The hearts of 30 dogs naturally infected with Leishmania infantum chagasi were evaluated histologically and immunohistochemically. Myocardial lesions detected in all dogs, including lymphoplasmacytic myocarditis (27/30), myonecrosis (24/30), increased interstitial collagen (22/30), lepromatous-type granulomatous (7/30), fibrinoid vascular change (3/30), vasculitis (1/30). parasite was the 20 dogs. number parasitized cells correlated intensity inflammation granulomas. results indicate that...

The aim of this study was to evaluate the most frequent lesions in bone marrow dogs naturally infected by Leishmania (Leishmania) chagasi. Thirty-three sacrificed at Zoonosis Control Center Araçatuba, a municipality endemic for visceral leishmaniasis (VL), were used. animals classified as asymptomatic, oligosymptomatic, and symptomatic groups. At necropsy, samples collected from femur, fixed, processed, stained with hematoxylin eosin. lesion intensity mild, moderate, or severe. parasite load...

In canine visceral leishmaniasis (CVL), the abnormalities most commonly observed in clinical examination on animals are lymphadenomegaly and skin lesions. Dogs main domestic reservoir for protozoon Leishmania (L.) chagasi is site of contamination by vector insect. Some protozoa use apoptosis as an immunological escape mechanism. The aim this study was to correlate presence with parasite load inflammatory response lymph nodes dogs naturally infected chagasi. Thirty-three from municipality...

The aim of this study was to evaluate apoptosis and parasite load in the liver spleen dogs with visceral leishmaniosis (VL), using immunohistochemistry. Liver samples from 71 VL were used. showed significant difference between organs infected group (P=0.0219). density (median=2.4) higher than (median=0.8). Immunodetection apoptotic cells predominant lymphocytes differ control (P=0.0307) (P=0.0346). There a correlation (P = 0.0084; r=0.3104) only group, where it observed that, when increasing...

The objective of this study was to analyze morphological changes and parasite loads in the adrenal gland from 45 dogs with visceral leishmaniasis (VL). animals were Zoonosis Control Center Araçatuba, state São Paulo, which is an endemic region for disease. These euthanized due positive diagnoses VL. classified into asymptomatic, oligosymptomatic symptomatic groups. load determined by immunohistochemistry, using VL-positive dog hyperimmune serum. Nine showed inflammatory infiltrate composed,...

The inflammatory response may have pro or anti-neoplastic effects in tumors, depending on the histological type and malignancy level of tumor. This study aimed to evaluate profile predominant cells by immunohistochemistry cutaneus squamous cell carcinoma (SCC) dogs, comparing it with degree differentiation Twenty samples SCC were analyzed. tumors histologically classified into two groups, differentiated (SCCd=12) undifferentiated (SCCu=08). tumor infiltrate was determined...

O estudo anatômico da origem e distribuição do plexo braquial no urubu (Coragyps atratus foetens) foi efetuado em 14 animais, adultos,machos fêmeas oriundos região de Araçatuba (SP). Após a fixação solução aquosa formaldeído 10,00%, realizou-se dissecação bilateral dos plexos braquiais sua distribuição. A análise permitiu verificar, que o urubu, possui quatro troncos, os quais originam-se ramos ventrais nervos espinhais cervicais onze (C11), doze (C12) treze (C13) torácicos um (T1) (T2) 100%...

An anatomic study of the arrangements configured by nerves brachial plexus was carried out in turkeys (Meleagris gallopavo). Thirty adult female were used. Animals obtained from Sadia refrigerator at Chapeco, Santa Catarina State, Brazil. After fixation 10% formaldeyde aqueous solution, bilateral dissection origin out, as well distribution to muscles. The analysis permitted determine that has three stems originate ventral branches cervical 12 (C12) and 13 (C13), thoracic 1 (T1) 2 (T2) 100%...

Introdução: Teoria do Elo, também conhecida como "Link Theory", estabelece uma conexão entre a violência contra animais e interpessoal, especialmente no contexto doméstico. Essa teoria sugere que o abuso de pode ser um indicativo familiar, envolvendo parceiros, crianças outros membros da família. Dessa forma, Elo promove visão integrada mostra proteção dos não deve dissociada humana. Objetivos: Revisar literatura sobre maus-tratos aos humana, além discutir papel médicos veterinários na...

Introdução: A hidronefrose é uma patologia que ocorre pelo acúmulo de urina se inicia na pelve renal, causado por obstrução parcial ou total qualquer parte do trato urinário, desde a renal até uretra. Esse processo acontece devido compressão extrínseca intraluminal, podendo ser unilateral bilateral. Os sinais clínicos são variáveis, como hematúria, retenção urinária e disúria. O diagnóstico feito através dos clínicos, exames imagem citológicos para determinar causa, além complementares...

A ramificação e a distribuição dos nervos frênicos direito esquerdo foram estudadas em 30 músculos diafragmas de gatos domésticos sem raça definida, 7 machos 23 fêmeas, conservados solução formaldeído 10%. Mediante fixação dissecção, observou-se que os se ramificaram para as respectivas partes carnosas do músculo diafragma, pars lumbalis, costalis sternalis, terminaram maior freqüência tronco dorsolateral ramo ventral (63,33%). Notou-se ainda seguintes arranjos: ramos dorsal, lateral...

Abstract The mammary tumor is one of the most common cancer in female dogs and, at present days, there a big focus on study relation between this kind animals and cells that stay around them, like inflammatory cells. objective was to evaluate show where simple carcinomas by immunohistochemistry. Samples (tumor group; n=26) gland samples without (control n=18) were submitted immunohistochemical analysis for detection T lymphocytes, macrophages, plasma MHC-II molecule. mast evaluated...

Abstract Periosteal osteosarcoma is an uncommon primary malignant bone tumor in dogs and humans. This type of one the four variants osteosarcoma. The main feature a superficial lesion without evidence marrow involvement. treatment usually performed limb amputation. There insufficient data on long-term disease-free time, surgical resection or local recurrence dogs. present review aims to gather information periosteal

The ventricular and atrial tributaries of the coronary sinus in ovine represent basic contribution for knowledge cardiac morphology species. In this study, 30 hearts crossbred adult animals, either males or females, bred slaughtered region Aracatuba, Sao Paulo State, Brazil, had been used. After slaughter joint heart lungs were collected brought to laboratory. was isolated, a polyethylene cannula inserted into ostium right atrium, Neoprene-latex 650 blue-tained natural latex diluted water...

Onychogryphosis is one of the main clinical findings in dogs with visceral leishmaniasis (VL); however, research focusing on subungual area infected scarce. This study aims to assess VL that presented or not onychogryphosis by means histopathological analyses and immunohistochemical studies (parasite burden). The third digit thoracic pelvic limbs Leishmania infantum naturally was collected regardless sex, breed age. animals were split into two groups, (G1; n=7) without (G2; n=9). digits...

ABSTRACT: Dendritic cells have attracted great interest from researchers as they may be used targets of tumor immune evasion mechanisms. The main objective this study was to evaluate the relationship between dendritic (DCs) subpopulation in simple type mammary carcinomas female dogs. Two groups samples were used: control group consisted 18 tissue without changes and with 26 carcinomas. In these groups, we evaluated immunodetection immature mature myeloid DCs, plasmacytoid DCs MHC-II. tumor,...
