ABSTRACT

RESUMO Objetivo: Considerando a importância dos produtos naturais de uso tradicional, o trabalho propôs a avaliação de parâmetros de qualidade e atividade antimicrobiana in vitro do gargarejo produzido no Centro de Educação Popular (Cenep), Nova Palmeira (PB), e utilizado para o tratamento de afecções da orofaringe e amígdalas. Metodologia: Três amostras de gargarejo foram analisadas para avaliar o aspecto microbiológico sendo realizada a contagem de micro-organismos viáveis, por semeadura em profundidade. Materiais e métodos: A avaliação da atividade antimicrobiana in vitro contra S. pyogenes foi realizada utilizando o método de difusão em ágar e os parâmetros físico-químicos determinados foram pH, resíduo seco, densidade, bem como a caracterização fitoquímica. Resultados: Apresentaram contagem microbiana dentro dos limites estabelecidos pela Farmacopeia. A atividade antimicrobiana contra S. pyogenes apresentou halos de inibição variando de 10,5 a 18,6 mm para amostra diluída e pura, respectivamente. Os parâmetros físico-químicos apresentaram pH 4,39 ± 0,16; o resíduo seco de 13,4 % a 15,4 %; e a densidade de 1,013 ± 0,010. O perfil fitoquímico foi caracterizado pela presença de taninos, alcaloides e flavonoides. Conclusões: O gargarejo apresentou-se adequado para uso, tendo em vista os parâmetros microbiológicos, físico-químicos, fitoquímicos apresentados, bem como a comprovação da eficácia antimicrobiana adequada ao uso terapêutico proposto.


SUMMARY Aim: Considering the importance of natural products of traditional use, the work proposed the evaluation of quality parameters and in vitro antimicrobial activity of the gargle produced at the Popular Education Center (Cenep), Nova Palmeira (PB), and used for the treatment of oropharynx and tonsil disorders. Methodology: Three gargle samples were analyzed, in order to evaluate the microbiological aspect, the count of viable microorganisms was performed, by pour plate method. Materials and methods: The evaluation of antimicrobial activity in vitro against S. pyogenes was performed using the agar diffusion method and the physicochemical parameters determined were pH, dry residue, density, as well as phytochemical characterization. Results: They had microbial counts within the limits established by the pharmacopoeia. The antimicrobial activity against S. pyogenes had inhibition halos ranging from 10.5 to 18.6 mm for diluted and pure samples, respectively. The physical-chemical parameters showed pH 4.39 ± 0.16; the dry residue of 14.43 ± 1.00; and the density of 1.013 ± 0.010. The phytochemical profile was characterized by the presence of tannins, alkaloids and flavonoids. Conclusion: Thus, the gargle was suitable for use, considering the microbiological, physical-chemical, phytochemical parameters presented, as well as the proof of antimicrobial efficacy suitable for the proposed therapeutic use.


RESUMEN Objetivo: Considerando la importancia de los productos naturales de uso tradicional, el trabajo propuso la evaluación de los parámetros de calidad y la actividad antimicrobiana in vitro de la gárgaras producidas en el Centro de Educación Popular (Cenep), Nova Palmeira (PB), y utilizadas para el tratamiento de los trastornos de la orofaringe y las amígdalas. Metodología: Se analizaron tres muestras de gárgaras para evaluar el aspecto microbiológico, se realizó el recuento de microorganismos viables, sembrando en profundidad. Materiales y métodos: La evaluación de la actividad antimicrobiana in vitro contra S. pyogenes se hizo mediante el método de difusión en agar y los parámetros fisicoquímicos determinados fueron pH, residuo seco, densidad, así como caracterización fitoquímica. Resultados: Hubo recuentos microbianos dentro de los límites establecidos por la Farmacopea. La actividad antimicrobiana contra S. pyogenes tenía halos de inhibición que oscilaban entre 10,5 y 18,6 mm para muestras diluidas y puras, respectivamente. Los parámetros físico-químicos mostraron un pH que oscila entre 4,39 ± 0,16; el residuo seco del 14,43 ± 1,00; y la densidad de 1,013 ± 0,010. El perfil fitoquímico se caracterizó por la presencia de taninos, alcaloides y flavonoides. Conclusión: Por lo tanto, la gárgara demostró ser adecuada para su uso, considerando los parámetros microbiológicos, fisicoquímicos, fitoquímicos presentados, así como la prueba de la eficacia antimicrobiana adecuada para el uso terapéutico propuesto.

ABSTRACT

Toxoplasmosis is caused by Toxoplasma gondii, which is particularly relevant in pregnant women, due to the risk of congenital infection. The aim of this study was to study the serological profile of pregnant women and analyze some factors related to infection in this group. A descriptive and retrospective study was performed analyzing the results of 356 pregnant women in the Mixed Health Unit of Jaçanã-RN from 2009 to 2014. Results of serological tests for IgG and IgM anti-T. gondii antibodies were provided by LACEN-RN. The chi-square test (χ2) was calculated being considered statistically significant for p<0.05. The results showed that: 59% of the pregnant women tested presented serology IgG anti-T. gondii reagent (IgG+) and IgM anti-T. gondii non-reactive (IgM-), 0.6% reagent for both (IgG+ and IgM+) and 40.4% susceptible to infection (IgG- and IgM-). 71.3% of the women were tested in the first trimester of pregnancy; the 20-29 years of age range was the most prevalent (62.5%) and the 11-19 years of age range was the most susceptible (47%). The rural women had the highest incidence of positive serology (60.2%) and those from the urban area were the most susceptible (40.7%). There was no statistical association between serology and the age group (p=0.282) and origin (p=0.881) variables. There is need for investment in prenatal care and health education for the population about toxoplasmosis
