ABSTRACT
RESUMO Objetivo: Compreender a percepção acerca da vulnerabilidade às IST/HIV/AIDS entre as adolescentes residentes em assentamento urbano de uma capital do Brasil Central. Material e Método: Estudo descritivo e exploratório, com abordagem qualitativo, realizado em assentamento da periferia de uma capital do Brasil Central. De um total de 407 adolescentes da única instituição do assentamento, 107 foram considerados para o estúdio, 20 deles assistiram à consulta hebiátrica até atingir a saturação dos dados, a amostra final foi constituída por 16 adolescentes. Os dados foram obtidos por meio de entrevistas semiestruturadas. A análise de conteúdo foi utilizada para tratar os dados, sob a ótima da Teoria das Representações Sociais. Resultados: Emergiram as seguintes categorias temáticas: sentimento de invulnerabilidade às IST/HIV/AIDS; relação de gênero e vulnerabilidade às IST/HIV/AIDS e sexualidade, rede social e vulnerabilidade às IST/HIV/AIDS. Conclusão: As adolescentes assentadas são marcadas pela subalternidade de gênero, que muitas vezes é negada e naturalizada pelos ideais de legitimação de desigualdade entre os sexos.
ABSTRACT Objective: To understand the perception about the vulnerability to STI/HIV/AIDS among female adolescents living in an urban settlement in a city of Central Brazil. Materials and Methods: Descriptive and exploratory study, with qualitative approach, carried out in an urban settlement on the outskirts of a capital city in central Brazil. From a population of 407 adolescents from the only educational institution in the settlement, 107 were considered for the study. Of these, 20 went for hebiatric consultation and, until data saturation was reached, the final sample consisted of 16 adolescents. Data were obtained through semi-structured interviews. Content analysis was used to treat the data from the perspective of the Theory of Social Representations. Results: The following thematic categories emerged: feeling of invulnerability to STI/HIV/AIDS; gender relationship and vulnerability to STI/HIV/AIDS and sexuality, social network and vulnerability to STI/HIV/AIDS. Conclusion: Adolescent girls from the settlement are marked by gender subordination, which is often denied by them and naturalized by the ideals of legitimizing gender inequality.
RESUMEN Objetivo: Comprender la percepción sobre la vulnerabilidad a las IST/VIH/SIDA entre las adolescentes que viven en un asentamiento urbano en una capital del centro de Brasil. Material y Método: Estudio descriptivo y exploratorio, de abordaje cualitativo, realizado en un asentamiento urbano de la periferia de una capital de Brasil central. De un total de 407 adolescentes de la única institución del asentamiento, 107 fueron considerados para el estudio, de ellos, 20 acudieron a consulta hebiátrica y hasta que se alcanzó la saturación de datos, la muestra final quedó constituida por 16 adolescentes. Los datos se obtuvieron a través de entrevistas semiestructuradas. El análisis de contenido se utilizó para tratar los datos, bajo el óptimo de la Teoría de las representaciones sociales. Resultados: Surgieron las siguientes categorías temáticas: sensación de invulnerabilidad a las IST/VIH/ SIDA; Relación de género y vulnerabilidad a las IST/VIH/SIDA y Sexualidad, red social y vulnerabilidad a las IST/VIH/SIDA. Conclusión: Las adolescentes asentadas están marcadas por la subordinación de género, que a menudo es negada y naturalizada por los ideales de legitimar la desigualdad entre los sexos.

Litchi chinensis Sonn seeds and pericarp are used in popular medicine as antioxidant, anticancer, antiviral, analgesic, antipyretic, immunomodulatory agent and others. However, literature on litchi leaves extract and the main compound procyanidin A2 (PA2) activities are scarce. Here, we investigated the anti-inflammatory activity of L. chinensis leaves extract and the main compound PA2 using in vitro and in vivo assays. We used the pleurisy and air-pouch model induced by carrageenan, substance P, histamine, bradykinin or lipopolysaccharide (LPS) in mice. The PA2 effects were also evaluated using carrageenan-induced pleurisy and LPS-induced air-pouch. In addition, LPS-induced NO2- production and cytotoxicity were quantified using peritoneal neutrophils recruited by oyster glycogen previously treated with L. chinensis extract or PA2. Animals orally treated with L. chinensis leaves extract exhibited a reduction on carrageenan-induced paw edema. Furthermore, the extract reduced the leukocyte migration and the protein leakage in the pleurisy model induced by carrageenan, substance P, histamine and bradykinin. The main compound in the leaves extract, PA2 reduced the paw edema and cell migration into the carrageenan-inflamed tissue. The data obtained in the LPS-induced air pouch model show that the extract and PA2 inhibit the in vivo neutrophil migration. In addition, the leaves extract and PA2 did not affect the neutrophil viability and reduces NO2- production. Taken together, the data herein obtained showed the modulatory actions of L. chinensis leaves extract on leukocyte migration to inflamed tissue, suggesting its therapeutic application to acute inflammatory process. In addition, it may be supposed that PA2 could be related with these actions, as it is the main compound of L. chinensis leaves extract
