肠阻塞骡不同舌色的载体血液黏度和微循环功能的变化 总被引：1，自引：0，他引：1
研究采用无创伤性方法测定了45匹健康骡和130例肠阻塞病骡不同病理舌色的载体血液黏度和微循环的功能指标，结果表明：暗红、青紫、赤红和红这4种病理舌色的载体血液黏度均高于正常组（P＜0.01），正常组和淡红舌组之间差异不显著（P＞0.05），而且随着舌色由淡红→红→赤红→暗红→青紫的发展，血液黏度也逐步升高，MRT、MST也逐步升高，MHR则正好相反。这一结果说明血液流变学性的变化和微循环功能的改变对舌色的形成机理具有意义。 相似文献

用血液流变学方法测定了27匹健康成年骡和188例病骡的全血黏度、还原全血黏度以及血细胞压积、红细胞电泳时间。结果显示：随着舌色由淡红、红、赤红、暗红的转变，7种切变率下的全血黏度、还原全血黏度以及血细胞压积、红细胞电泳时间逐渐增加。其中全血黏度、还原全血黏度、血细胞压积差异显著或极显著（P〈0．05或P〈0．01）。淡红、红、赤红、暗红四种舌色的全血黏度和还原全血黏度均随着切变率的增加而逐渐降低。这一结果说明，血液流变学主要指标与家畜舌色之间存在密切关系。 相似文献

采用单因素随机分组试验设计,将15头泌乳中期荷斯坦奶牛随机分为3组,每组5头,进行为期60 d的饲养试验.每组奶牛分别饲喂不同日粮:Ⅰ组(基础日粮)、Ⅱ组(基础日粮+200 mg大豆黄酮/d)、Ⅲ组(基础日粮+200mg染料木素/d),试验期60 d内每隔15 d晨饲前空腹采集血样,进行血液生化及流变学指标分析.结果显示,大豆黄酮组(Ⅱ组)球蛋白(GLOB)含量显著高于Ⅰ组(P<0.05);Ⅱ组和Ⅲ组总胆固醇(TC)、甘油三酯(TG)含量分别较Ⅰ组显著降低(P<0.05);Ⅱ组高密度脂蛋白(HDL)显著高于Ⅰ组(P<0.05),但与Ⅱ组差异不显著(P>0.05);Ⅲ组同Ⅰ组相比显著降低了低密度脂蛋白(LDL)的含量(P<0.05);血清钙含量Ⅱ组和Ⅲ组分别较Ⅰ组显著提高(P<0.05),其他各项血常规指标组间差异不显著(P>0.05);奶牛血液流变学方面,大豆黄酮和染料木素的添加在一定程度上有显著降低奶牛全血粘度(ηb)及相应全血还原比粘度(ηr)、血浆粘度的作用(P<0.05);各组红细胞压积(PCV)、红细胞聚集指数(AI)差异不显著(P>0.05);红细胞刚性指数(IR)Ⅱ组和Ⅲ组均显著低于Ⅰ组(P<0.05);纤维蛋白原(FG)含量组间差异不显著(P>0.05). 相似文献

运用无创伤性检查技术对３５匹健康凉州驴和４５匹病驴舌色进行了测定，以探讨舌色与血液粘度和血液微循环之间的关系。结果：与正常舌色（淡红色）相比，红绛舌时，血液粘度增高（Ｐ＜０．０１），微循环半更新时间（ＭＲＴ）、微循环平均滞留时间（ＭＳＴ）延长（Ｐ＜０．０５，Ｐ＜０．０１），而在其他病理舌色时差异不显著（Ｐ＞０．０５）。与淡白舌相比，血液粘度在红绛舌、红舌时增高（Ｐ＜０．０１）；ＭＲＴ、ＭＳＴ在红绛舌时延长（Ｐ＜０．０１）。在其他病理舌色之间，血液粘度、ＭＲＴ、ＭＳＴ差异均不显著（Ｐ＞０．０５）。 相似文献

When early people made their appearance, zoonotic infectious diseases were already waiting, but epidemic diseases did not appear in human history until people began to live in large numbers under conditions of close contact, mainly during the last 10,000 years. Disease has decimated urban populations, conquered armies, and disrupted society. The focus here is on (1) the plague of Athens and the Black Death; (2) smallpox, influenza, and rabies; (3) avian influenza prion diseases, and foot & mouth disease; and (4) emerging and re-emerging diseases. All have veterinary public health associations. In Athens, Greece, in 430 BC, when the Spartans ravaged the countryside, hordes crowded into Athens so that orderly movements, space in which to live, and adequate supplies of food became impossible. Crowding of any population fosters disease transmission; chaos and disorder enhance it all the more. Out of northern Egypt came a terrible plague from across the Mediterranean Sea. The identity of the plague of Athens remains unsure, but the well-considered conclusion is Rift Valley Fever, a mosquito borne, viral zoonosis. The Black Death, also called the Plague, raged in Asia for centuries. In 1347, the Black Death was brought by a ship out of Asia to Sicily. The scenes of devastation were repeated throughout Europe, with 90% or more of the people dying in city after city. Influenza, too, has been a cause of periodic human epidemics, but the great pandemic of influenza occurred in the last months of World War I. In the years of highest occurrence, more than half the world's population became clinically infected. If veterinary public health had been born earlier, it could have led to elucidating the epidemiology of influenza and the plagues of Athens, Europe, and Asia. In turn, smallpox had also caused continual tragedy. In 1796, Edward Jenner began to harvest pustules of cowpox from children or infected cows and inject them into susceptible children. In 1980, the World Health Organization declared that smallpox had been eliminated from the world. Rabies, though, still strikes terror. A number of animal diseases, broadly termed emerging and re-emerging diseases, need surveillance because they have the potential to impact human health. From late in 2003 to 2007, the highly pathogenic H5N1 influenza virus in poultry infected at least 121 people and caused 62 deaths in four countries. The prion diseases, too, all have very high numbers in concentrated contacts. To control these diseases, veterinary public health is essential, with diagnosis, epidemiological surveillance, clinical manifestations, and prevention as primary measures. 相似文献

On 26th of july 2007 a new case of bluetongue was notified in the Netherlands and on 2nd of august 2007 foot-and-mouth disease was diagnosed in Surrey, England, which raised the threat of having both infections simultaniously in one area. Bluetongue and foot-and-mouth disease have a different pathogenesis, but symptoms may resemble each other at a later stage of infection. The pathogenesis and possible clinical symptoms of both infections are discussed and illustrated with pictures. 相似文献
