RESUMOAs enteroparasitoses são infecções causadas por parasitas intestinais que constituem um dos grandes problemas de saúde pública em todo o mundo, sofrendo variações quanto à região de cada país e tendo sua maior prevalência vinculada a áreas que se apresentam com condições higiênico-sanitárias precárias. O objetivo deste estudo foi verificar a prevalência de enteroparasitoses em crianças de creches da rede pública e privada de Santo Ângelo-RS. Foram coletadas 51 amostras de fezes de escolares com idades entre 1 e 3 anos, no período de março a maio de 2016, utilizando-se o método de Ritchie para análise. Além disso, foram verificados por meio de um questionário fatores socioeconômicos e aspectos relacionados à higiene, caracterizando um estudo observacional, transversal e prospectivo. Das 51 amostras analisadas, foi registrada uma prevalência de parasitoses de 18%, 16% referentes às creches públicas e 2% às creches particulares. Os parasitas encontrados foram Endolimax nana (67%), Giardia lamblia (22%) e Trichuris trichiura (11%). As crianças do sexo masculino apresentaram uma frequência de parasitismo de 78%, o que diferiu da frequência observada entre as crianças do sexo feminino, que foi de 22%. Os resultados indicam valores menores que os encontrados na literatura, entretanto o risco de contaminação e incidência de novos casos está presente na comunidade. Assim sendo, há necessidade da efetivação de práticas educacionais que possam instruir a população para a prevenção de parasitoses e para a conscientização das pessoas, principalmente em relação à educação sanitária. Além do mais, o exame parasitológico de fezes pode ser realizado rotineiramente para controle dessas infecções. Palavras-chave:Crianças. Enteroparasitoses. Creches.
Healing films provide excellent results in the adjuvant treatment of injuries. Its association with plant extracts allows the achievement of therapeutic activities, favoring skin regeneration. This study aimed to develop pullulan films incorporated with an extract from the aerial parts of Cyclospermum leptophyllum to be used as healing dressings and to evaluate their morphological and physicochemical characteristics and their potential antioxidant activity. Polymeric films in the proportion of 4% PU (m/v) and 15% plant extract and control films composed only of the polymer matrix were produced using the casting method. The films were evaluated for thickness, visual aspects, solubility, water vapor permeability, swelling, degradation, and antioxidant activity. They showed good appearance and flexibility but heterogeneity due to the precipitation of components. A high degree of solubility and swelling was observed, and despite its rapid dissolution in contact with water, the formation of a hydrogel can enable greater adherence to wounds. The films have controlled water vapor transmission, that allows gas exchange. A DPPH radical inhibition rate of 17.23% was obtained, proving its antioxidant activity. Therefore, the biofilms produced have healing potential, which can be better studied in the future through tests demonstrating antimicrobial, and anti-inflammatory activities.
The skin acts as a protective barrier for the body. Significant functional limitations can occur when damaged, such as pain and infections. This study aims to develop hydroxypropyl methylcellulose (HPMC) films incorporated with Ocimum basilicum L. (OB) extract for wound healing. The plant extract was prepared, followed by production and morphological evaluation of the films determining, for example, water vapor transmission, swelling index, solubility, and antioxidant activity. The films were macroscopically homogeneous, transparent, flexible, and resistant, with an average thickness of 157 μm. They also showed high hydrophilicity due to the polarity of the polymer, soluble in aqueous media, with a good degree of swelling (1.254 % for HPMC + OB 15 %) and good permeability to water vapor (1.467% for the control film), with a light decrease after incorporation of the extract. However, adding the extract increased the antioxidant activity significantly, around 50%, compared to the control film. Thus, it proves to be a promising dressing for wound healing due to the good physical characteristics of the polymer, combined with the antioxidant activity of the extract.
