Desenvolvimento de nanogel de Copaifera reticulata sobre a lesão muscular em ratos usando fonoforese / Development of nanogel from Copaifera reticulata on muscle lesions in rates with phonophoresis

A copaíba (Copaifera reticulata Ducke), planta medicinal bastante usada nas regiões Norte e Nordeste do Brasil, tem difícil permeação cutânea na forma in natura, e esta permeabilidade é aumentada através do uso de nanoformulações e ainda a fonoforese, ultrassom de baixa frequência que aumenta a permeabilidade cutânea de substâncias. Sendo assim, foi analisado e comparado o efeito do óleo-resina de copaíba, in natura e de sua nanoemulsão em gel (nanogel) associado à fonoforese, na reparação muscular em ratos Wistar. Pelo método inversão de fases, formulou-se a nanoemulsão de copaíba. Esta foi incorporada ao hidrogel Carbopol® (20% nanoemulsão, 80% Carbopol®). Os animais (n = 24, machos) foram divididos em seis grupos e posteriormente foram submetidos à lesão traumática do músculo gastrocnêmio. A reparação muscular foi analisada por meio de dosagem plasmática de Aspartato Aminotransferase (AST) e Creatina Quinase (CK). Os resultados apontaram que os tratamentos de aplicação tópica do óleo-resina, de sua associação à fonoforese e desta ao nanogel foram eficazes no experimento quanto à reparação da musculatura esquelética.

Copaifera reticulata Ducke is a medicinal plants greatly employed in northern and northeastern Brazil. However, skin penetration is difficult when it is applied in natura. However, permeability increases through nanoformulations and phonophoresis and low frequency ultrasound that increases skin permeability of compounds. The effect of oil-resin of copaiba, in natura and in gel (nano-emulsion), associated to phonophoresis, was analyzed and compared for muscle repair in Wistar rats. Copaiba nano-emulsion was formulated by phase inversion. It was incorporated to hydrogel Carbopol® (20% nano-emulsion, 80% Carbopol®). Male animals (n=24) were divided into six groups and later underwent traumatic lesion of the gastrocnemius muscle. Muscle repair was analyzed by plasmatic dosage of aspartate aminotransferase (AST) and kinase creatine (CK). Results show that topic treatments with oil-resin, associated with phonophoresis and nanogel were efficient in the assay for the repair of skeleton muscles.

Medida computadorizada da evolução da área cicatricial tratada com ultrassom terapêutico e citrato de sildenafila / Computerized measurement of the evolution of cicatricial area treated with ultrasound and sildenafil citrate

Objetivou-se comparar a evolução da cicatrização de feridas cirúrgicas com cinco protocolos de tratamento através de análise planimétrica. Grupos de 12 ratos Wistar, foram alocados em cinco estudos experimentais: A- controle negativo; B- ferida cirúrgica, tratada com ultrassom terapêutico (UST) desligado ; C- ferida tratada somente com citrato de sildenafila ; D- ferida tratada com citrato de sildenafila e UST e grupo E-ferida tratada somente com UST. A evolução cicatricial foi acompanhada diariamente e avaliada por imagem fotográfica computadorizada aos sete, 14 e 21 dias. A aplicação do UST pulsado, com doses 1MHZ e 0,4Wcm2 reduziu o tempo de cicatrização epitelial em condições experimentais, favorecendo precocemente a reparação tecidual com efeitos qualitativos superiores ao tratamento com citrato de sildenafila (CS). A mensuração computacional para evolução da cicatrização de ferida dérmica mostrou-se um recurso de fácil aplicação sendo de baixo custo e eficiente para a aplicabilidade na rotina médica veterinária.

This study aimed at comparing the evolution of healing of surgical wounds with five treatment protocols through planimetric measurement. Groups of 12 Wistar rats were allocated in five experimental studies: A ­ negative control; B ­ surgical wound treated with therapeutic ultrasound turned off; C ­ surgical wound treated with sildenafil citrate; D ­ wound treated with sildenafil citrate and therapeutic ultrasound; and group E ­ wound treated only with therapeutic ultrasound. The healing progress was monitored daily and assessed by computed photographic image at seven, 14 and 21 days. It was concluded that the application of pulsated therapeutic ultrasound on surgical wounds at 1 MHz and 0.4Wcm2 doses reduces the epithelial healing time in experimental conditions, favoring the early repair of tissue with qualitative effects superior than the ones found in the treatment with sildenafil citrate (SC). The computational measurement for the evolution of the dermal wound healing proved to be an easy-to-apply resource, with a low cost and great efficiency for the applicability in the veterinary medical routine.

