Influence of ingaalp laser (660nm) on the healing of skin wounds in diabetic rats

Abstract: Purpose:To determine the influence of low-power laser (660 nm) on the collagen percentage and macrophages in skin wounds in diabetic rats. Methods: 30 male Wistar rats were used, distributed in two groups: laser treated diabetic (n= 15); untreated diabetic (n = 15). The diabetes was induced by intravenous injection of alloxan into the dorsal vein of the penis, at a rate of 0.1 ml of solution per 100 g of body weight. A wound was made on the back of all the animals. Groups 2 were treated with Aluminium Gallium … Show more

“…Studies show that the LPL 7,12,13,[19][20][21] , as well as HF 9,16 , accelerate the tissue repair process for wounds, after incisional lesion, being relevant in the treatment of skin disorders, once the AlGaInP laser reduces the inflammatory reaction and provides better quality and greater speed in the repair process of soft tissue 11,15 , while the HF can intervene in the oxidoreduction balance with germicide, bactericide and antiseptic properties in the cicatrization process 9,16 . Given this, the goal was to have a macroscopic, histological and histomorphometric assessment of the process for cutaneous wound cicatrization in mice, by using AlGaInP Laser therapy compared to treatment with HF.…”

“…In this context, there is stimulation of the organism's defense and the beginning of the cicatrization, which consists in reconstructing the injured site, in order to restore the integrity and normal function 4 , besides being complex and dynamic, and involving biochemical and physiological events, which must act in harmony for the benefit of tissue restoration 5,6. However, the complex process of tissue cicatrization can be influenced, it may not occur in a successful manner and it has long been an object of study concerning the factors that affect it. In recent years, researchers have used different equipments to facilitate the healing process of skin wounds with demonstrably scientific results [7][8][9][10] . In this context, it refers to the low power laser (LPL), as AlGaInP, the AsGa and HeNe, therapeutic ultrasound,…”

“…Além disso, a presença de heterogeneidade, principalmente em relação aos parâmetros adotados entre os estudos, dificulta a avaliação fidedigna da real eficácia desta terapia 13,15,16 . Estudos prévios apontam para a eficiência da terapia a laser na aceleração do processo de reepitelização, relacionando-a à redução da atividade inflamatória e ao aumento da síntese de colágeno 2,3,17,18 . Os efeitos biológicos do laser de baixa potência têm sua função baseada em um processo fotobiológico, que consiste na absorção molecular de energia luminosa, depositada e se transforma em energia vital, produzindo, então, efeitos primários, como estimulação de linfóci-tos, ativação de mastócitos e aumento na produção de adenosina trifosfato (ATP) mitocondrial e terapêuticos gerais, os quais promovem ações de natureza analgésica, anti-inflamatória e cicatrizante 3,7,[19][20][21] .…”

“…Percebe-se uma crescente contribuição multidisciplinar para este dinâmico fenômeno fisiológico, que continua desafiando os pesquisadores [1][2][3] . Logo após o surgimento de uma lesão, há uma complexa liberação de mediadores que dão início ao processo de reparo, o qual se inicia pela inflamação, fase da migração de leucócitos e plaquetas; seguido pela fase proliferativa ou granulação, com destaque para a angiogênese e para o aumento no número de fibroblastos para produção de colágeno, elastina, fibronectina, glicosaminoglicanos e proteases que remodelam fisiologicamente a ferida; e finalmente, concluí-se com a epitelização [4][5][6][7] .…”
