EVALUATION OF ANTIMICROBIAL AND CYTOTOXIC ACTIVITIES OF PLANT EXTRACTS FROM SOUTHERN MINAS GERAIS CERRADO

The antimicrobial activity of plant hidroethanolic extracts on bacteria Gram positive, Gram negative, yeasts, Mycobacterium tuberculosis H37 and Mycobacterium bovis was evaluated by using the technique of Agar diffusion and microdilution in broth. Among the extracts evaluated by Agar diffusion, the extract of Bidens pilosa leaf presented the most expressive average of haloes of growth inhibition to the microorganisms, followed by the extract of B. pilosa flower, of Eugenia pyriformis' leaf and seed, of Plinia cauliflora leaf which statistically presented the same average of haloes inhibitory formation on bacteria Gram positive, Gram negative and yeasts. The extracts of Heliconia rostrata did not present activity. Mycobacterium tuberculosis H37 and Mycobacterium bovis (BCG) appeared resistant to all the extracts. The susceptibility profile of Candida albicans and Saccharomyces cerevisiae fungi were compared to one another and to the Gram positive Bacillus subtilis, Enterococcus faecalis and the Gram negative Salmonella typhimurium bacteria (p > 0.05). The evaluation of cytotoxicity was carried out on C6-36 larvae cells of the Aedes albopictus mosquito. The extracts of stem and flower of Heliconia rostrata, leaf and stem of Plinia cauliflora, seed of Anonna crassiflora and stem, flower and root of B. pilosa did not present toxicity in the analyzed concentrations. The highest rates of selectivity appeared in the extracts of stem of A. crassiflora and flower of B. pilosa to Staphylococcus aureus, presenting potential for future studies about a new drug development

CONSULTA DE ENFERMAGEM A CLIENTE HIPERTENSO: ANÁLISE DE UM INSTRUMENTO UTILIZADO E PROPOSTA DE UM NOVO MODELO

As autor-as tecem considerações preliminares sobre Consulta de Enfermagem e analisam o instrumento utilizado na consulta a clientes hipertensos de um hospital especializado em cardiología. Através desta análise foi constatada a necessidade de adequação do instrumento para a clientela específica. Acredita-se que a adequação do instrumento seja importante elemento facilitador para a execução da Consulta de Enfermagem e para melhor direcionamento das ações pela enfermeira. Após prática vivenciada pelas autoras, foi proposto um modelo que consta de histórico de enfermagem, levantamento de problemas, plano de orientação e de cuidados de enfermagem e folha de evolução. Para que este modelo seja utilizado de modo uniforme, foi elaborado um manual de orientação.This is a preliminary study on nursing consultation for hypertensive patients and analysis of the instrument used in a cardiology hospital. The development of an adequate instrument for this kind of patients, with a specif model for assessment, orientation plan, nursing care plan and evolution, was followed by the preparation of an orientation guide to be used by nurses, so an uniformed way of registration could be obtained