Comparative efficacy of analgesic gel phonophoresis and ultrasound in the treatment of temporomandibular joint disorders

Aim: The aim of this study is to determine the efficacy of phonophoresis in patients with temporomandibular disorders. Objective: To prove that phonophoresis could be an effective treatment modality in in patients with temporomandibular disorders. Procedure: Fifty patients diagnosed clinically and radiographically as temporomandibular disorder were randomly assigned into either of the two groups, namely, (Group A) plain ultrasound and (Group B) phonophoresis. Acoustic gel containing no pharmacological agent was applied in the ultrasound group, whereas a gel containing aceclofenac was applied in the phonophoresis group. Each group was treated three times a week for 2 weeks. The assessment of pain and inflammation both before and after treatment were done using the visual analog scale (VAS) and Creactive protein (CRP). Results: Intergroup comparison was done and analyzed statistically using independent ttest. Intragroup comparison was done using paired ttest. A significant difference in VAS scores and CRP levels before and after treatment were seen within both ultrasound phonophoresis PH groups. No significant difference was noted statistically between ultrasound and phonophoresis group. Conclusion: The results of this study suggests that though plain ultrasound as well as phonophoresis with aceclofenac gel are effective in the management of temporomandibular disorders. Phonophoresis was found be slightly superior as evident in VAS scores and CRP levels though not statistically significant.

Anti-inflammatory and antinociceptive effects of phonophoresis in animal models: a randomized experimental study

The aim of this study was to evaluate the therapeutic effects of ultrasound (US)-mediated phonophoresis alone or in association with diclofenac diethylammonium (DCF) administered topically in animal models of inflammation. A pre-clinical, prospective, and randomized experimental study of quantitative and qualitative nature was carried out. Phonophoresis was performed using a therapeutic ultrasound apparatus in two distinct models of acute inflammation. Edema was induced by an intraplantar injection of carrageenan and measured by plethysmography. The Hargreaves test was used to evaluate the antinociceptive activity and investigate the action of phonophoresis on tumor necrosis factor (TNF)-α production. A histological analysis with hematoxylin-eosin was used to evaluate tissue repair, and the expression of COX-2 was determined by immunohistochemical analysis. At the peak of inflammatory activity (3 h), treatment with US, US+DCF, and DCF significantly reduced edema formation compared to the control group. Treatment with US+DCF was more effective than treatment with US alone at both analyzed times. In the analysis of the antinociceptive activity, the treatments significantly increased the latency time in response to the thermal stimulus. Histopathological analysis revealed a reduction of the inflammatory infiltrates and immunohistochemistry demonstrated that the association was effective in reducing COX-2 expression compared to the control group. The association of DCF with US produced anti-inflammatory and antinociceptive effects in rat models of inflammation, which may be associated with inhibition of COX-2 and TNF-α production.

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 (0,2/0,4/0,6/0,8/1,0W/cm2), em 1mim/cm2. Os dados receberam tratamento estatístico pelo software BioEstat 5.3 e foi admitido um nível de significância de ≥0,05. No modo contínuo e na intensidade de 0.2W/cm2 o gel foi considerado "Bom transmissor", na intensidade de 0.4 W/cm2 e 0.6W/cm2 um "Transmissor moderado" e nas intensidades de 0.8W/cm2 e 1.0W/cm2 um "Transmissor pobre". Concluiu-se que o gel de C. duckei 10% não atenuou as ondas de US em nenhum modo ou intensidade testado. E pode assim ser adicionado a esse para tratamentos sendo considerado transmissor bom ou moderado de acordo com a intensidade do US.(AU)

Effectiveness of Electrophysical Modalities in the Management of Temporomandibular Joint Disorders: A Review.

This review was conducted by three investigators to assess the scientific evidence and eff ectiveness of various electro physical modalities in the treatment of temporomandibular joint (TMJ) disorders. This review was conducted by three investigators. The databases of PubMed, Science direct, Cochrane clinical trials register (June 1994-Jan 2013) were electronically searched for the key terms TMJ disorders with low-level laser therapy (LLLT), iontophoresis, phonophoresis, therapeutic ultrasound, transcutaneous electric nerve stimulation, microcurrent electrical nerve stimulation. The retrieved titles were thoroughly evaluated, and full text was obtained. Based on the inclusion and exclusion criteria the selected studies were assessed for the quality evidence of the trails using the Grade Pro 3.6 version software and summary of finding table was generated. Of 1544 titles, 28 full text publications, which were eligible for this review were included, and 15 randomized placebo controlled trials that were fulfilling the set criteria. Out of 15 studies 10 are performed on LLLT, 2 on iontophoresis, 1 on pulsed radiofrequency energy, 1 on cathodal high voltage electric stimulation and 1 on laser acupuncture. LLLT is the extensively practiced electrophysical treatment modality with the moderate quality of evidence. Electrophysical modalities are helpful as adjuvant in the treatment of TMJ symptoms. However, there are no evidences to conclude that a single electrophysical modality is beneficial over the other in the temporomandibular disorders management.

