流行性出血热并发肝脏损害的检测及分析

对流行性出血热（EHF）患者并发肝脏损害169例进行血清GPT、GOT及其GOT／GPT比值、血钙、血糖、总胆红素、白蛋白、总蛋白等8项指标的检测报告。文章指出：对上述研究结果表明：EHF患者血清酶活性、GOT／GPT比值、血糖、总胆红素含量上升，白蛋白、总蛋白、血钙含量下降。这意味着EHF患者并发有肝脏损害，病情愈重肝损害愈明显。     

喂牛的草

一位游人旅行到乡间，看到一位老农把喂牛的草料铲到一间小茅屋的屋檐上，不免感到奇怪，于是就问道：     

牛的打嗝与放屁

俗话说：“管天管地，管不了打嗝放屁”。不过，近年来的研究表明，牛的打嗝与放屁所释放出的大量甲烷，已经成为造成地球变暖的一个重要因素，因而日益受到人们的关注。目前，世界多个国家的政府已经行动起来，纷纷制定法律法规，要求牛儿们必须“卫生地打嗝和放屁”。     

对氯苯酚与牛血清白蛋白的相互作用研究

利用荧光光谱法研究了对氯苯酚(4-CP)与牛血清白蛋白(BSA)的相互作用,研究结果表明4-CP对BSA的荧光有较强的猝灭作用,其猝灭机理为静态猝灭,作用力主要为氢键和范德华力.依据Lineweaver-Burk方程和热力学方程获得了不同温度下水溶液和表面活性剂溶液中4-CP和BSA作用的结合常数、结合点位数及热力学参...     

严重腹腔感染病人低白蛋白血症的多因素分析

分析影响腹腔感染病人血清白蛋白浓度的因素，及其与病情严重程度和预后的关系．收集６９３ 例肠外瘘病人入院后７２ｈ 内第一次的临床资料，将血清白蛋白浓度与其他临床指标进行多元回归分析和直线相关分析，并比较２６２ 例感染组和４３１ 例非感染组病人的血清白蛋白浓度和低白蛋白血症发生率．多元回归分析表明，血容量因素、感染因素、病情严重程度、病程及营养因素是影响病人的血清白蛋白水平的重要因素．感染组病人的低白蛋白血症发生率（９２ ．４ ％ ）明显高于非感染病人（３９ ．０ ％ ） ，其平均血清白蛋白浓度（（３１ ±６）ｇ／Ｌ） 明显低于非感染组（（３５ ±６）ｇ／Ｌ，Ｐ＜ ０ ．０１） ．腹腔感染病人的血清白蛋白浓度与死亡率显著相关（ｒ ＝０ ．３６ ，Ｐ＜ ０ ．０１） ．感染是影响血清白蛋白水平的重要因素，腹腔感染病人的血清白蛋白水平是预后和疾病严重程度的重要指标．     

猪瘟抗体水平的实验室检测技术

利用已知的血凝抗原检测未知的血清抗体，通过将抗原吸附（致敏）在红血球表面，再与相应的抗体结合，红血球便出现凝集现象，不仅肉眼可见，直观性强，而且反应的敏感性也大大提高。     

猪血清白蛋白基因5'端调控区的克隆与分析

根据已报道的hsa(人血清白蛋白基因)启动子序列设计了一对引物,以猪的基因组DNA为模板,采用PCR扩增出一条256 bp DNA片段,用Primer Premier5.0和Promoter Scan Ⅱ软件进行分析.结果表明,此序列为psa基因5'-端上游包括启动子在内的调控区,该区域含有一般启动子典型的CAAT-box、TATA-box等基本顺式作用元件.另外,还含有CTF/NF-1、CTF、APF、HNF-1、CP1等转录因子的结合位点.     

Albumin resuscitation protects against traumatic/hemorrhagic shock-induced lung apoptosis in rats

Objective： To determine the effects of albumin administration on lung injury and apoptosis in traumatic/hemorrhagic shock （T/HS） rats. Methods： Studies were performed on an in vivo model of spontaneously breathing rats with induced T/HS; the rats were subjected to femur fracture, ischemia for 30 min, and reperfusion for 20 min with Ringer＇s lactate solution （RS） or 5% （w/v） albumin （ALB）, and the left lower lobes of the lungs were resected. Results： Albumin administered during reperfusion markedly attenuated injury of the lung and decreased the concentration of lactic acid and the number of in situ TdT-mediated dUTP nick-end labelling （TUNEL）-positive cells. Moreover, immunohistochemistry performed 24 h after reperfusion revealed increases in the level of nuclear factor κB （NF-κB）, and phosphorylated p38 mitogen-activated protein kinase （MAPK） in the albumin-untreated group was down-regulated by albumin treatment when compared with the sham rats. Conclusion： Resuscitation with albumin attenuates tissue injury and inhibits T/HS-induced apoptosis in the lung via the p38 MAPK signal transduction pathway that functions to stimulate the activation of NF-κB.     

Elements in the Sera of Preschool Children Living in Central Taiwan

This study assessed elemental concentrations in the serum of 154 preschool children in central Taiwan via instrumental neutron activation analysis （INAA）. A total of eight elements, Br, C1, Fe, Na, Rb, Sc, Se and Zn of sera for Taiwanese preschool children living at four residential areas： Taichung city, Taichung urban townships and in a remote area inhabited by two groups of aborigines, Atayal and Bunun were determined. Standard reference materials （tomato leaves, NIST-SRM 1570a, and lichen, IAEA-336） were used as quality control standards to crosscheck the accuracy. Residential area, socioeconomic status and gender were shown to significantly influence serum levels of the eight trace elements. Statistical analysis revealed several different gender patterns via the two-tailed student＇s test. A quantified index of agreement （AT） was used to classify these elements. Small AT indicated a close consistency, while large AT indicated a larger fluctuation, or less agreement, such that the correlation between the elements could be interpreted using a series of quantified indices at the serum levels of preschool children.
