Avaliação da transmissibilidade ultrassônica do gel fitoterápico de Copaifera duckei Dwyer

Abstract

RESUMO.-Esse estudo teve por objetivo avaliar o potencial de transmissibilidade ultrassônica de um gel fitoterápico de copaíba da espécie Copaifera duckei Dwyer na concentração de 10%. A pesquisa foi registrada junto ao Sistema Brasileiro de Biodiversidade. O gel fitoterápico de Copaifera duckei 10% foi manipulado de acordo diretrizes da Farmacopéia Brasileira e testado em um aparelho de Ultrassom (US) operado na faixa de 1 MHz. Como grupos controle foram selecionados a água destilada e o gel hidroalcoólico. A análise ocorreu de forma qualitativa e quantitativa através do modelo proposto na literatura. O US foi programado para modos de corrente pulsado/contínuo e testados nas intensidades (0,2/0,4/0,6/0 This study aimed to evaluate the potential of transmissibility of an herbal gel of Copaifera duckei Dwyer at a concentration of 10%. The research was registered with the Brazilian Biodiversity System. The gel of Copaifera duckei 10% was guidelined by the Brazilian Pharmacopoeia and tested on an Ultrasound device (US) operated in the range of 1 MHz. The control groups were selected distilled water and hydro alcoholic gel. The analysis was qualitatively and quantitatively using the model proposed in the literature. The US was scheduled to current modes pulsed/continuous and tested in the intensities (0.2/0.4/0.6/0.8/1.0W/cm2) in 1mim/cm2. The data received statistical treatment by BioEstat software 5.3 and was admitted to a significance level of ≥0.05. In continuous mode and intensity of 0.2W/cm2 gel was considered "good transmitter" at the intensity of 0.4W/ cm2 and 0.6W/cm2 a "moderate Transmitter" and the intensity of 0.8W/cm2 and 1.0W/ cm2 a "poor transmitter". It was concluded that the 10% gel C. duckei US did not attenuate US waves in any form or intensity tested; it can thus be used for this treatment being considered a good or moderate transmitter according to the intensity of US.

GC-MS Chemical Characterization and In Vitro Evaluation of Antioxidant and Toxic Effects Using Drosophila melanogaster Model of the Essential Oil of Lantana montevidensis (Spreng) Briq.

“…β-caryophyllene (28.15%), one of the major component of L. montevidensis leaf essential oil, is a sesquiterpene present in essential oils of several plants families. Plants species that have this constituent exhibit a variety of pharmacological activities such as anti-inflammatory, antinociceptive, and antioxidant, among others [49,50,51]. d -germacrene (31.27%), the major component found in L. montevidensis leaf essential oil, is a common compound in plants, being considered a precursor for the biosynthesis of many sesquiterpenes [52].…”

Análise da ação do gel enriquecido com alfa-terpineol associado ao ultrassom pulsátil na tendinite aguda em ratos Wistar

“…De acordo com Chorilli et al 32 , a intensidade e frequência interferem na transmissibilidade das ondas de forma proporcional, quanto maior elas são maiores são os índices de transmissão das ondas de ultrassom. Diante dessa perspectiva Marinho et al 33 avaliaram o potencial de transmissibilidade ultrassônica do gel de Copaifera duckei Dwyer a 10% e concluíram que o modo pulsado 50% apresentou melhores resultados, comprado ao modo pulsado 20%, assim, sugerindo que a transmissibilidade é maior quanto maior for à frequência de exposição sobre a pele.…”

Therapeutic ultrasound associated with essential oils of copaiba and tea tree for healing skin lesions

“…In this study, the gel with copaiba and tea tree EOs was used in association with ultrasonic therapy. In other studies 15,16 , copaiba oil showed positive transmissibility In an Asian study, results showed that the application of LFUS in wounds caused by diabetes promotes the expression of endothelial growth factor, transforming growth factor, inhibits the expression of interleukin and tumor necrosis factor 21 .…”
