Abstract: Diabetes Mellitus is a universal disease with involvement in the growing world population, and cause of many complications that entail loss in quality of life and ability laborativa of people. The objective of this work was to raise social welfare data (management of Vitória da Conquista-BA), on the impact of customers and their diabetic complications in the generation of benefits and assistance in the period from 2003 to August 2007. Survey was conducted in the database management of the INSS Vitória da Conquista, Bahia. Data were collected from the Single Information System program of Benefits (SUIBE), available from internal computer network (Intranet). Aiming to restrict the cases to only those that would have been consedido benefit as a result of diabetes and its complications or, the search was given, as the International Classification of Diseases, tenth version (ICD-10), the Pan American Health Organization and World Organization Health (WHO). The results showed that the universe of searchable 50798 concerning the management of Vitoria da Conquista, only 334 were found benefits related to diabetes and its complications. In all the benefits studied a marked impact, regardless of sex, with varying degrees of disability generators of various types of benefits with age 40,07-56,00 years. It can be concluded with the attainment of this that the low incidence (0,65%) of benefits arising from diabetes and its complications, it is probably due to underreporting

Abstract: A murcha-de-fusarium, causada pelo fungo Fusarium oxysporum, vem-se tornando uma doen a importante no meloeiro devido às grandes perdas em áreas de produ o no Brasil e no mundo, raz o pela qual o objetivo do presente trabalho foi avaliar a eficácia de extratos etanólicos de partes de Senna alata no controle do crescimento micelial de F. oxysporum isolado de plantas de meloeiro. O delineamento experimental foi inteiramente casualizado, distribuído em esquema fatorial 4 x 6 + 1, sendo o primeiro fator partes da planta (caule, folha, raiz e vagem) e, como segundo, seis concentra es (0,25; 0,50; 50; 75; 250; 500 μg mL-1) mais a testemunha, com quatro repeti es por tratamento. As variáveis avaliadas foram: taxa de crescimento micelial inibi o do crescimento micelial e área abaixo da curva do crescimento micelial. Extratos etanólicos de todas as partes de Senna alata foram eficazes no controle de F. oxysporum. Extratos de raiz e vagem foram os mais eficientes em inibir o crescimento micelial de F. oxysporum, na concentra o 500 μg mL-1. Fusarium wilt, caused by Fusarium oxysporum fungi has become an important melon disease, due to great losses in the production areas in Brazil and in the world. Therefore, the objective of the present work was to evaluate efficacy of ethanolic extracts of Senna alata parts in the control of F. oxysporum micelial growth, isolated of melon plants. The experimental design was entirely randomized distributed in factorial scheme 4 x 6 + 1, being the first factor parts of the plant (stalk, leaf, root, and green bean), and as second, six concentrations (0.25; 0.50, 50, 75, 250, 500 μg mL-1), plus the control, with four repetitions per treatment. The variables evaluated were: rate of mycelial growth, inhibition of the mycelial growth (IGM) and area under the curve of the mycelia growth. Ethanolic extracts of all Senna alata parts were efficient in control of F. oxysporum. Extracts of root and string bean were most efficient in inhibiting the mycelial growth of F. oxysporum, in 500 μg mL-1 concentration.

Abstract: the genus baccharis has a wide distribution in the arid regions of northwestern argentina. one species of this genus, baccharis boliviensis, growths in association with other plant species at los cardones national park, salta province. studies carried out on the spatial distribution of the cacti trichocereus pasacana in relation to available space show that although cacti seeds are abundant beneath baccharis boliviensis canopy, no adult plants are found growing in association with this species, in spite of the requirement of a nurse plant for a successful cacti establishment. aqueous extracts from baccharis boliviensis foliage extracted with hexane, chloroform and ethyl acetate inhibited trichocereus pasacana germination. chloroform was the most effective solvent for extracting the phytotoxic compounds. from this extract we isolated three flavonoids whose structures were determined by spectroscopic methods and tlc in silica gel. the germination bioassay showed that trichocereus pasacana had a differential response to the compounds from the tested extracts. the inhibitory effect was only detected in the chloroformic extract, which suggests a synergistic effect.
