RESUMEN
The aim of this study was to investigate the effect of Eugenia uniflora fruit (red type) extract on metabolic status, as well as on neurochemical and behavioral parameters in an animal model of metabolic syndrome induced by a highly palatable diet (HPD). Rats were treated for 150days and divided into 4 experimental groups: standard chow (SC) and water orally, SC and E. uniflora extract (200mg/kg daily, p.o), HPD and water orally, HPD and extract. Our data showed that HPD caused glucose intolerance, increased visceral fat, weight gain, as well as serum glucose, triacylglycerol, total cholesterol and LDL cholesterol; however, E. uniflora prevented these alterations. The extract decreased lipid peroxidation and prevented the reduction of superoxide dismutase and catalase activities in the prefrontal cortex, hippocampus and striatum of animals submitted to HPD. We observed a HPD-induced reduction of thiol content in these cerebral structures. The extract prevented increased acetylcholinesterase activity in the prefrontal cortex caused by HPD and the increase in immobility time observed in the forced swim test. Regarding chemical composition, LC/MS analysis showed the presence of nine anthocyanins as the major compounds. In conclusion, E. uniflora extract showed benefits against metabolic alterations caused by HPD, as well as exhibited antioxidant and antidepressant-like effects.

Abstract Dioctophyme renale is a zoonotic nematode that parasites the kidneys of wild and domestic carnivores, and it has been reported frequently in Brazil. The aim here was to register the number of cases of dogs and cats diagnosed with dioctophymosis by necropsy (1981 to 2014) and ultrasound examination (2010 to 2015) in Pelotas-RS. In this context, a survey was conducted on dioctophymosis cases diagnosed at the Veterinary Pathology Laboratory (LPV) and Veterinary Clinical Hospital (HCV) of the Federal University of Pelotas (UFPel), and at a specialist veterinary imaging diagnostics clinic. In total, 95 cases were registered. The high series of the disease in dogs can be related to the presence of a large number of stray and semi-domestic dogs in the city, and also due to the ingestion of intermediate hosts of D. renale parasitized with the infective larvae. Thus, it can be concluded that Pelotas is a city with favorable conditions for the occurrence of dioctophymosis with high rate of disease in recent years.
Resumo Dioctophyme renale é um nematódeo zoonótico que parasita principalmente o rim de carnívoros silvestres e domésticos, e tem sido relatado com frequência no Brasil. Objetivou-se registrar o número de casos de cães e gatos diagnosticados com dioctofimatose por necropsia (1981 a 2014) e exame ultrassonográfico (2010 a 2015) em Pelotas-RS. Nesse contexto, foi realizado um inquérito de casos de dioctofimatose em animais de companhia no Laboratório de Patologia Veterinária (LPV) e no Hospital de Clínicas Veterinária (HCV) da Universidade Federal de Pelotas (UFPel), e em uma clínica veterinária especializada em diagnóstico por imagem, totalizando 95 casos registrados. A elevada casuística da doença em cães pode estar relacionada à presença de um grande número de cães errantes e semi-domiciliados na cidade, e também devido à ingestão dos hospedeiros intermediários de D. renale parasitados com a larva infectante. Assim, conclui-se que Pelotas é uma cidade propícia para a ocorrência de dioctofimatose, com elevada casuística da doença nos últimos anos.
