Rosa mosqueta como potencial agente cicatrizante / Rosa mosqueta como agente curativo potencial / Rosehip as a potential healing agent

RESUMO Introdução: O óleo extraído das sementes da Rosa Mosqueta (Rosa aff rubiginosa ou Rosa canina L.) é rico em ácidos graxos insaturados e ácido transretinóico cujas propriedades têm despertado o interesse desse insumo no processo de cicatrização. Objetivo: Realizar um levantamento de estudos sobre a aplicação tópica do óleo de Rosa Mosqueta para cicatrização de feridas. Métodos: A busca foi realizada em bases de dados eletrônicas entre julho e setembro de 2015 por meio dos descritores "Rosa Mosqueta", "wound", "Rosa aff rubiginosa", "healing" ou "Rosa canina", sendo incluídos artigos originais e de revisão. Foram encontradas 7 publicações, sendo uma revisão de literatura, três estudos experimentais não clínicos, um estudo clínico de delineamento não-experimental, um estudo com delineamento quase-experimental e outro com delineamento experimental, porém de baixa qualidade metodológica. Conclusões: Estudos indicam que em lesões de cicatrização por primeira intenção, o óleo deve ser utilizado após 48 h do procedimento. O óleo refinado é mais estável que o óleo bruto e apresenta efeitos terapêuticos mesmo em baixa concentração. No entanto, os estudos clínicos possuem vieses metodológicos que reduzem o nível de evidência e não são suficientes para uma recomendação. Já os estudos não clínicos mostram que o óleo de Rosa Mosqueta pode ter atividade imunomodulatória no leito da ferida e favorecer a deposição de colágeno e organização tecidual(AU)

RESUMEN Introducción: el aceite extraído de las semillas de Rosa mosqueta (Rosa aff rubiginosa ou Rosa canina L.) presenta en su composición ácidos grasos esenciales y ácido transretinoico, cuyas propiedades han atraído el interés de aplicación de este insumo en el proceso de cicatrización de la piel. Objetivo: llevar a cabo un estudio de encuesta sobre la aplicación tópica de este aceite. Métodos: la investigación se desarrolló en las bases de datos electrónicas entre los meses de julio y septiembre de 2015 com las seguintes palabras clave: "Rosa Mosqueta", "wound", "Rosa aff rubiginosa", "healing" ou "Rosa canina" que incluyó artículos originales y de revisión sin. Fueron obtenidos siete artículos: un artículo de revisión, tres estudios experimentales no clínicos, un estudio clínico de diseño no experimental, un estudio de diseño casi-experimental y otro con el diseño experimental, pero todos ellos con baja calidad metodológica. Conclusiones: los trabajos evaluados indicaron que para la cicatrización de la herida por primera intención, el aceite debe ser utilizado después de 48 horas del procedimiento. El producto refinado es más estable que el crudo y tiene efectos terapéuticos incluso en baja concentración. Sin embargo, los estudios clínicos tienen sesgos metodológicos que reducen el nivel de evidencia, y no son suficientes para una recomendación terapéutica. Los estudios no clínicos mostraron que el aceite de Rosa mosqueta puede tener actividad inmunomoduladora en el lecho de la herida y promover la deposición de colágeno y organización del tejido(AU)

ABSTRACT Introduction: The oil extracted of Rose hip' seeds (Rosa aff rubiginosa or Rosa canina L.) is rich in fatty acids and transretinoic acid whose properties have attracted the interest this input in the healing process. Objective: To conduct a survey of studies on topical application of rosehip oil for wound healing. Methods: The search was conducted on electronic databases between july and September 2015 using the following descriptors: "Rosa Mosqueta", "wound", "Rosa aff rubiginosa", "healing" ou "Rosa canina", which included original and review articles. We found 7 publications: one literature review, three non-clinical experimental studies, one clinical study of non-experimental design, one study of quasi-experimental design and the other with experimental design, but low methodological quality. Conclusions: The studies show that in healing by first intention, the oil must be used 48h after the procedure. The refined oil is more stable than the crude oil and maintain therapeutic effects even at lower concentrations. However, clinical studies contain methodological bias to reduce the level of evidence and are not sufficient for appropriate recommendation. The non-clinical studies show that rosehip oil may have immunomodulatory activity in wound bed and promotes collagen deposition and tissue organization(AU)

Occupational asthma, eosinophil and skin prick tests and serum total IgE values of the workers in a plant manufacturing rose oil.

This study was aimed to determine the rate of occupational asthma (OA) in workers at a rose extracting plant. Specific clinical tests of 52 workers, randomly chosen from four local rose extracting plants, were statistically compared with the test results of 30 local control subjects of similar age and sex as the plant workers, but who had never worked in such a plant. There were no significant differences in pulmonary function tests (FVC, FEV1, FEV1/FVC, PEFR) between the control and test groups. Significantly higher serum total IgE values (p < 0.0001) were observed for the test subjects (239.08+/-240 IU/ml) compared to the control subjects (81.33+/-61.45 IU/ml). There were also significant differences (p < 0.0001) in the number of eosinophils between the control and test groups, with corresponding mean values of 2.28+/-2.75% and 0.73+/-1.72%, respectively. A specifically prepared skin prick test using a rose allergen (Rosa domescena) was positive for 53.84% in the test subjects whereas only 5.33% positive test results were seen in the control group. We have demonstrated the involvement of Rosa domescena pollen in occupational allergy, through IgE-mediated hypersensitivity. It was concluded that the workers of a rose oil extracting plant are more susceptible to the rose pollens.

Allergic rhinitis in Rosa domescena cultivators: a novel type of occupational allergy?

After the diagnosis of allergic rhinitis due to Rosa domescena was suspected in one subject with skin prick and nasal provocation tests, we recruited all other workers employed in rose cultivation in Yakaören village, Isparta. From May 2000 to July 2000 (exposure period 'time of rose handling'), we studied 600 individuals employed in rose cultivation. A questionnaire was administered by a physician, and skin testing was done by a nurse on 75 individuals suffering from asthma and/or rhinitis. Sera from these 75 subjects were available for immunologic testing. The diagnosis of atopy against rose was based on the presence of work-related symptoms, positive skin prick test (SPT) with rose extracts, and positive RAST. While no subject reported asthmatic symptoms, twenty of them reported either rhino-conjunctivitis, rhinitis or both on exposure to Rosa domescena. Fourteen of these subjects had increased specific IgE levels to Rosa domescena. Eleven (78.5%) also had a positive skin reaction to Rosa domescena. Out of the six negative sera with normal specific IgE levels to rose, only two (33.3%) had positive skin reactivity. No subject had significant daily peak expiratoy flow rate (PEFR) variations. We conclude that exposure to Rosa domescena may represent a risk for allergic rhinitis. The possibility of an occupational rose allergy should therefore be taken into consideration in the subjects working in rose cultivation.
