[Increased expression of fatty acid binding protein 4 in lungs of preterm rats after hyperoxic lung injury].

Objective: To study the expression of fatty acid binding protein 4 (FABP4) in lungs and bronchoalveolar lavage fluid (BALF) of preterm rats exposed to 60% O2 and to elucidate the relationship between the changes of FABP4 expression and the pathogenesis of bronchopulmonary dysplasia (BPD).

Methods: Hyperoxic lung injury was induced by exposing to 60% O2 in Spraque-Dawley rats within 6 hours after birth. Rats exposed to air were used as the control group.
