HPLC-PDAD法检测3种中兽药散剂中违规添加4种喹诺酮类药物的研究

为了建立检测中兽药散剂中违规添加氧氟沙星、诺氟沙星、环丙沙星、恩诺沙星4种喹诺酮类药物的反相高效液相色谱法（HPLC-PDAD）,采用Atlantis T3（十八烷基硅烷键合硅胶．4．6min×250mm,5μm）色谱柱,流动相为磷酸溶液：乙腈：甲醇（85．5：7.0：7．5）,流速为1．0mL／min。检测波长为283nm。4种喹诺酮类药物检查方法的线性关系良好,r〉0．9999;回收率均在98．4％～104．6％范围内,RSD均在0．9％～2．3％之间;4种喹诺酮类药物在肥猪散、健胃散、银翘散3种中兽药散剂中的检出限均为200mg／kg。该方法可用于中兽药散剂中违规添加喹诺酮类药物的检测。

发达国家兽医协会的构成与职能

兽医协会早已有之,界定各国兽医协会历史比较困难。兽医协会一般均从兽医学会分立或隶属于兽医学会。兽医协会以会员利益为主体,服务于兽医行业,保护动物福利和健康。协会多由委员会及下属理事会构成。理事会是协会运作的主体,分设各职能分会、部门或机构。协会会员多需要经过正式的学术教育,且通过国家或地方兽医资格考试,有些国家还要求会员是注册兽医。兽医资格考试分为理论考试和临床技能考试。多数国家只需要通过理论考试,有些国家还需要通过临床技能考试。欧美国家还设有专科考试。     

An unholy disease in the Holy Land: The history of anthrax between the Jordan River and the Mediterranean Sea (1909–2012)

The history of recorded cases of anthrax in human beings and animals from 1909 to 2012 in the area between the Jordan River and the Mediterranean Sea is reviewed. The disease was endemic until the middle of the 20th century, but the incidence decreased thereafter, with only sporadic cases from the 1980s onwards. Human cases have not been diagnosed in the region since 1984 and the number of episodes of animal disease has reduced to less than one per year. This decline is mostly due to the disruption of the infective cycle by improved veterinary control, including vaccination, treatment and outbreak management. A policy of reactive vaccination for 10 years of affected herds and herds grazing in their proximity has been applied. No new outbreaks have been observed in such herds after the cessation of vaccination, despite continued grazing on the same sites, so it is assumed that spore survival in such areas is shorter than 10 years. This is independent of the soil composition, which is calcareous throughout most of the relevant area. However, reemergence of anthrax, even after decades, has occurred following disturbance and heavy rainfall.     

PBL模式在兽医影像学课程教学中的应用——以“骨折影像学诊断”教学为例

以扬州大学兽医学院2009和2010级选修兽医影像学课程的学生为研究对象,研究问题引导式教学法在该课程“骨折影像学诊断”教学中的应用效果.结果表明,与基于讲义的教学模式（LBL）相比,采用问题引导式教学方法（PBL）,可显著提高学生的卷面考试成绩、读片考试成绩和病历书写成绩,有助于调动学生的学习积极性,加强学生对知识的掌握程度,提高学生的自主学习能力.

Efficient management of transportation logistics related to animal disease outbreaks

Vehicle routing is a key instrument to manage and control animal disease outbreaks. This paper focuses on an efficient, user-friendly and automatic procedure to manage transportation logistics to and between farms in the case of an outbreak. This procedure can be embedded into a veterinary geographical information system for the management and control of disease outbreaks. The transportation logistics for the problem at hand can be divided into two main transportation categories: (i) round itineraries, which are special cases of the travelling salesman problem, and (ii) one-to-one itineraries. Attention is given to the use of user-friendly, heuristic yet efficient algorithms for the determination of these itineraries. It is furthermore shown that the procedure is developed in such a way that the identified routes meet both national and international regulations in force during disease outbreaks.     

兽药磺胺二甲嘧啶在土壤中的生态行为

通过室内培养和土壤薄层层析等实验方法，研究了磺胺二甲嘧啶对土壤微生物的毒性及其在土壤中的降解、迁移特性。结果显示：在土壤磺胺二甲嘧啶浓度为1mg kg^-1时，土壤中细菌和真菌数量明显减少（p〈0．05），但随时间延长，该抑制作用变缓；磺胺二甲嘧啶在土壤中降解缓慢，持留时间久，在灭菌土和未灭菌土中的半衰期分别为223．9d和102．4d，并容易在土壤中迁移和渗漏，迁移系数R大于0．7，迁移和渗漏速度受介质pH的影响，在非中性环境下，移动和渗漏能力增强。表明磺胺二甲嘧啶是一种在土壤中不易被降解、容易迁移和渗漏到水体、对土壤微生物和水体产生危害的新型污染源。
