Objetivo: O presente trabalho, dividido em três estudos, teve como objetivo geral identificar e quantificar a liberação de componentes e avaliar a citotoxicidade e a biocompatibilidade de cimentos de ionômero de vidro (CIVs). Método: Para o estudo 1, extratos dos CIVs Vitrebond (VB), Fuji Lining LC (FL), Vitremer (VM), Fuji II LC (FII), Ketac Fil Plus (KF) e Ketac Molar Easymix (KM) foram obtidos pela imersão de corpos-de-prova em meio de cultura celular (DMEM). Esses extratos (n=9 por grupo) foram analisados por eletrodo específico quanto à presença de flúor e por espectrometria de absorção atômica quanto à presença de alumínio e zinco. HEMA e iodobenzeno foram identificados por CG/EM (n=6). Para o estudo 2, células MDPC-23 foram colocadas em contato com os extratos dos CIVs por 24 horas. Em seguida, foram avaliadas a atividade da desidrogenase succínica (SDH) (n=8), a produção de proteína total (PT) (n=8), a atividade da fosfatase alcalina (FAL) (n=8) e a morfologia celular (n=2). Para o estudo 3, tubos de polietileno (n=24 por grupo) foram preenchidos com os CIVs e implantados no tecido subcutâneo de 42 ratos. Como grupo controle foi utilizada a guta-percha. Após 7 ou 15 dias de pós-operatório, metade dos espécimes de cada grupo e período (n=6) foi preparada para análise histológica, e os demais (n=6) para análise da expressão de genes que codificam para IL-1? e TNF-?. Resultados: Os extratos de todos os CIVs apresentaram uma concentração de flúor significativamente maior do que o meio de cultura DMEM (controle), tendo o VB liberado maior quantidade, estatisticamente significante, do que os demais CIVs. O VB foi, também, o único material que liberou quantidades relativamente altas de alumínio e de zinco. O HEMA foi identificado nos extratos de todos os CIVs modificados por resina (VB, FL, VM e FII), e o iodobenzeno... (Resumo completo, clicar acesso eletrônico abaixo)

Canine Pyometra is a uterine disease that occurs in sexually mature bitches, with higher incidence in nulliparous and animals over 4 years and is characterized by presenting an accumulation of pus in the uterine lumen, usually occurring in diestrus. Laboratory tests are important tools for the detection of metabolic abnormalities associated with sepsis and renal function, which are serious consequences of pyometra. In blood the main findings are normochromic non-regenerative anemia, presence of dehydration, and sometimes thrombocytopenia. The WBC count may be normal but most often occurs a neutrophilic leukocytosis with a left shift, monocytosis and the presence of toxic neutrophils. In less than 1 / 3 of the animals the presence of azotemia is present and a density lower than 1035 is detected in the urine of almost 90% of bitches which may be in normal range at the onset of the desease. Urinary protein loss is rare but the protein may be elevated in the reagent strip due to urinary contamination by uterine secretion. The increase of gamma-glutamyltransferase (GGT), alkaline phosphatase (ALP), aspartate aminotransferase (AST) and creatine kinase (CK) may be present, indicating disorders in the liver. Currently, additional laboratory tests are being studied for the diagnosis of pyometra and its prognosis, such as the measurement of C-reactive protein and fibrinogen for monitoring the recovery of the inflammatory process and the urine electrophoresis to characterize the origin of proteinuria in these animals . The aim of this work is to review the literature on the main laboratory tests that aid the diagnosis of Pyometra

Feline hepatic lipidosis or fatty liver disease is a cholestatic syndrome that affects domestic cats and is characterized by excess fat accumulation in the liver of cats. Symptoms commonly seen with this syndrome are anorexia, weight loss, lethargy, vomiting, jaundice, and occasionally behavioral or neurologic signs such as excessive drooling, blindness, coma, and seizures. The diagnosis is based on the patient history, clinical examination, complementary examination, and the definitive diagnosis is obtained by cytology and/or histopathology of hepatic tissue. In serum biochemistry, the main findings include increased serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate amino transferase (AST) and bilirubin. The gamma glutamyl transferase (GGT) is normal or slightly increased. The cornerstone of therapy is aggressive feeding to supply the cat full caloric requirements. Without aggressive nutritional support and intensive monitoring the fatty liver disease can be fatal

Osteosarcoma is the primary osseous neoplasia frequently diagnosed in dogs and it’s the main answerable for more than 85% of the neoplasias origened from the skeleton. The average age of onset of the lesion is 7 years, especially in large breeds and giant, with males being more affected than females. In general, 75% of osteosarcomas develop in the appendicular skeleton and 25% in the axial. The forelimbs are more affected than the hindlimbs, since support 60% of body weight. The osteosarcoma diagnosis is made by the analys of the animal’s clinic historic, detailed physique exams, blood exams alkaline phosphatase, xray exams, cytology, biopsy. The treatment of choice is the amputation associated to the chemotherapy. However, in some cases the member is preserved by the allograft technic. The chemotherapy associated to the surgery reduces the total load of the tumor, lengthens the interval of the life and improves the quality of pacient’s life. The most used medicines are cisplatin and doxorubicin. They can be used in separated or associated ways. The prognostic of dogs with osteosarcoma is reserved
