RESUMO
Byrsonima sericea is a species native to Brazil that is widely used in traditional medicine. The seed ethanol extract (SEE) had the highest content of total phenols (179.35â mg GAE g-1 extract) and flavonoids (10.42â mg QE g-1 extract) and was the most active in relation to antioxidant activity (DPPH: IC50 =4.25â µg mL-1 and ABTS: IC50 =4.82â µg mL-1 ). The peel/pulp ethanol extract (PEE) had the best anticholinesterase activity (IC50 =6.02â µg mL-1 ). Chromatographic investigation identified gallic acid, isoquercitrin, quercetin and amentoflavone in SEE, and gallic acid, isoquercitrin, quercetin and rutin in PEE. Six fatty acid methyl esters and seven triterpenes were identified, highlighting oleic acid in the seed hexane extract (61.85 %) and in the peel/pulp hexane extract (52.61 %), and betulin in the peel/pulp hexane extract (5.25 %). The substances and biological activities identified in B.â sericea characterize this fruit as a functional food for future studies.

Less than 10% of children under 2 years old with end-stage renal failure in Europe and in the United States of America are treated with haemodialysis. For small children, peritoneal dialysis is often the preferred treatment. Haemodialysis is chosen for a very small number of children, and is only used in some selected centres because of its highly complex technique, the difficulties related to vascular access, and the need to have a skilled and experienced nursing and medical team. With the technological development of recent years, the quality of dialysis treatment offered to paediatric patients has improved considerably and haemodialysis is presently considered to be a safe and efficient treatment for acute or chronic paediatric renal impairment. However, because a successful renal transplant continues to be linked to a better quality of life for children with terminal chronic renal impairment, dialysis ought to be regarded as a temporary treatment method, while waiting for a renal transplant.

Os Autores analisaram soros de 47 Cannis familiaris, de 9 Felis cattus, de 64 Didelphis marsupialis aurita, de 9 dasypus novemcintus, de 4 Cabassous tatouay e de 29 Rattus rattus, através da reaçäo de imunofluorescência indireta, para pesquisar a presença de anticorpos anti Toxoplasma gondii. Estes foram encontrados apenas em C. familiaris (63,8%) e em D. m. aurita (4,7%). Frente aos resultados obtidos, os Autores sugerem que novas pesquisas nesta área sejam realizadas, para que se conheça melhor a importância epidemiológica de várias espécies animais na disseminaçäo da toxoplasmose
