ABSTRACT
RESUMO O estudo objetivou conhecer o processo de trabalho dos enfermeiros da atenção primária em relação à Política Nacional de Plantas Medicinais e Fitoterápicos. O referencial foi baseado em Guareschi e Kleinman. A abordagem foi qualitativa, descritiva. Fizeram parte dos estudos enfermeiros de 21 municípios da região Sul do estado do Rio Grande do Sul. Os dados foram coletados por questionário autoadministrado, no período de junho a agosto de 2013. A análise seguiu a proposta operativa de Minayo, emergindo dois temas: processo de trabalho dos enfermeiros e a Política Nacional de Plantas Medicinais e Fitoterápicos; viabilização desta na atenção primária. Observou-se o desconhecimento da política, apesar de ter sido constatado a indicação de plantas medicinais no processo de trabalho. A política é viável quando o enfermeiro organiza grupos, coloca em prática o diálogo interdisciplinar, e contempla a questão dos aspectos culturais do usuário.
ABSTRACT This study aimed to understand nurses’ work processes in primary health care in relation to the National Politics of Medicinal Plants and Phytotherapies. The referential was based on Guareschi and Kleinman. The approach was qualitative and descriptive. Nurses from 21 towns of Southern Rio Grande do Sul participated. Data collection was a self-administrated questionnaire, in the period of June to August of 2013. The analysis followed Minayo’s operative proposal, two themes emerged: nurses’ work processes and the National Politics of Medicinal Plants and Phytotherapies and the viability of this in primary health care. The ignorance of the policy, but they indicate medicinal plants in the work process. The policy is practicable, when the nurses make groups, put the interdisciplinary dialogue in practice and contemplate the users’ cultural aspects.

Introduction: The description of development of human kidney given in various textbooks doesn’t include detail microscopic appearance of kidney at various fetal ages. So an attempt was made in this study to gather information on this topic. Material and methods: The present study was carried out on 15 human fetuses of known gestational age (GA). The sections of kidney were processed and were stained using Hematoxylin and Eosin. Results: At 12th week of GA various stages of developing glomeruli were observed in the substance of the kidneys. In the cortex, various cut sections of the tubules were observed without any differentiation as proximal (PCT) and distal tubules (DCT). The second trimester section showed well differentiated the PCT and DCT by 16th week. Distinct brush border was observed in PCT by the 16th week. Immature duct system was observed in the medulla. The nephrogenic zone was appreciated till 36 weeks. By 28 th week the sections of DCT were observed adjacent to the renal corpuscles indicating the developing juxtaglomerular apparatus. Conclusion: As it is essential to know the developmental morphology of kidney, the present study explains every component of it in detail.
ABSTRACT
RESUMO O óleo volátil da melaleuca (Melaleuca alternifolia Maiden & Betche, Cheel) possui atividade antimicrobiana podendo causar efeitos sobre as plantas. Avaliou-se a inibição do óleo em Cercospora beticolaSacc., e seu efeito no aumento da produção e qualidade de raízes de beterraba. As doses foram de 0,13; 0,67; 0,80 e 1,00% do óleo, além das testemunhas composta pelo meio de cultura Batata Dextrose Ágar (BDA) no experimento in vitro, e água no experimento in vivo. As plantas foram pulverizadas duas vezes por semana. O delineamento foi inteiramente casualizado, com 4 repetições, e as médias foram comparadas pelo teste Tukey a 5% de probabilidade. O índice de infecção das folhas foi determinado por escala diagramática além do peso e diâmetro das raízes. Os resultados de inibição do crescimento micelial para as doses do óleo foram 0; 56; 87; 83 e 99%, e os índices de infecção: 77,08; 35,62; 21,04; 19,37 e 20,00%, respectivamente, para a testemunha e as doses 0,13; 0,67; 0,80 e 1,00% do óleo. Somente na concentração de 0,80% o óleo proporcionou relação positiva entre o ganho de peso e o diâmetro das raízes. O óleo de Melaleuca foi eficaz no controle de C. beticola e, como consequência, houve produção de raízes de beterraba com melhor desenvolvimento.
ABSTRACT The volatile oil from Melaleuca (Melaleuca alternifolia Maiden & Betche Cheel.) has antimicrobial properties and can promote several effects on plant cultivation. The aim of this study was to evaluate the inhibition of the oil in Cercospora beticola Sacc. and if it favors the growth and development of beet root. The doses were 0.13, 0.67, 0.8 and 1% of oil, besides the control PDA (potato-dextrose-agar) in vitro (laboratory condition) and with water as treatment control in vivo (field conditions). The plants were sprayed twice a week. The treatments were completely randomized and the averages were compared using the Tukey test at 5%. The infection rate of leaves was measured by diagrammatic scale besides the weight and diameter of tubers. The inhibition results of the radial growth by oil treatments were 0; 56, 87, 83 and 99%, while the infection rate showed: 77.08, 35.62, 21.04, 19.37 and 20% respectively to the control and to the oil concentration of 0,13; 0,67; 0,80 e 1,00%. Only at concentration of 0.8% the tea tree oil showed a positive relationship between tuber´s weight and tuber´s diameter gains. It can be concluded that tea tree oil is effective to controlling C. beticola, and also promotes an increase on development in beet tubers.

Uma busca foi realizada na literatura, visando sumarizar as pesquisas realizadas e obter informações acerca da utilização de plantas medicinais no processo de cicatrização de feridas. Utilizaram-se os descritores: Plantas Medicinais e Cicatrização de Feridas e seus equivalentes em inglês e espanhol, com o operador booleano "AND" em três bases eletrônicas de dados (PubMed, LILACS e COCHRANE). Foram selecionados 57 artigos para compor a revisão. Os resultados apontam que um total de 52 plantas medicinais e um composto de ervas foram estudados experimentalmente ou clinicamente, quanto aos seus efeitos no auxílio do processo de cicatrização, sendo que a maioria (88,5%) apresentou eficácia. Com isso, verifica-se que a utilização de plantas medicinais trata de importante alternativa no tratamento de feridas, que começa a fazer parte da atenção à saúde brasileira, o que sugere novos estudos de comprovação clínica, custos, e benefícios e a constante atualização acerca das publicações realizadas.
It was done a literature search aiming to sumarize earlier conducted researches and in order to obtain information on the use of medicinal plants in wound healing process. The descriptors used were as follows: Medicinal Plants and Wound Healing and their equivalents in English and Spanish with the Boolean operator "AND" in three electronic databases (PubMed, LILACS and COCHRANE). Fifty seven articles were chosen to compose the review. The findings from a total of fifty two medicinal plants and one herbal compound that were experimentally or clinically studied in respect to their effects in wound healing process indicate that the majority of them (eighty eight point five per cent) showed efficacy. Thus, it can be seen that the use of medicinal plants is an important alternative in wounds treatment that becomes part of Brazilian health care, suggesting further studies of clinical evidence, costs and benefits and constantly updating on produced publications.
