In South American folk medicine members of the genus Myrciaria are used for the treatment of malaria, diarrhoea, asthma, inflammation and post-partum uterine cleansing. The aim of this work was to evaluate its antileishmanial properties (in vitro) of essential oil derived from leaves of Myrciaria plinioides D. Legrand, a plant species that is native in South of Brazil. The essential oil was obtained by hydro-distillation using fresh leaves of M. plinioides. The chemical composition of this essential oil (MPEO, M. plinioides essential oil) was determined by gas chromatography coupled to mass spectrometry (GC-MS). MPEO was assayed in vitro for antileishmanial properties against promastigotes of Leishmania amazonensis and Leishmania infantum, and for cytotoxicity against murine peritoneal macrophages. The MPEO comprised 66 components and was rich in oxygenated sesquiterpenes (82.66%) containing spathulenol (21.12%) as its major constituent. The MPEO was effective against L. amazonensis with IC50 value of 14.16 ± 7.40 µg/mL, while against L. infantum the IC50 value was higher with 101.50 ± 5.78 µg/mL. The MPEO showed significant activity against L. amazonensis, and presented a selectivity index (SI) of 6.60. The results suggest that the essential oil from leaves of M. plinioides is a promising source for new antileishmanial agents against L. amazonensis.

O objetivo deste estudo foi avaliar o estoque domiciliar de medicamentos em comunidades atendidas pela Estratégia de Saúde da Família (ESF) em município localizado no Sul do Brasil. Foram amostrados 10% dos domicílios de cinco ESF. Os dados foram coletados por Agentes Comunitários de Saúde (ACS) através de questionário adaptado. A idade média dos entrevistados foi de 42 anos e dos moradores foi de 16 anos, destes 51% eram mulheres. Foi observada renda de 1 a 3 salários mínimos (69,1%), e escolaridade de 0 a 4 anos de estudo (42%). Dos domicílios visitados, 98,7% apresentavam pelo menos um medicamento estocado. Dos 533 lugares de guarda averiguados, 43,5% estava exposto ao calor, 39,6% a umidade, 16,5% a luz. Dos 2.717 medicamentos encontrados, 6,9% estavam vencidos, 35,3% não estavam dentro da embalagem secundária, quando esta se aplica, 67,9% não continham a presença de bula. Os fármacos analgésicos foram os mais prevalentes no estoque (21%). Os resultados nos levam a concluir que há necessidade de equipe multiprofissional para a promoção de saúde e a racionalização dos estoques domiciliares de medicamentos, sendo que o ACS é um profissional indispensável para a promoção do uso racional de medicamentos.

The scope of this study was to investigate the in-house stock of medication in communities served by the Family Health Strategy (FHS) in a city located in the south of Brazil. A sample of 10% of households in five FHS areas was studied. Data were collected by Community Healthcare Workers using the adapted Fernandes questionnaire (2000). The mean age of the interviewees was 42 years and of the residents was 16 years, 51% of which were female. Low income (1 to 3 minimum wages) was observed (69.1%), and low education levels (0 to 4 years of study) (42%). Of the households visited 98.7% had at least one medication in stock. In 533 of the storage places located, 43.5% of such places were exposed to heat, 39.6% were exposed to humidity and 16.51% to light. Of the 2,717 medicines found, 6.9% were past the validity date, 35.3% were not in the secondary wrapping and 67.9% were without the patient information leaflet. Analgesics were the most common medications in in-house stock (21%). This study revealed the need for a multi-professional team to promote health and the rationalization of in-house stock since the Community Healthcare Worker is an indispensable professional to promote the rational use of medication.

A Assistência Farmacêutica se preocupa com ações desenvolvidas pelo farmacêutico ou outros profissionais com o propósito de promover, proteger e restaurar a saúde. Medicamentos são ferramentas essenciais nesse processo, que se concentra no acesso e no uso racional de fármacos. Este estudo objetivou a avaliação da Assitência Farmacêutica suprida pela Secretaria Municipal da Saúde no Vale do Taquari, no Rio Grande do Sul. Com esse propósito, 2.794 usuários das farmácias públicas foram entrevistados e analisaram-se os dados usando estatística descritiva. Os usuários das farmácias públicas eram, principalmente, mulheres e indivíduos com baixo nível educacional e financeiro. Na média, 2,41 fármacos eram prescritos por prescrição médica e 1,72 destes foram obtidos. Do total de medicamentos prescritos, 76,5% estava inscritos na lista de medicamentos padrão do município (SDL). A medicação foi prescrita pelo nome genérico em 81,8% dos casos. Antibióticos e injeções foram prescritas em 11,9% e 4,0% das prescrições, respectivamente. O acesso dos usuários à informação é parcial, o que pode prejudicar a adesão ao tratamento. Dessa forma, é possível concluir que a revisão do serviço é necessária para que seja eficaz.

Pharmaceutical assistance concerns actions developed by the pharmacist and other professionals with the purpose of promoting, protecting and restoring health. Medications are an essential tool in this process that focuses on the access to, and the rational use of, drugs. This study is aimed at evaluating the Pharmaceutical Assistance provided by Municipal Health Offices in the Taquari Valley, Rio Grande do Sul. For this purpose, 2,794 users of public pharmacies were interviewed and data was analyzed using descriptive statistics. The users of the public pharmacies were mainly female and individuals with low educational level and income. On average, 2.41 drugs were prescribed per medical prescription and 1.72 of these were procured. Out of the total medicines prescribed, 76.5% were listed in the municipal standard drug list (SDL). Medication was prescribed by its generic name in 81.8% of the prescriptions. Antibiotics and injections were prescribed in 11.9% and 4.0% of the prescriptions, respectively. Users' access to information is partial, which can impair adherence to the treatment. Thus, it is possible to conclude that review of the service is necessary for it to be effective.

Cinco glicosídeos foram isolados a partir das folhas de P. alata. Após extensivas análises espectroscópicas, as estruturas 1-5 foram identificadas como sendo o 3-O-beta-D-glicopiranosil-estigmasterol (1), o ácido 3-O-beta-D-glicopiranosil-oleanólico (2), o ácido 3-O-beta-D-glicopiranosil-(1->3)-beta-D-glicopiranosil-oleanólico (3), o ácido 3-O-beta-D- glicopiranosil-(1->2)-beta-D-glicopiranosil-oleanólico (4) e 9,19-ciclolanost-24Z-en-3beta,21,26-tri-hidróxi-3,26-di-O-gentiobiose (5). Adicionalmente, foram analisados, através de CCD, extratos hidroetanólicos de espécies de Passiflora existentes no sul do Brasil (P. actinia, P. caerulea, P. edulis var. flavicarpa, P. elegans, P. foetida, P. misera e P. tenuifila). A acumulação de saponinas foi verificada somente em Passiflora alata.

The structures 1-5 were obtained through extensive spectral analyses as 3-O-beta-D-glucopyranosyl-stigmasterol (1), 3-O-beta-D-glucopyranosyl-oleanolic acid (2), 3-O-beta-D-glucopyranosyl-(1->3)-beta-D-glucopyranosyl-oleanolic acid (3), 3-O-beta-D-glucopyranosyl-(1->2)-beta-D-glucopyranosyl-oleanolic acid (4) and 9,19-cyclolanost-24Z-en-3beta,21,26-trihydroxy-3,26-di-O-gentiobiose (5). Comparison of the TLC profiles of the hydroethanolic extracts from leaves of other Passiflora species found in the south of Brazil (P. actinia, P. caerulea, P. edulis var. flavicarpa, P. elegans, P. foetida, P. misera and P. tenuifila) showed that only P. alata presented saponin accumulation.
