Abstract— Epidermotropic cutaneous T-cell lymphoma was diagnosed in six Syrian hamsters (Mesocricetus auratus) with a generalised dermatosis characterised by pruritus, alopecia and exfoliative erythroderma. Plaques and nodules were evident in one animal. Clinical and histopathological findings were suggestive of mycosis fungoides and electron microscopical investigations in one case were supportive. Immuno-histochemical stains for CD3 antigen were strongly positive in all cases. Résumé— Un lyphome T cutané a été diagnostiqué chez six hamsters de Sibérie (Mesocricetus auratus) avec une dermatose généralisée, caractérisée par un prurit, une alopécle et une érythrodermie exfoliative. Des plaques et des nodules ont été observées sur un animal. Les données cliniques et histopathologiques étaient évocatrices d'un mycosis fungoïdes et les examens en microscopie électronique étaient compatibles dans un cas. Les marquages immuno-histochimiques de l'antigène CD3 étaient très positifs dans tous les cas. Zusammenfassung— Bei sechs Syrischen Goldhamstern (Mesocricetus auratus) wurde ein epidermotropes kutanes T-Zell-Lymphom mit einer generalisierten Dermatose diagnostiziert, die durch Pruritus, Alopezie und eine exfoliative Erythrodermie gekennzeichnet war. Bei einem Tier traten auch Plagues und Knoten auf. Die klinischen und histopathologischen Befunde deuteten auf Mycosis fungoides hin. Elektronenmikroskopische Untersuchungen unterstützten diesen Verdacht in einem Fall. Immunhistochemische Färbungen auf CD3-Antigen waren bei alien Fallen stark positiv. Resumen En un grupo de seis hamsters de siria, (Mesocricetus auratus), se diagnosticó limfoma epidermotrópico cutáneo de linfocitos T, presentando una dermatosis generalizada de tipo pruriginoso, acompañada de alopecia y eritroderma exfoliativo. Las placas y nódulos fueron evidentes en uno de los animales. Los estudios clinicos e histopatológicos indicaron una micosis fungoide, y las investigaciones de microscopía, en uno de los caseos, pareció indicar lo mismo. La tintura inmuno-histoquimica para el antígeno CD3 resultó claramente positiva en todod los casos. 相似文献

Background
Canine cutaneous T‐cell lymphoma (CTCL) is an uncommon disease for which efficacious therapies are lacking. The novel anticancer nucleotide prodrug VDC‐1101 (formerly known as GS‐9219) has shown efficacy in dogs with multicentric lymphoma. One of the observed adverse effects with this drug was a skin change characterized by hair loss, erythema, and pruritus, implying delivery of VDC‐1101 to the skin.Hypothesis/Objectives
The primary study objective was to identify the objective response rate (ORR) to VDC‐1101 in canine CTCL; secondary objectives included characterization of progression‐free survival (PFS) and adverse events (AEs).Animals
Twelve dogs with chemotherapy‐naïve or relapsed, histologically and immunohistochemically confirmed CTCL.Methods
Dogs received VDC‐1101 as a 30‐minute IV infusion once every 21 days. Prednisone (1 mg/kg PO q48h) was administered concurrently.Results
In 11 evaluable patients, responses included 1 complete response (CR), 4 partial responses (PR), 2 stable disease (SD), and 4 progressive disease for an ORR of 45% and biologic response rate (CR/PR/SD) of 64%. The median PFS was 37.5 days (26 to >399 days), which includes 1 durable and ongoing CR (>1 year). Gastrointestinal and hematologic AEs were mild; no dogs developed grade 3 or 4 AEs. Three dogs developed dermatopathies and 1 of these dogs was removed from the study as a result of this AE.Conclusions and Clinical Importance
VDC‐1101 has activity against canine CTCL and could provide another treatment option in a disease process with a poor prognosis. 相似文献6.
家蚕灰僵病病原的鉴定 总被引：2，自引：0，他引：2
家蚕灰僵病(grey muscardine)是一类不常见的真菌病,其病原一直未能确定。从感染灰僵病的家蚕体中分离获得一株棒束孢(Isaria),菌株编号为RCEF197,测定了该菌株的ITS1-5.8S-ITS2 rDNA区域序列,研究了该菌株的菌落和显微形态特征。与一些近似的棒束孢和拟青霉(Paecilomyces)的ITS序列进行比较,该菌株和爪哇棒束孢菌株CBS134.22的相似性为99.8%,在构建的棒束孢属部分种的系统发育树中,该菌株与爪哇棒束孢聚为一类,再结合该菌株具有的淡灰紫色菌落和长椭圆形分生孢子大小等形态学特征,将家蚕灰僵病的病原确定为爪哇棒束孢Isaria javanica。 相似文献

