RESUMO: Os alimentos funcionais têm sido empregados como adjuvantes no tratamento do câncer de mama. Neste estudo avaliaram-se as respostas hematológicas e bioquímicas clínicas à ação de um alimento funcional administrado a cadelas com diagnóstico de neoplasia mamária maligna. Após a mastectomia, 16 cadelas foram divididas em dois grupos: suplementadas (S) e não suplementadas (NS) com um composto comercial contendo Saccharomyces cerevisiae, mananoligossacarídeos e nutracêuticos. Ambos grupos receberam tratamento quimioterápico com doxorrubicina e carboplatina, alternadamente, em intervalos de 21 dias, por oito sessões, totalizando 168 dias de tratamento. As avaliações clínicas e laboratoriais foram realizadas nos momentos de aplicação do tratamento. Os resultados dos perfis hematológico (hemograma, leucograma e plaquetograma) e bioquímico sérico (ureia, creatinina, albumina, bilirrubina total e direta, alanina aminotransferase, fosfatase alcalina e gama glutamiltransferase - GGT) foram analisados pelo teste de Kruskall Wallis. No grupo S comprovou-se elevação do peso corporal e não foram observados transtornos gastrointestinais ou outros sinais de alteração clínica ao longo do tratamento. Diferentemente no grupo NS, ocorreu perda de peso e alterações clínicas, como diarreia e vômito. No quadro hematológico, constatou-se leucopenia por linfopenia no grupo de cadelas NS e preservação do valores dentro dos parâmetros considerados normais para a espécie no grupo S. Dentre todas as variáveis da bioquímica clínica, constatou-se apenas a elevação da atividade sérica da GGT nos animais do grupo NS, sem alterações no grupo S. Conclui-se que cadelas com neoplasia mamária quando suplementadas com com alimento funcional imunoestimulante apresentam melhor condição clínica, hematológica e dos níveis bioquímicos, particularmente da GGT.
Between October 2016 and October 2017, 63 feline uroliths were analyzed at Universidade Federal de Goiás (UFG) by using both chemical analysis and energy dispersive spectroscopy (EDS). The most frequent mineral type found was struvite (53.9%), followed by urate (39.7%), calcium oxalate (30.1%) and calcium phosphate (25.3%). Calculus containing xanthine, cystine and silica were not observed. Uroliths classified as simple, comprised a total of 34/63. Amongst the 42 animals present in the study, 26 were male and 16 were female. Pure breed animals comprised 14.4% of the total, and the breeds observed within the study were the Persian, Himalayan, Siamese, and Angora. Cats between 25-72 months old were more frequently diagnosed with uroliths. The clinical signs varied between systemic and urinary signs and the most found were anorexia, vomiting, hematuria and dysuria. All patients were either spayed or neutered and 34 patients had no outdoor access. Familial information was unknown in almost 100% of the cases. The results observed in the present study serve as a basis for future comparisons related to the epidemiology of urinary lithiasis in Brazil, especially for the feline species.
To evaluate the use of tenecteplase in transoperative phacoemulsification in healthy rabbits, the study was carried out with fifteen New Zealand rabbits, divided into three groups: control group (CG), untreated group (UG) and treated group (TG). UG and TG were operated by phacoemulsification and TG received 50 µg / 0.3 mL of intracameral tenecteplase. The postoperative evaluations were 24 h, 72 h, 7 days, 15 days and 21 days. In TP21 the animals were submitted to euthanasia and aqueous humor samples were collected. No significant differences were observed in the clinical evaluations between CG and TG in relation to incidence rates of intraocular pressure (IOP), corneal edema, fibrin deposits, hyphema, aqueous flare and synechia. In the physicochemical evaluation of the aqueous humor, there were no significant differences between the three groups in relation to pH values and concentrations of chloride ions. The aqueous humor density values were statistically different between CG and the other groups. In the histological evaluation, there were no significant differences between the groups. The use of tenecteplase in transoperative phacoemulsification in rabbits did not present significant differences in terms of clinical, physicochemical and histological parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
