Anti-inflammatory effect of low-intensity laser on the healing of third-degree burn wounds in rats.

Third-degree burn wounds are considered severe injuries because they destroy all the skin layers and may affect subcutaneous tissues, fasciae, muscles, and bones. To favor the healing process of the injured tissues, it is very useful to diminish the occurrence of the inflammatory process. The present study was aimed at comparing the effect of different energetic densities of AlGaInP laser on the inflammatory process and in the healing of third-degree burn wounds in Wistar rats. This study was approved by the Ethics Committee, in which 36 adult male rats were selected and suffered the induction of third-degree burn injury. These rats were divided as follows: group 1-control (treated with silver sulfadiazine), group 2-received energy density of 3 J/cm(2), and group 3-received energy density of 6 J/cm(2). All animals daily received an occlusive bandage with silver sulfadiazine and 8 % papain. The laser therapy was performed alternatively three times a week. The animals were evaluated on the 3rd, 7th, 14th, and 21st days after the initial lesion and euthanized for the macroscopic, histologic, and morphometric analysis. A higher production of collagen was observed at 7 days and a greater re-epithelialization at 21 days in group 3 (6 J/cm(2)). Furthermore, the latter when compared to the other groups presented macroscopically a better aspect of the scar at 21 days with more granulation tissue and fibrosis. We conclude that the AlGaInP laser used in dosages of 3 and 6 J/cm(2) favors the healing of third-degree burn wounds induced in rats.

A importância da Liga Acadêmica de Queimaduras / The importance of the Burns Academic League

A abordagem da fisioterapia em queimaduras ainda é escassa em nosso país, porém muito necessária. Partindo deste princípio foi idealizado um projeto que visava apresentar o conteúdo sobre queimaduras aos acadêmicos da área de saúde e educação e trabalhasse em prol da prevenção de acidentes que envolvessem queimaduras. Dessa idéia surgiu a Liga Acadêmica de Queimaduras, que completa um ano de funcionamento, e vem apresentar seu trabalho científico e social desenvolvido neste primeiro ano de atuação. Obtivemos um resultado positivo, conscientizando a comunidade e envolvendo os acadêmicos no trabalho científico e social voluntário.

The approach of physical therapy in burns is still scarce in our country, but very necessary. Assuming this was planned a project to present the content on burns to the students of health care and education and works towards the prevention of accidents involving burns. Based on this idea was launched the Burns Academic League, that has one year of operation, which scientific and social activities are presented in this paper. Positive results were obtained, educating the community and involving students in scientific and social activities.