蜂胶对雏鸡霉菌病的疗效观察 总被引：1，自引：0，他引：1
本实验用20%蜂胶乙醇浸液,1.5ml/只（含蜂胶0.3g)拌人日粮挥干乙醇,治疗300例（自然感染200例,人工复制100例）感染曲霉病,毛霉病的3日龄雏鸡,5d为1个疗程,连用3个疗程,治愈率为80%-82%,与1/2000硫酸铜饮水,2万单位/只制霉菌素治疗组（82%）相比,疗效相近,蜂胶治疗组雏鸡死亡率为18%-20%,与不用药治疗的对照组雏鸡死亡率（70%）差异极显著,因此认为,蜂胶将是一种抗霉菌新药,蜂胶除有广谱抗真菌作用外,对致病细菌,病毒和原虫也有广谱杀菌和抑菌作用,它又是一种抗霉菌新药,蜂胶除有广谱抗真菌作用外,对致病细菌,病毒和原虫也有广谱杀菌和抑菌作用,它又是一种天然免疫刺激剂,有广泛的生物活性作用,将成为兽医临床应用前景广阔的天然药物。 相似文献

This retrospective study examined the use of CCNU (1-[2-chloroethyl]3-cyclohexyl-1-nitrosurea) in 36 dogs with epitheliotropic lymphoma. Thirty-one (86%) dogs had the cutaneous form of disease, and 5 (14%) dogs had the oral form of disease. Nineteen (51%) dogs were treated with other chemotherapeutic agents before receiving CCNU. All dogs had detectable disease at the time CCNU therapy was initiated. Dogs received a median starting CCNU dosage of 70 mg/m2 (range, 50-100 mg/m2). The median number of treatments administered was 3 (range, 1-12 treatments). After the initial treatment, the CCNU dosage was adjusted in 9 of 26 (35%) dogs in which CCNU was continued: 7 had dosage reductions, and 2 had dosage escalations. Twenty-eight of 36 (78%) dogs had a measurable response to CCNU for a median duration of 106 days (95% confidence interval [CI], 75-182). Six dogs (17%) had a complete response, including 5 dogs with the cutaneous form and 1 dog with the oral form. Twenty-two dogs (61%) had a partial response, including 20 dogs with the cutaneous form and 2 dogs with the oral form, for a median duration of 88 days (95% CI, 62-170). Toxicoses after CCNU chemotherapy included myelosuppression in up to 29% of the dogs, gastrointestinal signs in up to 22% of the dogs, and liver enzyme activity increases in up to 86% of the dogs. This study demonstrates that CCNU chemotherapy can be considered a reasonable option for the treatment of canine epitheliotropic lymphoma in dogs. 相似文献

以家蚕真菌病病原为受试菌,对抗真菌药物氟康唑(FCZ)和盐酸特比萘芬(TBF·HCl)进行了体外筛选,研究了盐酸特比萘芬对家蚕真菌病的防治效果及其稳定性。试验结果表明,盐酸特比萘芬的体外抑菌、杀菌效果优于氟康唑,盐酸特比萘芬对家蚕病原真菌的最小抑菌浓度范围为0.0625～0.2726μg/mL,最小杀菌浓度范围为0.125～4μg/mL。生物试验表明,盐酸特比萘芬对家蚕真菌病防治效果良好,200μg/mL时防治效果达100%,且对家蚕生长发育、茧质无不良影响。稳定性试验表明盐酸特比萘芬长期稳定性良好。 相似文献
