Figure 2From: Liquid hyper-absorption as a cause of increased DTPA clearance in the cystic fibrosis airway DTPA absorption rate is increased in epithelial cell cultures from cystic fibrosis lungs. The mean DTPA absorption rates in well-differentiated cultures from 9 CF and 11 non-CF primary cell lines are shown (six filters averaged for each line). Asterisk, p = 0.0013 by t test. Measurements were made after the addition of 10 μL of Tc-DTPA in Ringer’s solution.Back to article page
