Figure 1From: Cytosolic phospholipase A2α mediates Pseudomonas aeruginosa LPS-induced airway constriction of CFTR -/- mice Induction by LPS instillation of airway constriction in CFTR-/- mice. Mice were kept in whole-body plethysmography system to measure basal level of Penh for 40 min. Then, they were subjected to intranasal instillation of either LPS (330 μg/kg) or the same volume of saline. Penh was measured continuously for 4 h and data were collected every 10 seconds and expressed as means of every 3 min. A representative graph is shown in A. The means of Penh values at the interval periods between 200 to 300 min were presented in B. * p < 0.05 LPS-treated CFTR -/- vs LPS-treated CFTR +/+ mice; ** p < 0.01 LPS-treated vs saline-treated CFTR -/- mice. †† p < 0.01 LPS-treated vs saline-treated CFTR +/+ mice.Back to article page
