鸡胆汁有效成分CDCA和TCDCA的抗炎作用研究 总被引:14,自引:0,他引:14
采用比较药理学研究方法对鸡胆汁的有效成分鹅去氧胆酸 (CDCA)和牛磺酸鹅去氧胆酸 (TCDCA)进行了抗炎作用研究。结果显示 ,CDCA和 TCDCA均能极显著地抑制二甲苯所致小鼠耳壳炎症及小鼠皮肤毛细血管通透性增强。对小鼠棉球肉芽肿、大鼠角叉菜胶性足跖肿胀、大鼠甲醛性足跖肿胀以及炎性组织中 PGE2 含量具有明显抑制作用。对大鼠角叉菜胶性足跖肿胀和甲醛性足跖肿胀 ,CDCA和 TCDCA的作用与其剂量呈明显的正相关 ,且 TCDCA的抗肿胀率作用比 CDCA强。因而表明鸡胆汁的有效成分 CDCA和 TCDCA对急慢性炎症均有很强的抑制作用 相似文献

为研究夏枯草注射液的抗炎及抗菌作用,用二甲苯、蛋清分别造成小鼠和大鼠炎症模型来考察夏枯草注射液的抗炎作用,通过体外、体内抑菌试验来评价其抗菌作用。结果显示,夏枯草注射液能显著抑制Z-甲苯所致的小鼠耳肿胀和对蛋清致大鼠足跖肿胀,体外抗菌试验表明该注射液对痢疾杆菌、大肠杆菌、肺炎双球菌、溶血性链球菌有较好的抑菌作用,并对腹腔注射肺炎双球菌ATCC27853引起小鼠死亡有保护作用。夏枯草注射液具有抗炎、抗菌作用,可为该药的临床应用与机制研究提供理论依据。 相似文献

本试验旨在研究和探讨抗类风湿性关节炎(rheumatoid arthritis,RA)药物花艽-6的抗炎作用及其抗炎机理。采用二甲苯致小鼠耳肿胀法、醋酸致小鼠毛细血管通透性增高法、甲醛和蛋清致小鼠足跖肿胀法,以及棉球致小鼠肉芽组织增生法分别研究了该药物的抗急性、亚急性和慢性炎症的作用。通过复制佐剂性关节炎(adjuvant arthritis,AA)大鼠模型研究花艽-6对其血清中IL-1β、IL-6和TNF-α含量的影响。花艽-6对小鼠二甲苯所致的耳肿胀、醋酸所致的腹腔毛细血管通透性增高、甲醛和蛋清所致的足跖肿胀和棉花所致的肉芽组织增生均具有显著或极显著的抑制作用。花艽-6具有抗炎作用,可显著降低AA大鼠血清中IL-1β、IL-6和TNF-α的表达,对RA具有治疗作用。 相似文献

试验旨在研究乳腺康注射液体内外药效。体外药效采用牛津杯法对其进行体外抑菌活性研究;体内药效采用热板法及醋酸致小鼠扭体的镇痛模型、二甲苯及鸡蛋清致炎模型、2,4-二硝基酚及干酵母致大鼠发热6种经典药理模型,对乳腺康注射液进行镇痛、抗炎、解热的药效研究。结果显示,乳腺康注射液对大肠杆菌及金黄色葡萄球菌有较显著的体外抑制作用,中、高剂量能极显著提高小鼠痛阈值,极显著减少醋酸所致扭体次数(P<0.01),中剂量组能显著降低二甲苯致小鼠耳肿胀度及鸡蛋清致小鼠足跖肿胀度(P<0.05),中、高剂量组对2,4-二硝基酚引起的发热在1.5~2.0及3.0~3.5 h有显著的解热作用(P<0.05),对干酵母所引起的大鼠发热在1.0~3.5 h有显著的解热作用(P<0.05)。结果表明,乳腺康注射液能明显抑制大肠杆菌及金黄色葡萄球菌的活性,且具有显著的镇痛抗炎解热作用。 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
