Low Level Laser Therapy Reduces the Development of Lung Inflammation Induced by Formaldehyde Exposure
Fig 5
Treatment with LLLT increases IL-10 gene expression and did not alter IL-6 gene expression in the lung tissue after FA exposure.
Group of rats was exposed or not to FA inhalation (1%, 90 min/day, 3 days) and treated or not with LLLT (30mW, 1.8 J, 60s/point, total 540s, 1 and 5h post each FA inhalation). Non-manipulated rats were used to obtain basal parameters. The evaluation of gene expression of inflammatory cytokine IL-6 (A) and anti-inflammatory IL-10 (B) in the lung were determined 24 h after the last FA exposure. Data are mean ± SD of 6 animals per group. *P<0.05 in relation to B group; θP<0.05 in relation to FA group (Panel B).
