不同免疫增强剂影响肉鸡禽流感免疫效果及生长的试验 总被引：2，自引：0，他引：2
免疫调节剂是用于调节和控制免疫功能的药物,包括免疫抑制剂和免疫增强剂。免疫增强剂是一类单独使用或抗原同时使用、通过非特异性途径增强机体的免疫应答的物质。它可增强机体的免疫系统功能,缓解由环境造成的免疫功能紊乱,有利于预防和治疗传染性和条件性疾病。目前在临床上常用的免疫增强剂有很多,如：卡介苗、盐酸左旋咪唑、香菇多糖、胸腺素、白细胞介素-2（白介素-2）和黄芪多糖等等。本试验选用黄芪多糖粉剂、黄芪多糖注射液、盐酸左旋咪唑药物作为免疫增强剂,来探明不同免疫增强剂对肉鸡禽流感免疫功能和生长促进的影响差异。 相似文献

黄芪与左旋咪唑对雏鸡免疫功能影响的比较 总被引：18，自引：0，他引：18
以黄芪和左旋咪唑作为免疫增强剂，通过检测其对雏鸡抗体水平、体重、脾指数、法氏囊指数的影响，验证其免疫增强效果，并进行比较。试验结果表明，黄芪、左旋咪唑对雏鸡有很好的免疫增强作用，但在促生长方面存在差异。 相似文献

一定纯度中药复方多糖对鸡细胞免疫和体液免疫的影响 总被引：1，自引：1，他引：0
为筛选对鼠免疫增强效果显著的一定纯度中药复方多糖(cCHMPS)对雏鸡的最佳免疫增强剂量,本试验将300只1日龄雄性良凤青脚麻鸡随机分为6组,即空白对照组、盐酸左旋咪唑组、黄芪多糖组及cCHMPS高、中、低剂量组,每组各50只.分别于8日龄皮下注射生理盐水、盐酸左旋咪唑、黄芪多糖及不同剂量的cCHMPS,连续7 d,在免疫后第8、14、21、35、42天采血,测定外周血中T、B淋巴细胞增殖活性及血清中新城疫病毒抗体含量.试验结果表明,黄芪多糖和不同剂量cCHMPS均能显著或极显著促进外周血T、B淋巴细胞增殖(P<0.05;P<0.01),提高新城疫病毒抗体浓度,增强机体细胞免疫和体液免疫水平,且中剂量的cCHMPS的免疫增强效果最好. 相似文献

选择14日龄雏鸡110只,随机均分为11组,Ⅰ组为对照组,Ⅱ～Ⅺ为试验组,各组雏鸡在14日龄时均颈部皮下注射鸡ND—La Sota疫苗0．2ml／只．试验组雏鸡同时经口投服由不同配方和比例黄芪多糖、淫羊藿多糖、左旋咪唑、维生素E和亚硒酸钠制备的10种缓释复方免疫增强剂1粒,对照组雏鸡不投服。在免疫前后不同时间采血测定各组雏鸡ND—HI抗体效价和T淋巴细胞ANAE阳性率．结果表明制备的10种缓释复方免疫增强剂均不同程度地提高了雏鸡ND—HI抗体效价和T淋巴细胞ANAE阳性率．其中以X组和Ⅺ组配方效果最好,为今后研制缓释复方免疫增强剂奠定了基础。 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

近几年,世界饲用添加剂市场增长较快,预计今后将进一步增长,据世界粮农组织(FAO)首领会议的倡议,到2015年,将使世界营养不良的人口削减一半,其间,肉制品将会以每年2％的速度增长,特别是加快猪肉和禽肉增长。这将促进世界添加剂,尤其是蛋氨酸和赖氨酸需求量的增加。 相似文献
