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.

RESUMO Em seres humanos, a adiponectinemia está associada à obesidade e ao risco aumentado a uma ampla variedade de cânceres. Embora o papel dessa adipocina esteja bem documentado na patogênese do câncer em humanos, tal associação permanece a ser determinada em cães. Nesses animais, a relação da adiponectina com a carcinogênese parece ser ainda meramente especulativa. Nesse contexto, buscou-se nesta investigação comparar os níveis séricos de adiponectina em fêmeas hígidas e em portadoras de carcinomas mamários com diagnóstico histopatológico de carcinoma mamário tubular simples estágio 4, com comprometimento de linfonodos, porém sem metástases a distância detectadas. Foi observado que as cadelas diagnosticadas com carcinoma mamário tiveram níveis séricos... |

The Cl- secretion via Ca2+-activated Cl- channel (CaCC) is critical for fluid secretion in exocrine glands like the salivary gland. Also in the mammary gland, it has been hypothesized that CaCC plays an important role in the secretion of Cl- and aqueous phase of milk. However, there has been no evidence for the functional expression of CaCC in native mammary secretory (MS) cells of lactating animals. We therefore assessed membrane current in MS cells that were freshly isolated from lactating mice using whole cell patch-clamp techniques. In MS cells, we detected CaCC current that exhibited the following characteristics: 1) Ca2+-dependent activation at the concentrations of sub-micromolar range; 2) voltage-dependent activation; 3) slow kinetics for... |

ABSTRACT The aim of this report is to describe the first histopathological, immunohistochemical, and clinical characteristics of a feline glycogen-rich clear cell carcinoma (GRCCC). A Persian queen was admitted with mammary gland tumors and underwent radical unilateral mastectomy. Overall survival was considered 33 days and death was due to clinical evolution of the disease. Microscopic evaluation demonstrated epithelial cells arranged in a predominantly solid pattern, tumor cells presented an ample, granular, and foamy clear cytoplasm, and moderate cellular pleomorfism. The presence of cytoplasmatic glycogen was confirmed through diastase digestion followed by PAS staining. Histopathological and histochemical findings lead to the diagnosis of GRCCC with... |

RESUMO O estresse oxidativo causa peroxidação lipídica e formação de substâncias reativas ao ácido tiobarbitúrico (TBARS), processo que está comprovadamente associado à progressão de neoplasias malignas em seres humanos. Por sua vez, espécies reativas de oxigênio (EROs) são produzidas no processo carcinogênico, de forma que a geração de EROs parece ser, ao mesmo tempo, causa e consequência dele. Em cães, a associação da peroxidação lipídica com a carcinogênese permanece ainda obscura, com estudos escassos, de resultados conflitantes, que, muitas vezes, incluem, dentro de um mesmo grupo amostral, animais portadores de tumores heterogêneos dos pontos de vista morfológico e comportamental, além de estes se apresentarem em estágios bastante distintos. Nesse... |

ABSTRACT Mammary disorders in mares are rare and usually only one animal per paddock is affected. In this report, two mares with 7 and 9 years old, were concomitantly diagnosis of chronic pyogranulomatous mastitis, associated with the Splendore-Hoeppli reaction, indicative of botryomycosis a rare, chronic suppurative disease with microabscess formation, characterized by in vivo formation of eosinophilic materials around microorganisms or biologically inert material. Various bacteria can cause botryomycosis in horses, and the most frequently isolated one is Staphylococcus sp., particularly S. aureus. This report confirms the role of Staphylococcus sp.; however, specifically S. hyicus and S. cohnii that prior to the current report, had not been associated... |

The correlation between microvessel density and mast cells density in canine mammary tumors was studied. Sixty-five samples of canine mammary tumors, being 24 benign and 41 malignant, were analyzed. The routine Toluidine Blue staining method was used to assess the mast cells. To evaluate angiogenesis, the immunohistochemical expression of CD31 was assessed. There was no significant difference in either mast cells (P=0.44) or microvessel density (P=0.77) between malignant and benign tumors. A positive correlation was observed between microvessel density and mast cells (r=0.39; P=0.011) in malignant tumors. These results suggest that mast cells may play a role in canine mammary malignant tumors development, promoting angiogenesis, similar to some tumors... |

The aim of this work was to evaluate the association between milk flow, teat morphological measurements and subclinical mastitis prevalence in Gir cows. Eighty cows in the 2nd and 3rd lactations, with 90 to 200 days of lactation, were divided according to milk flow during milking into fast or slow groups. Teat morphometry was assessed by ultrasound scanning of the right anterior teat and external measurements. Milk samples were collected for somatic cells count (SCC) and microbiological culture. The effect of milk flow during milking was evaluated by analysis of variance of milk yield, SCC, morphometry and external measurements. The association of morphometry and external measurements of the teats with the SCC and microorganisms found in milk were... |

Increased levels of androgens in postmenopausal women are considered to be a risk factor for breast cancer. Testosterone, alone or in combination with estrogen, induces epithelial dysplasia and mammary tumors in Noble rats. Since this model of hormone-induced neoplasia has not been reported in other rat strains, we studied the effect of testosterone on the mammary gland morphology of female Wistar rats. Sixty adult, non-castrated, female Wistar rats were implanted in the dorsum midline with a silicone tube containing 50 mg testosterone (testosterone propionate in 30 animals and non-esterified testosterone in the remaining 30 animals) and 20 additional animals were implanted with empty tubes and used as control. Five animals per group were killed 30, 60,... |

No Brasil, a homeopatia é a principal forma de controle da mastite em rebanhos orgânicos. Entretanto, desconhece-se a capacidade desse tipo de tratamento de controlar bactérias patogênicas relevantes à saúde animal e humana, como aquelas do gênero Staphylococcus. Esses micro-organismos apresentam fatores de patogenicidade, como a produção de biofilmes e questiona-se a possibilidade de essas bactérias permanecerem na glândula mamária de vacas tratadas com homeopatia, mesmo após o uso destas terapias alternativas. Assim, buscou-se investigar Staphylococcus spp. em leite de vacas com tratamento homeopático contra a mastite e a formação in vitro de biofilmes por esses patógenos. As vacas lactantes foram divididas em dois grupos antes do início do experimento,... |
