ABSTRACT

Arrabidaea chica (Humb. & Bompl.) Verl. is an herb popularly used in the treatment of anemia in the Brazilian Amazon region, and little is known about its mineral content. Therefore, the elemental contents of Cu, Fe, Mn, and Zn were determined in the dried leaves and tea obtained by decoction and infusion of the three varieties of the medicinal plant using flame atomic absorption spectrometry after acid wet digestion of the samples. In general, the levels of the minerals are in good agreement with other studies involving medicinal plants, and the variety AC2 had the highest concentrations of all elements both in dried leaves and tea. Iron was found to be the most abundant in dried leaves (38.4-115.5 µg g(-1)), whereas manganese had the highest extraction efficiencies both in decoction (56.1-62.7%) and infusion (45.6-63.6%). Additionally, the decoction was more efficient in the extraction of almost all elements. The consumption of the decoction of variety AC2 may contribute to a small proportion to the daily requirements of Mn.

ABSTRACT

Atualmente, as hiperlipidemias säo um dos principais fatores de risco para o infarto no miocárdio. Um dos objetivos básicos da pesquisa mundial sobre riscos cardiovasculares tem sido definiras médias de níveis lipídicos séricos e a prevalência de todos os tipos de hiperlipidemias na sociedade. O presente estudo, näo é um estudo randomizado. Tem por finalidade mostrar o comportamento dos triglicérides em 4359 pacientes examinados de janeiro a outubro de 1999. Os resultados indicam que o sexo feminino apresenta padräo de anormalidade a partir da faixa etáriaaa de 25 a 29 anos e no sexo masculino, a partir da de 20 a 24 anos de idade, o que vem sugerir, a necessidade de um controle mais efetivo, até que se determine o motivo desta alterabilidade. Os dados foram colhidos diretamente dos livros de registro de resultados do Laboratório de Bioquímica Clínica do Laboratório Central do Estado do Amazonas

ABSTRACT

Emulsoes de composicao semelhante a das lipoproteinas plasmaticas de baixa densidade (LDL), sem apolipoproteinas, preparadas por sonicacao dos constituintes lipidicos, com adicao de (1-14C)-oleato de colesterol e purificadas por ultracentrifugacao, foram injetados em dez pacientes com hipercolesterolemia, quatro com hipertrigliceridemia e dez individuos normolipidemicos
