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

心脏体外循环系统检测植物外啡肽活性的研究     

孙镇平  华棣  吕立力  熊万斌  周业飞 《猪业科学》2003,20(7):71-72

本文利用猪胃蛋白酶在37℃条件下降解中筋粉,采集不同反应时间的酶解液样品,低温离心处理后,分别加入蛙心体外循环系统中,测定心肌收缩力变化,并随即加入阿片肽阻断剂-纳洛酮,检测植物外啡肽活性。结果表明,酶解液能够引起心肌收缩力加强,并可被纳洛酮逆转,证明酶解液具有植物外啡肽活性。  相似文献   

不同浓度CO2对牛卵母细胞体外成熟和受精的影响     

朱淑文  华修国  李华威  今野博章  李培昌 《猪业科学》2003,20(9):43-44

对牛卵巢卵泡内卵母细胞在不同浓度的CO2培养箱内体外成熟、体外受精后的卵裂率及胚胎体外发育进行了研究。结果显示,含5%小牛血清(CS)的TCM-199内的卵母细胞在2%CO2条件下培养20h后,达到第二次减数分裂期(MⅡ期)的卵子数明显高于在5%CO2条件下培养的卵母细胞数(P<0.05)。两种浓度的CO2条件下培养的牛卵母细胞体外受精后的卵裂率无明显差异,2%CO2浓度下培养的卵母细胞的囊胚发育率高于5%CO2浓度下培养的卵母细胞。  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
