Plasma cotinine and BAL albumin levels are elevated following CS exposure. (A) Blood samples were collected at 1 and 3 hrs after the last CS exposure and the levels of cotinine in the plasma was measured using a quantitative enzyme immunoassay kit. Data represent average concentration of three mice per condition ± SEM. (B) BAL fluids were collected at 24 hr after the last CS exposure and assayed for the presence of albumin using the albumin B test-Wako kit. Data represent the average concentration of eight mice per condition ± SEM. Statistical significance: ** = p < 0.01; *** = p < 0.001.
