The clinical and imaging features of four dogs with Cushing's syndrome and pulmonary mineralization are reviewed. Three dogs presented with a primary complaint of respiratory distress/dyspnea. Three dogs had pituitary dependent Cushing's syndrome, while the remaining one dog had iatrogenic Cushing's syndrome. Each dog had clinical features typical for Cushing's syndrome. Two of the dogs were euthanized due to progressive hypoxemia. In each dog, the serum calcium, phosphorous, blood urea nitrogen and creatinine were normal.
A generalized increase in unstructured interstitial pulmonary opacity with diffuse mineralization was noted on thoracic radiographs of all dogs. In one dog, an ill-defined nodular interstitial pattern of mineralization was present. Delayed bone phase scintigraphy using ^99mTechnetium methylene diphosphonate documented generalized pulmonary uptake in two dogs. ^99mTechnetium labeled microaggregated albumin lung perfusion scans were normal in these two dogs. ^99mTc-MDP scintigraphy can provide useful information in diagnosing pulmonary mineralization in Cushingoid dogs.  相似文献   

流行性出血热病毒气溶胶感染乳鼠的免疫病理学研究     

遇秀玲  李劲松 《中国兽医学报》1994,14(2):193-198

采用免疫组化ＢＡ法，对流行性出血热病毒（ＥＨＦＶ）气溶胶感染乳鼠脏器组织中的病毒动态分布进行了观察，并对其抗体消长进行了测定。结果表明：①ＢＡ法为病理诊断ＥＨＦＶ感染提供了一种准确的手段；②ＥＨＦＶ可通过气溶胶途径感染乳小鼠，乳小鼠感染ＥＨＦＶ的ＬＤ５０值可作为环境浓度的参考值；③ＥＨＦＶ气溶胶途径感染乳鼠后，４ｈ即可在心、肺，１ｄ在嗅球部检出，并可在其组织细胞中增殖，经血循、嗅神经、单核巨噬细胞系统等多途径扩散，造成多组织脏器的泛发性感染。感染后１２～１４ｄ，病毒检出率和病毒量均达峰值。动物自身免疫系统对ＥＨＦＶ有一定的清除能力；④感染乳鼠脑、肺、肾等脏器组织的病变与人类感染ＥＨＦＶ的病变有一定的相似性，提示可作为人ＥＨＦＶ的模型动物；⑤抗原检出率高于抗体检出率，ＥＬＩＳＡ法检出率高于ＩＦＡ法检出率。  相似文献   

Recent studies on the enterotropic strain of avian infectious bronchitis virus   总被引：2，自引：0，他引：2  

A. G. Ambali 《Veterinary research communications》1992,16(2):153-157

Avian infectious bronchitis (AIB) is an economically important disease of chickens. Recent studies have revealed enterotropism by at least one strain of AIB virus with pathological lesions in parts of the gut. This review highlights the findings of the studies so far made on this enterotropic strain of AIB virus.  相似文献

将禽白血病病毒 J亚群 (AL V- J)内蒙株 NM876 1和 NM9996人工接种于 1日龄爱维茵肉种鸡 ,通过眼观、病理组织学检查观察了攻毒鸡的病理学特征 ;通过 PCR和 EL ISA技术检测了病毒感染率、抗体变化规律以及病毒和抗体的相关性。结果显示 ,攻毒鸡从第 3周开始即可检出病毒 ,NM876 1株和 NM9996株病毒感染率分别为 71.4 %和6 4 .3% ;从第 5周开始 ,出现较明显的病理学变化 ,病变特征以骨髓、肝脏、心脏、脾、卵巢等组织内髓细胞增生为主 ,而法氏囊、脑、坐骨神经无变化 ;攻毒鸡抗体消长变化有一定的规律 ,一般在 7～ 8周龄和 18～ 2 0周龄时分别出现 1次高峰 ,而在 4～ 6周龄、10周龄和 2 3周龄分别出现 1次低谷 ,提示鸡场进行 EL ISA检测时要避开这一时期 ;攻毒鸡产生耐受性病毒血症 ,即病毒阳性而抗体阴性 (V A- )的比例较高 (7/14 ,9/14 )。通过以上的研究证明 ,AL V- J内蒙株疾病模型复制成功 ,NM876 1、NM9996可作为原型株进行相关研究  相似文献   

