奶牛子宫内膜炎的综合防制

奶牛子宫内膜炎是奶牛普遍发生的子宫内膜的炎症,是奶牛生殖系统的常见病,发病率高达20％～40％,包括急性子宫内膜炎、慢性子宫内膜炎、隐性子宫内膜炎、子宫积水和子宫积脓;急性期治疗不及时,或治疗不彻底而转为慢性,多为子宫黏膜的慢性炎症。临床上按炎症的性质可将慢性子宫内膜炎分为粘液性、粘液脓性、脓性、脓性假膜性和坏死性子宫内膜炎。该病对繁殖的影响依据炎症的程度、子宫内膜损伤恢复需要的时间、子宫内膜腺体的损伤、输卵管环境的改变不同而不同,子宫内膜炎使产犊间隔延长、产奶量减少、     

母牛子宫内膜炎的防治

繁殖母牛在配种，分娩接产或产后期，由于子宫内受到病原微生物的侵袭而发生子宫内膜炎。或母牛患有难产，胎衣不下等产科疾病，而继发子宫内膜炎。     

子宫切除术治疗犬子宫积脓症

子宫积脓症是指发情间期内脓性物质在母犬子宫腔内蓄积。子宫积脓症是子宫腔和子宫内膜的疾病,最终会导致子宫壁完全增厚,并会引起母犬全身症状。本病的主要原因是子宫内膜的囊泡状增生。母犬发情结束后,不论妊娠与否,功能性黄体可持续分泌黄体激素2个月以上。这种黄体激素长期持续作用于子宫内膜,引起子宫内膜囊泡状增生。这种状态的子宫对感染的抵抗力降低,     

奶牛产后子宫内细菌内毒素与子宫内膜炎的关系

试验通过对15头经严怀孕奶牛，严后1～9d提取严后子宫内容物样品，进行子宫内细菌内毒素的测定，探讨产后子宫内细菌内毒素与产后子宫内膜炎的关系。结果显示，产后第3～9天，子宫内细菌内毒素升高极显著（P〈0．01）的奶牛，经后来的调查发现发生子宫内膜炎。初步认为通过早期检测产后子宫内细菌内毒素的方法为预测子宫是否发生感染提供一定的依据。

子宫内注水法治疗羊子宫套叠

<正>子宫套叠又称子宫内翻。子宫套叠就是子宫角前端翻入子宫腔或阴道内。多发生在分娩之后,或产后数小时内发生。1诊断要点子宫套叠后母畜表现精神不安,努责举尾并有时起时卧等腹痛症状,经产道内检查可发现柔软圆形瘤样物。触摸患畜则疼痛加剧。     

奶牛子宫内膜炎的诊断及治疗

子宫内膜炎是奶牛场常见的疾病之一,也是不孕症的主要原因.从临床上可分为隐性子宫内膜炎、急性子宫内膜炎和慢性子宫内膜炎.依据粘膜损伤的程度,可分为慢性卡他性子宫内膜炎、卡他性脓性子宫内膜炎和坏死性子宫内膜炎.     

NO与子宫内膜炎奶牛子宫形态结构变化的关系

本研究旨在通过对血浆和子宫分泌物中NO浓度及奶牛子宫组织超微结构的变化来探讨NO在炎症反应中的作用及在子宫内膜炎惠牛早期诊断中的作用.选用产后健康荷斯坦奶牛5例(N)为对照组,亚临床型子宫内膜炎奶牛(SE)和临床型子宫内膜炎奶牛(CE)各10例,经颈静脉、子宫腔内分别获取血液样本及子宫分泌物;应用子宫内膜取样器获得每组奶牛子宫内膜样本,应用光镜和透射电镜观察子宫组织结构的变化.结果发现,SE组和CE组血浆和子宫分泌物中NO浓度均显著(P<0.05)和极显著(P<0.01)高于对照组;光镜和电镜下,SE及CE组奶牛的子宫内膜上皮细胞排列、细胞膜的完整性、细胞结构等均发生相应的变化.说明NO浓度随着炎症的发展而改变,炎症越明显,子宫内膜的变化越明显,NO浓度和牛子宫内膜超微结构的变化可作为诊断子宫内膜炎的一个依据

Disease and destiny-mystery and mastery

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.

Foot and mouth disease and bluetongue: differences and similarities

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.
