Actinomycin D for Reinduction of Remission in Dogs With Resistant Lymphoma     

Anthony S. Moore BVSc  MVSc    Gregory K. Ogilvie  David M. Vail 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1994,8(5):343-344

Twenty-five dogs with malignant lymphoma refractory to chemotherapy were treated with actinomycin D at a median dose of 0.7 mg/m² (range, 0.5 to 0.9 mg/m²) every 3 weeks. The dogs treated had received between 2 and 8 chemotherapeutic agents (median 7), for a median of 266 days before being treated with actinomycin D. For 23 of the 25 dogs, previous chemotherapy included doxorubicin. No dog responded to actinomycin D chemotherapy.  相似文献   

Cardiopathological observation on a case of persistent ventricular tachycardia in a pony mare.     

N Machida  T Nakamura  K Kiryu  S Haramaki  K Too 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》1992,54(6):1213-1216

A 20-year-old pony mare with persistent ventricular tachycardia (VT) was examined cardiopathologically. At necropsy, the heart was enlarged and rounded with both ventricular dilatation. In a longitudinal section of the ventricular septum, a large grayish white patchy lesion (5 x 25 mm) was detected in the relatively higher portion. Microscopically, the lesion was extensive myocardial fibrosis located in the vicinity of the proximal part of the left bundle branch. Partially the fibrotic lesion was in contact with the branch. Such a lesion might play an important role in creating a suitable background for the development of VT via automaticity or reentry mechanism.  相似文献

狗年侃犬     

马大君  方建强  李宝林 《中国工作犬业》2006,(5):37-38

狗年侃犬,犬即是狗,狗即是犬。就字而言,狗是口头语为多,犬是书面语为多。犬与人类的交流与融合,源远流长,这是一个说不完、道不尽的话题。犬的文化也是人们津津乐道的话题,也是一个国家一个民族的文化。我国养犬的历史有几千年,对犬也说法众多,褒贬不一。狗、犬从生物科学来讲都是表述同样的动物,但从中国人文化的内含却有很大的差异。中国人对狗这个字的理解大都含有贬意,民间通俗用语,比较粗糙。对犬的理解似乎有些褒奖与赞美之意,是学术用语,有文化内涵。狗常常是用来形容不好的人或事,是没有教养与没有学问的,人类对它是要进行限制管理…  相似文献

应用反转录—聚合酶链反应(RT-PCR)对猪瘟进行诊断应用研究。应用RT-PCR况对来自广西不同地区的135份疑似猪瘟病料进行检测，以份诊断为阳性，阳性率62．2％。从百色、柳州地区等采集的健康猪扁桃体和淋巴结共276份，经RT-PCR检测，37份为阳性，阳性率为13．4％。其中健康猪扁桃体带毒较高，246份扁桃体中有35份阳性，占14．2％。采自柳州健康猪的26份淋巴结材料全为阴性，只有邕宁县的1份健猪淋巴结阳性。结果表明，RT-PCR技术可应用于猪瘟的临床诊断。  相似文献   

Verification by polymerase chain reaction of vertical transmission of Theileria sergenti in cows   总被引：2，自引：0，他引：2       下载免费PDF全文

Byeong K. Baek  Kim B. Soo  Jin H. Kim  Jin Hur  Bou O. Lee  J. M. Jung  Misao Onuma  Anthony O. Oluoch  Chang-Hyun Kim    Ibulaimu Kakoma 《Canadian journal of veterinary research》2003,67(4):278-282

To evaluate the transplacental transfer of Theileria sergenti infection in cattle, we used DNA probes to detect T. sergenti in 6 pregnant cows and their calves. All the animals were monitored by parasitologic, serologic, and polymerase chain reaction (PCR) assays for a predicted 875-base-pair (bp) DNA product and a 684-bp amplicon detected by nested PCR in the blood and spleens of aborted fetuses. An open reading frame (ORF) starting at nucleotide 170 and terminating at position 1021 was shown to code for a polypeptide of 283 amino acid residues. All 6 dams and 5 calves were positive for T. sergenti in all tests. One calf was positive only with nested PCR. We conclude that transplacental transmission of T. sergenti is a significant problem. The relevance of the data in the programmed introduction of new (especially pregnant) animals into established clean herds needs serious consideration with regard to control of theileriosis and other tickborne diseases.  相似文献

标记抗体染色法检查布氏杆菌的研究     

项光华  文奋武 《甘肃农业大学学报》1990,25(1):95-104

为了建立一种快速、简便、敏感、特异地检测动物病理材料中布氏杆菌的方法,选用四种标记抗体法,对5种共15个生物型的布氏杆菌,以及大量与流产有关或常常污染病理材料的对照细菌,分别进行了纯菌、感染实验动物及牦牛组织材料的染色检查,并与柯氏染色法及细菌分离培养法进行了比较。结果表明,四种方法对于各种材料中的布氏杆菌(粗糙型犬布氏菌除外)均呈阳性反应,而绝大多数对照菌均呈阴性反应。其中尤以SPA法染色背景更为清晰,非特异性反应更少。这些方法既简便、快速,检出率也较高。对于布氏杆菌病的诊断和疫情监测,是很有价值的。  相似文献

Fate of Escherichia coli and Escherichia coli O157 in soils and drainage water following cattle slurry application at 3 sites in southern Scotland

Abstract. Slurry from farm animals may contaminate water supplies, rivers and bathing waters with faecal coliforms, such as Escherichia coli . Where animals harbour the O157 strain the hazard to human health is particularly high, but both the hazard level, and the low incidence and sporadic nature of the excretion of E. coli O157 make it difficult to study this strain under field conditions. The survival of total E. coli and of E. coli O157 were compared in the laboratory for two soils under controlled temperature and moisture. E. coli O157 die-off rate was the same as or quicker than for total E. coli . This result meant that field experiments studying the fate of total E. coli should give a satisfactory evaluation of the risk of water contamination by the O157 strain. In four field experiments at three sites, slurry containing total E. coli numbers of 2.2 × 10⁴ to 5.7 × 10⁵ colony forming units per mL (c.f.u. mL^–1) was applied to drained field plots. Field die-off was faster than expected from laboratory experiments, especially in one experiment where two weeks dry weather followed application. In all but this experiment, the first drain flow events after slurry application led to very high E. coli concentrations in the drains (10³ to 10⁴ c.f.u. mL^–1). E. coli O157 was present in the slurry used for two of the experiments (33 c.f.u. per 100 mL in each case). However the proportion of E.coli O157 was very low (about 1 in 10⁵) and it was not detected in the drainage water. After the first week E. coli drainage water numbers decreased rapidly but they were 1–10 c.f.u. mL^–1 for much of the sampling period after slurry application (1–3 months).  相似文献
