Changes in weight post-infection in animals treated with intratracheal melatonin. Animals were weighed immediately prior to infection and daily until harvest. Change was calculated as a percentage of initial weight. (A) Comparison of weight retention between melatonin-treated and control CF mice. (C,D) Immune cell composition with intratracheal melatonin application. BAL fluid was used to determine (C) % neutrophils and (D) % monocytes between control and intratracheal melatonin-treated CF mice.