Introdução: A tendinite calcária do ombro é uma calcificação caracterizada pela deposição de sais de cálcio nos tendões do manguito rotador, provocando dor no ombro e perda de amplitude de movimento (ADM). O ultrassom é sugerido como alternativa promissora para facilitar a reabsorção dos depósitos de cálcio. Os mecanismos que fundamentam esse efeito são, entretanto, ainda controversos na literatura, e a utilização clínica do ultrassom na tendinite calcária tem sido baseada mais em evidências empíricas do que científicas. Objetivos: Realizar uma revisão bibliográfica sobre os efeitos biológicos e terapêuticos do ultrassom, a fim de identificar o real papel desse recurso no tratamento da tendinite calcária do ombro. Materiais e métodos: Para sua elaboração, foi feita uma busca bibliográfica em bases de dados eletrônicas e uma pesquisa manual. Resultados: Dentre os estudos selecionados, dois demonstraram redução da dor e do tamanho da calcificação e dois não apresentaram resultados positivos. Discussão: Os benefícios promovidos pelo ultrassom são dependentes dos parâmetros utilizados. Variáveis como o tamanho da área a ser tratada, diferenças teciduais, duração da aplicação e o objetivo da conduta terapêutica também devem ser considerados. Conclusão: Com base nesta revisão, pode-se afirmar que o ultrassom terapêutico é um recurso efetivo no tratamento da tendinite calcária do ombro.

The ultrasound is suggested as a promising alternative to facilitate the reabsorption of calcium deposits. The mechanisms underlying this effect are still controversial in literature and the clinical use of ultrasound in the calcifying tendinitis has been based more on empirical evidence than scientific. Objectives: To review the ultrasound biological and therapeutic effects for the purpose to identify the true role of this resource in the treatment of calcifying tendinitis of the shoulder. Materials and methods: It made a literature search in electronic databases and a manual research. Results: Among the selected studies, two demonstrated pain and size of the calcification reduction and two studies not showed positive results. Discussion: The benefits promoted by ultrasound are dependent on parameters used. Variables such as the size of treated area, tissue differences, duration of application and therapeutic aim should also be considered. Conclusion: Based in this review, it can be affirmed that ultrasound therapy is an effective resource in the treatment of calcifying shoulder tendinitis.

Tratamento da hiperidrose palmar com onabotulinumtoxinA veiculada por iontoforese ou fonoforese: relato de casos / Use of iontophoresis or phonophoresis for delivering onabotulinumtoxinA in the treatment of palmar hyperidrosis: a report on four cases

Hiperidrose palmar idiopática é doença frequente, que tem grande impacto na qualidade de vida dos pacientes, e seu tratamento definitivo (simpatectomia) associa-se a risco cirúrgico e efeitos adversos. Fármacos, como onabotulinumtoxinA, podem ser veiculados percutaneamente por iontoforese ou fonoforese e contribuir no tratamento da hiperidrose. Os autores apresentam quatro casos em que houve melhora objetiva e subjetiva da sudorese após dez sessões consecutivas de iontoforese ou fonoforese, sem evidências de efeitos adversos. Os resultados clínicos mantiveram-se por 16 semanas de observação após a interrupção do tratamento. Técnicas de veiculação percutânea de medicamentos devem ser percebidas como opções nos tratamentos dermatológicos.

Idiopathic palmar hyperhidrosis is a common disease that exerts a considerable effect on patients' quality of life. The definitive treatment of this condition (sympathectomy) is associated with some adverse effects and surgical risks. Drugs such as onabotulinumtoxinA can be percutaneously delivered by phonophoresis or by iontophoresis and may be useful in the treatment of hyperhidrosis. In this paper, the authors describe four cases in which an objective and subjective improvement in sweating was seen following 10 daily sessions of phonophoresis or iontophoresis. No adverse effects were reported. The clinical results achieved with treatment were maintained over 16 weeks of follow-up after the end of treatment. Percutaneous drug delivery techniques should be perceived as an option for the treatment of dermatologic conditions.

