人参,五加科植物人参(Panax ginseng C.A Mey)的干燥根,传统名贵药材,其用药已有两千多年的历史.其中人参皂苷是公认的有效成分,具有增强免疫力、抗肿瘤、抗衰老、益智、强心等药理学作用.人参与五灵脂配伍为传统中药"十九畏"内容之一,近年来,有些人从药理、临床方面对这两组中药的配伍进行研究,研究的结果存在分歧.有人认为五灵脂和人参配伍可以增强疗效;有人认为五灵脂的加入降低了人参的药效.为了进一步了解人参、五灵脂配伍实质,本试验通过药效学比较和有效成分分析,初步观察了人参和五灵脂配伍的相关问题. 相似文献

皂角苷又称皂甙或皂素,皂苷是糖苷类的化合物,苷又称配糖体,是由糖和非糖物质结合而成的一类化学成分.皂角苷的水溶液振摇后可产生持久的蜂窝状泡沫,与肥皂泡沫相似,因而得名.皂甙在植物,特别是在中药材中分布非常广泛(如著名的人参、三七等主要活性成份都是皂甙).近些年来,在中药领域,对皂甙的研究不断深入和广泛,目前已从人参中分离提纯出十八种人参单体皂甙,如Rb1、Rb2、Rd、Rc、Re、Rg1、Rg2、Rh1,并发现Rg1和Rb1最具药理活性.同时世界上也不断发现新的极具价值的皂苷化合物,如美国Antigenis公司著名的疫苗佐QS-21,单体分子量为1 990. 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