不同途径感染猪血球凝集性脑脊髓炎病毒的比较病理学   总被引：6，自引：0，他引：6

用传代鼠血球凝集性脑脊髓炎病毒接种液，经不同途径感染12头5日龄仔猪作比较病理学研究。结果表明，经脑内注射、前后肢肌肉注射、口服、口服兼滴鼻等途径接种的仔猪全部感染发病，并在接种后36～98h死亡。发病猪出现脑、脊髓的小静脉和毛细管充血、出血、水肿，神经原水肿、急性肿胀、急性液化及中央染色质溶解，胶质细胞轻微增生等非化脓性脑脊髓炎特征。口服兼滴鼻接种猪脑脊髓出血、脑水肿最明显，神经原变质也最重。脑内接种猪脑膜的血管周围出现明显的免疫细胞反应。  相似文献   

The influence of fasting on blood glucose,triglycerides, cholesterol,and alkaline phosphatase in rats     

Waner T  Nyska A 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1994,23(3):78-80

Serum concentrations of glucose, cholesterol, triglycerides, and serum alkaline phosphatase activity were measured over different periods of time of food deprivation in male rats. Thirty percent of non-fasted rat's sera was found to be lipemic. At 16 hours of fasting, glucose levels dropped by 30% compared to the level of the non-fasting control group, and remained at a relatively constant level for up to 48 hours of fasting. Triglyceride concentrations decreased at 16 hours after fasting. Serum cholesterol levels were not changed at any of the fasting periods compared to the non-fasted control group. Alkaline phosphatase activity was decreased at 8 hours of fasting, with further declines in activity of the serum enzyme seen at 16, 24, and 48 hours of fasting. It was concluded that at 16 to 18 hours fasting, a non-absorptive state had been reached in male rats.  相似文献   

Pathogenicity and Virulence of the Two Dutch VCGs of Verticillium dahliae to Woody Ornamentals     

J.C. Goud  A.J. Termorshuizen 《European journal of plant pathology / European Foundation for Plant Pathology》2002,108(8):771-782

Two experiments were performed in two consecutive years to test whether isolates of different vegetative compatibility groups (VCGs) differ in their ability to cause disease in woody ornamentals, to study the host specificity of the isolates and to get an insight into disease development in woody hosts. A range of woody ornamental plant species, including Acer campestre, Acer platanoides, Acer pseudoplatanus, Catalpa bignonioides, Cotinus coggygria, Robinia pseudoacacia, Rosa canina, Syringa vulgaris and Tilia cordata, were root-dip inoculated with six isolates of Verticillium dahliae, belonging to the two VCGs that occur in the Netherlands (VCG NL-1 and VCG NL-2). Isolates belonging to each VCG caused severe symptoms of verticillium wilt in most plant species tested. Disease progress differed between plant species, but was generally the same for the two VCGs. No overall differences in virulence were observed between the two VCGs for external wilt symptoms, number of dead plants, or shoot length. No significant VCG × plant species interactions were present for these characteristics. However, isolates of VCG NL-1 caused more vascular discolouration than did isolates of VCG NL-2. Isolates within VCGs often differed considerably in their virulence to certain hosts, as shown by highly significant isolate × plant species interactions. Isolates were more virulent on their original host. These findings imply that VCG identification does not contribute to disease prediction for a range of woody hosts.  相似文献

Lactation-related mammary gland pathologies—A neglected emergency in the bitch     

Iosif Vasiu  Roman Dąbrowski  Asta Tvarijonaviciute 《Reproduction in domestic animals》2021,56(2):208-230

Mastitis is a common reproductive disorder in bitches, reaching a prevalence of 0.71%. Mastitis has a wide range of forms, from asymptomatic to severe gangrenous mastitis that can lead to septic shock and death of the bitch and nurslings. However, most of the time it is overlooked, undiagnosed or mistreated. The present systematic review was performed to revise and summarize the existing knowledge related to this disorder, including diagnosis, treatment and prevention.  相似文献
