| Avaliaram-se as alterações histológicas do tecido laminar, obtido por biopsia, em 20 equinos portadores de laminite induzida por sobrecarga de carboidratos e tratados com ketoprofeno, fenilbutazona ou flunixin meglumine. A biopsia foi colhida dos dígitos torácicos 72 horas após a indução. Os achados histológicos foram comparados com os achados de amostras de equinos isentos de laminite. Infiltrado inflamatório neutrofílico foi observado em 80%, congestão em 50%, hemorragia em 35% e hiperplasia na túnica íntima das arteríolas das lâminas dérmicas primárias em 15% das amostras. As taxas de microtrombos e coágulos foram 15% e 20%, respectivamente. Estes achados parecem decorrer dos distúrbios circulatórios que ocasionaram edema, congestão e hiperemia,... |

| Drospirenone (DRSP) is a progestin with anti-aldosterone properties and it reduces blood pressure in hypertensive women. However, the effects of DRSP on endothelium-dependent coronary vasodilation have not been evaluated. This study investigated the effects of combined therapy with estrogen (E2) and DRSP on endothelium-dependent vasodilation of the coronary bed of ovariectomized (OVX) spontaneously hypertensive rats. Female spontaneously hypertensive rats (n=87) at 12 weeks of age were randomly divided into sham operated (Sham), OVX, OVX treated with E2 (E2), and OVX treated with E2 and DRSP (E2+DRSP) groups. Hemodynamic parameters were directly evaluated by catheter insertion into the femoral artery. Endothelium-dependent vasodilation in response to... |

| Brucella ovis is a major cause of epididymitis in sexually mature rams, resulting in subfertility, infertility, and economic losses for the sheep industry worldwide. The aim of this study was to develop an indirect ELISA (iELISA) using recombinant proteins, namely rBoP59 and rBP26, as antigens for serological diagnosis of B. ovisinfection. The BoP59 and BP26 recombinant proteins were expressed in E. coli and purified by affinity chromatography. Antigenicity was tested by Western blot and iELISA. Standardization of iELISA was performed with 500ng and 1µg BoP59 and rBP26 per well, testing serum from uninfected and experimentally infected rams. rBP26 was effective in distinguishing positive from negative rams. The rBP26 iELISA developed in this study is the... |

| ABSTRACT A captive 12-year-old female maned wolf (Chrysocyon brachyurus), previously diagnosed with visceral leishmaniasis, developed severe myiasis in the right ear, followed by prostration and death. A firm solid nodule, measuring 1 x 3cm, was grossly observed in the pancreas. Histologically, there was neoplastic proliferation in the pancreas and pancreatic lymph node. Neoplastic cells had a neuroendocrine pattern, and were positive for gastrin and pancreatic polypeptide by immunohistochemistry. The wolf had also ulcerative gastritis. To the best of our knowledge is the first reported case gastrinoma in this species. |

| Morphological changes in the placenta at periparturition and the involvement of apoptosis controlling cell populations in the placentome were evaluated in Holstein and Nelore cows. Twenty-two Holstein cows at the end of gestation with normal non-induced parturition (group I) and 10 Holstein cows with induced parturition (group II) were used in this study. In addition, groups III and IV were constituted by 10 Nelore cows at the end of gestation with normal non-induced parturition and 21 Nelore cows with induced parturition, respectivelly. Binucleate trophoblastic cells, epithelial caruncular cells and apoptotic bodies were quantified by light microscopy. Apoptosis was further evaluated by transmission electron microscopy, ELISA and DNA electrophoresis in... |

| Brucelose bovina causada por Brucella abortus é uma importante doença zoonótica, caracterizada pela ocorrência de aborto durante o último trimestre da gestação, o que resulta em diminuição da fertilidade da produção de leite em vacas. A identificação de genes associados à resistência natural contra brucelose tem sido investigada com o objetivo de selecionar animais resistentes à doença. Em bovinos, é controversa a resistência natural contra B. abortus associada ao polimorfismo da região 3' UTR do gene Slc11A1 (Nramp1). Polimorfismos localizados na sequência codificadora de Slc11A1 têm sido identificados em bovinos, contudo a influência sobre a resistência natural contra brucelose não é conhecida. No presente estudo, três novos polimorfismos do gene Slc11A1... |

| The objective of this report was to describe the pathological changes in the urinary bladder of female rats naturally infected with Trichosomoides crassicauda. Forty eight 5 to 8 months of age female Wistar rats were studied. At necropsy uroliths were detected in seven animals (14.6%). Among the bladders that contained the parasite only three (6.3%) did not show any significant histological change and were considered normal, but on the contrary, three (6.3%) did contain papillomas and uroliths, four (8.3%) had uroliths associated with epithelial hyperplasia ranging from moderate to severe, and the remaining (79.2%) showed variable degrees of epithelial hyperplasia and inflammation without urolithiasis. It cannot be concluded whether irritation of the... |

| The aim of the present study was to evaluate a species-specific nested PCR based on a previously described species-specific PCR for detection of B. ovis in semen and urine samples of experimentally infected rams. The performance of the species-specific nested PCR was compared with the results of a genus-specific PCR. Fourteen rams were experimentally infected with the Brucella ovis REO 198 strain and samples of semen and urine were collected every week up to 180 days post infection. Out of 83 semen samples collected, 42 (50.6%) were positive for the species-specific nested PCR, and 23 (27.7%) were positive for the genus-specific PCR. Out of 75 urine samples, 49 (65.3%) were positive for the species-specific nested PCR, whereas 11 (14.6%) were... |

| Estrogen deficiency and hypertension are considered major risk factors for the development of coronary heart disease. On the other hand, exercise training is considered an effective form to prevent and treat cardiovascular diseases. However, the effects of swimming training (SW) on coronary vascular reactivity in female ovariectomized hypertensive rats are not known. We aimed to evaluate the effects of SW on endothelium-dependent coronary vasodilation in ovariectomized hypertensive rats. Three-month old spontaneously hypertensive rats (SHR, n=50) were divided into four groups: sham (SH), sham plus swimming training (SSW), ovariectomized (OVX), and ovariectomized plus swimming training (OSW). The SW protocol (5 times/week, 60 min/day) was conducted for 8... |

| Estudou-se o efeito da administração de succinato sódico de hidrocortisona (SSH) no desenvolvimento de lesões no cório laminar de eqüinos. Doze animais foram submetidos à laparotomia sob anestesia geral e à isquemia total em dois segmentos do jejuno, enquanto três foram usados como controle. Após uma hora de isquemia, seis animais receberam 4,0mg/kg de SSH por via intravenosa (grupo T) e seis receberam placebo (grupo NT). Após duas horas de isquemia foi restabelecido o fluxo de sangue local e, decorridas duas horas de reperfusão, foi realizada a laparorrafia e permitiu-se a recuperação anestésica. Após 12 horas do início da reperfusão, os animais foram sacrificados e deles colhidas amostras de tecido laminar para avaliação histomorfológica. As alterações... |
