Table 2 LED treatment did not reduce the mucus production as wells as oedema, but partially reduced the perivascular and peribronchiolar cell infiltration after LPS injection.

  1. Groups of mice were induced to ALI by ip injection of LPS and treated or not with LED 2 and 6 h after induction. Non-manipulated and LED treated mice were used as control. After 24 hours of ALI induction the histological analysis was performed. Data mean ± SEM of 6 animals per group. *P < 0.05 in relation to B group; θP < 0.05 in relation to LPS group.
