Courses for horses: Rethinking the use of proton pump inhibitors in the treatment of equine gastric ulcer syndrome

Oral omeprazole has been the cornerstone of equine gastric ulcer syndrome (EGUS) treatment for nearly 20 years. However, approximately 15–30% of equine squamous gastric disease (ESGD) cases and 75% of equine glandular gastric disease (EGGD) cases fail to heal within current treatment guidelines. Recently, a number of factors that may affect the efficacy of oral omeprazole have been highlighted and the pharmacodynamics of a number of novel proton pump inhibitors (PPIs) have been described in the horse. The purpose of this article is to review the factors that affect oral omeprazole efficacy, with the goal of maximising therapeutic response, and the novel PPIs recently described.     

免疫抑制对苏拉灭和贝尼尔治疗小鼠伊氏锥虫病疗效的影响

用从自然感染宿主分离的伊氏锥虫原种ＪＧ的克隆ＪＧｍｃ１和ＪＧｍｃ５感染免疫活性正常小鼠和免疫抑制小鼠，２４ｈ后，以苏拉灭或贝尼尔治疗，两种药物对免疫抑制小鼠的ＣＤ１００均明显高于免疫活性正常小鼠，由经受一次苏拉灭或贝尼尔治疗未愈的免疫抑制小鼠分离的锥虫，感染免疫活性正常小鼠，再用原来对该克隆感染的免疫活性正常小鼠ＣＤ１００的苏拉灭或贝尼尔治疗即无效。用免疫溶解试验分别测定一组免疫抑制和免疫活性正确

羊传染性胸膜肺炎防治

羊传染性胸膜肺炎是一种高度接触性传染性疾病,致病原是肺炎支原体。妊娠阶段的母羊受到病原侵染后表现为流产产下死胎,并表现出明显的繁殖障碍。近年,此病发生率逐年升高,造成的死亡现象不断增强,严重威胁养殖产业健康发展。作为养殖管理人员,应从该种疾病的流行病学、临床表现、病理变化和诊断方法等多角度入手,构建针对性的防治措施,严格落实预防为主的原则,为提高养殖效益奠定坚实的技术支撑。该文主要探讨羊传染性胸膜肺炎的防治过程。

甘肃省坡耕地利用状况与退耕还林还草技术对策研究

对甘肃省坡耕地的利用状况及其退耕的可行性进行了较为全面的分析,按照因地制宜的原则,将退耕区域划分为陇中黄土丘陵沟壑区、陇东黄土台塬区、山高坡陡的陇南山区与河西防风固沙区四大区,并就各区退耕后的还林还草方式进行了具体的论证,提出了15°～25°和25°以上坡耕地退耕还林还草的具体技术对策。     

覆膜垄沟集雨种植对老芒麦高度和密度的影响

研究了北方农牧交错区垄沟集雨种植措施对老芒麦Elymus sibiricus生长发育的影响。覆膜垄沟集雨种植可以使有限降雨在沟内富集累加,垄面径流效率达到80%左右。老芒麦2008和2009年营养生长阶段,处理间高度差异显著。2008年处理1和CK相比,株高提高33.5%~61.3%;处理2和CK相比,株高提高20.1%~44.1%,处理1与处理2相比,株高提高9.2%~16.2%。2009年处理1与CK相比,株高提高93.2%~116.4%;处理2与CK相比,株高提高65.4%~82.3%;处理1与处理2相比,株高提高12.1%~19.4%。处理1、处理2与CK三者在密度方面差异不尽相同,总体表现出处理2和处理1老芒麦密度高于CK,2008年密度动态变化和单株分蘖数变化保持一致,2009年返青后,呈现出整体略微下降趋势,趋于稳定。     

科尔沁沙地灌溉与施肥对退化草地生产力的影响

在科尔沁沙地典型退化草地上开展了裂区组合设计的灌溉与施肥二因素试验。结果表明,科尔沁沙地退化草地土壤储水量受降水量的影响强烈。由于受到干旱气候和灌溉量的影响,灌水仅对地表0~30 cm的土壤含水量变化有作用,对深层土壤的含水量没有作用。灌溉和施肥对沙地退化草地的植物生物量有着明显的促进作用。灌溉处理中,灌溉90 mm试验区的植被生物量为最高(128.3 g/m2),施肥处理中,每hm2施600 kg氮肥试验区的植被生物量为最高(147.3 g/m2)。灌溉90,60,30 mm和对照试验区的植被耗水量分别为379.00,349.90,313.20和293.50 mm。与其相应的水分利用率分别为0.28,0.38,0.34和0.35 kg/(mm.hm2)。综合分析认为科尔沁沙地退化草地的基本耗水量为294 mm。     

A retrospective study of the success of medical and surgical treatment of wild Australian raptors

OBJECTIVE: To evaluate the results of medical and surgical regimens utilised to treat injured and diseased wild Australian raptors presented at our practice, and to determine if the time, effort and cost of treating the birds was justified in terms of the outcomes achieved. PROCEDURE: All the practice's clinical records relating to the examination and treatment of wild raptors were reviewed for the period April 1994 to December 1998. The species of birds, the aetiology of their injuries or diseases, the treatment protocols and the outcomes of those treatments were correlated and tabulated for evaluation. RESULTS: Fifteen Australian species of raptor were examined and treated. Complete records were available for 104 birds of prey, 73 being Accipitriformes and 31 Strigiformes. The poorest prognosis was for birds involved in motor vehicle impacts, while birds suffering malnutrition or starvation had higher survival rates. The overall rate of survival was 50%. CONCLUSION: Based on the severity of diseases and injuries at the time of presentation, the survival rate was considered acceptable. Veterinary involvement in the treatment of the wild raptors was necessary for the maintenance of the birds' welfare, and to determine appropriate treatments. Intangible benefits included increased practice staff satisfaction, and improving the veterinary professions' public image by providing pro bono treatment for Australian wildlife.
