The outdoor cultivation (ditches) of Agaricus blazei was evaluated in the protected natural area (APA) of the mountainous region of Baturité on three types of casing soils (A, B and C). Casing soil A (horizon A) of the local soil was used (Alfisol). Casing B was obtained with a mixture of 30% of eucalyptus charcoal (1-2 cm of length) and 70% of horizon B of the local soil. Casing C was composed of 25% of vermiculite, 25% of coconut fiber and 50% of coarse sand. Temperature, relative humidity and pluviometric rates were monitored. The physical-chemical properties of the three casing soils were analyzed. The effect of the casing soil on the number and weight of the mushrooms, productivity, yield and biological efficiency of A. blazei were evaluated. The yield, productivity, biological efficiency and number of mushrooms were higher when using soil A. The highest productivity for soil A was attributed mainly to the physical characteristics, which were considered more appropriate for the cultivation, in addition to the high pluviometric rates and relative humidity. The productivity with soil A (9.62%) is comparable with the average productivity obtained in Brazil, meaning that the cultivation of A. blazei in this APA may have good perspectives for cultivation.

De acordo com a Organização Mundial da Saúde, a leishmaniose é ainda uma das doenças mais negligenciadas do mundo, afetando principalmente países pobres e em desenvolvimento. As leishmanioses podem, de acordo com a forma de acometimento do homem, dividir-se em dois grandes grupos: visceral e tegumentar. As estatísticas mostram que cerca de 350 milhões de pessoas são consideradas com risco de contrair leishmaniose, e cerca de dois milhões de novos casos ocorrem anualmente. O número de casos de leishmaniose tegumentar no Brasil em 2011 foi de 15.731. É considerada uma doença negligenciada uma vez que os fármacos de escolha são preparações à base de antimoniais, sendo os mesmos desde sua descoberta em 1912. Além disso o tratamento é longo, doloroso e altamente tóxico, assim levando os pacientes muitas vezes a desistirem antes do término previsto. O presente trabalho tem como objetivo fazer uma revisão bibliográfica a partir do banco de dados do PubMed e Scielo sobre novas pesquisas na área de fármacos e novos tratamentos para leishmaniose cutânea entre os anos de 2007 e 2012.

Prophylactic or therapeutic treatments administered with medicinal plants and natural products are used in popular medicine of diverse people since prehistoric times to the present days. Species with medicinal properties are increasingly studied in an attempt to understand their possible effects on organisms and their functioning. This study aimed to analyze the effect of the mushroom Agaricus blazei (aqueous extract) in rabbits subjected to experimental hypercholesterolemia. The animals were divided into two groups (control and treated with the mushroom) whose experimental protocol was divided into three phases: Phase 1, the animals were fed a normal diet to evaluate the physiological level of cholesterol; phase 2, the animals were fed a supplemented diet to induce hypercholesterolemia and in phase 3, the animals of control group continued to take high-cholesterol diet and the animals of treated group high-cholesterol diet including treatment with the mushroom. Weekly, after fasting of 14 hours, blood samples were collected from the animals and its plasma was stored for later measurement of plasmatic cholesterol. In the first phase, the cholesterol level was, on average, 31,30  7,34 mgdL-1. In the second phase, there was a significant increase (p<0,05) in cholesterol level of both groups. During the last phase of the experiment, the mushrooms didn’t cause reduction in plasmatic cholesterol of treated rabbits, however, prevent disease progression, maintaining the cholesterol level established at the beginning of treatment, whereas, in the control group, total serum cholesterol increased significantly at this stage
