Study of the strength of healing skin of rats treated with phototherapy in laser

Introduction: Laser therapy has been widely studied for its healing; however, few studies have been developed to evaluate tensile strength after phototherapy. Objective: To analyze voltage scar skin incisions in rats after laser therapy (InGaAlP-670nm). Method: Twenty rats were divided into two grou...

Objective: To analyze voltage scar skin incisions in rats after laser therapy (InGaAlP-670nm). Method: Twenty rats were divided into two groups (placebo/irradiated), underwent skin incision on the back. The irradiated group received a dose of 6J/cm2 and in the placebo group the equipment remained off. After sacrifice, three and seven days post-surgery, skin samples were subjected to tensile-histological analysis. Results: It was observed significant difference in breaking strength between groups, decrease in maximum deflection (without statistical expression), reduction of the inflammatory infiltrate and acceleration of fibroplasia and angiogenesis, consistent with increased synthesis of collagen in the area of lesions in the irradiated group. Conclusion: Therapy with low-intensity laser increases the tensile strength of the skin, enhancing tissue repair response, reducing risks of dehiscence and postoperative complications.Introdução: Terapia com laser tem sido amplamente estudada por seu efeito cicatrizante; contudo, poucos estudos foram desenvolvidos avaliando resistência à tensão pós-fototerapia. Objetivo: Analisar a tensão cicatricial em incisões cutâneas de ratos, após terapia laser (InGaAlP-670nm). Método: Vinte ratos Wistar, divididos em dois grupos (placebo/irradiado), sofreram incisão cutânea no dorso. O grupo irradiado recebeu dose de 6J/cm2 e no grupo placebo o equipamento manteve-se desligado. Após sacrifício, em três e sete dias pós-cirurgia, amostras de pele foram submetidas à análise tênsil-histológica. Resultados: Observou-se diferença significante na força de ruptura intergrupos, assim como tendência de diminuição na deformação máxima, porém sem expressividade estatística. Ocorreu redução do infiltrado inflamatório e aceleração de fibroplasia e angiogênese, compatíveis com elevação da síntese de colágeno na área das lesões no grupo irradiado. Conclusão: A terapia com laser de baixa intensidade aumenta a resistência tênsil da pele, melhorando a resposta reparacional, reduzindo riscos de deiscência e complicações pós-cirúrgicas.Universidade Nove de Julho - UNINOVE2010-08-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uninove.br/saude/article/view/226710.5585/conssaude.v9i2.2267ConScientiae Saúde; v. 9 n. 2 (2010); 179-1861983-93241677-1028reponame:Revista Conscientiae Saúde (Online)instname:Universidade Nove de Julho (UNINOVE)instacron:UNINOVEporhttps://periodicos.uninove.br/saude/article/view/2267/1738Copyright (c) 2010 ConScientiae Saúdeinfo:eu-repo/semantics/openAccessCarvalho, Kelsyanne de CastroNicolau, Renata AmadeiMaia, Antônio Luis MartinsBarja, Paulo RoxoSá, Hoctávio Pereira deSanto, Luanna Anielle Evangelista doRocha, Gilvânia Melo da2020-09-25T19:23:18Zoai:ojs.periodicos.uninove.br:article/2267Revistahttps://periodicos.uninove.br/saude/indexPRIhttps://periodicos.uninove.br/saude/oaiconscientiaesaude@uninove.br || crismonteiro@uninove.br1983-93241677-1028opendoar:2020-09-25T19:23:18Revista Conscientiae Saúde (Online) - Universidade Nove de Julho (UNINOVE)false
