Ocular absorption and toxicity of methotrexate in the dog          下载免费PDF全文

Bussanich MN  Rootman J  Kumi C  Gudauskas G 《The Canadian veterinary journal. La revue veterinaire canadienne》1985,26(9):263-266

The ocular absorption, elimination and toxicity of 12.5 mg of methotrexate in 0.5 cc administered subconjunctivally was studied in the dog. The purpose of this study was to establish ocular pharmacokinetics for treatment of intraocular tumours in dogs. Drug levels were measured in ocular compartments, and serum at 1,2,4,6,8 and 12 hours respectively. Tumoricidal concentrations of the drug were attained in the anterior chambers of the injected eyes up to and including six hours postinjection. Consistent signs of toxicity were anorexia, vomiting, weight loss and leukopenia. Local ocular toxicity following subconjunctival injection was minimal conjunctival hyperemia lasting up to 48 hours.  相似文献   

Evaluation of a Killed Vaccine Against Porcine Pleuropneumonia Due to Haemophilus pleuropneumoniae   总被引：20，自引：2，他引：18  

Higgins R  Larivière S  Mittal KR  Martineau GP  Rousseau P  Cameron J 《The Canadian veterinary journal. La revue veterinaire canadienne》1985,26(2):86-89

A bacterin containing serotypes 1 and 5 of Haemophilus pleuropneumoniae was developed for the prevention and the control of porcine pleuropneumonia. It was injected intramuscularly into three groups of ten piglets, the first group with one dose, the second one with two doses and the third one with three doses at two-week intervals. Another group of ten piglets did not receive the vaccine. All the piglets were then challenged by an aerosol of mixed suspensions of H. pleuropneumoniae serotypes 1 and 5. Two and three injections of vaccine completely prevented mortality, whereas half of the control piglets and of those receiving only one dose of vaccine died. All surviving piglets, both control and vaccinated, had severe signs of respiratory disease for at least 36 hours after exposure to challenge. Moreover, vaccination did not induce the production of antibodies at high titers. Local reactions were not noted after vaccination and at postmortem; ten weeks after the challenge, there were no signs of abscess formation or induration.  相似文献

利用生化分析鉴别柑桔杂种苗和珠心苗     

Ortiz  J.M.  王定祥 《浙江柑橘》1985,(2)

珠心胚(苗)是柑桔育种过程中的一个主要障碍。作者利用30年生(人工授粉时)的"Verna"柠檬与酸橙杂交获得33株实生苗,在温室中长到第三年时取成熟和健康叶片进行生化分析。结果表明:总蛋白用SDS一聚丙烯酰胺凝胶平板电泳共得到35条以上的谱带,杂种苗与珠心苗间的谱带数没有差异,仅从扫描图上发现某些带有定量(扫描峰高)差异;它们的第4条带(扫描峰)比任何一个亲本高,可能与树龄及生理年龄不  相似文献
