“…On the other hand, the popular use of plants in the treatment of human diseases, takes into account its comprehensive mode of action, referring in most cases as a set of organs or the physiological systems. For example, the coot (Baccharis trimera Less) and tankage (Plantago major L.) are suitable for the digestive system diseases, without specified the disease of such system (PRADO et al, 2009;ALBERTASSE et al, 2010). According to Velasco and Diaz de Rada (1997), the applied research in community settings is a kind of socio-cultural research that allows systematizing the knowledge to make it useful to the whole society.…”

The objective of this study was to verify the occurrence and use of medicinal herbs in families living in urban areas. The research was carried out in five cities in the "Planalto Serrano" region of Santa Catarina State, Brazil. The first family was indicated by the health department of the municipality and the following were indicated by the previous one, according to snowball methodology. Interviewees ranged from 39 to 78 years old, who cited 84 species of plants to treat 205 diseases. The herbs were collected from yard (50%), garden (20.2%), neighbors (14.5%), field (8.9%), or bought (6.4%). The using of medicinal herbs still persists in families living in urban areas of the south plateau of Santa Catarina State, Brazil. There is a predominance of females as maintainers and concentrated on people over 50 years.Palavras-chave: Medicinal Plants. Healing. Disease. Urban Family. RESUMOO objetivo deste estudo foi verificar a ocorrência e uso de plantas medicinais em familias residentes em áreas urbanas. A pesquisa foi conduzida em cinco cidades da região do Planalto Serrano Catarinense, estado de Santa Catarina, Brasil. O primeiro entrevistado era indicado pelo serviço de saúde do município e os demais indicados pelo anterior, seguindo metodologia de bola de neve. Os entrevistados tinham de 39 a 78 anos de idade, citaram 84 especies de plantas como medicinais para tratar 205 enfermidades humanas. As plantas medicinais utilizadas eram procedentes de hortas (50%), jardins (20,2%), vizinhos (14,5%), campos (8,9) ou compradas (6,4%). O uso de plantas medicinais persistes em familias residentes em áreas urbanas. Há predominio de mulheres como mantenedoras cuja idade se concentra acima de 50 anos.

“…In order to reduce the microbiological content, this method of gamma irradiation does not leave residues that can be harmful to workers or consumers. The use of 60 Co also proved an effective technique in reducing pollution or contamination of the fungal flora of medicinal plants [22].…”

“…Interestingly, in different experimental conditions, characterized by different plant species, biological materials and therefore different treatment conditions also need to confirm the chemical stability of the sample, as well as the reduction or inactivation of microbial load contained therein [22][23][24].…”

Lectin Cramoll-1,4, obtained from Cratylia mollis seeds (beans camaratu) was structurally characterized, biologically and pharmacologically, but its use as a biopharmaceutical is not well documented. The objective of this study is to propose a biopharmaceutical formulation lectin Cramoll-1,4, test their hemagglutinating properties in vitro as well as the use of gamma radiation as a continuous process of decontamination formulation. It was made of the extraction and purification Cramoll-1,4, was developed a gel formulation using Carbopol  as a vehicle, at concentrations of 50, 100, 200, 300 and 600 µg was irradiated with 60 Co gamma rays in a dose of 7.549 kGy·h -1 . The proposed formulation at a concentration of 300 µg produced an increase in the hemagglutinating units Cramoll-1,4 due to the synergistic effect caused by gamma radiation. Considering the diverse use of lectins, specific molecular and structural factors, as well as changes resulting from its formulation, concentration, irradiation and route of administration is of utmost importance to continue the studies in vitro, for subsequent application in vivo to characterize the physiological and molecular processes involved in the response and cellular effects.

RESUMOUm dos problemas mais sérios que confrontam a qualidade do arroz é a presença de fungos produtores de micotoxinas, principalmente as espécies pertencentes aos gêneros Aspergillus, Penicillium e Fusarium. Neste estudo, objetivou-se verificar os níveis de aflatoxinas e identificar a população fúngica associada a grãos de arroz beneficiado e comercializado em Belo Horizonte e algumas cidades do sul do estado. Foram analisadas um total de 60 amostras de arroz: orgânico, parboilizado, integral, polido, sendo a incidência de aflatoxinas verificada em uma amostra. Os resultados demonstraram que as espécies aflatoxigênicas identificadas foram A. parasiticus e A. flavus. Utilizando Cromatografia Líquida de Alta Eficiência para avaliar a incidência de aflatoxina em arroz, apenas uma apresentou contaminação de 1,2 ìg Kg -1 . Apesar da presença de fungos aflatoxigênicos, as amostras não apresentaram níveis preocupantes de aflatoxinas que pudessem colocar em risco a segurança do produto e a saúde dos consumidores. Termos para indexação: Aflatoxinas, alimentos, Aspergilus flavus, Aspergillus parasiticus. ABSTRACTOne of the most serious problems facing the quality of rice is the presence of mycotoxin-producing fungi, especially the species belonging to the genera Aspergillus, Penicillium and Fusarium. The objective of this study was to check the levels of aflatoxins and identify the fungal population associated with grains of rice received and sold in Belo Horizonte and some cities in the southern state. We analyzed a total of 60 samples of rice: organic, parboiled, full, polished, and the incidence of aflatoxins found in a sample. The results showed that the aflatoxigenic species identified were A. parasiticus and G2 and A. flavus. Using high performance liquid chromatography to assess the incidence of aflatoxin in rice, only one showed a contamination of 1.2 ìg kg-1. Despite the presence of aflatoxigenic fungi, the samples showed no worrying levels of aflatoxin that could endanger the safety of the product and consumer health.
