| A- and B-modes ultrasonographic changes in the thickness of various structures of the eyeball in male and female English Cocker Spaniel dogs with and without nondiabetic cataracts were evaluated. Sixteen dogs with cataracts (32 eyes) and seven normal dogs (14 eyes) older than eight years were selected. A- and B-modes ultrasonography was performed with a 10MHz transducer. Data was statistically evaluated by one way ANOVA. Mean and standard deviations of various ocular structures for dogs with and without cataracts were, respectively, anterior chamber: 3.041±0.828mm, 3.373±1.040mm; lens: 6.817±1.117mm, 7.062±0.477mm; vitreous: 10.056±0.754mm, 9.523±0.705mm; and axial length: 19.909±1.103mm, 19.958±1.050mm. Ocular measurements between right and left eyes,... |

| The atypical cutaneous tumor of a 9-year-old mixed breed female dog was examined. The tumor was well-demarcated and histologically composed of a trichoblastic area, tricholemmal area and apocrine glandular area. Neoplastic cells in trichoblastic area and tricholemmal area had PAS-positive granules in the cytoplasm and were positive for pan-cytokeratin, cytokeratin 5/6, 14 and 19 and p63. Neoplastic cells in trichoblastic area were also positive for cytokeratin 15 and CD34. Neoplastic cells in apocrine glandular area were positive for pan-cytokeratin and cytokeratin 7,18 and 19. Myoepithelial cell proliferation with osteocartilaginous metaplasia was observed in this area. Since neoplastic cells showed multiphenotypic differentiation for hair follicles and... |

| The authors describe their experience with an automated immunohistochemical system applied to canine tissue samples. Twenty human cellular markers specific monoclonal and polyclonal antibodies and two different antigen retrieval methods were used in normal and neoplastic breast tissue, as well as skin samples obtained from female dogs of pure and mixed breeds. The antibodies tested were the most frequently used in human and veterinary medicine studies, employed with diagnostic purposes in breast pathology, as well as in cancer research. Most of them may be used to study other normal and abnormal tissues and included cytokeratins, progesterone receptor, c-erbB2, p53, MIB-1, PCNA, EMA, vimentin, desmin, alpha-actin, S-100, pan-cadherin, and E-cadherin. The... |

| The dimorphic fungus Paracoccidioides brasiliensis is the etiological agent of paracoccidioidomycosis, a human granulomatous disease. Recently the first case of natural disease in dogs was reported. The complement system is an important effector component of humoral immunity against infectious agents. Therefore, the aim of this study was to evaluate the activation of the dog alternative complement pathway by P. brasiliensis. Initially, the ability of erythrocytes of guinea pig, rabbit, sheep, chicken and swine to activate the dog alternative pathway was evaluated. The guinea pig erythrocytes showed the greatest capacity to activate dog alternative pathway. The alternative (AH50) hemolytic activity was evaluated in 27 serum samples from healthy dogs and the... |

| Visceral leishmaniasis is a zoonotic disease caused by parasites of the Leishmania genus. Dog is the major source of infection to man, especially in urban areas. The authors report a case of visceral leishmaniasis in a pit bull female dog from Bocaina, São Paulo, Brazil. The animal presented clinical signs compatible with leishmaniasis, including skin lesions in the body and partial damage of the external ears. The indirect fluorescent antibody test (IFAT) demonstrated a titer of 1280, and promastigote forms of Leishmania sp were isolated by the culture of bone marrow puncture. Cytological analysis of the lymph node and smear of the bone marrow puncture revealed macrophages containing amastigote forms of Leishmania sp in their inner region. The test of... |

| Biomolecular evidence has shown that ductal carcinoma in situ(DCIS) may develop into invasive carcinoma of the canine mammary gland, and mutations in proto-oncogenes HER2 and EGFR; two members of the family of epidermal growth factor receptors, may be involved in this process. The purpose of this study was the characterization of the immunohistochemical expression of the EGFR and HER2 proteins in the process of neoplastic transformation, supposedly present in ductal carcinomas in situin canine mammary glands. Fifteen cases of DCIS were evaluated, with a higher expression of HER2 and EGFR being observed in low-grade carcinomas when compared with high-grade neoplasms, and with a high positive statistical correlation in the latter. Results suggest that... |

