Computed Tomography and Magnetic Resonance Imaging of an Epidermoid Cyst in a Foot of a Horse     

《Journal of Equine Veterinary Science》2020

An 18-year-old Quarter Horse mare was evaluated because of moderate left forelimb lameness of 4 weeks’ duration. The clinical evaluation and diagnostic perineural analgesia localized the lameness to the distal portion of the left forelimb. There was swelling on the dorsal and lateral aspect of the coronary band. Radiography, ultrasound, magnetic resonance imaging, and computed tomography of the foot revealed circumscribed well-capsulated soft tissue mass causing a focal deformation of the dorsolateral border of the middle phalanx. The treatment aimed to remove the mass surgically and stabilized the interphalangeal joint, but the owner elected human euthanasia before treatment attempt. Histopathology diagnosis was an epidermoid cyst, which was characterized by multilayers of keratin surrounded by stratified squamous epithelium. Although rare, an epidermoid cyst should be considered as a differential diagnosis for space-occupying mass in horses’ foot that develops chronic lameness after trauma. This report describes the multimodality appearance of the epidermoid cyst.  相似文献   

Follicular Dysplasia in Adult Black and Red Doberman Pinschers     

WILLIAM H. MILLER Jr. 《Veterinary dermatology》1990,1(4):181-187

Abstract— Four black and two red Doberman Pinschers with a slowly progressive, dorsal hypotrichosis were studied. All six dogs developed the hair loss as adults and hypotrichosis was permanent. Skin biopsies showed changes compatible with follicular dysplasia.
Résumé— L'etude porte sur 4 Dobermans noirs et 2 Dobermans marrons présentant une hypotrichose dorsale d'extension progressive. L'hypotrichose dorsale d'extension progressive. L'hypotrichose s'est développée chez les 6 chiens à l'âge adulte et est permanente. Les biopsies cutanées ont montré des images compatibles avec le diagnostic de dysplasie folliculaire.
Zusammenfassung— Bei vier schwarzen und zwei roten Dobermännern wurde eine langsam fortschreitende dorsale Hypotrichose festgestellt. Alle 6 Hunde verloren als adulte Tiere permanent Haare. Die histologischen Untersuchungen zeigten Veränderungen, die einer Follikeldysplasie entsprechen.
Resumen  Se describe la presencia de una hipotricosis dorsal de progresión lenta en cuatro perros de raza Doberman color negro y dos perros de raza Doberman y color rojo. En los seis animales la hipotricosis se inició cuando eran adultos y se mantuvo de forma permanente. Las biopsias cutáneas mostraron cambios histopatológicos compatibles con una displasia folicular.  相似文献   

Accessory corpora lutea formation in pregnant Hokkaido sika deer (Cervus nippon yesoensis) investigated by examination of ovarian dynamics and steroid hormone concentrations

Generally, sika deer conceive a single fetus, but approximately 80% of pregnant females have two corpora lutea (CLs). The function of the accessory CL (ACL) is unknown; moreover, the process of ACL formation is unclear, and understanding this is necessary to know its role. To elucidate the process of ACL formation, the ovarian dynamics of six adult Hokkaido sika deer females were examined ultrasonographically together with peripheral estradiol-17β and progesterone concentrations. ACLs formed in three females that conceived at the first estrus of the breeding season, but not in those females that conceived at the second estrus. After copulation, postconception ovulation of the dominant follicle of the first wave is induced by an increase in estradiol-17β, which leads to formation of an ACL. A relatively low concentration of progesterone after the first estrus of the breeding season is considered to be responsible for the increase in estradiol-17β after copulation.  相似文献

宋维龙  胡晓青  华启云  高士寅 《畜禽业》2007,(10):76-79

卵泡闭锁是雌性动物重要的生理过程。细胞因子(IGFs、FGF、EGF、TNF、TGF和PA等)可单因素或多因素的参与卵泡闭锁的调节。本文着重介绍了细胞因子对卵泡闭锁的调控方面的最新研究进展。  相似文献   

牛卵母细胞体外成熟技术研究     

贺奋义  桑国俊  余四九  郭海龙  豆有院  邱忠玉  丁春贤  王珂 《畜牧兽医杂志》2008,27(6)

从两方面探讨了牛卵母细胞的体外成熟培养效果,即对不同级别和不同卵巢卵泡直径的卵丘卵母细胞复合体（COCs）进行成熟培养,测定其成熟率。COCs级别不同,培养成熟率之间存在很大差异,A级COCs成熟率为63．81％,B级为47．81％,显著高于C级和D级（P〈0．01）。卵母细胞的成熟率与采集COCs时的卵泡直径关系密切。中等卵泡的卵母细胞的成熟率为61．82％,显著高于小卵泡和大卵泡（P〈0．01）。试验结果表明：A级和B级COCs是卵母细胞体外培养的主要资源;在卵母细胞体外培养过程中,宜选择卵泡发育水平基本正常的中等卵泡采集COCs,而不宜选择发育过大或过小的卵泡。  相似文献

