RESUMO
A histerocele é uma condição rara na espécie felina, sendo caracterizada por protrusão do útero pelo anel inguinal. O diagnóstico diferencial inclui tumor mamário, linfadenopatia, hematoma, abscesso e granuloma. Assim, exames de imagem como a ultrassonografia abdominal apresentam importante papel no diagnóstico e prognóstico da doença. O tratamento dessa condição é cirúrgico e inclui a realização de herniorrafia e ovário-histerectomia, a fim de evitar recidivas e a transmissão hereditária. O presente trabalho relata um caso de uma gata adulta com aumento de volume inguinal. Ao exame ultrassonográfico foi identificada a presença de útero herniado, contendo três fetos viáveis. O tratamento consistiu em cesariana, ovário-histerectomia e herniorrafia pela via inguinal.(AU)
Hysterocele is a rare condition in the feline species, characterized by a protrusion of the uterus through the inguinal ring. Differential diagnoses include mammary tumors, lymphadenopathy, hematoma, abscess and granuloma. Thus, imaging tests such as abdominal ultrasound play an important role in the diagnosis and prognosis of the disease. The treatment of this condition is surgical and includes the performance of herniorrhaphy and ovariohysterectomy, in order to avoid recurrences and hereditary transmission. The present study reports a case of an adult cat with increased inguinal volume. The ultrasound examination identified the presence of a herniated uterus, containing three viable fetuses. Treatment consisted of cesarean section, ovariohysterectomy and inguinal herniorrhaphy.(AU)

Spix's Yellow-toothed Cavy is a histrichomorphic rodent of the Caviidae family found in South American countries such as Brazil and Bolivia. It is a widely-used species as an experimental model in research in reproductive biology due to morphological and reproductive characteristics, such as the similarity in the placental development of Galea spixii and human species. However, there are no studies on the behavior of this species or on its brain morphology. Considering the lack of information in the literature about the brain and internal structures of Galea spixii, this study aimed to stereologic evaluate the brain as well as the volumetric proportions of the hippocampus and corpus callosum. Therefore, ten healthy animals were used from the Wild Animal Multiplication Center of the Universidade Federal Rural do Semiárido. The brains were measured in terms of external length, height and width, followed by fixation in paraformaldehyde solution 4% and coronary cuts with a thickness of 4mm and the rostral face of each cut was photographed, with the images being analyzed to determine the volumetric proportions of the required areas. There was no statistically significant difference between the means of volume, length, width and height when the right and left hemispheres were compared, and there was also no statistically significant difference between the volume of the corpus callosum and hippocampus in both hemispheres. The brain of Galea spixii is larger when compared to the rodent Rattus norvegicus. Volumetric differences may be responsible for distinct behavioral aspects between these species.

Adipocytokines are substances produced by adipocytes responsible for the regulation of several physiological processes. Among those substances, leptin and adiponectin have been intensively investigated because of their possible effects on metabolism, reproduction, hematopoiesis and cardiovascular system. The current study aimed to assess the effects of adipocytokines, leptin and adiponectin on cardiac and respiratory functions, as well as on the hematological parameters of healthy female dogs of different breeds. Parameters of rectal temperature, diastolic blood pressure, systolic blood pressure, mean arterial pressure, pulse, heart rate and respiratory rate were evaluated in fifty two healthy female dogs. Blood samples were collected for complete blood count and plasma leptin and adiponectin measurement via ELISA technique. There was no difference in circulating levels of adipocytokines among the different breeds (p ≤ 0,05). Negative correlation between leptin and mean corpuscular hemoglobin concentration was found, while it was positive regarding systolic blood pressure, heart rate and breathing. Adiponectin was positively correlated with red blood cells and platelets and negatively with heart rate, respiratory rate, diastolic blood pressure and pulse. Adipocytokines, leptin and adiponectin, exert regulatory effects on cardiorespiratory function and hematopoiesis in healthy female dogs.(AU)

Background: Due to the numerous complications that enteropexy may cause in domestic animals and humans, this study aimed at investigating the microscopic level, the damage generated by this technique in mice, in order to investigate the morphometric changes caused by enteropexy technique in rats. Materials, Methods & Results: Eighteen Wistar rats were submitted to surgical technique of enteropexy. To evaluate intestinal disorders they were euthanized at 30 (Group I), 60 (group II) and 90 (group III) days after the procedure. The animals were perfused with 2.5% glutaraldehyde and 4% paraformaldehyde for the removal of intestinal fragments for analysis in conventional microscopy and scanning electron microscopy. In classical histopathology, group I presented mild lesions with necrosis of the epithelium and infiltration of mononuclear cells. After 60 days, extensive ischemic necrosis area was observed, characterized by the denudation of epithelium cells and cellular debris in the lumen surface and loss of intestinal crypts. After 90 days (group III) lesions were evident and were characterized by strong coagulative necrosis of epithelial cells and intestinal crypts. Under electron microscopy, group I showed early fusion of the adjacent intestinal walls. After 60 days there was adherence of luminal stenosis and intestinal walls. In group III loss of epithelium and substitution [...](AU)

O adenocarcinoma secretório cutâneo corresponde a um tumor maligno oriundo da glândula sudorípara apócrina, sendo incomum em caninos. Objetivou-se descrever tal neoplasia nessa espécie. Uma cadela, nove anos, raça Labrador Retriever, possuía lesão na pata dianteira direita, com três meses de evolução. A paciente foi submetida ao exame físico. Optou-se por realizar biopsia incisional e o material obtido foi enviado para a histopatologia. Havia um tumor dermossubcutâneo, com oito cm de diâmetro, envolvendo o terceiro dígito do membro torácico direito. Não ocorriam proliferações em outras regiões anatômicas. O padrão lesional histológico foi compatível com adenocarcinoma apócrino secretório tegumentar. Deve-se incluir o mesmo na diferenciação das demais neoformações tegumentares crônicas caninas.

A micobacteriose cutânea atípica é uma enfermidade incomum em gatos domésticos, principalmente dos oriundosdo Nordeste brasileiro. Objetivou-se relatar tal dermatopatia em felino autóctone da cidade de Mossoró, RioGrande do Norte, Brasil. Uma gata, dez anos, sem raça definida, possuía lesão tegumentar no abdômen. A pacientefoi submetida ao exame físico. Optou-se por realizar biopsia excisional e o material obtido foi enviado paraa histopatologia, com uso de coloração especial para micobactérias. Havia uma placa dermossubcutânea, envolvendoa região das glândulas mamárias abdominais caudais. A análise clínica-histopatológica definiu um quadrode micobacteriose cutânea atípica. Deve-se considerar tal dermatopatia em gatos da região Nordeste do Brasil.