| This article describes the occurrence of aortic body tumors in four dogs from Southern Brazil. All dogs were males, more than 9 year of age; most of these were from the Boxer breed of dogs. The animals had large neoplastic growths at the base of the heart, which demonstrated histologic characteristics consistent with that of aortic body tumor. By immunohistochemistry, tissue sections from all dogs reacted positively to neuron specific enolase. These cases might represent the first description of this tumor in dogs from Brazil, as confirmed by immunohistochemistry. |

| Twelve male, mongrel, adult dogs were subcutaneously transplanted with cells originated from two canine transmissible venereal tumors (TVT). The aim was to demonstrate and to quantify the occurrence of apoptosis in the TVT regression. After six months of transplantation, a tumor sample was obtained from each dog, being six dogs with TVT in the growing phase and six in the regression phase as verified by daily measurements. Samples were processed for histological and ultrastructural purposes as well as for DNA extraction. Sections of 4µm were stained by HE, Shorr, methyl green pyronine, Van Gieson, TUNEL reaction and immunostained for P53. The Shorr stained sections went through morphometry that demonstrated an increase of the apoptotic cells per field in... |

| Gastropexy techniques are performed aiming to adhere permanently the stomach to the abdomen, being this one of the most common indications for prevention and treatment of gastric dilatation-volvulus (GDV). The only accepted method for the prevention of GDV is the prophylactic gastropexy, and the laparoscopic-assisted procedure is quick and easy to perform. It is aimed to report the association of laparoscopic-assisted prophylactic gastropexyand elective ovariohysterectomy (OVH) in a two years old Great dane bitch using the two-portals access, when it was observed rapid and complete recovery. It is concluded that the two portals laparoscopic-assisted prophylactic gastropexy is feasible and safe in dogs, when combined with elective OVH. It makes the... |

| Mitotic index, nuclear diameter, number of nucleolar organizing regions, and Ki-67 expression, in hair follicle tumors of 82 dogs were evaluated. Tissue specimens were used to prepare sections for histological staining for number of nucleolar organizing region and immunohistochemical staining for Ki-67. Tumors were classified as trichoblastoma (n=32), benign trichoepithelioma (n=30), pilomatricoma (n=7), malignant trichoepithelioma (n=6), infundibular keratinizing acanthoma (n=5), and tricholemmoma (n=2). Head, dorsum, and limbs were the most affected sites. Malignant trichoepithelioma presented significantly higher mitotic index, number of nucleolar organizing regions and Ki-67 expression. Regarding benign neoplasms, trichoblastoma presented significantly... |

| A meningoencefalomielite granulomatosa (MEG) ocorre em cães de todas as raças, em qualquer idade e já foi descrita em vários países. Sua etiologia não é definida, mas sugere-se que uma reação de hipersensibilidade retardada esteja envolvida. Nas lesões há ocorrência de profuso infiltrado de células B e T, além de macrófagos. No presente estudo verificou-se, com técnicas de imunoistoquímica, a distribuição e a morfologia de astrócitos imunorreativos à proteína glial fibrilar ácida no encéfalo de cães acometidos por MEG e também as proporções de células imunorreativas a IgG, IgM e CD3. Foram utilizados seis cães, três machos e três fêmeas, com idade entre dois e seis anos. Observou-se acentuada astrocitose principalmente ao redor das lesões, com aumento da... |

| The effects of inspired oxygen fractions (FiO2) of 1 and 0.6 on bispectral index (BIS) in dogs with high intracranial pressure, submitted to a continuous rate infusion of propofol were evaluated. Eight dogs were anesthetized on two occasions, receiving, during controlled ventilation, an FiO2 = 1 (G100) or an FiO2 = 0.6 (G60). Propofol was used for induction (10mg.kg-1, IV), followed by a continuous rate infusion (0.6mg.kg-1.minute-1). After 20 minutes, a fiber-optic catheter was implanted on the surface of the right cerebral cortex to monitor the intracranial pressure, the baseline measurements of BIS values, signal quality index, suppression ratio number, electromyogram indicator, end-tidal carbon dioxide partial pressure, mean arterial pressure,... |
