RESUMO
1. The objectives of this study were to establish the use of the fluorophores Hoechst 33342 and propidium iodide for the evaluation of sperm plasma membrane integrity and to identify an adequate hypoosmotic solution for the evaluation of sperm membrane functionality in quails.2. Sperm samples were collected from the vas deferens of nine quails. After initial evaluation, the samples were subjected to a flash-frozen assay. Three treatments with the following proportions of fresh sperm and sperm subjected to flash freezing were prepared as follows: 100:0 (T100), 50:50 (T50), and 0:100 (T0). The hypoosmotic swelling test used distilled water (0 mOsm/l) and fructose solutions (50, 100, and 200 mOsm/l).3. Immediately after recovery, the samples showed 75.6 ± 5.0% motility with vigour of 3.7 ± 0.3 and 96.1 ± 0.5% of the sperm appeared normal. The membrane integrity test showed 62.2 ± 5.2% intact sperm at T100, 29.0 ± 4.1% at T50 and 0.1 ± 0.1% at T0. Moreover, a greater number of reactive sperm (74.7 ± 6.7%) were observed when incubated in distilled water (0 mOsm/l) in comparison to other solutions (P < 0.05).4. The association of fluorescent probes composed of Hoechst 33342 and propidium iodide provided an efficient assessment of the integrity of the plasmatic membrane of quail spermatozoa. However, the study identified that the hypoosmotic swelling test has little predictive value regarding sperm membrane functionality in this species.

O estudo avalia a utilização de plantas medicinais com atividade antimicrobiana pelos usuários do Sistema Único de Saúde do município de Campina Grande- PB, Brasil. Trata-se de um estudo descritivo, transversal, com abordagem quantitativa, cuja amostra constituiu-se de 220 usuários conduzido no período de Agosto de 2008 a Janeiro de 2009. A pesquisa foi realizada através de um roteiro de entrevistas não estruturada. Dentre os participantes do estudo, 65,0% utilizavam plantas medicinais, das quais Punica granatum L., Anacardium occidentale L., e Stryphnodendron adstringens foram as mais citadas. Observou-se que houve prevalência do gênero feminino na utilização. A maioria dos indivíduos obtém plantas medicinais no comércio local utilizando-as por indicação de familiares. Foi observado que 5,0% dos entrevistados afirmam já ter sofrido algum evento adverso decorrente do uso de plantas medicinais. Assim sugere-se que as informações sobre o uso da flora medicinal adquiridas nas comunidades locais, combinadas a estudos químicos/farmacológicos realizados em laboratórios especializados e a capacitação da equipe de saúde favorecerá a implementação da Portaria nº 971/2006, que tem como objetivo a garantia de acesso a plantas medicinais e fitoterápicos com segurança, eficácia e qualidade.
This study evaluates the use of medicinal plants with antimicrobial activity by users of the Unified Health System in Campina Grande Municipality, Paraíba, Brazil. This is a descriptive and transversal study with a quantitative approach, the sample of which consisted of 220 users, and was carried out from August 2008 to April 2009. The research was developed through an unstructured interview process. Among the study participants, 65.0% used medicinal plants, of which Punica granatum L., Anacardium occidentale L. and Stryphnodendron adstringens were most cited. There was prevalence of females. Most individuals obtain medicinal plants in the local market, using them as suggested by relatives. Results indicated that 5.0% of the interviewees stated to have suffered adverse event resulting from the use of medicinal plants. Thus, information about the use of medicinal plants, acquired in local communities, combined to chemical/pharmacological studies performed in specialized laboratories and the qualification of health professionals, will favor the implementation of Decree no. 971/2006, which aims to ensure access to medicinal plants and herbal medicines with safety, efficacy and quality.
