛋白的水平，观察细胞分化情况；在体内，将试验用SD大鼠分成阴性对照组、阳性对照组、T3组和混合组（为Se、I和T3混合物），首先预防性用药2周，然后给试验组大鼠和阳性对照组大鼠腹腔注射Walker256细胞，制造腹水癌大鼠模型；继续用药2周，观察各组大鼠发病率及死亡率，测量不同时期大鼠血清FT3含量，通过流式细胞仪测量大鼠腹水细胞数及细胞周期变化。
