奶牛产后截瘫病例的诊治

产后截瘫,是奶牛分娩后出现躺卧、后躯不能起立的一种疾病。 2004年到2007年,笔者共治疗奶牛产后截瘫病牛19例,其中头胎奶牛4例、三胎奶牛3例、四胎奶牛5例、五胎以上奶牛7例。治愈16例,未治愈而淘汰3例,治愈率为84.2%。其中1d治愈7头,2d治愈及3～5d治愈的各有4头,10d以上治愈1头。     

一起奶牛产前截瘫症的治疗

奶牛的产前截瘫多发于3～5胎怀孕中、后期的怀孕母牛和年老、衰弱、营养不均衡的怀孕母牛,主要是患牛血中钙、磷浓度急剧下降引起的运动机能障碍的一种疾病;此病的主要特点是患牛病初不能久站、交替踏步、最后发展到全身无力、卧地不起、口无烂苹果味、不昏睡、有强烈的站立意识。     

犬木糖醇中毒的研究进展

木糖醇是一种天然的五碳糖醇,在自然界中分布范围广,在各种水果和蔬菜等中存在,常作为甜味剂用于无糖的糖果和口香糖、甜点、饮料和牙膏等中。木糖醇虽对绝大部分哺乳动物安全性高,但对犬类却具有致命的毒性作用。犬摄入超过0.1 g/kg的木糖醇会有低血糖的风险,摄入超过0.5 g/kg可能产生肝毒性,会危及生命且木糖醇中毒无特效解毒剂。由于人类消费木糖醇各种产品的扩大以及宠物产业的发展,使得犬类接触木糖醇并引起中毒的几率大大增加。本研究主要从犬木糖醇中毒的毒代动力学、临床症状与病理变化及救治和检测等方面予以综述,以期引起重视并为中毒的预防和救治提供参考。     

Ketamine in dogs

The cardiopulmonary consequences of ketamine (10 mg/kg, IV) were evaluated in 18 dogs. Heart rate, cardiac output, systemic blood pressure, left ventricular work, oxygen transport, oxygen consumption, carbon dioxide production, and core temperature increased. Breathing rate, minute ventilation, and arterial partial pressure of oxygen transiently decreased. Arterial partial pressure of carbon dioxide, alveolar-arterial oxygen gradient, and venous admixture transiently increased. The duration of action of ketamine for surgical anesthesia was short. Muscle tone and salivation were excessive, and spontaneous muscular activity was prominent.     

Panosteitis in dogs

The clinical and radiographic signs of panosteitis in seven dogs are described and also the histological and fluorochrome-labelled appearance of the lesions in one of them. The condition was seen in three immature German Shepherd dogs, three immature mongrels, of which two were littermates, and an adult Doberman Pinscher which presented with lesions of its metacarpus.
