  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.