我们自１９９６年１月至１９９８年１０月对黑龙江省八五一一农场和八五六农场４６头患有卵泡囊肿的奶牛进行了４种治疗方法的对比试验,试验结果表明：大剂量ＨＣＧ静脉注射组（１２／１５）效果优于ＨＣＧ肌肉注射２０００单位组（４／９）、肌注ＬＨＲ２０００微克组（８／１２）和ＬＨ肌注２００单位组（６／１０）。  相似文献   

血管生长调节因子与卵巢发育的关系     

时小艳 《西北农业学报》2016,25(12):1755-1761

旨在探讨血管内皮生长因子(VEGF-120)、促卵泡激素(FSH)、2-甲氧基雌二醇(2-ME2)、4-羟基雌二醇(4-OHE2)对卵泡生成的影响。通过对比试验,将试验组分别腹腔注射上述4种药品,一段时间后,HE染色统计分析卵巢中不同大小卵泡数量的变化、卵泡周围血管发育情况及定量分析VEGF、FLK-1表达情况。结果表明,VEGF-120组和FSH组大卵泡数增加,血管发育良好,VEGF和FLK-1基因表达增加;2-ME2和4-OHE2组大卵泡数减少,血管发育情况较差。综合分析发现,血管簇发育良好的卵泡生长状态良好,卵泡的生长与血管的发育存在一定关联。  相似文献   

水牛卵泡液中雌二醇和睾酮水平变化的初步研究     

刘继龙  曹思钦  王慧英  谭世俭 《黑龙江畜牧兽医》2009,(7)

试验采用ELISA法对离体水牛卵巢不同大小卵泡液中的雌二醇(E2)和睾酮(T3)水平进行了定量分析.结果表明:较大卵泡(直径≥6 mm)液中雌二醇的平均浓度是中小卵泡(直径为2～5 mm)液中的8.5倍;而中小卵泡液中睾酮的平均浓度则是较大卵泡液中的3.3倍;较大卵泡液中雌二醇与睾酮比值显著高于中小卵泡.试验结果说明高浓度的雌激素对卵泡的发育有促进作用,而高浓度的雄激素则发挥抑制作用.  相似文献   

Multiple molecular forms of inhibin in buffalo (Bubalus bubalis) ovarian follicular fluid     

Anita Ganguly  Sanat K. Meur 《Research in veterinary science》2010,89(1):14-19

Inhibin is a heterodimeric glycoprotein hormone involved in the regulation of FSH release from the anterior pituitary gland and it has been characterized from various animals. Although, multiple molecular forms of inhibin have been reported from different species, however, the molecular nature of inhibin has not been studied in buffaloes. In the present study, attempts were made to identify inhibin in buffalo ovarian follicular fluid. Buffalo ovaries were obtained from the local abattoir and follicular fluid was aspirated from surface follicle (with diameter ?5 mm). A combination of techniques (viz., gel filtration, SDS-PAGE, Western blot etc.) was employed for identification and isolation of inhibin(s). Inhibin bands were detected at 129 and 63 kDa by Western blot analysis in non-reducing conditions. In reduced SDS-PAGE, 63 kDa fraction produced a single band while 129 kDa fraction resolved into four components of 63, 43, 29 and 20 kDa. Out of them only 29, 63 and the native 129 kDa fractions produced bands on Western blot analysis. In total five fractions (63, 54, 39, 29, 25 kDa) were obtained by trypsin digestion of 129 kDa form. However, only 63 and 29 kDa fractions showed immunoreactivity. In this study, for the first time, we have identified two major forms of inhibin (129 and 63 kDa) with little proteolytic cleavage/processing of the large precursor in the buffalo follicular fluid.  相似文献

在成熟液中添加不同处理及来源的牛卵泡液(bFF),以研究其对延边黄牛卵母细胞体外成熟及重组胚发育的影响。结果表明:未抽滤组与抽滤组间成熟率差异不显著(P>0.05),但未抽滤组显著提高囊胚率(P<0.05);卵泡直径2~8 mm组、>8 mm组和混合组(2~8 mm组与>8 mm组的混合)之间成熟率、卵裂率和囊胚发育率差异不显著(P>0.05);两试验组(黄体组、卵泡组)成熟率、卵裂率和囊胚率差异不显著(P>0.05),两试验组与血清组相比囊胚率显著提高(P<0.05)。试验结果提示,未抽滤黄体期卵巢表面卵泡内bFF能有效提高卵母细胞体外囊胚发育率。  相似文献
