| ABSTRACT Gene expression of CDKN1A, CDKN1B, and TP53, and immunostaining of p21, p27 and p53 were evaluated to verify the role of these cell cycle inhibitors in canine prostates with proliferative inflammatory atrophy-PIA and prostatic carcinoma-PC. Seventy samples, 15 normal, 30PIA and 25PC. Regarding number of p27 and p53 labeled cells, difference between normal and PIA and PC was observed, as well as between PIA and PC for p53. Immunostaining intensities of p21, p27 and p53 were different when comparing normal tissues to PIA and PC. Sixteen cDNA of canine prostatic FFPE tissue were subjected to RT-PCR and RT-qPCR, four normal, three PIA, and nine PC. CDKN1A mRNA was detected in four PC by RT-PCR, and it was overexpressed when compared to normal by... |

| Avaliou-se a viabilidade do emprego da cartilagem auricular bovina conservada em glutaraldeído a 4% na hernioplastia experimental, empregando-se seis coelhos adultos, machos, da raça Nova Zelândia. Para obtenção da hérnia incisional, removeu-se um segmento elíptico de 3cm de comprimento por 1cm de largura, no ponto central à primeira incisão, envolvendo fáscia e tecido muscular, na região da cicatriz umbilical. Dois animais de cada vez foram sacrificados aos 15, 30 e 45 dias após a cirurgia. Nos sacrificados aos 15 dias, observaram-se áreas focais de inflamação, caracterizadas por abscesso e fístula. À microscopia, observou-se área de inflamação e necrose próxima à periferia do implante. Nas amostras colhidas dos animais sacrificados aos 30 dias, não foram... |

| ABSTRACT The canine transmissible venereal tumor (TVT) affects the external genitalia of dogs by the natural transplant of viable tumor cells. Thus, this research aimed to diagnose and characterize TVT morphological patterns, identify the insertion of the LINE-1 element in C-MYC gene, by means of the polymerase chain reaction (PCR), and evaluate the immunohistochemical expression of C-MYC, p53, p21 and p27 proteins. The relationship between C-MYC and p53 proteins and their interference on the expression of p21 and p27 were also studied. For that, 20 samples of naturally occurring TVT were used, subjected to cytopathological, histopathological and immunohistochemical analysis, and to molecular diagnosis of neoplasia. The increased tissue expression and the... |

| Confeccionou-se um microarranjo de tecido (TMA) com 146 amostras de lesões prostáticas caninas. Este continha 17,2% de hiperplasia prostática benigna (HPB), 32,4% de atrofia inflamatória proliferativa (PIA), 2,6% de prostatite, 8,6% de focos de neoplasia intraepitelial prostática (PIN), 29,1% de carcinomas e 9,3% de próstatas normais. Cortes histológicos sequenciais foram feitos e utilizados para reação de imunoistoquímica com os anticorpos primários anti-p-53, anti-NOS-2 e anti-GSTP. Avaliou-se de cada core o escore de células marcadas para cada anticorpo utilizado. Os resultados foram tabulados por grupo diagnóstico e submetidos ao teste Tuckey. Os carcinomas prostáticos do cão e a PIA apresentaram maior número de amostras (41) com mais de 75% das... |

| ABSTRACT A 9-year-old Girolando dairy cow, weighing 400kg, with a history of increased volume in the right parotid region, which extended to the submandibular region, was assisted. Fine needle aspiration cytology was performed, and the cytological findings were consistent with malignant neoplasm of epithelial origin (carcinoma). Because of the unfavorable prognosis, the animal was euthanized and submitted to an anatomopathological examination. Samples of the increased parotid and affected lymph nodes were collected for histopathological evaluation. The microscopic changes were accentuated features of anaplasia, moderate cell proliferation, atypical mitotic figures, and necrosis. Stroma ranged from delicate to scirrhous, and the tumor boundaries were not... |
