Acute lung injury. Two parameters of lung damage were considered 4 h after the instillation made of the protein tracer 131I-labeled albumin and either PA103 (5 × 105 CFU or 6 × 104 CFU), or PA103ΔUT (5 × 105 CFU), or no bacteria. a. Efflux of protein tracer into the bloodstream was calculated as a percentage of the total instilled amount to quantify lung epithelial injury. b. Water to dry weight ratios of lungs as index of lung edema. Data are means ± SE. n = 3 in control groups (no bacteria), and n = 5 in other groups. *, p < 0.05 versus C3H/FeJ, †, p < 0.05 versus no bacteria.
