Amapá amargo (Parahancornia fasciculata (Poir.) Benoist) produz um látex, que se presume ter propriedades medicinais, pois é usado no tratamento da malária, problemas pulmonares, gastrite, e como um agente de cura. Este estudo teve como objetivo analisar estrutural e histoquimicamente os locais de produção e/ou acumúlo de compostos biologicamente ativos, bem como realizar o doseamento de flavonóides presentes no limbo do amapá amargo. Para a análise estrutural e histoquímica foram utilizados protocolos padrão em anatomia vegetal. Considerando que, para o doseamento de flavonóides utilizou-se a espectrometria de absorção na região ultravioleta-visível. O sistema secretor das folhas de amapá amargo é constituído de idioblastos secretores e laticíferos ramificados. Os testes histoquímicos revelaram diferentes tipos de substâncias químicas nos protoplastos celulares de idioblastos e laticíferos. Propriedades farmacológicas do látex de amapa amargo podem ser atribuídas à dois compostos químicos (flavonoides e alcaloides) encontrados neste estudo, ambos estão presentes em idioblastos e laticíferos.

The use of plants to treat diseases or even to cure them is a high diffused popular tradition, and several studies discuss the therapeutic and pharmacological properties of garlic in the reduction of hyperlipidaemias. The objective of the present study was to investigate the influence of the aqueous extract of garlic (Allium sativum) to treat the serum cholesterol of rabbits with experimental hypercholesterolemia. The animals were divided into G1 (control group) and G2 (group treated with garlic). The experiment was developed according to 3 phases: during the 1st phase, all animals were provided with a regular diet to evaluate the basal cholesterol; during the 2nd phase, all animals received a supplemented diet until the end of the experiment, in order to develop hypercholesterolemia and, in the 3rd phase, the animals on G2 received the garlic treatment. The cholesterol registered on the 1st phase was 39.94 ± 9.57 mg dL-1. On the 2nd phase, there was an increase on the serum cholesterol level in both groups - higher than 100 mg dL-1. Concerning the treatment, the garlic did not reduce the serum cholesterol in rabbits.

The jambu belongs to the family Asteraceae, tropical crop, nowadays, this plant has been considered as a promising vegetable crop, because to its pharmacological properties. Despite this novelty, the vegetable remains invisible in the statistics of production and market in the state of Para, Brazil. This research was carried out with the aim of comparing the economic productivity and phenological development by the morpho-physiological growth indexes of two cultivars of jambu organic manure and mineral fertilizers. The experiment was carried out at the Sao Manuel Experimental Farm (Sao Manuel-SP), which belongs to the Faculdade de Ciencias Agronomicas - UNESP, campus Botucatu. The experimental design was a factorial randomized blocks (2 x 2) with two fertilization (organic and mineral) and two cultivars (Jambuarana and Nazareth), with six replications, two fertilization (organic and mineral) and two cultivars (Jambuarana and Nazareth). The following characteristics were evaluated: Plant height (cm), Leaf area (cm(2)), Fresh mass (g), Dry mass (g), Leaf area index (LAI), Leaf area ratio (LAR), Specific leaf Area (SLA), Leaf Weight Ratio (LWR), Amount of water in the plant (QAPA) (g per plant set), Leaf specific weight (LSW) (g cm(-2) per plant set) and Economic productivity. All data were statistically analyzed by analysis of variance and the Tukey test (1%) for mean comparison, with the software SISVAR. In the conditions of this experiment was carried out, it was possible to verify that the cultivar Jamburana had not only a good agronomic development and economic productivity under organic fertilization but also the best morpho-physiological indexes, showing that this kind of fertilization increases the agronomic effectiveness of this cultivar.
