Epithelial integrity and vascular permeabilty in the airways of mice infected with Pseudomonas aeruginosa. (a) Total protein, (b) albumin, and (c) lactate dehydrogenase (LDH) levels in bronchioalveolar lavage fluid (BALF) of control and treated animals. C57Bl/6 mice were inoculated with 105 or 106 cfu of P. aeruginosa. The mice were killed 24 (white bars) or 48 hours (black bars) postinstillation and their BALF was recovered. The graphs represent means ± SD. *P < 0.05 (versus control value); n = 5. cfu, colony forming units.
