Effect of Low-Level Laser Therapy (LLLT) in Pulmonary Inflammation in Asthma Induced by House Dust Mite (HDM): Dosimetry Study

Figure 4

Effect of LLLT on the production of mucus in the airways. The lungs were fixed, prepared, and stained with PAS (Periodic Acid Schif) for the analysis of mucus in the airways. The animals were irradiated with LLLT 3x/week for 5 weeks, 1 hour after challenge with HDM. Increase of × 200. Values expressed as mean and standard deviation. The groups used in the experiment are described in Figure 1. The results refer to the use of 10 mice in each experimental group. # p <0.001 when compared to the Basal group and Δ p <0.01 when compared to the asthmatic group (HDM) and ns (not significant); p<0,05 and p<0,01 when compared HDM+LLLT (3J) group with the other groups treated with other doses.
