Figure 3From: Response of spontaneously hypertensive rats to inhalation of fine and ultrafine particles from traffic: experimental controlled studyCorrelation between heme oxygenase-1 present in bronchoalveolar lavage fluid versus heme oxygenase-1 present in lung homogenate. All animals were exposed to fine, concentrated, ambient particulate matter. Regression: Y = -0.15 + 0.217*X, correlation coefficient = 0.79.Back to article page