Efeito do gel da babosa (Aloe barbadensis Mill. ) associado ao ultrassom em processo inflamatório agudo / Effect of aloe (Aloe barbadensis Mill. ) gel combined with ultrasound in the acute inflammatory process

O presente trabalho teve por objetivo analisar a ação antiinflamatória do gel da Babosa a 2 por cento (Aloe barbadensis Mill.) associado ao Ultrassom pulsátil no modelo de edema de pata. Foram utilizados 25 ratos Wistar, (200-250 g), divididos em 5 grupos de 5 animais cada. Grupo1 (controle): ratos tratados com solução salina a 0,9 por cento; Grupo 2: ratos tratados topicamente com gel de A. barbadensis Mill. a 2 por cento; Grupo 3: animais tratados com Ultrassom; Grupo 4: ratos tratados com gel de A. barbadensis Mill. a 2 por cento associado ao Ultrassom; Grupo 5 (controle positivo): ratos tratados com Indometacina na dose de 5 mg Kg-1. Os animais dos grupos 1 e 5 receberam os respectivos tratamentos por via intra-peritoneal 30 minutos antes da injeção intra-plantar de carragenina e os grupos 2, 3 e 4 foram tratados por aplicação tópica de gel de A. barbadensis Mill. a 2 por cento, Ultrassom pulsátil e gel de A. barbadensis Mill. associado ao Ultrassom respectivamente 15 minutos após a indução do edema. Os animais do grupo 04 demonstraram redução significativa do edema quando comparados ao grupo controle, ao mesmo tempo, que se mostrou comparável à indometacina. Observou-se que o gel de aloe associado à fonoforose é capaz reduzir a formação do edema de pata em ratos.

This work aimed to evaluate the anti-inflammatory action of 2 percent aloe (Aloe barbadensis Mill.) gel combined with pulsed ultrasound in the paw edema model. Twenty-five Wistar rats (200-250 g) were divided into 5 groups of 5 animals each. Group1 (control): rats treated with 0.9 percent saline; Group 2: rats topically treated with 2 percent aloe gel; Group 3: rats treated with ultrasound; Group 4: rats treated with 2 percent aloe gel combined with ultrasound; Group 5 (positive control): rats treated with indomethacin at 5 mg Kg-1. Animals of groups 1 and 5 were intraperitoneally treated 30 min before intraplantar carrageenan injection and groups 2, 3 and 4 were treated by topical application of 2 percent aloe gel, pulsed ultrasound and aloe gel combined with ultrasound, respectively, 15 min after edema induction. Animals of group 4 had a significant reduction in edema relative to controls and showed to be comparable to indomethacin. Aloe gel combined with phonophoresis is capable of reducing paw edema formation in rats.

Efeito do ultrassom associado ao gel de calêndula sobre a atividade reparadora em lesões musculares experimentais / Effect of ultrasound associated with calendula gel on restorative activity in experimental muscular injuries

Diversas técnicas têm sido propostas para o tratamento de lesões musculares, sendo a do ultrassom terapêutico uma das mais utilizadas. Além dos efeitos do ultrassom, este facilitaria, ainda, a permeação de drogas pelos tecidos (fonoforese). A calêndula é um fitoterápico que apresenta atividade cicatrizante empregada popularmente no tratamento de lesões. O objetivo deste estudo foi avaliar a eficácia do ultrassom, da fonoforese e a influência da aplicação tópica do gel extraído da Calendula officinalis na recuperação de lesão muscular experimental em ratos. A análise histológica do músculo e a determinação da área de lesão foram realizadas após o músculo tibial anterior lesionado ser tratado durante cinco dias. Os resultados indicaram que todos os grupos tratados com ultrassom e calêndula apresentaram melhor resolução da lesão, por apresentarem maior quantidade de fibroblastos, neovascularização e mioblastos em relação ao Grupo-controle. Quanto à área de lesão, somente o grupo em que foi associado o ultrassom à calêndula apresentou uma área significativamente menor. Em conjunto, os dados obtidos demonstram que, no modelo experimental estudado, a fonoforese apresentou-se mais indicada para o tratamento de lesões musculares

Several techniques have been proposed as treatment for muscular injuries, and therapeutic ultrasound is one of the most used. Besides the effects of ultrasound, it also facilitates drug flow trough the tissues (phonophoresis). Calendula is a phytotherapic which presents healing elements, popularly used on injury treatments. The objective of this study was to evaluate ultrasound effectiveness, phonophoresis, and the influence of the topic application of the gel with Calendula officinalis extract, in the recovery from experimental muscular injury in rats. After the injured front tibial muscle was treated during five days, a histological analysis of the muscle was performed and the injury area was determined. The results indicated that all the ultrasound/Calendula-treated groups presented better evolution in the injury, sinasce they presented more fibroblasts, neovascularization and myoblasts in relation to the control group. As to the injured area, only the group in which the ultrasound was added to Calendula presented a significantly smaller area. In all, the obtained data demonstrate that in the experimental model studied, phonophoresis was more indicated for muscle injury treatment
