RESUMENEl objetivo de este estudio fue proporcionar una descripción detallada de la anatomía normal del cerebro de potrillos neonatos y de las estructuras asociadas mediante tomografía computarizada (TC) y cortes anatómicos. Se utilizó un escáner de cuarta generación y se adquirieron imágenes transversales con un grosor de dos milímetros. Tras el estudio por TC, los animales fueron sacrificados por razones no relacionadas con patologías de la cabeza. Para ayudar en la identificación precisa del cerebro y las estructuras asociadas, las imágenes de TC fueron comparadas con las correspondientes secciones de la cabeza. Las imágenes de TC se correlacionaron de buena manera con sus correspondientes secciones anatómicas, mostrando una buena diferenciación entre el tejido óseo y el tejido blando de la cabeza. Las imágenes obtenidas mediante TC pretenden ser una referencia anatómica inicial para la interpretación de los estudios clínicos del cerebro y las estructuras asociadas en potros vivos recién nacidos.Palabras clave: tomografía computarizada, anatomía, cerebro, potro neonato. SUMMARYThe aim of this study was to provide a more complete description of normal cross-sectional anatomy of the neonatal brain of the foal and associated structures by computed tomography (CT) and gross anatomical sections. Using a fourth-generation CT scanner, 2-mm contiguous transverse images were acquired from two neonatal 5-days-old Quarter horse foals. After the study the animals were euthanised for reasons unrelated to head pathology. To assist in the accurate identification of brain and associated structures, transverse CT images were obtained and compared with the corresponding frozen cross-sections of the head. CT images matched well with their corresponding transverse gross sections and provided good differentiation between the bones and the soft tissues of the head. These CT images are intended to be a useful initial anatomic reference in the interpretation for clinical CT imaging studies of the brain and associated structures in live neonatal foals.
The purpose of this paper was to study the possible causes of Non-Specific Reactive Hepatitis (NSRH) in tissue samples of housed dogs that were collected from different cities of Andalucia (Spain). Histologically, this disease was characterized by the presence of lymphocytes and plasma cells spread throughout the liver parenchyma and in the portal stroma, with no evidence of hepatocyte necrosis. These animals showed non-specific chronic reactive hepatitis that varied from moderate to severe. In order of prevalence, the more common pathologies associated with NSRH were gastrointestinal and renal diseases, as well as pneumonia mainly of parasitic or infectious origin. ÖzBu çalışmanın amacı, Endülüs'ün (İspanya) farklı şehirlerinden toplanmış olan barınak köpeklerine ait doku örneklerinde Spesifik Olmayan Reaktif Hepatitin (NSRH) olası nedenlerini araştırmaktı. Hastalık, histolojik olarak, hepatosit nekrozu bulgusu olmadan, karaciğer parankimi boyunca ve portal stroma içinde yayılan lenfositlerin ve plazma hücrelerinin varlığı ile karakterize edildi. İncelenen hayvanlarda, derecesi orta ila şiddetli arasında değişen, spesifik olmayan kronik reaktif hepatit belirlendi. Görülme oranı yönünden değerlendirildiğinde, NSRH ile ilişkili olarak en sık görülen patolojiler gastrointestinal problemler ve böbrek hastalıklarının yanı sıra parazitik veya bulaşıcı kökenli pnömonilerdi.

The aim of this study was to describe the gross, histopathological and immunohistochemical features of non-specific reactive hepatitis (NSRH) in stray dogs. To perform this study the livers of 23 dogs of different breed and sex were used. The tissue sections were stained with hematoxylin–eosin, and immunohistochemically. The results of this work showed that NSRH was characterized by the infiltration of lymphocytes and plasma cells scattered throughout the liver parenchyma and in the portal stroma, and associated with inflammatory and non-inflammatory diseases in other organ systems. The inflammatory infiltrate of NSRH was composed of CD3+ T lymphocytes and HLA-DR+ lymphocytes, as well as IgG+ plasma cells and alpha-1-antitrypsin+ macrophages in the portal spaces and hepatic sinusoids.
This paper evaluates possible relations between the clinical activity and the histopathological findings of the entire intestine in dogs with inflammatory bowel disease (IBD). To perform this study, hospital records of 64 dogs of different sex and breed diagnosed with IBD were evaluated. The results of this study did not show a statistically significant correlation between clinical activity and the histopathological assessment of dogs with IBD. Certain connections were found between diarrhea and lacteal dilation in duodenum, and hematochezia and villous epithelial injury in colon but no other associations were found between the rest of the lesions and symptoms.
