A METHOD OF MOUNTING A GAMMA DETECTOR AND YOKE ASSEMBLY FOR EQUINE NUCLEAR IMAGING

A scintillation detector assembly capable of providing the range of movement and flexibility needed for the investigation and diagnosis of equine-related health problems was required for the nuclear medicine facility of the Equine Research Centre, Guelph, Ontario. The planning, technique and modifications used to mount the gamma detector and yoke assembly are detailed herein. The system has been successfully used for the nuclear scans in horses, and demonstrates the practicality, safety and usefulness of equipment adaptation for large animal imaging.     

COMPARATIVE STUDY OF INDIUM-111 LEUKOCYTES AND NEPHROSONOGRAPHY FOR DETECTION OF EXPERIMENTAL PYELONEPHRITIS IN DOGS

Nephrosonography was compared to In-111 WBC for detection of experimentally induced pyelonephritis in 12 dogs. Nephrosonography was performed during the acute and chronic phase of pyelonephritis in all dogs. Sonographic abnormalities were found in all infected kidneys imaged early after infection. In the chronic phase of pyelonephritis, the sonographic abnormalities had decreased in severity in 9 kidneys, increased in severity in 2 kidneys, and had resolved in 2 kidneys. After histopathologic evaluation, eleven of fifteen kidneys (73%) with pyelonephritis had been identified by sonography. The In-111 WBC scan was performed during the acute phase of pyelonephritis in 9 dogs and during the chronic phase in all dogs. During the acute phase of pyelonephritis, the WBC scan was positive in 8 of the 9 dogs (89%) on images acquired 24 and 48 hr after injection of the labelled WBC. During the chronic phase of pyelonephritis, the WBC scan was negative in all 12 dogs. The sensitivity of the In-111 WBC scan was poor compared to nephrosonography for detection of chronic pyelonephritis. In this study, optimal detection of renal infection/pyelonephritis by In-111 WBC may be dependent on the presence of clinical signs and leukocytosis in dogs. Even when leukocytosis is present, the In-111 WBC may fail to accumulate in the kidney in dogs with pyelonephritis, particularly if no clinical signs (fever, depression, inappetence) are present.     

“棘防A号”的安全性评价

90只小白鼠随机分为9组，每组10只，除对照组外，其余8组分别以绵羊每日正常用药量的1．5n等比级数递增剂量，一次给小白鼠灌服“棘防A号”，连续观察14d，以测定“棘防A号”对小白鼠口服的LD50。结果表明，当小白鼠用绵羊正常用药量的11倍时，不出现半数死亡，说明“棘防A号”对小白鼠的LD50大于绵羊正常用药量的10倍。是安全性的药物。     

山东省部分地区鸡大肠杆菌的菌株分离与耐药性分析

对来自山东省部分发病区的10株鸡大肠杆菌分离株,按Kirby-Bauer法(纸片扩散法)进行了药敏试验研究。结果表明,丁胺卡那霉素、卡那霉素、新霉素、庆大霉素等对鸡大肠杆菌为最佳高敏药。     

从英国皇家兽医学院办学模式看中国兽医人才培养

英国伦敦大学皇家兽医学院以其独具魅力的校园风格、合理的学科机构设置、务实创新的教学科研风气、严格的竞争管理机制、产学研结合的办学思路等,给我们以众多启示。中国兽医专业办学应以特色优势立校,明确培养目标和配套措施,尽快与国际兽医高等教育接轨,促进创新性兽医人才的培养。     

水族的传统农耕文化

孕育于百越母体中的水族稻作农业文明,在水族迁居黔桂边境之后,通过适时的文化调适,不但延续了原先“火耕水耨”的文化传统,更创造了“畲山为田”的梯田开发模式,劳动生产工具和耕作技术体现了历史上他们与百越民族(骆越)的渊源关系,对历史的共同追忆,使人们打破了时空界线,形成了强烈的文化认同感和归属感。

中西兽医结合治疗水牛衰竭症的疗效分析

水牛衰竭症是信阳地区危害较大的一种内科病。过去临床上治疗比较混乱,治愈率低下,笔者就多年来经历的61例病牛的治疗方法与疗效进行了对比,结果表明中西兽医结合治疗的治愈率明显高于单一的中医或西医治疗,治疗时间也相应缩短。
